Bevan Sutherland Posted February 10 Report Share Posted February 10 Hi guys I’m having issues with my jzx90 plug and play ecu , have some all pre start checks and car does start fine but idles very high and is sucking air from my iacv which had been previously changed from having the vacuum hose to now just having a filter on the back as I’ve gone single turbo , this system worked fine on the stock ecu but now seems to be causing a massive vacuum leak, the stock iacv does not seem to be working at all but I’m not sure if I’ve missed setting something up in the ecu to remedy this ? Any help would be greatly appreciated Quote Link to comment Share on other sites More sharing options...
