hey guys,
long time no see.
i had a problem develop saturday night which has got me stumped.
symptoms are:
temp gauge died, just sits at bottom.
thermo fans r stuck on as long as ignition is on
performance is severly lowered- feels/sounds like its gonna blow up at 3500rpm
exhaust crackeling like a v8 supercar under gentle deceleration ie. when i lift my foot off throttle.

first throught was dead coolant temp sensor so i changed that, no difference.
i then noticed my J3 chip was hanging half in half out of the ecu (still waiting for final tune so i didnt put case back on)

im concerned that i could have shorted the ecu or the j3 chip.
i have just disconnected the battery to reset the ecu just incase that helps.

air con diagnostics reads that the engine temp sensor and the coolant temp sensor are faulty (errors 7 and 8 i think)

anyone got any thoughts?
cheers, Adam

if your j3 was half in half out, that could and most likely would make your electronics go stupid, try and plug the j3 in and see if it makes a difference, if not take it out and see if that makes a difference, i no of people having trouble with a dirty inlet on a j3, so defiantly worth having a muck around with that

tryed the ecu reset and blew the j3 chip out, put it back in.
no good.

whats the chance ive stuffed the chip or ecu?
otherwise any other suggestions?

wouldn't have a clue mate, never had much experience with ecu so i dont no how sensitive they are, try running the car with out the j3 and see if it has the same symptoms

yeah seemed the same so i assume ive blown the chip

is it possible that i shorted the ecu and its only effected the coolant temp sensor and engine temp sensor?
or would the car not run at all?

problem solved thanks to paul from CVE and 4dlvr

turned out i shorted out the J3.
pulled it out and symptoms stopped.

thankfully paul saves everyones tunes so its not gonna be costly to fix.

Make sure it's installed properly, as per the instructions, with a thick bit of gaffa or duct tape to keep it on the socket. Last thing you want is it coming off on a bumpy road.
