daniel_g Posted October 11, 2016 Share Posted October 11, 2016 1.2bar is about the limit of the standard MAP senosr so that could be your issue. Quote Link to post Share on other sites
Darren86 Posted October 11, 2016 Author Share Posted October 11, 2016 Could it be a faulty map sensor or faulty coil ? I was reading about the different codes on ecus and my standard one was 10100 black sticker and the jam is 10040 green sticker and read you had swap two pins and when I looked pin 7and 15 was different so swapped them and now have no engine diagnostic light but before I swapped the wires in diagnostic mode it would read code 14 it's decking my head lol Quote Link to post Share on other sites
Darren86 Posted October 11, 2016 Author Share Posted October 11, 2016 Also why is it not reving to redline when the jam is supposed to raise rev limit to 8000 ? Quote Link to post Share on other sites

Darren86 Posted October 11, 2016 Author Share Posted October 11, 2016 Just soldered the wires back to normal on connecter 2 and going reset the jam ecu and see what fault codes flag up Strange though as no codes appear on stock ecu Quote Link to post Share on other sites
