I got my car back from the dealer today and was told that my Tuned ECU has a memory fault in it, which as a result is causing a hesitation, backfire, surge situation in first gear from a dead stop. The dealer wants to replace the ECU, at $1200. I politely declined. <p>I'm wondering if there is a way to determine what caused the memory fault, the flashed tune or just age. It's the original ECU, so its 13 years old. My understanding is that it is extremely rare for a ECU to go bad.<p>Thoughts?
