So i recently got a 05 sti shell with no motor and transmission and swapped everything over from my wrecked 05 sti to the new one (the shell). Before it was wrecked it came with a hi-flow cat down pipe (no name) and an aftermarket exhaust (no name) but it had no accessport. So I’m assuming it had a stage 2 tune to run the downpipe. So now the new one drives fine and everything but it’s flashing a check engine light rapidly but no codes come up. We even switched the ecu and body control module and it’s still flashing. I’m getting a new accessport on Monday so would i need to put the car back on the stock map and then back to the stage 2 tune from Cobb to get rid of the check engine light? Sorry if it’s a bit confusing
