Help a newbie with idle A/F ratios
Help a newbie with idle A/F ratios
Well, here's the deal. I have a 3.4 DOHC engine (93 grand prix), and I need to adjust the fuel flow at "low pulse widths" i.e. I need to slightly enrich the occasions when the ECM is commanding a low pulse width... for instance, at idle, perhaps deceleration... I don't want the ECM overriding the 13.8 A/F ratio (or whatever it turns out to be) either by subtracting from the integrator or BL... I'm not knowledgeable in this stuff, but I'll pass the info along to a buddy that burns chips for me. Thanks for any help!!

if you don't want it to use the BL corrections i would think you would have to disable closed loop, and run purely off the tables.
one of the smarter peopel here might know some trick to get the BL's to correct to a lower AFR, but that is beyond the scope of my knowledge.
