hey all, got the car running with my zzp engine and having some issues with neg idle timing and wierd startups
05 LSJ
Mods:
ZZP Girdled block, 9.5:1 forged pistons, pauter rods, ported head, 82# valvesprings, E85, 80lb/hr injectors, return style fuel system set at 44psi (with vac hose removed), Deatchwerks DW300 Feul pump, TVS with 2.6", header and all catless exhaust, injen intake, cooling mods.
Startup issue: car will crank and start fine but hunts for idle terribly until warm, ETC % goes bananas without touching the pedal. wants to die
Running issues: neg idle timing when in closed loop.
Fueling has not been addressed yet. car has only been started about 10 times, and driven around the block 4 times. The last time around the block prior to this log it wouldnt idle for sh*t and i put a new set of plugs in it. seems to do slightly better.
trying to get it to start and idle correctly before i put it on the dyno.
attached is log showing startup issue and a long drive around the neighborhood, config file (my MAF LTFT+STFT histo isnt working if anyone can advise on that matter), and tune.
ZZP gave me a base file and it works about as well as my other tune i had worked up. the changes i made for the RSFS and some minor other things from my other tune are imported as well.
please give me advice or if anyone wants to take a crack at it i willl try it out.
