The current ECU is "melting" the potting off the back of it. We've had some pretty hot days this summer and I can only guess that's what caused it.
It's going to be a bear to clean that potting off of the inner fender. I figure it isn't coming off without a heat gun and a gasket scraper.
I'd really like to not have to do this again when the new one does the same thing.
I was thinking maybe painting it mat stabilize the potting.
I do like
@RustyRatRod suggestion. Maybe I can place a couple of washers behind on the screws to space it away from the inner fender.
