Silece2k6 Posted January 30, 2018 Share Posted January 30, 2018 Hello everybody. I have a problem with my car. When the ECU is cold and I start the engine, the AFR runs 9.5, sometimes> 19. By the way, run in part only 5 cylinders. The Rpm goes up and down and makes Missfire when I push the throttle. If I heat up the ecu with a hair dryer before, the car runs wonderfully. Now you would think first that the AEM V1 is broken, but we tested the ecu in two supras (hot and cold) In the original Supra everything goes well, but when I install the ECU again in my car, it dives off again (when Ecu is cold) What I have further noticed is when you connect the laptop and the AemPro Software is running it sometimes freezes for few seconds. That makes no sense Link to comment Share on other sites More sharing options...

mellonman Posted February 4, 2018 Share Posted February 4, 2018 Have you checked your loom pins sometimes a leaking cam cover let's oil run down to the ecu plugs which can cause high resistance . Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted February 4, 2018 Share Posted February 4, 2018 Definitely sounds like a wiring or plug problem, especially if the ECU works fine on another car. Link to comment Share on other sites More sharing options...
Silece2k6 Posted February 4, 2018 Author Share Posted February 4, 2018 Yeah there Must be a Problem with my Car or wiring. Somehow the ecumaster Emu works Fine, But Aem says NO! Think the aem v1 is very sensitive. I have to Check the wiring an Plug connector Gesendet von iPhone mit Tapatalk Link to comment Share on other sites More sharing options...
