Lambda readings
Posted: Fri Jul 06, 2007 2:17 pm
I'm running a 3.0 12v in my GTV6. Last summer I ran it with the 2.5 ecu and afm. A while back I came across a BMW 635 ecu and 528 afm. I have a nb-lambda connected directly to a voltmeter but I'm not sure what readings to expect. On WOT I get 0.88 which feels on the safe side 
What I'm more concerned about is the readings I get with less throttle and less load. The volt can go really low like 0.15v when cruising in like 60mph. That feels dangerously lean if I am to trust the reading.
The feeling of the car is great though, it pulls hard from low rpm's all the way to redline. Definately pulls longer than with the 2.5 ecu.
