View Full Version : Best N/A Tuning software?
dzlnitro 01-15-2008, 11:11 PM My friend currently has DA race software, and his mods are streamline drop in panel filter, dixsis exhaust, borla midpipe version 1, evosport headers, no cats.
He currently isnt satisfied with the software.
I recommended AA tuning, i've read they are reliable and do a great tune. I cant vouch cause well I dont own a e46 m3....yet.
So he is considering AA tuning or Evosport software. He wants the most aggressive tune available. Upside, is if the evosport is better, he gets a free tune because he purchased the evosport headers.
He would purchase cams if they do make a substantial difference. He's not afraid to spend the $$$. He isnt ready for FI yet though.
Also what is the most aggressive set up possible with these. If you could provide any HP/TQ figures as well that would be helpful as well.
egyptntree 01-16-2008, 01:54 AM AA is definitely not worth his money. I had AA, shark injector, and D/A. The D/A was definitely the best. I don't know if he will be able to find anything more aggressive without actually putting the car on the dyno and having someone tune it that way. I think all off the shelf tunes are pretty standard with just minor differences.
OxfordM3 01-16-2008, 02:01 AM I would go with D/A.....AA's customer service has been less than helpful every time I have called....seems like I am not the only one experiencing this if you run a search.
Ingenere 01-16-2008, 03:22 AM Veloce Performance has a great M3 ECU tune.
dzlnitro 01-16-2008, 02:42 PM Has anyone here used veloce and can vouch for them?
mpower001 01-16-2008, 04:33 PM Has anyone here used veloce and can vouch for them?
Never heard of Veloce. Do they have any dyno sheets to prove gains?
I cant tell you that D/A is the best for the E46 M!! I ran a car that has similar set up but with Shark injector and I pulled on him. I picked up 19rwhp which is very reasonable gain for headers and software!! Good luck!
Ingenere 01-17-2008, 01:56 AM Has anyone here used veloce and can vouch for them?
I own the company and none of our M3 clients have complained. I have done the development work on the tune over the past 3 years, and at the track I have no problem hanging with 997 S's on the straights. Based on my car and our client's responses, I know that we are on the right track.

Based on my car and our client's responses, I know that we are on the right track.
Post up some dyno sheets...
I would prefer to use someone who is actually tuning the fuel/ignition/vanos and not just remapping the throttle to make the car seem faster. Not that these bigger companies are not tuning the rest of the stuff, but they are staying on the safe side and some of us want to be as aggressive as possible.
that being said.. I went ahead and installed a new piggyback engine management system that gives me full control of ignition and fuel independent of eachother and without having to trick the computer, however I cant tune vanos...
Even still, with full bolt on mods I am making 321 RWHP and 263 RWTQ... My car has gotten very very fast...:D
Our cars suffer around an 18-19% drivetrain loss so that would put me at around 400 BHP and 321 TQ (crank numbers). We also pulled a bunch of fuel out during steady state tuning and if I cruise control at 70 MPH on the highway I can get just under 600 miles per tank. but 70mph on a long distance trip is slower than hell to me... I think we have a 16 gallon tank so thats almost 38MPG...:D
A STG 1 AA SC is rated at 480 BHP which should come out to around 388 RWHP making it only 65 RWHP faster than me. and $9,400 + install ($1000)...
I do however, need to find someone who can tune vanos so that i can see what kind of numbers I can make with vanos tuning.

