New to the forum, little intro

My bus has had a l61 swap running in it since 2018. I went through 2 engines in that time LOL. Leadfoot.

So now shes running a 2009 Le5 E37 as a standalone, but im trying to get the small bugs ironed out that i didnt have with the L61 Ecu.

Currently shes got a 4,000k rpm cutoff, im assuming thats because theres no TCM communication, so its assuming its in P/N. I tried adjusting the Tcm loss of communication TQ chart. that didnt Correct the issue.
