Benji82 Posted June 8, 2011 Share Posted June 8, 2011 Hey Guys, hoping someone can help me out. On two separate occasions now, my car has broken down with a flashing red cat temp sensor light directly after being nistuned. The first time we thought it was the ecu, so we replaced it with another stock ecu. The car drove fine stock, a week later I had the nistune chip transferred across and the same problem occured a day later. I'm convinced the nistune somehow has caused either the ecu or the sensor to malfunction. Or maybe the nistune chip itself is faulty? Can I remove the sensor? What else could possibly cause this issue? Has anyone else had similar problems? Thanks.

paulr33 Posted June 8, 2011 Share Posted June 8, 2011 run stock ecu diag from the consult port or plug in nistune and surely it has some sort of diag? apexi powerfc has the hand controller with on board diag and sensor display surely nistune has some sort of diag if consult doesnt work (it should) Link to comment https://www.sau.com.au/forums/topic/367148-r32-gts-4-post-nistune-ecu-complications/#findComment-5856283 Share on other sites More sharing options...
MrStabby Posted June 8, 2011 Share Posted June 8, 2011 Who did the tune? It could be too lean. Link to comment https://www.sau.com.au/forums/topic/367148-r32-gts-4-post-nistune-ecu-complications/#findComment-5856579 Share on other sites More sharing options...
DVS JEZ Posted June 8, 2011 Share Posted June 8, 2011 Its going into limp home mode. Check the nistune board is still held into the 20 pins correctly. Also check the 4 wires for the board are connected. Check all solder joints. Check that the board has been hot glued so it cant come loose. Where are u located?

Benji82 Posted June 9, 2011 Author Share Posted June 9, 2011 We swapped the nistune boards thinking it may have been faulty. Trent at Chequered has been extremely helpful and hopefully have it sorted this time around.

STATUS Posted June 9, 2011 Share Posted June 9, 2011 i think we got a bung board No diag faults logged and weird delivered timing, swapped out the board tonight so fingers crossed its fixed... Very odd as we have never had a board fault in 4 odd years... always a first though.
