ecu? ews? problem
Posted: Mon Oct 07, 2013 9:47 am
Ok. So i went to finally track test my car at lydden hill last weekend... it supposed to be great... loaded the car.. tires.. tools.. get there on friday to be ready for saturday.
The car run ok.. no problems.. reved normally.. engine run as normal.. up to teperature.
Fthe time come to go on the track so i went. Did one lap... check everything and listen to odd noises as it was first lap.. (btw.. the power and sound of m62 in a e30 is awesome)
On my way to second lap the car cut off and died .
Towed it back to pits and after some checks there was no spark and no injectors working.. fuel was getting in as i checked the hoses.
I played with ews. Checked it with multimeter.. checked nearly everything with multimeter along with crank position sensor
unfortunately i forgot my diagnostic laptop... after long day i had enpught and went home... next day connected it to laptoop and inpa showe that ecu is not recognised or something like that with isn or something and that all the keys are free and used where im sure it showe somethig else before.. there was fww other checks i did bit that was just to check grounds and sensors.
I decided to take the ecu out and check it.
Took it out and there it probably was.. my problem.. seems like water find its way to plugs.
While taking the plugs out they were corroded abd noticed that one pin broked off the ecu itself and stayed in the plug
And now for questions... yeah.. the ecu is probably gone and ews is gone aswell..
Should i worry a out anything else to be burned..
I had a look inside ecu and you can see some water residue and what seems to be like burn staines.
Should i check it somehow or just get another ecu ews and chip. Anybody have any suggestions what to check?
