I had an engine loom made for my vehicle (Escort Cosworth) which has DBW incorporated into it.
In the attachment, I have made a schematic of how it is currently wired. Can anyone confirm it is correct?
Parts used are a Ford Fiesta Mk6 pedal (6PV008567-01) and a Bosch 0280750156 throttle body.
I have run the DBW wizard and all seems to be ok as it does go through all the motions, however when the car is running, there is no throttle response. I guess it is either a wiring issue or software change required.
Wiring is correct, only thing I can't confirm is that the pedal's main pot is connected to the TPS input (pin 18 on Black connector)
You can upload your tune and log of the issue and I can take a look at your settings. Quite possibly a setting error with the safety parameters. As a test you can disable the plausible check on the pedal and see if the ecu reacts. The options for check type are not well defined in the V2 firmware, you could have the wrong one selected putting the DBW into error.
Check types include 1/2 main voltage, or inverse (sum=5), and one other odd. in the graph log you can see what both pedal inputs are doing voltage wise and choose accordingly.
I will try and go out to the car over the weekend and get some logs from it and post them.
So, an issue I was having was when starting the car up, as well as no throttle response, the rpm would increase itself.
In the software, I ticked the Invert motor direction, and Pos sensor input to B4 and Pos in sensor input to B17.
This has now stopped the rpm increase and does allow me to use the throttle pedal. But, when the pedal is released, the rpm drops and engine cuts out. Most likely something in the settings again that needs to be altered.
Sounds like progress.
Yes idle settings need to be calibrated to suit. perhaps the idle ref table needs to be increased and or the dbw idle range limit.
for reference. meant to upload these yesterday.
Think I have it cracked. On the DBW parameter, I had to increase the Idle range setting to around 34. This now lets the car start and idle without having to touch the pedal.
