HEI upgrade, wont start (no spark?)

Only if you make thoughtless choices of parts.



You think most of the Mopar-type ECUs available now aren't Chinese garbage? LOL, they are. You have to shop carefully and be a picky bastard no matter what car parts you're buying.
Hey Dan, I used accel, master pro, borg warner, D.u.i lasted a year , but they would all go out hitting 5000k. Mopar Ecu is Chinese made no doubt about that but lasts longer, maybe for a daily driver that doesn't push the slant too it's limits h.e.i will work but for me didn't work out.
