So I sent my ECU to ECM Tuning to get some damage repaired and chipped last week and today I got a response about the damage repairs needed. Seems the ISC driver kursploded from a short, which explains why it was unplugged. The OEM replacement seems to be big money. Has anyone had any luck with the one offered by Rock Auto? Are there better options I'm not finding? I have yet to OHM mine out but with the motor unplugged and the damage I'd say there's a good chance it's bad.
EDIT: I forgot to mention stumbling upon the DSM ISC website, while an option, it's still about $90 more than Rock Auto.
