s-afc 50% pedal shows 100% throttle?

Well I know this is probably just a disadvantage of the limited plunger type of TPS sensor we use but is there any way to get around this? When i push the pedal down half way the s-afc says 100%

no. the 87-88 turbo will max out the S-afc at 30% throttle. you just have to put the min at 97% and max at 98 or so.

If you wanted to, you could get the whole 89-91 t II throttle body, but that would probably not be worth the hassle. I have mine set at 99% for HI throttle, and I would probably set the low at around 75.

you just run the part throttle TPS to the S4 ecu. it's the same for both. then just run the full throttle tps to the AFC.

the serious 5 had two sensors, full and half or something along those lines, he's saying hook up the series 4 ecu on the half, and then hook up the S-AFC on the full range sensor, should solve your problem. I think that's what he meant anyway
