Hello all,
I have a 2007 JK with a Gen 3 Hemi swapped into it using a TR4050. The swap is mainly complete, however I'm running into an issue where the ECU hard cuts RPMs at 4k RPM because it is not registering any speed signal. I know that the PCM accepts speed signal over CAN from a TCM. Is there any way around this in the tune? I know engines can run erratically for other reasons without vehicle speed. Any and all input is welcome!
Thanks in advance
