Default PE control past 7200?

My new combo is still making the power at 7200, which is currently my limiter. On the PE table there is no adjustment past 7200. What will fueling due at say 7400? How do you control fueling past the 7200 point? Thanks fellas!

John

VE goes to 8000, so you could "experiment" with that...but I wouldn't want to be the one typing in the wrong number on that one. Not a whole lotta time to react way up there in the stratosphere...

Yeah, I don't want to risk anything. I'm sure the PE will carry over some, as it does between cells. There are a few guys on here spinning theirs up pretty high so maybe someone can point us in the right direction. Might be a good time to do a SD tune!

Any time is a good time for an SD tune.

There is a LOT less cylinder pressure at 8000 RPM than there is at 4000 RPM so don't be afraid to work on it in the VE.
The idea is the same. If you were going to have the PE add 20% fuel on top of the VE, then just add the 20% in the VE instead.
It's pretty much all the same.
Some people even zero out the PE and do all tuning in the VE. It's not a problem to fear.
