Hey guys, Just curious, with all the MAF systems we have sold we were wondering who frequents this forum and has our MAF system. Leave you comments about it if you have one installed. What you like or don't like etc. We will be updating the MAF system soon to make it even more plug and play. Utilizing a plug that will plug into the original AFM plug, thus eliminating 4 of the 5 splices that you have to do!

Not all too many people that have MAFs, but everyone that does, seems to be very happy with it.

Not all too many people that have MAFs, but everyone that does, seems to be very happy with it.Yeah, that's what I've gathered from this. Not too many people have it but many want it. I would like to turbo my baby and I'd look into it. I just don't have money...

I had a MAF system with non-photoshopped dyno gains on my e30.

I put the Miller Maf system in about two weeks ago and love it. Motor pulls stronger and smoother through the power band. A def must.

Thanks for that one stuck, but as we all know it was done for ease of use and our results were proven by a third party now.

Take care buddy.

Many better setups are available on the market to those that desire them. You are the new guys on the block, and are unproven. The only thing we know about you for certain is you posted a badly photoshopped dyno chart.

I posted a dyno of my car after the conversion. I did not have the time or resources to do it pre-conversion, but it is a dyno graph none the less.

Concerning the MAF conversion, not many people have done it. I have started researching Megasquirt as much as I can because I desire to go turbo in the future.

EDIT: Also, still waiting to see updates on the M30 turbo system.

Not trying to be an ass, but I don't know about "the many better setups that are available", especially for an E30. I've looked for about two years for a reasonably priced system that was better than stock, but couldn't find one. My mechanic, who is a Turner Motorsports Race Mech., actually recommended this system. So far, I am very impressed, especially over the Turner Chip.

As far as unproven. I don't know about that comment either. You may not have heard of them, but check out the many other E30 websites. There are a lot of happy customers around. And since I put one in my M3, I'm one of them.

Lastly, I will dyno my car as soon as I can again and post the results. I did a dyno about 2 weeks before the MAF and I'm curious on the actual results on paper now.

Thanks Mscott, We will be out in Charlotte on Friday of this week. If you need anything else just contact me and I can help. Otherwise thanks for the positive input.

there aren't that many MAF conversion kits available and having to use a piggback is an extra cost that many don't want.

post it up!
I am intersested to see a before and after of MAF only swap (i.e. only the MAF was changed nothing else not even an air filter or spark plug) obviously tuned to suit though

You probally wouldn't see any gains except for throttle response doing just a MAF conversion on a stock car.

Do you make a MAF for a M30 engine??? How much $$?

Yes we do! its 489.00 US and you can see it here....http://www.millerperformancecars.com/m30maf.html
This is for E34 E32, and the E28 E23 MAF is soon to come.

As for the gains that someone mentioned, your right, the gains don't come from just the MAF. You need to tune the car to run on the MAF. The chip provided with the System takes care of all that. No need fo you to figure out tuning. The MAF SYSTEM gives you more power but even more torque and midrange than a performance chip chip alone and like mentioned way better throttle response.

I doubt I'm the only one who likes the idea of this MAF upgrade, but isn't getting one until some comparison is done to a chip, like a JC or EAT.

To put it bluntly, I'm not about to spend 500 bucks for the same gains as 250 gets me (or less, since chips aren't too hard to find used) and is mutually exclusive.

Definitely something I would look into if I see some solid comparisons.

I have the Miller setup on my M3. I know most people want a system like this for the torque and power gains, but in my opinion that is not what this kit is really about. Now don't get me wrong-there is a noticeable increase in torque and the car definitely pulls stronger, but the big improvement is in the driveability. Some of you may think, 'Big deal'-well it IS a big deal-especially on an E30 M3.

My car has gone from being one that was tiring to drive around town due to the poor throttle response, lugging off the line, and lack of torque-but with the Miller kit, all of that is a thing of the past. The car starts quicker, idles smoother, responds to accelerator changes quicker, the ability to have smoother shifts, etc.-I think you get the point. No, they ain't paying me to say this-I paid them almost $600 total for my kit, and I am very satisfied and would do it again. To top it off, Dan and Brody are very helpful and their service after the sale is excellent.

The kit has made my car much more enjoyable to drive-the power delivery feels more 'refined'-smoother with none of the flats spots you get with the AFM. Let me give one more example-drive around town in your E30 with the A/C on-notice how when you slightly get on and off the throttle the car bucks a bit due to the load on the engine? Makes it hard to drive smoothly at low speeds. Well, with the Miller kit that is gone. It's the little things like that it changes that make such a nice difference.

:eyecrazy Are you trying to sway my decision? I'll probably really look into this more after the new connectors are available.

The new connectors will definitely be a big plus-not only for the ease of install, but especially for E30 M3 owners. When we change our oil, we have to remove the airbox assembly so that we can access the oil filter. The current connectors are of decent quality, but I don't think they would last with all of the unplugging/plugging that we would have to do. When I was talking to Dan on the phone a week or so ago, I mentioned this to him and he acknowledged they were developing a connector for the factory harness.

