Holley Pro-Jection and Premier Power Welder

Hey all, I'm considering picking up a Premier Power Welder for the CJ. I recently installed Holley's Pro Jection on the 350. Question is.. if I weld on the Jeep's frame with the Premier Welder, will it damage the ECM for the fuel injection? The Holley manual says to disconnect the ECM when welding on the vehicle but obviously I can't do that with an onboard welder. I've already welded on the Jeep a few times without disconnecting the ECM (forgot to do it), but that was with my shop welder. Any thoughts?

I think any electronic manufacturer will tell you that. I'm sure someone has blown out their ECM while welding. I doubt that Holley's is that much more sensitive than OEM ECM's. I would say that if you are welding in your shop to disconnect it. But like you said, how can you do that in the field? Maybe you'd want to carry a spare ECM, just in case. Oh the glories of fi. We didn't have to worry about this crap with carbs.

On another note, how close are you to VA Beach? A friend just moved down there and we were wondering where to go wheeling in that area? If you got any suggestions, I'd be happy to hear it.

Later, Hamy.

I'm about 30 miles north of VA Beach. Your buddy should link up with Tidewater Fourwheelers Club. It's based down there where he's at and takes trips all over to wheel. Hmmm.. guess I'll either take along a spare ECM or maybe a carb.

Seems to me the rule of thumb is welding on your own vehiocle you should reverse the polarity . if I recall correctly .
