burnt V500
So I sent the ecu to Wolf, and they concluded the following:
"We have had a look at your V500. There is substantial damage to pin 29 (sensor ground). This pin has received a massive amount of amps as the pin has melted away. There are several resistors and capacitors blown.
The board has received damage as well. There are sections of track burnt away and there looks to be three sections of the 16 layer board that are showing signs of heat distortion and internal damage.
Two injector drivers are not working properly this could be due to the heat distortion on the board.
We believe there is only two possibilities for this happening.
(1) There has been 12v applied to pin 29 directly.
(2) There may be some form of bad earthing to your motor causing a high amount of amps to be drawn through the ecu while cranking the motor.
As this is not a fault of the WOLF it cannot be repaired under warranty. This unit will require a new board fitted as we can not guarantee repair of the old one with the heat distortion.
The cost of repair will be $1000.00 AUD."
I did not connect pin 29 to +12v. They also suggested in another email that perhaps due to a bad ground, the starter was pulling current through pin 29. Just before the death of the ecu, I was actually spinning the CAS by hand and that's when it burnt up. Thus, the starter could not have pulled enough currents through pin 29 to kill the ecu.
Due to the tremendous usage and support of the Haltech E11 v2, I might have to cut my losses with Wolf and switch to Haltech. There are many people running this ecu with a 20b.
