Does anyone wonder what it will be like in a few years when Holley moves on from this platform and you need service parts?
Heck, look at what a guy can run into getting current production MSD components serviced.
Valid concern, especially on all these units that are potted and cannot be repaired.
If that concerns you do what I did. Buy a kit from DIYAUTOTUNE.com and assemble it yourself. Save money and have a repairable ecu because you built it.
That being said I would imagine most of the failures out there are related to poor installs. You can let the smoke out of anything if you hook it up wrong. I would imagine a charging system in an old stock mopar would cause fits for one of these systems when the voltage goes to crap with the headlights on at idle.
