OD light flashing

Unread post by Canuckstang »

Anyone have any idea why the OD light is flashing. I auto swapped my 5 speed Mach 1. It is controlled by a Quick 4 because I didnt have an auto ECU from a Mach 1 (hard to get it seems and pricey too). Im in Canada so the price is even worse for me and I got the Quick 4 used here in Canada.

Are there any parameters I can check in this strategy to disable in case I inadvertently turned something on?

Yes I have since read that the GT ECU is the same...I'd like to get away from the quick 4 and just control the trans with the ecu. I need the wiring harness too...but thats besides the point...Any year that is preferred over another?

Yes I am using the mach manual cal....AMZ2
