I go out this morning to dick with the tune, and jump in to start it up. As soon as I got in, I noticed the same smell. Now I'm thinking, WTF. It must be something in the car. I smell around and narrow it down to what seems to be the passenger floorboard. ECU, no shit right? Before I do anything else, I start to car just to see what happens. It starts fine, idles fine, and acts completely normal. Now, I'm really like WTF?
I pull the ECU just to see what I can see. I smell the case before opening it up and immediately know something's up. I pop off the cover and here's what I found:
Now, my question is, why? I've recently swapped in a revised (black) ISC, and have been running it for a few hundred miles now, so I don't think that's it.
The one factor I'm wondering about is my wideband. This seems to have happened less than 12 hours after I hooked it up. But, the wideband is still functioning as it should. ECMlink still works, the wideband is reading correctly and everything. I hooked it up using the EGR temp circuit as an input, all according to instructions. I'm confident it is wired correctly, because the damn thing works. Could this be coincidence?
Thoughts, input, suggestions would be awesome.
