I'm NOT trying to rev it 'in neutral'I am in the final stages of fitting a BA turbo engine into a Nissan Patrol and have had issues with throttle cut/ no boost.This arvo I finally determined that the ECU thinks I'm just revving the engine with the gearbox in neutral (when infact I'm actually driving down the street).I have done a flash tune which has been set as manual trans & no ABS (alternative speed input??). I have a signal generator plugged in to trick the ECU into thinking the vehicle is moving, but it makes no difference regardless of it being turned on/off. However it does read a speed signal on the data logger on Ford IDS, so I know the ECU is receiving the input.My question is, how does it know weather I'm driving or just sitting there parked? And how do I solve the problem? Edited 12/06/14 12:08 PM by patrol_maverick Link to comment Share on other sites More sharing options...

I'll wire it in and see what happens. Link to comment Share on other sites More sharing options...

I wired up the brake & clutch switches on rocker switches so I can activate the circuits. They read fine using IDS, but I still seem to be stuck in a neutral state.I also logged the inputs with the ECU back in the Falcon it came out of and for some reason it reads 'depressed' when the clutch pedal is released, and 'not depressed' with your foot on the pedal. Attached are the sreenshots with it in the Falcon. Link to comment Share on other sites More sharing options...

I have a U1900 CAN comm code, and when you log the CLUST_MSG its status says 'Yes' which I believe is an error message from no communication. Strangely, the BEM and ABS say 'No' for no error.
