SAFC 2 won't show throttle %

[tomlaw]

My SAFC 2 will not display throttle % but everything else works fine. I have a base tune on it right now (thanks to Devin @ Boostin) but I am unable to get my tune finished due to the lack of proper throttle readout.

I have checked for continuity with a volt meter for the grey throttle wire in the SAFC 2 harness and continuity from the tps to the ecu and it checked out fine. This seems to have ruled out the possibility of a bad throttle wire in the harness or ECU (Keydiver). Again I am running a base tune and I would think I would be experiencing some other tuning/driveability issues if the ECU was not properly interpreting throttle position.

I have also tried plugging in someone else's SAFC 2 into my harness and theirs did NOT show throttle % either, while it did display the other settings properly just like mine does. This seems to rule out the possibility that my SAFC 2 is bad/broken though the 2nd SAFC 2 I used could have been experiencing the same problem as mine.

Feel free to chime in with any suggestions, thanks.

Sounds like you have it hooked to the wrong wire, the tps isn't working, or the tps is not connected all the way.

Check the wiring diagram in the pamphlet is wrong. you want the white wire with the red stripe. That's the throttle wire on the ecu. Also make sure the safc2 has throttle type set to the arrow pointing northeast. look at the wires, make sure the gray throttle wire is going to the white wire with red stripe. Check that first make sure that works for you.

Hey guys thank you for your assistance. I actually figured it out and got it working. Everything was hooked up correctly and in good working condition. I ended up going to "sensor check" on the safc 2 and that solved it somehow...the throttle % shows correctly now.

Thanks again.
