I was using my EFILive to show the injec. balances. I did it on my truck with no problems.

Then i took it over to my dads truck (Grey Ghost)(02 LB7)
I did the same procedure from my truck to his and everything went fine until we noticed the rev limiter. Its right around 2200rpm.. After the confusion i decided to flash his stock information back into the truck. But still, The rev limiter is at 2200rpm.

Any idea guys?

Under Parameter ---Rev Limiter "Max RPM Allowed By TCM" it is showing a value of 3468.

To clarify, 3468 is what is called for (set), but the engine will not rev over 2200!

I am at a loss!!!!!!

GOT IT!!!

For some reason EFI thought i had a PTO..the max rpm for that was 2200. I changed it to 3648, flashed into the ecm..and HAHA.. It worked..

Thanks for taking the time to read the thread.

Odd. Good thing you figured it out. That sort of thing is hard to diagnose over the internet.
