this Sunday me and Brian are taking my car to the track to do a test and tune day, all dynos are booked till the end of July and August is too hot to run the car.
car has trouble getting to 4200 and building boost without nitrous,
2g auto - basic mods list
transmission - shift kit - forced 4 100.1 tcu - kiggly upgraded 3 gear clutches, 4200 stall precision converter,
engine 7 bolt - (bottom) wiseco hd 9.5:1, howard 1 beam rods, (head 1g) +1 int +1exh, gsc 288 cams, late 1g cam sensor, no crank sensor
bolt on's - borgwarner 75/74mm turbo 105lbs, 2250cc inj, mechanical fuel pump, arc 2 ignition box cop set up, 75 shot nitrous, ecmlink v3 full
- my tuning set up now for nitrous.
button 1. on steering wheel, to activate idle switch and nitrous solenoid at the same time. which activates secondary fuel adjustments for deadtime of +1215 usecs. to keep a/f in check
button 2. on steering wheel, activates arc 2 ignition box for a launch limit of 4000
ecmlink. using antilag for timing retard for nitrous and spool 3850prm-4000rpm (this does work but it takes some time to spool the turbo - this is why i need help with my timing map, for an assist )
questions
1. what should my timing map look like from idle to launch limit of 4,000 rpm to help get up on the converter and spool (10-12psi) (more timing or less) im seeing both ways everywhere i look.
lets pretend i dont have nitrous, what would help my get up closer to that 4k mark, i know that my turbo will not spool up with out nitrous, but im asking what a good all around method.
2. is someone available to help me on Sunday (6-26-22) if i send logs to help dial in the timing map for launch only
