My car is in the shop ready to get on the dyno, but the check engine light is on and it does not throw any codes. I recently had my ECU flashed by TS with the L-spec. This is the only thing different that has been done to the car other than installing the greddy tt kit. The emanage was already on my car prior to the greddy so no wiring was done, just the tt's, manifolds, fmic, and piping install. Has anyone had this problem with the check engine light and no codes?
