Ive been searching and reading info about this Mafless Tuning for my Eurospec M3, but Im still undecided, the maf sensor is supposed to tell the ecu the amount of air coming into the intake manifold, If you remove this sensor, and just give the ecu a fixed value, how does it benefit the engine if the amount of air can still vary ?

How does the ecu deal with barometric changes without the MAF ? If you travel to the mountains, lets say 2800 meters above sea level, how will the engine behave ? there is way less oxigen up there, the air is a lot thinner...

I got this info from AutoHut.nl :


Dear mr. Onate,

Many thanks for your email regarding the chips for driving Alpha-N.

The Street engine of the M3 is build for performance but also driveability
on the daily drive basis. The MAF sensor sees how much air is going in the
car and mixes fuel and air for driving in a mix to guarantee economic
driving.

Alpha-N is the base of running the engine. This 'shortcuts' the MAF sensor,
so as much as possible air is going in to the engine through the airbox.
This way you will have a rich mixture of fuel and air in the engine.
Combined with the better and higher airflow of the airbox you will gain much
more HP.

We also drive a BMW E36 M3 3.0 from 1993 with the CF airbox. We now have
around 300-310 HP on that car. We drive it also on a daily basis. With this
chip and airbox you will gain more HP and you will feel and hear it!

If you have any question at all, don't hesitate contacting me.

Met vriendelijke groet,
Best regards,

I sent them another email, regarding this issue, but id like to hear your opinions as well, thank you in advance.

Instead of a MAF, Alpha-N uses RPM and TP as the primary inputs to the ECU to calculate the necessary injector time. Typically there will also be a separate barometric sensor for compensation (and an O2 sensor, water temp air temp...etc).

Alpha-N works great, but is more time consuming to tune. MAF based tuning is easier since you directly know the airflow from the MAF output, but MAF's are slow to respond and their dynamic range is limited.

I tuned a couple of MoTeC units with Alpha-n in college on CBR600 motors, but have never messed with converting MAF to Alpha-n.

Maybe someone else with more experience will chime in.

Some factory cars do not use a mass airflow sensor. You need at least a couple to run the car well, but you do not need them all. For example, there are TPS, MAP, MAF or HFM or AMM, and IAT. Many Bosch and some other ECU are set up with universal features that are not used in every application -- for example the MAP ability may be there but might not be used on a particular engine.

Ideally, you do not want a very strict tuning program that fits only the exact modifications you have and only when everything is working perfectly. This is why the MAF or HFM or AMM is so popular. It measures load and load can vary under conditions, with different modifications, and even from engine to engine in the same model car. The price for it is a small restriction in airflow since all the air has to pass through it and some of it hits the sampling film or sensor.

AA has tuned USA model E46 M3 to run Alpha N. RMS has tuned E36 M3 to run with MAP instead of the HFM or AMM or MAF. Other people have installed aftermarket systems like the Megasquirt that do not use the HFM or AMM or MAF. There are even aftermarket piggyback units that do away with the HFM or AMM or MAF. HKS makes one called the VPC or Vein Pressure Converter that replaces the MAF or AMM or HFM with a MAP and I am sure there are similar devices.

You can have very good driveability without one, but you do want to ask what would happen if you make some more modifications. Will the system still be able to adjust or will you have to retune it.

I have the H&H Alpha N chips from autohut in my car, it still reads IAT sensor, and O2 sensors, as well as predicting fuel and timing based on throttle position and RPM, it also reads engine temp etc, as it is 100% civilised on cold starts etc, I have no hesitation at all in recomending it, drivabilty is as good as stock, with more hp, particularly at top end, on dynojet, I would be ~300whp and can still drive through city traffic at 40mph in 5th gear if I want to

Thanks for the input guys, I got this other email from them....

Hello,

The set comes with 2 chips.

The chips don't come with switches or buttons. It just maximizes the Air
ratio as much as possible for the airbox.

For example if you drive the car with the airbox without the alpha-n chips,
the car might stutter because it gets too much air for the standard
fuelratio. With these chips you get a higher ratio resulting in much more
power and torque.

So it comes with two chips ? I guess for different setups, maybe air volume, or temp ? or different altitude ? :confused

Or do you install the two chips at the same time on different sockets ? :confused

Alan, do you drive your car only on the "sea level" ? Sidney its in the coast right ?

When you order it, did you have to give details of your mods ? I mean is the chip personalized for each car ? how flexible is it with other mods you do in the future ?

Does it remove speed limiter ? does it "touch" vanos in any way ?

