e36 m3 - HELP!!!

biffa wrote: Might be right about the running lean thing.  I had the airflow sensor disconnected (simply unscrew the plug on the box on the rhs of the engine).  It richens everything up and now the problem is virtually gone.  I actually have power below 2500 rpm!!!!! Anyone else with the problem want to try it and let me know what its like.  Don't know what its going to do to the fuel consumption though, but who cares!

Hey Biffa,

That isnt a good idea mate....the airsensor is there for a reason. Also it will show as a fault on the DME now....

Interesting you say it improves it?? I guess the ECU would go to limp mode and use base settings....

I was wondering about documenting this thread and sending it to the tech team at BMW and see what they make of it???

I wonder if it is worth speaking to a chipping company to see if they have done any chips to the 3.0L.....be interesting to find out....thing is who to trust??

As everyone seems to in it for the green stuff these days!!

"Of course sir we will remove all the flat spots give you 20hp more" err that will be £600!

Been running it a couple of day without the sensor connected and it was fine, reconnected it and its running flat again.

Agree with the top end power loss though, and I'm sure it is running too rich up there.  Its quite an interesting dilemma.  you'd think that with a decent air filter, the throttles balanced properly (I drove a 3L that this had just been done on and it was a flying machine) and a chip to remap this apparent fuelling problem, it would be sorted.
