Hey guys,
Stuck in limp home mode, still running a Manual ECU would this cause it? Was advised only difference between them is the Auto ECU will hold the revs up.

This was a manual -> auto conversion (don't ask), I've got the correct engine loom to the trans, have correct loom to the econ switch (as I heard that can cause it).

Not sure what else to look for. I've heard the auto has a separate computer but I've never seen such a thing?

V8 had seperate auto computer,
Six does not. All runs off the single ecu in the Six.

you need a auto ecu.
or a j3 with a auto tune.
