FD RX7 Timing Map
The main question I have is what is too much advance timing to where it becomes obviously dangerous? I'm running an FD 13b stock twin turbos non sequential, with Street port and Goopy Apex seals. Large SMIC intercooler with intake temps that peak at about 115 degrees F when ambient temps are approx 85 F. Pushing over 300whp at 11-12 psi.
Timing map 1 shows much more advance timing from 2500rpm to 5000rpm than timing map 2, the car builds boost on timing map 1 so much quicker(full boost @ 3800rpm) than the later timing map 2 which hits peak boost @ 5000rpm. Is the timing map 1 unsafe for my application? Should I be concerned with timing map 1, I've compared it to several other maps I've found online, including adaptronics basemap. But I understand timing plays a large role and varies depending on setup.
I also need about 15 degrees advance at idle to keep the motor running smoothly @ an AFR of 13.0.
