I'll have a look in the morning. O.1 to 4.9 is very close to the limit.
Is this from a Subaru?

The 0.1 to 4.9 (and vice versa) is from an AP Racing pedal box using a Penny & Giles SRH280DP/045/045/A4/5/S rotary position sensor.

Yes it is on a Subaru - 2006 Impreza STi
The other values quoted previously are notes from the Subaru ECU pinout drawing.

If you can swap the pedal outputs so they work in the same direction (low to high), we can already support that in mode 8.

The Subaru pedal I used has both tracks almost identical, and in the same direction.

As are any other DBW Subaru STI's I've worked on.

Thanks for the help.
The throttle position sensor is ealed and will need to be replaced to accommodate that, o now I know what to do if we decide to use the S80.

Agreed - Both main and sub are 1 to 3.5Volts (C to O) on the standard TPS.
The throttle position sensor we are using is part of an after market pedal box (see previous post) and to get synchronised signals I will need to replace the sensor.

Thanks to everyone who has responded to this post, I'm pretty sure I now know what to do should we opt for a DTA ECU.
