rpslaughter1982 Posted July 11, 2007 Share Posted July 11, 2007 Hi, I have fitted an HKS DLI to my single supe (AEM ecu). After fitting it it idles at 3000rpm! does anyone have any experience of fitting a dli to an AEM supra or know the reason why I am experiencing this idle issue?

rpslaughter1982 Posted July 11, 2007 Author Share Posted July 11, 2007 i'll just give a little more info: I first fitted the the DLI as per the HKS instructions which indicated to tap the power wire into the black orange wire on the 4 block connector of the ignitor. The car started fine like this but as soon as you touched the throttle the engine tried to cut out. I then wired the power wire to the black orange wire after the noise reducer as per - http://www.97supraturbo.com/Tech.html - after doing this the car idled at 3k rpm. I would be really grateful if someone with a jap spec non vvti running a HKS dli could tell me how theirs is wired up. I need to know if my dli is faulty or if my wiring is faulty or whether it is another problem, many thanks Quote Link to comment Share on other sites More sharing options...
Wez Posted July 11, 2007 Share Posted July 11, 2007 How many wires are you connecting up? I fitted mine a long time ago and I recall six ignition wires and a fused power feed, it was a while ago though. I am also using an AEM ECU and it should not affect your idle at all, its kind of an invisible mod, as in you shouldnt notice any difference apart from no ignition break up above .8bar Quote Link to comment Share on other sites More sharing options...

I have no clue why it has efected my idle so greatly Quote Link to comment Share on other sites More sharing options...
Wez Posted July 11, 2007 Share Posted July 11, 2007 Did you disconnect the battery during the install? The AEM ECU sometimes needs one power cycle to reset the idle control valve, therefore the second time you start the car it should idle ok, have you tried this?

dandan Posted July 12, 2007 Share Posted July 12, 2007 Sounds to me like you fited it ok. I agree with Wez - do the reset as it sounds like the idle valve is open way too far. Stupid question - have you looked for air leaks into the plenum/runners and is your throttle butterfly closing fully? Quote Link to comment Share on other sites More sharing options...

I did check all the hoses going into the plenum but I haven't checked the throttle yet. As soon as I finish work I'll have a look Quote Link to comment Share on other sites More sharing options...
rpslaughter1982 Posted July 12, 2007 Author Share Posted July 12, 2007 just started the car and it was fine, must have been the aem idle problem. thanks for your help all, I was at a complete loss. Now I can back to mapping! Quote Link to comment Share on other sites More sharing options...