Piggyback systems are great, but definitely not for everyone. We work with the fuel and timing, as well as a number of other parameters. On US cars we are ~365hp at the crank, which is a nice bump...but not 400. Because of our client base and from a "keep it together" side, we can't be extreme. Also, there are limits as to what one can do with the stock ECU.
We don't just remap the throttle to make the car 'seem' faster. Anyway, the piggyback system that you are using sounds like it is working out well for you.
mproved 01-17-2008, 04:24 PM Do you mean to tell me that your Veloce software tunning alone will make 365hp to the crank? If so, that's really good!
dzlnitro 01-17-2008, 07:05 PM 365 w/ what though? intake,header,exhaust?
bemve 01-18-2008, 12:10 AM 365 without any other bolt-ons is pretty good. I've never seen those numbers before though.
What is it that your friend is not happy about in regards to the DA Software?
ohnoes 01-18-2008, 12:20 AM I have D/A Race. While I have not compared it to stock (bought with the software installed), it seems to pull extremely hard at high RPMs. Low-end torque on these engines is less than impressive, but then again it is a strung-out DOHC six, not a pushrod V8.
HiRide 01-18-2008, 12:34 AM Yeah, the 400 is with bolt on mods though... not stock motor and stuff. So 365 on a stock motor with no mods is pretty stout. I would probably prefer your tune to the bigger names as they tend to do alot more throttle mapping.
Personally I wouldnt mind some throttle mapping and vanos mapping on top of my piggyback tune. Yeah the piggyback isnt for everyone and its very expensive for the gains on an M3 especially when you add dyno tuning time.
I would like to talk to you about using your ability to tune other parameters that I cant touch on top of the piggyback. the nice thing is that I can real time tune the fuel and ignition and that would be nice for the vanos as well, but I would love see what some vanos tuning through the DME will do to my numbers across the board.
The big reason why i went with a piggyback was to begin my turbo project. I am currently working with another group that is doing a DME only turbo project, but we are just sharing information and support as opposed to developing together. I dont know if I will get the same kinds of deals from their resources so I am still looking for my own.
with this piggyback and its internal MAP sensor I can tune a turbo on the E46 M3 no problem... but I need to custom fab turbo and intake manifolds which is costly for design + fab. other than that, I really feel that BMW power is unlocked through VANOS, and being a vanos junkie its kind of ironic that I cant tune it with my setup...:D
Either way, the $1600 I spent on my tuning is way too much for someone looking for just an NA tune, but its worth it when it gives you the ability to build your own turbo setup on an e46 M3. I do believe that if the DME only team cant find a way to tune or make at least 400-450 RWHP they will probably want to go with the piggyback. I mean with this thing I can add extra fuel for a nitrous kit (dry into wet with fuel from the injectors), add methanol injection, built in boost controller, launch control, shift light, intercooler spray, etc...
honestly I am also looking to employ this setup on SC cars so they can run race fuel tunes, meth injection, nitrous, etc.. and have it all controlled by one unit . Also, I think you can make bigger numbers on the usual kits just by re-tuning in real time.

One of our distributors (Extreme Motorsports SD) over in San Diego is putting together turbo kits for the M3. We are doing the ECU set ups for them. You may want to check them out...they are on our partners page. Speak with Kurt, he is a great guy and he knows his stuff
I love our NA set up. At the track I surprise allot of heavy metal on the straights...and then I run away in the corners! :)
HiRide 01-18-2008, 02:59 AM very nice..
I checked out the site, but the SD site is very difficult to navigate. the colors of the links are the same as the background. I did see the projects in which you will be the tuner. Sounds very cool.
My only question with all these people trying to do DME turbo's... how do you plan on tuning them. As of right now no one has the ability to crack directly into the MSS54's tuning tables and allow real-time tuning of fuel, ignition, and vanos. And vanos doesnt really need to be real time, but the fuel and ignition do.
I guess you would have to switch to a blow-through MAF to get a proper reading and one that goes over 5v so you dont hit fuel cut. But even then, the most you can do is tweak the tune and let the MAF do the rest. AA seems to have it working well on their obdII e36 setups, but they have also chosen not to go that route with the e46 M3...?
It just seems like a lot of extra work to use the DME when you are going to have to wire a boost controller unit and a turbo timer anyway. I dont have anything against building it, I guess I just dont understand why so many people "need" to have it running on the DME only.
I just wish I had the money to get all these parts built and be done with it. The sad part is that I can tune my car for a turbo tomorrow. but i cant build the manifolds. Everyone else has fabricators designing parts right now, but dont have concrete tuning.
oh well...
1TiagM3 01-19-2008, 12:03 AM I never saw any dyno sheets, all I think i read was a 33hp gain...can you provide dyno sheets to back it up?
Yes 33hp is a substantial gain from ECU tuning alone. I don't think anyone has seen anywhere near that with just software? Dyno sheets would be beneficial for comparison to software such as DA, AA, Conforti etc.
konfoo 01-21-2008, 01:03 AM I would also like to see the dyno sheets. I am running with Dinan s/w and not too happy.
HiRide 01-21-2008, 01:04 AM Dinan is crap...
1TiagM3 01-24-2008, 12:01 AM Bump for dyno sheets of a Veloce tune.
McoupeBobby 01-24-2008, 03:12 AM VERY intrested as well.
I just purchased an e46m3 and an ready to mod...
dyno?
edit:wow 900 for a tune. that is prety damn pricey...
definately need a dyno to back that up if your gona charge that much.

