I noticed ecuflash doesnt show the whole serial number for the cable so maybe youre onto something?

 

It's definitely worth a try. When it happened to me, I checked every fuse in the car and traced every pin from both the OBDII port and the pin from the white connector to the ECU. All the connections were good and the car drove fine. I even hooked up my car to a running vehicle so I can get the 13+ volts while the evo engine was off .

Ended up finding out that it was my tactrix 1.3u cable all along. It turns out that if you keep them plugged in too long it ruins them. I found out the hard way.

 

He said even a code reader wouldn't connect to his ecu.

 

 

Going to unplug mine. lol

 

x3 on that one, right after I run the cable super clean through my dash & out my glove box lol

 

you can install a switch on the 12volt constant line going into the obd connector. So you can just turn the cable off. Its what i did with my openport 2.0 to keep it from draining the battery.