Thanks again

:buttrock

the 2 chips, 1 is for main ecu, the other is vor vanos computer, I live in western Victoria, in the Grampians mountain range, far from sea level, but visit my kids in Adelaide, and drive to other sea level places, I have also raced on racetracks at sea level, and in central highlands, and have had zero problems, it is slightly rich, cams would solve that (I also have 2 fuel pumps running to eliminate fuel surge on race track which causes it to run slightly rich)
the chips are a direct copy of what H&H racing used to use and sell, they will work very well with stock S50B30, but would be optimized if you ran free flow exhaust and big cams etc. speed limiter is disabled and rev limiter is raised

Awesome thanks, thats just the info I needed

:buttrock

i will be running cf airbox and a staight thru exhaust...

Ok, heres some more info...

The chips change the following:

- Max RPM 8000
- Removes speed limiter
- Vanos timing changed
- AFM deleted
- The system is changed to super+ fuel
- Timing curve is changed

hey man...plz post back when u install them bcz am thinkin about getting them for my car....
so ur getting the 2 chips and the carbon air box???

psh, you guys and your alpha-n tunes...i just unplugged my MAF and called it a day :redspot


...i'm not joking.

yes, I just paid last week, both chips should be here in two weeks from Netherlands, the CF plenum is coming from Hong Kong also

I have an AA chip for 3.5" HFM, 17.5 injectors. After installing ti and driving for a couple hours, I popped the hood to find I never plugged my HFM in..... seemed to run fine. I haven't tried to unplug it again and see what would happen.... maybe I will.

for what its worth, I accidentally unhooked my HFM from the harness and my car wouldn't even idle, and I got an immediate CEL.

I just tested unplugging the maf on my car (I had my brother test it on a 99m) and another and both CEL lights came on the instant the cars were started.

i didn't say i don't have a CEL...i definitely do. i just ignored it. as far as the people who tried it and had idle issues, i have them too. every once in a while when i come to a stop the car will just stall. at this point i've grown used to it and it doesn't happen all the time so it's not that bad. i was pretty nervous about running my car without a MAF, but the hard-coded map on the car seems to work better than with the MAF. but hey, this may not apply to all cars. definitely do this at your own risk.

I don't want to go too much on this thread but everytime i've encountered CEL on other BMWs, the car seems to go into a 'limpmode'. I know you've shown that the car runs good and that it actually corrected your a/f, but I'm hesitant to try and run full throttle with a CEL on.

I may dyno my car on Thursday, I'll do one run with the maf unplugged just for this thread.

Just want to point out that that the original question is from an owner with a Euro M3, as was the useful reply from the owner in Australia. What's available and works for them doesn't necessarily apply to US spec cars.

BMW currently uses Alpha-N engine management on some of its bikes, and apparently will on the new V8 E90 M3.

I think I'm going to order these H&H chips. They're so cheap and they would provide a solid basis for a tuner stateside to provide me with a custom alpha N and vanos map.

Single vanos S50 B32 3.2L with alpha N and GS cf airbox. Should be interesting...

CHEERS! :buttrock

what difference does it have if u unplug the maf slowly while giving the engine throttle.

I have a euro 321hp m3 (3.2ltr) and the car runs reasonably well with mo MAF, but uses significantly more fuel. it seems to go a bit harder at the topend, but i need to get near a dyno to test it fully..........YES its not a US m3 and what works with my car prob wont work with the US one

GazM3 dude, i dont know exactly, but if i unplug the MAF quickly at idle, itll sometime take time(we're talking milliseconds here) to switch between maf-based MAP and the alpha-n map .. and the car stutters for a second .. if u dont give it throttle sometimes itll stall in this switching time .. u see ?

about ur m3, i have the same engine as you do, and if you choose to believe me .. im telling u at idle AFRs went from 14.7:1 to 11.5:1 ...
on the dyno i made ~10bhp more by unplugging the MAF
so to daily drive without a MAF would cost too much fuel consumption

I just got a s50b30 in my garage, just waiting to be installed :buttrock. It already has full SS exhaust from headers on back & all other stuff (pulleys, fan delet, gt runners, ect...). I'm debating whether these chips will still run good once I put in some 284 schricks as I have planned. If anybody has this set up or knows anyone else that does I would like to hear more input. I need more info. before I decide to go the alpha n route, so this doesn't turn into headache in the future.

I don't think it's a stretch to presume H&H tuned for Schrick 284 cams since they are the most prevalent cams out there, especially in the 90s.