Well we just finished like evolution 10 of the Powerchip/evosport tune for the S54. I was amazed when I got my car back. I would put MONEY that no tune is better as far as feel and dyno. Seriously - anyone what to challenge, we can arrange a dyno day. Same car, same dyno, same day.
Best thing is that Powerchip gives you a 30 day money back guarantee!
I would go with D/A.....AA's customer service has been less than helpful every time I have called....seems like I am not the only one experiencing this if you run a search.
FYI, he said he already had D/A and "currently isnt satisfied with the software."
Veloce Performance has a great M3 ECU tune.Never heard of "veloce" except when I started and trademaked that name for Automotive use in 1998. :stickoutt Happy to sell you the trademark! Actually my company was "Veloce Imports" not "Veloce Performance" - so safe to say I like the name!
I cant tell you that D/A is the best for the E46 M!! I ran a car that has similar set up but with Shark injector and I pulled on him. I picked up 19rwhp which is very reasonable gain for headers and software!! Good luck!
D/A = Conforti, FYI. D/A used to sell software from Powerchip (that was the same software that we sold and developed on our dyno - YES, the D/A race used to = evosport/powerchip). Now it is done by Jim Conforti for D/A.
I own the company and none of our M3 clients have complained. I have done the development work on the tune over the past 3 years, and at the track I have no problem hanging with 997 S's on the straights.

Brad
Well I would have to say yes, Conforti does do some work with them but the program is not the same as the Race Shark Injector. Race Shark is pretty off the shelf. D/A tunes your car according to what mods you have. Shadowman over at D/A had his own codes before Conforti joined the D/A team.
HiRide 01-24-2008, 10:20 PM Well I would have to say yes, Conforti does do some work with them but the program is not the same as the Race Shark Injector. Race Shark is pretty off the shelf. D/A tunes your car according to what mods you have. Shadowman over at D/A had his own codes before Conforti joined the D/A team.
D/A's software IS off the shelf. they have a tune for each mod setup on a shelf. I mean there are like 5 different version of the Shark for the E46 M3 as well. just like D/A has different tunes for different setups.
You have intake... they have the intake tune
you have intake, headers, high flow cats, exhaust... they get the intake, headers, high flow cats tune...
So while they do a lot of different tunes for different setups, they are still standard tunes, not custom at all.
Custom refers to specifically tuned for YOUR car. In other words, If i put my tune on your car, you would not get anywhere near the same results. And in actuality no tune will be the same on two cars but there is a difference in making a tune that will work on most cars and making a tune designed for ONE car only.
none of the DME flashes are custom... they are all shelf tunes designed to be the most effective while staying the most reliable on as many cars in as many conditions as possible. And there is nothing wrong with that, that is just how it has to be if you are going to sell a tune.
McoupeBobby 01-25-2008, 05:57 AM so it seems like d/a, AA, and shark are pretymuch the same damn thing rite?
what are the different prices?
Brad @ evosport 01-25-2008, 10:26 AM AA is different then the D/A/Conforti.
But you should look at our option. Seriosuly, how can you go wrong with a 30 day money back guarantee? $640 for the tune, and you get lifetime updates just for a re-flash fee. So if you upgrade the car, you don't have to BUY software again over and over.
thanks

that sounds great but conforti does the same thing for 500 with lifetime updates for a re-flash fee of 100. I guess depending on what your reflash fee is. Im either going to go with you or shark.
McoupeBobby 01-26-2008, 04:10 AM i just contacted HPF to see if they do NA tuning, they do anddd they also tune the vanos tuning unlike any tuner out there. but just guess howmuch there software costs. If your right within a thousand ill give you kudos... haha

So you bought a car that you claim is supposedly slower than the S52 M coupe you used to have? Interesting. Congrats though.
McoupeBobby 01-26-2008, 03:38 PM So you bought a car that you claim is supposedly slower than the S52 M coupe you used to have? Interesting. Congrats though.
my mcoupe was definately faster and I loved it more but I wanted to try something different so I got the m3. is that so wrong? NO its not, so if you dont have anything usefull to contribute in this thread then GTFO now.

ouch a few typos and suddenly i dont know how to spell :rolleyes.
and watch the cute comments "try not to wreck this one" im not trying to start a war but a little respect goes a long way buddy. I would expect someone that has been on this board for a while to know that, I guess not?
anyway, this is not what the forums are for. If you have some sort of a quarrel with me then please shoot me a pm so we can keep the forums clean of this kind of crap.
HiRide 01-27-2008, 05:38 AM Yeah... AA is completely different than D/A and the Shark is just not comparable to either of those. Powerchip from Evosport is different from all of them and is comparable to D/A Race and AA which will give you a tune for your mods as well.
HPF sells their piggyback system alone with an N/A tune for $5000 I believe and gains about 35 RWHP peak, with an average of about 15-25 RWHP gain over the rest of the curve. Actually some pretty good numbers. But they also said that it makes the check engine light come on..? So you would have to either deal with the light or just use it for track days. I dont really see the point in spending that much money for something that leaves your SES light on.

