I had a local shop put an MSD Opti-spark in my LT-4, the unit was not putting out enough voltage so they put in an Accel unit. It shouldn't mess up your ecm. Summit told my shop that they had several of the MSD's that were junk. Just what I learned, thank GOD you don't have an Opti-spark. Regards-Phil
