So a buddy and I are working on tuning his car, and he has a TR-6 ignition with the new truck coil.
He was previously getting a little bit of knock on a Turbotweak 6.1 chip for 91 octane and alky injection, and he had the alky turned all the way up and the AFR was pig-rich at 10.8 AFR.
I was wondering if the TR-6 provides such a hotter spark that it can cause detonation if you use the same timing tables as you previously used with the stock ignition system and coilpack?
Has anyone experienced anything like this?
FWIW, we were able to lean the car out and make her faster without detonating, with safe AFRs of 11.4-11.6, but it got me thinking if the TR-6 was providing such a hot spark that we could potentially pull some timing from the table, perhaps a degree or two, and the overall strength of the spark would still be as strong as the stock ignition/coil with the timing not-retarded.
Just a thought. We haven't tried anything like that yet. Figured I would ask here first.
Thanks!
