Re: APV & VDI settings

I settled at stock APV, left VDI at 7400. The drop off in torque by increasing the APV RPM setting seemed to be of zero benefit.

APV & VDI settings

Just wondering if anybody has played around with tweaking these? I know VersaTuner tunes changed them from stock, but what's optimal on a healthy engine and tune?

Re: RX8 ignition dwell

I switched to the above coil dwell times (the lower half of that image) with a huge improvement in drivability & throttle response and the car definitely pulls stronger too.

Re: RX8 ignition dwell

Thoughts on using the "typical" D585 dwell times? VersaTuner caps the dwell time at 10ms, but honestly I can't see any reason to *need* the higher dwell at those crazy low voltages anyway. https://www.rx8club.com/attachments/series-i-engine-tuning-forum-63/187291d1342848174-coil-dwell-sett...
