So many better things I could do for $595

Gunni - I have combo'd the Perfect Power unit with my M106 Turbo installs and they are a good combo. There, you get what you are talking about - full control over the fuel/timng maps via simple Windows software running on your laptop computer while the car is running. I sell custom implementations of this on my web site as a "Tuning Kit". The maf upgrade is not intended to be a tuning kit, as I have already done the tuning for the m42. It is simply intended to be a replacement for the old fashioned barn door.

Alpine003 - You're right. You do need to know a little bit about binary programming. Tee hee!

e9nine - Yes, you'll get more power. No doubt about it. But surely the power gains are not dramatic. 5-10 hp gains on a 130hp motor is not going to rock the world. Still, it is welcomed!

e30own'er - I'd have to custom tune your car in person, on a dyno.

bmwman91 - I did read your Maf kit exploits on the elctrical board. I hadn't seen it prior to posting my maf kit thing. Mine was done just because I produce these for other BMW motors and having fallen in love with my m42, I wanted to make one for it. I have a very good handle on the velocity curve design for the sensor housing based on my experience. And I have 2 CNC machines in our shop to make MAF housings and other parts. I will say only this: the velocity stack shape and size is very important! :-)

Euro Nation - you are definately right. If your current AFM is in top shape, you will not be well served to plop in an MAF kit. Although I have to admit, it looks great though, in the engine compartment!

Now I just need to clean up the rest of my engine compartment to match the looks of this new machined part. :-)

If anyone is interested in a combo kit combining the MAF housing and Perfect Power piggyback controller, let me know. I have a good handle on making those things work really well. I didn't do it for my M42 because it is all stock and I do not see myself needing laptop tuning control. However I have this setup on my M88-powered M5 and also on my old 83 745i and it is great.

This is a great board. Lots of good stuff.

My next project is to pull the entire suspention and brakes off the wrecked e30 M3 I have and put it all on my 318iC. Should be great as my shocks are totally gone on the 318. I am bouncing up and down all the way to/from work. I'll keep you posted!!

Happy new year.

Oh man, what I would give to have some CNC milling centers.......

Yes, velocity stack design is very important! Sounds like you have some pretty good tools at your disposal.

hey, i purchased the conversion a short while ago...i know you guys are shipping these out mid-march.

i forgot to ask, what kind of fuel and rev limit will the chip have? can i specify what i would like?

I'm no mechanic, so I need to ask this really dumb question.

Am I able to just throw this in my all stock 318 and go? Or do I have to do a bunch of other weird stuff like do some sort of rewiring or coding? If I can just throw-and-go, I'm definately interested.

yes it is!

Ordered mine today! Can't wait to get it.

I just want to give everyone an update on the Miller MAF kit. As you probably know, my car is the M42 test bed for the MAF kit. I haven't had time to really get into the little issues we've been having with programming.

I have been really busy the past six months because my mom has been very ill. (She has made a tremendous come back and it now in rehab!) I apologize to everyone who has been waiting, waiting, waiting for the MAF kit.

I'm still overloaded and very little time to play with the M42. I'm giving my car to Dan for a few weeks because he's coming to the lower 48 for an extended drive to work on some customer's cars. We'll hook up the computer and monitoring equipment inside my 318 for his trip (over 1500 miles) so he can monitor engine functions while he takes his long journey. This should give him time to solve the drivability issues we've been having with the motronic programming.

More news to follow in 2 weeks or so. (I return from visiting with my mom around June 9th, my birthday.)

damn its too bad. I thought i was gona get a free one until his trip cause him to use your car instead of mine:(.

with 595$ , you can get a complete wiring kit , ecu and Maf from the M44 engine and use it on the M42 engine , my best friend did it on his M42 E36 , and works just fine , without ecu reprograming , dyno and stuff... just changed engine wiring , ecu and afm , with the one he got from a M44 engine...the only thing that does not work is Knock sensor that M44 has , and M42 have not..but still you can put Knock sensors to M42 block and make it work...

What system? That would be the first piggy back style MAF conversion which work without difficulties. Piggy pack (or ECU as you wrote) just converts MAF volt readings to DME in the same level as original AFM does. I don't know such a system available for BMW E30's but for example Porsche 944 S2 uses this system:

so, are there any updates on this unit? Have any of you who stated above that you purchased - have you received it and if so, how did it work out??

Can you explain a little further about your above statement? Did your friend use a complete M44 engine wiring harness - or was there a certain harness that was swapped out - or did a harness have to be added/soldered into the existing M42 harness? Please explain more.

Ok after reading it more carefully this is how i understand it:

Take M44 ECU & MAF with complete M44 engine wiring harness.

Remove your original M42 AFM, engine wiringharness and ECU.

Install the stuff you took from M44 to your M42.

All other componets can be bolt on except the knock sensor. Did i got it right?

I am still a little bit skeptical about how does M44 ECU work with M42 engine, after all M44 is 2.0 liter engine.
