Throttle delay help

Ive got a $6E bin that I have basically only tuned simple items such as disable egr , and change some spark tables and MAF multiplyers and tables to the 350 tables. The problem lies when I hit the gas wether im moving or idling theirs a bit of a delay maybe 2-3 sec when really mashing on it while idling. After reading some other posts I beleive its in my timing or spark tables but before I change them figure id post about it first any help greatly appreicated thanks

Re: Throttle delay help

Should be your "Acceleration Enrichment" (AE) tables. You can do some experimenting first with "AE (LV8) Mult vs CTemp" table, to see if you can make it better or worse. (may be named differently in your XDF)
Sounds like it's a rich bog, because if it were lean, it'd pop and spit, and probably die. Reduce the multiplier (at warm engine temps) by some (try like 10% at a time), and try again. Repeat until things are better. Best done with a wideband.

Re: Throttle delay help

i noticed in your sig you're running a stealth ram... you may want to do a search on that one. i recall reading in the archives its happened before wheree a 6E will have AE problems w/ that setup.
also i found on my fairly stock setup w/ stock injectors it was very sensitive to the fuel pressure at the rail... i had to mess w/ the FI constant to make it run at operating temp. so i'm guessing with your more modded system, ie Ford injectors, your FI constant may still need some playing around with. Good luck.