(Many German tuners offer "our sport", "our performance", or "our specially tuned" cams at a premium. Only after receiving them does the owner realize they're Schricks. :mad)

At 210 euros shipped, you will get a decent starting point that you can have fine tuned by software tuners in North America (eg. Mark D'Sylva) by providing them with wideband sensor AFR logs. I need to contact the above tuner about alpha n programming. It may be better to just get the tune from him instead if he can do alpha N.

If you're also interested in purchasing these chips, then perhaps we can get a discount by ordering 2 sets?

Thanks, for the response your input is very informative. To elaborate more on my current mods, I have the following:

GT runners
custom intake
evosport pulleys (on order, are these the only brand available???)
fan delete (I think, since there is no motor fan & i already have a SPAL fan)
SS headers
SS midpipe with twin resonators
SS exhaust
custom AA chips (Vanos & DME)
It might have GT cams,but I have to confirm that with the previous owner


Please keep me posted on your plan to get it costumed tuned, I'm down to split the cost if it's reasonable. Maybe I'm ignorant, but the chips from autohul are straight copies of the H&Hs chips. I heard that their setup used to consist of schrick 296 cams, aftermarket full exhaust, & other mods I don't know about. I’ve read various post of other members saying that they work extremely well stock & with light bolt ons, but I have never heard of anyone using them with any type of schricks cams:help

Well, I guess evosport is the only way to go with pullies then. Just keep me posted on the alpha n chips.

Regarding the AA chip the PO(onelap) told me before I bought the motor that he had purchased the motor from AA & they sold him the software for his motor with mods.

You realize the cable doesn't care how fast or slow you remove it - it's a circuit, it has an ON and an OFF... are you sure you guys should be messing with unplugging MAFs?


Unplugging a MAF is not Alpha-N. You are simply running open-loop with no fuel trimming! Its a waste of fuel! Alpha-N has no use but on ITB/Large duration cam engines - US S50/S52 do not require alpha-N and the only gain you'd pick up is the gain of not having a MAF, which is the same diameter as your intake hose so it's moot. Alpha-N is harder to tune but even harder to tune for drive-ability. Please guys research what you're doing - do not waste your time with "unplugging the MAF slowly" this is ridiculous.

Back to the eurospec scenario..... Alan, do you know how exactly is the vanos affected by this chip ? Euros have continuous vanos, as opposed as the two step vanos the us spec has, so what does the chip do there ?

As ive heard the vanos chip force the vanos to run from low end....i dunno if thats true but if its wouldnt that just wear out the vanos...specially that our euro engines has a very sensitive vanos system....

Just asked the guy for Alpha N and Nitrous Oxide compatibility and heres what he answered...

Hello,

Sorry, I didn't add instructions for it. You can easily unscrew the ECU behind the glovecompartment. IF you open the ECU you will see the chips you need the change.

Our chip builder says you should not use this chip with NOS. Maybe it can be used, but he has no experience with it.

I guess timing curve is too agressive, damn I forgot to ask that before I bought my direct port setup :(When you mentioned above that you bought a direct port nitrous setup as well as alpha N chips, I was wondering how you planned to run them together. Sounds like a recipe for disaster.

Can you provide more details on your nitrous setup?

the key with N20 is you have the fuel delivery capability of the upgraded power level, and a small matter of wether the engine internals are up to the task also. with a direct port setup its gunna be an awful lot of additional power for a std engine to cope with

I bought a NX Direct Port WET nitrous oxide system, with all the security switches you can think of (well most of them) and I was thinking for a 50 or 75 hp shot to be safe, ive heard euro engines can take shots up to 100 hp with stock internals, and a direct port system, they dont recommend going higher that 50 on the "one nozzle" setups, since the first cylinders have the tendency to go lean with those... the direct port WET systems prevent that from happening.

But now that ive added the alpha N chips, im thinking about it.... I dont know if I should try it :(

that nitrous is probably really bad.....


send it to me to be safe :stickoutt

+7 for the euro section!

Anyone else interested in a potential group discount for autohut's 3.0 alpha N software? I'm awaiting a reply to my request for a group discount (3-5 people).

210 euro shipped is already an impressive price, but let's see if they're willing to give us a price break. :devillook

Thanks for taking care of all this Benji.

now...about that subforum for strictly euros...?

please read this...

I received an email from autohut earlier today.

The price is 180 euro shipped per chip set.

I will ask them what forms of payment they accept...

Autohut is charging an additional 4% paypal fee, so the total is 187.20 euro shipped.

Paypal address: info@gsmhut.nl

We need at least 5 chip sets to be purchased to receive the discount so please send paypal payment immediately.