Maybe when the connectors are ready they will send me one? Hint, hint! ;)

Not sure I could find it now, but there have been one straight Conforti chip dyno. The one that I saw showed 180rwhp and 200rwtq, for a M30B35. I don't know what kind of dyno, what conditions, any of that. But, given clever's results, it certainly swayed me. I know the S38 guys were seeing slightly more than 20rwhp just from switching to a MAF from an AFM, and that was using a piggyback.

I bought one for my CS. I haven't installed it yet, since I have been at university, but during spring break, that is one of the many tasks to accomplish.

Brody- any chance you guys could make a catalog entry for the plug? I would very much like one, but I'd need it fast. Congrats on getting the supporting vendor status verified.

I decided in late 2004 to go with a standalone Autronic SM2 DME on my dd E28 M5. The cost in the end was $2850 and that was on the cheap side because I did the install and the Autronic has a nice auto-tune system that greatly reduced tuning time/cost.

If the Miller system had been available at the time I was looking to ditch the AFM, I would have bought it in an instant. However, my other E28 M5 will be receiving the Miller treatment.

I can echo Eric's statements about the driveability improvements to be gained by getting rid of the AFM. I think I gained over 24hp from the Autronic DME (dont have teh dyno sheet on hand), but the improvements made in so many areas are worth the money. The Dinan chip with the AFM? Thats garbage compared to the updated engine management system a MAF can provide. The engine has so much more breathing room, it revs so smooth and drops revs much easier. Gas mileage has improved, and the engine doesnt dump a lot of gas at low speeds, so the plugs are not fouled up. The idle is unbelieveable, the engine is really transformed with the new DME.

From what I have heard from people who have used the Miller system, its an easy system to install, its far safer for the engine than the SplitSecond stuff, and the cost is really competitive. It costs more than a chip, but you get a lot more than just an EPROM chip with some new maps on it.

Thanks Mscott, We will be out in Charlotte on Friday of this week. If you need anything else just contact me and I can help. Otherwise thanks for the positive input.

Going to be down at Eurowerks again?

Going to be down at Eurowerks again?

Yes we will be. It will be just Dan this time as we are too busy here for both of us to leave. But he gets in thursday night and will be there until monday morning.

If you want any custom tuning done let me know, I think you car is stock though? If so not needed.

Yep, stock. Interested in meeting you guys someday, but I think I'll be out of town again this weekend.

Brody or Dan, 2 quick questions. I didnt want to clog up your inbox.

Has anyone used the MAF inconjunction with the M-Fs intake manifold on a N/A motor and if yes what were the combined gains?

The literature seems to suggest you can use the MAF with forced induction, but even your own turbo kits uses a MAP sensor instead. Do you mean that your chip is reprogrammeable and you can re-use that (not the MAF) or do you mean something else?

To put it bluntly, I'm not about to spend 500 bucks for the same gains as 250 gets me (or less, since chips aren't too hard to find used) and is mutually exclusive.


No back to back comparisons, but my chipped 535i (otherwise stock) made 180/195. The same day I dynoed a friend had his 535i that was stock except for a Split Second MAF and he made 195/210? I can't remember the exact torque number, but it was well over 200.

You just don't see chipped cars getting much over 185rwhp. I realize comparing different cars is somewhat less reliable, but it appears that a MAF kit is worth something like 15hp and 10ft-lbs more than just a chip.

That makes sense, when you consider how restrictive the AFM is.

Thanks. I like numbers. Still not a true comparison (and using a different MAF), but much better.

Ah, good, my numbers were not misleading, then.

I just wanted to chime in by saying that the guys looking at this type of thing in terms of more power are the same guys who PM me asking if a standalone on an NA car will provide more power. The answer is YES, it WILL get more power out of your engine if you TUNE FOR IT. Basically, you have to have supporting hardware and on an NA motor that means a lot of dyno time to get it just right with peak gains. I just wanted to make sure people understand that sticking a different meter on your induction system isn't going to make a huge difference right off the bat. It's less of an obstruction as far as air flow is concerned, true, but its still just a metering system - the same air passes through it as it does the AFM.

For you guys interested in both this and a turbo kit, I'd really recommend you not do a MAF setup. Most standalones cater to MAP based systems, not MAF - MAF provides a good method of metering for driveability but honestly MAF is not the end-all-be-all for forced induction, so just keep that in mind.

I'd recommend EVERYONE who wants to maximize driveability to consider a MAF conversion, but do not expect to pick up 20hp and 30tq from said device.

Two of my 535is dynoed 170rwhp stock.

MAF cars are making roughly 25rwhp more than that, so I think picking up 20hp is on the low side.

Did I read the application right, this MAF conversion won't work on an 89 525i, m20?

Deleting the AFM is the best way to really get power, reponse and performance out of our cars. I' ve a Maxx Automotive Alpha N and I m really pleased with it :) .

Is this system installed on your M3? Did you have to do any tuning? How is drivability? Also Im guessing that its some sort of Piggyback system, Does it change timming or just Fuel? Just Curious as to how it works and why you like it.