UNLIKE any tuner out there?
I won't speak for my friend Brad, but allow me to interject a correction on
behalf of myself and anyone I tune for.
For the E46 M3 we tune (and this is a summary, not exhaustive list).
Air fuel ratios
Ignition timing
Knock control
Electronic Throttles - and I don't just mean "the feel of it".
Intake cam positions
Exhaust cam positions (that's vanos guys)
and then we get into the good stuff - which I shall only :D about.
(except to say - did you know that there are intentional electronic
hp, trq, and other limits in the ecu? limits besides "speed" and "rev" :devillook )
Having the source code does of course make for somewhat of an unfair advantage :redspot
I'm not sure what the denigration of the Shark Injector is all about, but for
an in the box tune - making +10rwhp at peak and nearly +23hp max gain
near the redline - same car - same dyno - same FUEL - and I wasn't even
PRESENT at the dyno - well, I can't complain. A fluke? Hardly - a second
M3 at the same dyno produced +17whp gain at peak, and a peak gain of
over +27whp.
The D/A tunes are specific to D/A for specific sets of mods. The Shark Injector
was designed for a "stock" M3. Different beasts.
The D/A tunes combine the synergy of Bill's knowledge of hardware with my
knowledge of the MSS54 ECU software. IMHO, a good combo.
What others, however, have written is correct in full - they are ALL out of
the box tunes - if you want the last HP you need to be custom tuned.
Come see me at Bimmerfest and we can talk about that. :cool
Jim
PS: The Shark Injector is updated for free anytime BMW updates your car.
With the new USB port design coming - soon you can do it yourself!

I won't speak for my friend Brad, but allow me to interject a correction on
behalf of myself and anyone I tune for.
For the E46 M3 we tune (and this is a summary, not exhaustive list).
Air fuel ratios
Ignition timing
Knock control
Electronic Throttles - and I don't just mean "the feel of it".
Intake cam positions
Exhaust cam positions (that's vanos guys)
and then we get into the good stuff - which I shall only :D about.
(except to say - did you know that there are intentional electronic
hp, trq, and other limits in the ecu? limits besides "speed" and "rev" :devillook )
Having the source code does of course make for somewhat of an unfair advantage :redspot
I'm not sure what the denigration of the Shark Injector is all about, but for
an in the box tune - making +10rwhp at peak and nearly +23hp max gain
near the redline - same car - same dyno - same FUEL - and I wasn't even
PRESENT at the dyno - well, I can't complain. A fluke? Hardly - a second
M3 at the same dyno produced +17whp gain at peak, and a peak gain of
over +27whp.
The D/A tunes are specific to D/A for specific sets of mods. The Shark Injector
was designed for a "stock" M3. Different beasts.
The D/A tunes combine the synergy of Bill's knowledge of hardware with my
knowledge of the MSS54 ECU software. IMHO, a good combo.
What others, however, have written is correct in full - they are ALL out of
the box tunes - if you want the last HP you need to be custom tuned.
Come see me at Bimmerfest and we can talk about that. :cool
Jim
PS: The Shark Injector is updated for free anytime BMW updates your car.
With the new USB port design coming - soon you can do it yourself!
Thanks for your input Jim!!:buttrock
I didn't mean anything negative when I said it was off the shelf, just trying to explain that it is for a stock vehical. Looking forward to chat with you at Bimmerfest. Hope the Roadster is working out for you.
HiRide 01-31-2008, 03:21 AM So I have a question, if Jim comes back...
with all that access into the DME, why is it still impossible to build a turbo setup that runs off the MAF and is tuned correctly in the DME?
It is being done with the OBDII e36 M3's, although I think they have to redirect blow-off back into the charge to keep the MAF from cutting fuel completely. But it can be done and makes decent power. I dont see why that wont work on an E46, the MAF seems to work fine with FI and doesnt max out, unless tuners are doing something within the DME to keep the MAF from cutting fuel.
Also, I dont doubt that Jim can create some monster power with a custom tune and has access to every corner of the DME, but that is not the same as the standard D/A Race software package. Not everyone can go for a custom Jim Conforti tune...
Well, hopefully the DME editor gets finished so that we can actually tune for our own car.
