EndTuning

How it started vs. How it's going.
I frequently get M3 3.2 ecus for a coil driver swap, the same thing can happen to 328i's but with higher RPMs on the M3 Evo, it can be pulsing these a lot quicker. Sometimes they'll blow out and be dead, sometimes they stick on and burn out, this one however stuck on and did some damage. A LOT of damage!
