749 too rich on accel

what table do I start with on the 749 $58b to take out some fuel on accel. ? right now it runs pretty good as for driving but, when I hammer the pedal it smokes so bad I could go back and collect the unburned fuel.


yes, I have a scan tool (tech 1) so I can get decent readings I just need to know where to start. (kinda like the pump shot in my old code?) I see several tables that are for inrichment but, which do I use

ahh there is a table for this.

Accel enrich vs differential TPS and anothe one Accel enrich vs differential MAP.

Id start by zeroijng ou the AE map and then work the TPS table. thee is also a 2d table to limit it via RPM called

Accel enrich multiplier Vs rpm. I use this table to recude my pump shot at higher RPM becuse its not needed as much as at loiwer RPM. then once you ge the TPS differential table ironed out use the AE map differential table to keep the AE comming on during shifts.

thats all i can really offer up for now. i think i did a AE wright up on $58 a while back check the archives and search.

I set everything in the AE tps table to 300 as a starting point, and that got it almost dead on.

You should try that first.
