Hey guys,
This is something that has puzzled me thus far. When street tuning, how on earth do you know when you have optimum timing advance dialled in? I mean, with fuel its easy enough, you have a wideband O2 to show you exactly what you need to know. But what about timing?
From my limited understand it seems that on a dyno, the way to adjust timing is to look at torque curves; optimal timing will be achieved when you have found the most torque, and moving timing either side will reduce torque output. How would you know where this point is on the street, when all you have is a wideband, possibly an EGT and your bum in the drivers seat?
Cheers :)
