I need some spark timing info
I got a datalogger so i am reading timing boost AIT rpm , if someone has knowledge about timing advance-retard where i must see the timing? at which gear?rpm? where the safety range must be, how can i know if it is retarding? thanks.

I just datalog and use the info as a reference along with Air Intake Temperatures. This way, you can get an idea of how much timing is being pulled when intake temps/engine temps rise.

You cant determine if timing is being retarded based on the info you gave. It just says you are running 16 degrees of timing WOT at 6000rpm. I'm not sure at what IAT the C32 ECU retards timing. Your ECU will also retard timing if it sees knock

"ECU will also retard timing if it sees knock" - only if the tune allows it to though, right? I've read some alleged reports in the last couple years that some tunes remove/limit some of the ECU's ability to successfully retard enough timing if it senses knock/detonation.

Altitude helps in this case...

I agree. You should contact Jerry. The AFRs look a bit high to me. But I'm not sure how your altitude and the hot Lebanese summer temperatures can effect the C32. Have you looked into something like the KS-3 from Phormula for knock detection?

Robert, when you say -16,the negative value means advanced timing not retard.it means that is igniting 16 degrees before the TDC.your values are great.
