Seeing if anyone also had similar issues.

Mods - OFT, Tomei UEL Headers, Invidia R400 Catback

Last Weds I was leaving for work in the morning, came to a red light, car stalled and died. Tried turning the car back on but nothing, wouldn't crank over, display was saying "Coolant Temp High".

Ended up getting it towed to a shop to see what was up and they concluded the ECU was fried. OFT, OBDII Reader and the shop's computer couldn't detect an ECU.

Weird thing is, the mods aren't recent. The car has been OFT tuned and running for over a year and half. Nothing else has been done to the car since then (other than the regular maintenance of course).

Any ideas? Shop has never heard of an ECU just dieing like that.

Good news is that we did find a replacement ECU off a wreck that we can swap in and reprogram.
