bens747 Posted October 25, 2008 Share Posted October 25, 2008 My overdrive light flashes periodically. Sometimes not at all and then it will have a constant on off flashing. Turn the engine off and it will reset. I saw in a previous thread that it might be the kph-mph converter chip. For what relevance this has to the flashing overdrive light I don't know. But the poster said it sorted the problem. Question .... Anyone had any experience of this problem and where the hell is the kph-mph converter chip. Thanks guys......

JustGav Posted October 25, 2008 Share Posted October 25, 2008 The convertor is usually installed behind the clocks as it intercepts the signal from the speed sensor before it gets to the speedo, from there it goes to the odo and then to the ECU. If your speedo is working fine and your odo is clocking up fine, then it could be that the connection wire to the ECU that isn't right.

Guest SUP_R_G Posted October 25, 2008 Share Posted October 25, 2008 maybe im wrong (more than likely), im sure it flashes to the off position when there is a chance the gearbox is overheating? Quote Link to comment Share on other sites More sharing options...
derek300zx Posted October 25, 2008 Share Posted October 25, 2008 I had the same fault, got kmh/mph chip changed and it fixed the problem. Quote Link to comment Share on other sites More sharing options...
bens747 Posted October 26, 2008 Author Share Posted October 26, 2008 (edited) I need to delimit the 112mph top speed. Would it not be better to replace the kph-mph converter with a new kph-mph + delimiter unit from Thor Racing and see if that cures the problem ... Thankx guys ....

bens747 Posted October 26, 2008 Author Share Posted October 26, 2008 That would be my line of attack Thanx Ian .... I think that would be better idea to attack it all at the same time. If the O/D light still flashes at least I can break the sound barrier at 113 lmao. Nice Supe by the way mate :thumbs: Quote Link to comment Share on other sites More sharing options...
