D1andonlyantman Posted July 20, 2019 Share Posted July 20, 2019 Hi all. Got my car running on this standalone but the DBW is being a nightmare. The TPS works fine but the accelerator doesnt make the throttle adjust. Ive got the clutch on a switched 12v and ground, the motor on 'h bridge 1' as per the ecu manual, but the throttle only moves in the last 10% of the pedal travel when it becomes manual. Then it will rev and i see the throttle position change on the software. Other than that the throttle position is stuck at 3.5%. Ive checked my wiring 10 times, the TB has 5v on a pin, so i have no idea why it isnt working. The characteristics table has a linear 0 to 100 setup which looks logical, and as this throttle body is one of the presets i imagine most of the settings would be right anyway. If i set the ecu to show dbw fault on the eml is does light up, so it knows something isnt right. Has anyone got any ideas before i get a dbw delete? Seems a shame but im all out of ideas. Thanks Quote Link to comment Share on other sites More sharing options...
D1andonlyantman Posted July 22, 2019 Author Share Posted July 22, 2019 Got the bastard! The tps and throttle have 2 sensors each. The ecu was expecting 0-5v and 5-0v inverted of eachother. The supra doesnt do it like that so it caused a conflict and the ecu stopped any throttle signal. Switched to 1 sensor each, jobs a gooden. Thought id post this just in case it helps someone in 5 years haha Quote Link to comment Share on other sites More sharing options...
