S4 Tps
 

Can I use the stock S4 TPS for the E6K?

Im almost positive it will but I read on the E6K install writeup by Brian D. Cain and Jon Kwahk that it wont work. I dont understand this because the e6k manuel calls for any variable resistance tps and i thought the stock tps was variable resistance and would work. Didint want anyone to think it was a stupid question....
Thanks,

I thought the s4 just a throttle switch??

Type in complete senteces. It doesnt take that much effort...

I just need to know for sure if the stock S4 TPS is the variable resistance type?

The S4 TPS is a variable resistance type and should read 1k ohm at idle and 5k ohm at WOT.

it will work with the e6k, the problem is that on series4's it only works for the first approx 40% of throttle movement as it runs out of travel, with the later model series5 they had two of the s4 tps switches. As they are a potentiometer you can change the way the cam moves the tps so that it gets full travel. or get hold of the s5 tps set up.

potentiometer- you lost me...but i know what you mean about running out of travel. I was playing with the TPS and saw how it only makes contact with the roller thing about 40% of the time. Thats when I started checking it out...So if I do use this S4 TPS, is the E6K going to only register up until the TPS stops making contact?

I'm sorry for leaving out the "had".

If you thought that was bad you have A LOT of correction posts to make in the lounge.

Setzep- my fault, Im just want to get my car running...do you know if what im saying about the s4 tps only working 40% of the time if I use it? I just want to try and start it up after I get the engine back together and i guess i'll just have to try it until i find a haltech tps...

a potentiometer is usually a sensor that measures single plane motion rather than rotation, ie in and out.
if you can get a haltech tps that would be the best, takes a bit of mucking around to mount but worth it.

I would guess the Haltech woulden't like it if could only read 40% travel of the throttle. The one I got with my E6K reads full travel.

Actually a pontentiometer in the electrical sence is just a resistor with a variable center tap, and they come in all different shapes and sizes. Most these days though are put into rotating assemblies and are used in things such as knobs to allow analog adjustment, like the volume knob on your stereo.