I just sent paypal payment.

Let's get a list going of members who paid:

I received a PM from the mystery member. He's sending payment via bank transfer for 3 chip sets so it looks like we did it. :alright

as above.

ok, so here they are..... sorry for the blurry image (crappy cell phone camera) does anyone know which one is for the vanos computer ?

one says: (I think this one has DME written)

AIRBOX 075

and the other one says: (I think this one has VNC or VHC written)

PS. mods, so no towing to the Euro section ? :(

My guess is that the top chip that says "DME" is for the...DME.

Have they shipped out the chips yet? I'm still waiting for mine.

nothing here either...

Razz...how long did it take for you to get yours?

I received my chips today. :buttrock

I don't want to go too much on this thread but everytime i've encountered CEL on other BMWs, the car seems to go into a 'limpmode'. I know you've shown that the car runs good and that it actually corrected your a/f, but I'm hesitant to try and run full throttle with a CEL on.

I may dyno my car on Thursday, I'll do one run with the maf unplugged just for this thread.

Hi, were you able to do the dyno test and what were the results?

i would like a set please sent to Australia. can someone point me to the right direction?

here is vid of AFR's on the dyno with H&H chips
http://www.youtube.com/watch?v=TqxAnOmr8Y0&feature=user

I have the H&H Alpha N chips from autohut in my car, it still reads IAT sensor, and O2 sensors, as well as predicting fuel and timing based on throttle position and RPM, it also reads engine temp etc, as it is 100% civilised on cold starts etc, I have no hesitation at all in recomending it, drivabilty is as good as stock, with more hp, particularly at top end, on dynojet, I would be ~300whp and can still drive through city traffic at 40mph in 5th gear if I want to

300whp? Wow - do you have your engine specs / dyno outputs?

199.6 rwkw on dyno dynamics, which is somewhere around 300whp on dynojet.
car has carbon plenum, mafless 8000rpm chips, 8.5Lb alloy flywheel, high flow metal cats, X pipe replacing resonator, home made straight through twin 2.5" stainless muffler. enough power to run 12.9 @ 106mph in a 1440kg car with driver at over 1000' altitude on 88* day

should i just send payment or is it to late

should i just send payment or is it to lateIt turns out that I won't be using the alpha N chips I purchased. They are brand new, never used. You can have them for the same 'group buy' price that I paid. If interested, PM me.

were they ever installed

"why Are You Not Using Them"

Are You In The States? Can I Call YouI was planning to do a single vanos conversion on my S50 B32 (ie. Bosch management instead of Siemens) but I've decided against it since Mark D'Sylva will provide me with custom software tuning for my Siemens MSS50 DME.

True.

BTW - my alpha N chips are sold.

To the person who bought them? How does it work?

I just got the carbon plenum from HK, and in the process of installing it in the car. Initally planning on running it still with the MAF...but if the autohut chips are good, why not, they are not that expansive.

i dont know i have not recieved them yet...but i would like to hear about the other people who have them and are using them...

btw EXACC how much waS UR BOX FROM HONK KONG ANY PICS

hrmm.. im after a set for my euro m3 too.. who sells/ships to AUSTRALIA?

If someone is interested in purchasing the alpha n chips from me, shoot me a PM.

Thanks.

I got them for about 3,500 HKD...I was in Hong Kong and found a way to contact the seller directly. He's a nice guy and has lots more CF products for BMWs...will take pics of the set up once it is done.

Mine did not line up directly around the area where it met with the engine...had a guy do some minor fiberglass work on the edges (It would have worked, but I want it to be perfect), and since I have a thick strut bar, I had to add a little bit more resin on it so it angles the entire box so it will clear the strut bar.

Benji, with those Schrick's and a tune from Mark...what would the gain in rwhp be?
BTW, how much do you want for the cams? What does Mark charge for a tune on the dme? Did you just send your dme or did the car have to go on a dyno?

I don't have answers for most of your questions at the moment. Mark was tuning a S50 B32 near him a few months ago but I haven't gotten any update on the gains. He's been very busy lately with contract work. I sent him an email a few days ago and I'm awaiting a response. I'll let you guys know when I know something.

PS - I'm keeping my cams.

Gotcha. I was reading in an older thread that you had discovered that a tune wasn't necessary for the schrick 284's. Is that still correct?

I've been told that a tune is not essential with Schrick 284s and I'm aware of a few 3.0L's running Schricks without a tune but no 3.2L's. Of course, to maximize gains you'll want a tune.
