Just a quick update on the ECU fix. Done and dusted. Took ... 15-20 minutes beginning to end. Just copied Chuck's image. I did notice Robert unplugged the pump when he reinstalled the ECU but I figured it is dead anyway so left it. Cleared codes and ran it and checked it again and all good. Oddly, n...

Okay, thanks Chuck. Bottom line is to do it the same as you did it in the posted pic so that sounds good to me. Not sure about all the different series. I looked up the Flashed ECU you mentioned. That is a very nice gain in HP. I had one that was 'chipped' for awhile and it would leave rubber in 3 g...

There is a "A" side and a "B" side. On the "A" side, the "30's" are on the top. On the "B" side, they're on the bottom. Install your diode like I did in the pic. That is correct, A32 to A37. I see the "A" and "B" now Chuck and it...

Huh, that is my exact problem. My '30' is on the opposite side of the gap than yours. Your fix looks the same as the RobertDIY video but my numbers (on the other side) are on the left side of the pic ... ?
Not sure what to think

Looks like I just flipped on to the next page. Sorry for the confusion

sorry, no idea why my reply's are going to another page rather than responding to the topic. Not even sure they are getting there now.

nope - all could do to edit this
