timming for f4r

[hissingsid]

Whats the most advanced timming do you think you can run on a competition engine and from what rpm?

I'm assuming you mean ignition timing. You give an engine what it wants, not what you think it needs. You'll quite often find if you keep increasing the timing the power will drop off, even before detonation occurs, so "more" isn't necessarily better

Yes ignition,Is there not a ballpark figure when you boys are tunning that comes up every time?

Worth mentioning what fuel you are running given that different octane fuel will have a massive impact on MBT of course.

 

[hissingsid]

Standard unleaded 95 octane and lpg 102 octane

You are aware the timing requirements will be greatly different on those 2 fuels so you will need a different map for each one?
