Rywalls Posted December 16, 2015 Share Posted December 16, 2015 I converted my car from automatic to manual but kept the auto ecu and loom. But then going through the gears it was limiting at 6000rpm instead of 7200rpm. Done loads of research but the topic isn't covered much and I ended up cutting the park/neutral safety switch wire going into the auto ecu, now the car is fine and revs as should. Problem is my engine management light is constantly on so without just taking the engine management bulb out or getting a manual ecu (I'm saving up for a syvecs which may take a short while) how do I get rid of the engine management light? I did read this thread and contemplated doing what the guy said in post two but how on earth would that work? http://www.mkivsupra.net/vbb/showthread.php?t=249622 Thanks Quote Link to comment Share on other sites More sharing options...
mellonman Posted December 16, 2015 Share Posted December 16, 2015 It would work by the means of the relay contacts would be wired through the neutral switch , the relay coil would be powered by something which is only on when the ignition is switched but not when the engine is running. Or you could just fit a switch/button to simulate the neutral switch . Ie you have to press the button to start the car. Quote Link to comment Share on other sites More sharing options...
Rywalls Posted December 17, 2015 Author Share Posted December 17, 2015 Thanks Mellonman So basically the ecu just needs a signal on startup to say the car actually is in Park or neutral (or so it thinks) for it to start? Quote Link to comment Share on other sites More sharing options...
mellonman Posted December 17, 2015 Share Posted December 17, 2015 Yep and if the signal is there permanently there it registers a fault. Quote Link to comment Share on other sites More sharing options...
