engine/air temp and ignition
 

Hey guys, need some help. I am tuning my car myself since there are no tuners in my area, and I doing well so far. I need to know if there is a general rule that tuners follow in regards to ignition compensation for engine/air temperature.

Presently my water temp ignition comp. are Zero from cold right through to normal operating temp (-4*F - 194*F). Above 194*F, I begin to retard timing reaching75% retard by 250*F. Is this ok?

Regarding air temp, this is the one I am not sure what to do. I begin to retard from about from about 86*F reaching about 5% retard by 140*F.

Please give some advise.

thanks
