ECU remap, need help
Hi,
I read a-lot of recommendations for remapping my ecu with quantum auto. I got it in the mail today and installed it. Before I had no problems with my car but after running for a few minutes I got a cel and VSC light on accompanied with rough idling and what it seems like misfiring. I swapped the old ECU back in and the same issues are prevalent. I parked her and disconnected the battery while I am at class. Any idea what could be the issue? I will take it to auto zone tomorrow get the CEL fully diagnosed.
2002 LS430, no CEL or anything, with 225k
