Cut off is just that. A rev limiter. Cut in is where it will start working again.

Im just not sure if that table is active in this code...but the rev limit table says(not used) So im guessing that this one, the( fuel cut off), IS the one being used.. That car really struggled to shift @ WOT and the cut off cut in is so narrow in Rpms that I never even though that a fuel cut off was the issue. Took me a hour to find that table and relize that its not right.....The engine did make it over the limit though to shift, but like i said it was really sluggish. I really hope thats the issue.

Actually the Rpm limit is this 5349 is the cut in and 5461 cut out Rpms. Opps i replyed with the wrong #'s before. But anyways if you look at this log really close you can see the Rpms bounce a little at those Rpms, its suttle but it is there.
Let me know what ya think??? Look like that limit is working on that datalog??? Rows 30, 31...and really from 56-66 rows....

Wow blowing the entire intake off...that will give me nightmares... But i do think im on to somthing in the code, so as soon as the slow melts off well see if it helps.

That wasn't just the intake, that was also the head.
The rev limiter is always active.
The man who says something is impossible, is usually interrupted by the man doing it.
I changed the Fuel cut out. Thanks for the help on that. Hope that was my high Rpm problem, as I would think it would be.
Anyways wish me luck tommorow as is gonna be about 50* out and sunny, so I will be driving it tommorow as a "daily driver" to go shopping in a town about 30 miles away. So Im not going to be beating on it, I just want to make sure the TCC locks up right, it drives smooth, and hopefully when I get closer to home I can open it up a little and see if that WOT is better.
Even though I am gonna be racing it, it still has to be reliable, and tommorow, a hour of datalogging should help me dial in crusing AFRs and smoothness on more of a spring like day with temps higher.

Just a scare tactic so your careful! Besides you don't have forged pistons so yours wouldn't blow off the top end, it would be the bottom first... You have a good knock sensor and knock retard data, like my LT1 it will report how much timing taken out not just knock counts, but how much knock.
So many people want to add MORE SPARK for MORE POWER! I'd rather be all safe power...
