Hilarious forum thread - 1.9sec 0-60.... in reverse
Someone made the mistake of asking an unpopular question.
If you have some time to burn go here and read through this thread. It's frickin hysterical.

DME Almost Fried During Flex Fuel Wire Install
I had a major scare the other day. In the pursuit of speed I decided to upgrade the BMS JB4 unit I have for my N55 engine to have the capability of detecting E85 and adjusting the DME accordingly. It should be good for somewhere around another 40 to 50 hp / tq.
I had to expose the wiring harness of the JB4 unit and first snip two wires. I then had to wire one side together and wire the other side together with an additional sensor that connects to the fuel rail. This sensor has a pin that then goes into a DB25 connector that plugs in to the JB4 unit. Scary stuff. I did everything as outlined in the instructions. I read the thing about 10 times to make sure.
Once all done I tried starting the car. It took a long time to start...then engine light...then dead. After this happened a high pitched ringing sound came from the car speakers until the battery was unhooked. Immediately I had a ball in my throat and felt ill. After quickly disconnecting the battery I rechecked all of my connections. The worst part was that I knew for a fact I had done everything right. The moment you realize everything was done properly is the moment you no longer know what to check next. I emailed the vendor and they quickly got back to me with some things to try. The first round of communications was the usual, making sure I wasn't retarded. During this back and forth I decided to just reverse everything and carefully inspect every part.
It's hard to see in the picture but it shows the problem. The flex fuel add-on module they gave me had one pin that was not completely seated. When connected to the fuel rail it just pushed itself out the back. I pushed on the corresponding wire from the back of the plug and it clicked into place neatly. At this point I was breathing an apprehensive sigh of relief. I still didn't know whether I had fried anything. I was so eager to try this fix that I scratched the shit out of my hand reaching back to the fuel rail connector. I look like a burn victim. I hooked everything back up and the car started up as though nothing had happened. No issues so far but I still haven't driven out of the garage due to weather. I remain confident though at this point. A very scary moment but it's all worth it in the end. It's just part of the ups and downs of what we do. I also learned that every component, no matter how much you trust the vendor, must be inspected very carefully.
