Hey Guys, hoping someone can help me out.
On two separate occasions now, my car has broken down with a flashing red cat temp sensor light directly after being nistuned.
The first time we thought it was the ecu, so we replaced it with another stock ecu. The car drove fine stock, a week later I had the nistune chip transferred across and the same problem occured a day later.
I'm convinced the nistune somehow has caused either the ecu or the sensor to malfunction. Or maybe the nistune chip itself is faulty?
Can I remove the sensor? What else could possibly cause this issue? Has anyone else had similar problems?
Thanks.
