i pulled my ecu board on my 02 wrx because i was having some proplems and found a burnt resistor.
Problems: i went out to datalog since i just got a new map from my tuner (stock image but scaled to new sti pink injectors) and as i started the log, about 3200rpm and <10 pounds of boost the car started bucking and hesitating real bad and all of a sudden my temp gauge pegged hot, oil light came on, fuel gauge went to zero and gas light came on (but had a full tank), the car died and the caution/hazard lights didnt work.
ive checked all of the fuses and they all check out fine, the car just had an engine swap with a new 2.0L but we didnt touch the wireing at all, all the grounds were just how they were before we pulled the engine.
so if anyone knows that the resistor T849 on the stock ecu board is or what it is used for it will be greatly appricaited.
i know im probably going to have to replace the ecu but i want to prevent the new one from frying too.
