e36 m3 maf how to make it work

[persianbmw]

anyone know how to make a maf sensor work on an e36 318i any links my cars stuck need some advice detailed diy not jsut that you need a tune

Youll need a reducer, due to the different sizes, likely the wiring is completely different, the tuning is different, and if you get it to work, the CEL will come on and go to default mapping, thus rendering it useless. If it does plug in, there wont be any gains from it and it might not produce the correct dynamics for the DME to properly produce ignition and fuel mapping based on teh air flow and density.

From all the data I've read, and the engines I've played with there is no way on a normally aspirated engine its worth doing the swap, that fancy little Bosche door just does not impact air flow much. Everyone I've run across who actually dynoed before and after was unable to prove it helped to switch from meter to MAF. (Assuming thats what your doing)

Now on a turbo engine or a really high strung Individual throttle body motor, you can find a couple HP. or a Real high volume turbo motor...

He is turbo. M42 and stated he can't fit the old style in but can fit in a M3 MAF.

Anyone know how to convert M3 MAF or does he just use the M44 MAF?

I have no clue on this and no tuning to help him

Posting actual information, rather than a vague "will this work" will yield much better results. Go on the E30 sites and forum on bf.c and see what they run. Also, doesnt NickG have mafs or something for the larger conversion when overboosting the Dasc?

I don't think Nick tunes OBDI chips. He just drops in a M3 MAF and changes the tables in the OBDII HEX. This car is OBDI old style flapper door MAF and he wants to convert to Hot Film MAF

You got any pictures to post. I heard they had to cut your frame too?

I'm interested to see the final product. Can you get under it with a camera when it's on the lift and all angles on top?

Thanks, John S
