Aftermarket accelerator pedal sensor

[NBenson]

Hi, I'm Norm Benson out in California. I race a 2012 S197 with SCCA. I'm converting the OEM pedal set with a Tilton 3 pedal set and I don't know which throttle position sensor to use that will be compatible with the OEM ECU. With what I know now, my choices are:

Penny & Giles Specification:
Dual channel contactless throttle position sensor
Operating Angle : 90 Degrees
Output: 0.5 -4.5V analogue
Connection: 50cm Fly Lead with 4 wire core

Penny & Giles Connections:
Red : +V Supply
Black: 0V Supply GND
Yellow: Ch1 Output
White: Ch2 Output

OR:

Variohm Specification:
Dual channel contactless throttle position sensor
Operating Angle : 90 Degrees
Output: 0.5 -4.5V analogue
Connection: 50cm Fly Lead with 6 wire core

Variohm Connections:
Channel 1 (CW)
Red : +5V Supply
Black: Ground
White: Signal Output

Channel 2 (CCW)
Green : +5V Supply
Blue: Ground
Yellow: Signal Output

HELP! Can you shed some light? Thanks in advance. Norm

Hmmm , as far as using this with an OEM ecu I don't have the answer to that. I use the same pedal assembly with a Penny and Giles sensor but not with an OEM ECU. I am not sure if there is any ability to calibrate a pedal sensor on a factory ECU? If there is not, then you may need to try and measure a stock pedal at rest and see what the voltages are showing and try and match that with your new setup.. Maybe someone with more experience with that factory setup can chime in, but I would imagine your ECU will be looking for a specific voltage from the pedal relative to the throttle angle.

Thanks for the reply. That is the approach we are taking. Unfortunately the rules dictate we use the OEM ECU.
Cheers,

It may be easier to keep the oem throttle pedal and then just use a brake and clutch tilton assembly instead of the 3 pedal?

That will be the last resort. 2nd to the last resort is a mechanical linkage from the Tilton pedal to the OEM sensor. We are just diving into it... We'll figure it out.
Thanks for your thoughts... Cheers!
