So when running lean - as I´m planning to do 20-22 AFR... how mugh ignition timing is needed compared to stoich 14.7?
A friend of mine says that more timing is needed because the combustion at such lean mixtures is actually slower than stoich.
I´ve had a hard time figuring out how much timing is used on the standard engine... no logging software available for my stock 1998 ECU
