Use a comparotar, something like a 339, I think is the number.  Op-Amps can
get twitchy, for enables.

| 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
