2007 JK Hemi Swap
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

did you raise the RPM in park in fuel cutoff?

Yes, I tried this among other things. Under the trans tab, the manual trans option is enabled. I'd imagine if I set it as an auto it would cause other issues. It does have a setting for power train protection - minimum speed is the parameter. But I don't have speed input?
