So question- B6614 does that need to be changed to zero to get rid of a rpm (rev limit) trying to shift a 2005 ppl Tahoe and it hits 5800rpm and it cuts everything out spudders ( sounds like rev limiter) everything is above 6100rpm (fuel cut off) I found this morning going through the tune

What is your rev limiter set at and what RPM are you logging?

In order for a shift to be commanded an RPM and speed BOTH need to be met. If you have your RPM met, but you are not going fast enough, the shift will not take place.

correct- I'm commanding at 38 mph shift at 5800rpm

if calculations are correct at 45 mph I'll be at 5797 rpms

i couldn't remember if it had to be within 5 mph of each other
