Need help tuning: Acceleration enrichment question
setup: sr20ve, rt calum ecu, nistune software, o2 sensor feedback off

several conditions, however here is one for example: while driving on the freeway in 5th gear, i press on the gas and there is a slight hesitation. as it turns out on the wideband it goes from say 14.7 to 16.5, then finally to say 13.3. is that related to the timing maps, or is there some kind of acceleration adjustment i could make somewhere? my fuel maps are set so i'm ruling out that variable. any suggestions? hmm, come to think about it maybe i'll try to increase the fuel pressure and drop the kconst...

stock sr20ve setup i was using your cjjve bin file and all was fine. i just recently swapped over to a ASP budget header and instantly had to change the kconst from your originaly setting of 274 to 304 to get the idle and light load around stoich. then had to really add fuel to the last columns since with the header it ran really lean.

which adr file are you using? the b14 one i'm using doesn't have one specific to accel enrichment. i believe Matt wasn't sure on the address for the b14 applications so if you happen to know it hopefully you don't mind sharing it.
