Engine management / Re: Does anyone have an M42 175 ECU XDF file they can share?

I am not too sure who did the work on it.

I was looking through the maps that came pre-loaded into it, and they seem a bit all over the place.

I will probably end up paying or maybe going with a Miller MAF conversion if possible.   Sucks to need to turn the car off to update the bin on the ecu with their hardware... RTP is where it at.

Engine management / Does anyone have an M42 175 ECU XDF file they can share?

I am just popping in to see if anyone has a proven to work XDF file for the 175 ECU that I got with my E30 M42 engine.

I got the one from the tunerpro site already. "BMW_175_318i_soft378.xdf"  Can anyone comment on how it performs who has personally used it to run up their engine?

Can't wait to get the M42 swapped into the E21!

Thanks,
Dan

Engine management / Re: MegaSquirt Spark Cut Damaging?

Spark cut can damage things, yes.

When the spark cuts, the injectors are still squirting away.

Once that mixture flows outside of the combustion chamber, it can ignite from the hot exhaust.

This burn takes place half inside the combustion chamber, and half outside, which is VERY hard on your exhaust valves.

You could have burnt up a valve.  Likely?  No.  Possible?  Yes.
