Guest EncoreWRC Posted February 10, 2007 Share Posted February 10, 2007 Can anyone tell me how to do an ECU reset. I tried fitting an Fcon Pro today but the mapping of it wont allow mine to run so will need a remap. My problem is that I have now reconnected by stock ECU and I have the engine management light up and the car wont starts - turns over and thats about it. On a ford, we would just disconnect the battery for a while and that clears the ecu. Are supra's the same or will I need technical help?

Ric Posted February 10, 2007 Share Posted February 10, 2007 take the -ve side of the battery off for 1 minute and put it back on Quote Link to comment Share on other sites More sharing options...

merckx Posted February 10, 2007 Share Posted February 10, 2007 Or remove EFI No 1 fuse from the fusebox in the engine bay for a couple of minutes. Quote Link to comment Share on other sites More sharing options...
Guest EncoreWRC Posted February 10, 2007 Share Posted February 10, 2007 Tried all this guys and not had any luck. Tried the fuse trick and the disconnect the -ve but nothing has worked. I left it for about an hour. Even totally disconnected the battery for a while. Now scratching my head....... Quote Link to comment Share on other sites More sharing options...
Jake Posted February 10, 2007 Share Posted February 10, 2007 Is it sparking? Is fuel getting through? Is the alarm/immobiliser turned off? Any stored error codes? Quote Link to comment Share on other sites More sharing options...

Jake Posted February 10, 2007 Share Posted February 10, 2007 You mean it's turning over not ticking over, right? How do you know fuel is getting through? Are the plugs sparking? error codes Quote Link to comment Share on other sites More sharing options...
Guest EncoreWRC Posted February 10, 2007 Share Posted February 10, 2007 Given up for tonight - I will check it all tomorow. The proble has only started since I disconnected the ECU Quote Link to comment Share on other sites More sharing options...
Ric Posted February 10, 2007 Share Posted February 10, 2007 is the connector back on correctly and the little nut tightened up so the connections are good? Quote Link to comment Share on other sites More sharing options...
Guest EncoreWRC Posted February 11, 2007 Share Posted February 11, 2007 I went out thisorning and double checked everything as I was working in the dark when putting it all back together. The ECU lom fitting was not on 100% tight and the nut took about another 3 - 4 turns. It now works fine - cheers everyone - you were all spot on with everything. Thanks Quote Link to comment Share on other sites More sharing options...
