Help on op-amp (?) circuit

[Gustaf Ulander]

Hi folks

I need some help on a somewhat trivial (?) circuit.

I want to use the throttle position sensor (TPS) on my Ford Sierra (Bosch
L-jetronic/Motronic) throttle body to activate a relay switch (12 volts) on
my turbo setup. I also want to be able to adjust the point where the switch
activates.

I think I could do away with a LM 324 or LM 328, but I'm not sure, and I
also would need some hints on how to design the complete circuit.

Hope someone can help me out here.

Regards

Gustaf
