JB4 Installed.

catcher22 · 02-22-2012, 11:03 AM

Was able to upgrade from JB3 to JB4 last night and take it for a spin. Overall, I'm very happy with it! Was too tired after the install so I only drove for about 15 minutes and it's still adapting to the tune.

The install did not go smooth because I rushed and simply didn't pay attention to detail. On the first attempt, I found I connected the large black connector backwards. Fixed that. Then I found that I reinserted the power wire into the incorrect position, so it wasn't getting power! Fixed that. Then I realized I hadn't pushed the connector back into the DME far enough, so fixed that. All three times were the same symptoms - engine wouldn't start. You can imagine how happy I was after I installed it right.

So for those of you who have install problems, three easy areas to overlook are above!!

That's funny...... Cause I made 2 mistakes when I upgraded mine. I caught mine before install. I was in such a rush my beautiful soon to be pita wife asked if I did it right, so of course I wanted to prove her wrong and that's when I found my mistakes

Anyway I love mine,
