PeteR34 Posted July 26, 2018 Report Share Posted July 26, 2018 Hi, After tuning up the car and started driving on the road I notice what I run high boost and over 5500 rpm the Check Engine light goes on (Steady, not flashing) All was well on the dyno with all the external sensors attached so shouldn't be a problem with knocking. (I wish though we had seen it while on the dyno to better diagnose but yeah, we didn't) I'm just wondering what is events that would trigger this? I'm suspecting it's triggering from some "jiggery" we had to do for the injectors (going to be changed) but couldn't find a table of what would generate this from the ECU.

Adamw Posted July 27, 2018 Report Share Posted July 27, 2018 You can set up the CE light to do whatever you like. Some may want it to function as a normal CE lamp, some use it for a shift lamp, or overboost warning etc. Going off your username I'm going to assume you have one of the skyline plug-in ECU's? In our GTS/GTR base map the CE lamp is set up by default as an over temp/over boost alarm, it comes on at ECT above 102°C or MAP above 230KPa. You can change these thresholds to whatever you deem safe for your engine or you can change its function to just do typical CE light functions if you wish.

Do your Aux 7 settings match above? Quote Link to comment Share on other sites More sharing options...
