ok well my car hates me for the first 10 minutes of drivin till it warms up, and it is areally pain in the ass to drive, but after this warm up pperiod, its pretty consistent so i hooked it up to the wideband and i get all kinds of different idle readings because my idle fluctuates so much, but after I drove for a while and idled it, it was a perfect 12.7 (that is good right) its an enthalpy tune sr. its weird, if i let it idle it sounds good but then when i tap the gas a tiny bit, it will go up to about 15afr and then idle shoots up then slowly goes down and then the af goes back to 12.7, also when i was under no load and creeped it up to 3 grand, the afr stuck at around 15, is that normal. when i was driving, the log was like a roller coaster but it seemed to be in the 14.7-15 range quite often. I dont know what im looking for besides the idle looks good, what numbers should I see during normal driving, is there a difference with load and no load. sorry im a newb at this whole tuning thing.
