Makes sense thanks Matt im going to up the boost to 11psi and see what it actually hits TP wise, everything is stock.Matt wrote:With factory PSI it wont reach those columns. Assuming that Nissan kept in mind people like to increase the boost in their cars, and it would then take that path (or if the hose disconnected from the actuator and it was running full boost)

Re: Base image S14A vs S15
Timing difference might have something to do with the upgraded ignition coil packs on the S15. The extra timing in the S14 maps probably compensated for the slower response time of the older style coils with the external ignitor chip.
Re: Base image S14A vs S15
Dwell is more responsible for that (ie charge tiime of the coils) where the timing is before top dead when the coil charge is completed (so dwell is done with charge in advance)
From what I know the S15s were more detuned by Nissan, especially ADM models running lower octane fuels here
