 Re: What is going on?
Figured I would reply here instead of in your PM. Without a wideband its hard to say where you are at in all honesty BUT those numbers are definately on the low side and should be around .900mv on the average but it will vary. IIRC you installed the 78mm throttle body and asked me about the maf scaling correct? After getting your fuel trims locked in for normal driving you MUST adjust the table for higher airflow or the car WILL RUN TOOOO LEAN!!!! You must adjust the maf table as now with the larger throttle body the airflow is slower across the sensor which in turn will show the pcm that less air is moving across it and maf signal is the direct link to fueling. If the maf signal is low, the car runs lean. You need to adjust the maf table, watch where to start by taking a scan of the car when heavy in the throttle and start adding from there to the top of the scale until your numbers get to where you want them. |
