VSS Signal E67
I need to get a VSS signal to the GMPP E67 ECU to let it know the car is moving (No ABS or traction control, manual tranny). Speedometer is GPS based so no connection to ECU.
- Not sure if the type of two wire magnetic sensor selected makes a difference (Dorman 505-5505).
- 16 tooth ring (Porsche style)
- 3.42 rear end
In the Speedo setting section, what needs to be set to get a better signal to the ECU (right now 60MPH speedometer = HP scanner @ 7MPH)
I'm not sure about:
1. Speed type choice (table 822)
2. Vehicle speed output (table 820)
3. Change the 40 to 16 revs (table 9002)
4. Ratio error (table 9052)
5. Ratio (table 9050)
Any insight to tis table will help improve the signal to the ECU, again, just need to ECU to know the car is actually moving.

If your radio volume adjusts with speed you can tap into that wire for VSS. I used it for my boost by speed signal on my controller and it worked perfect once you convert the signal to your ECU.
