Bypass TPS function on NMU?

[NeverEnough]

How would I wire up the system to bypass the TPS function on the NMU and instead like to use a WOT microswitch instead? I do want to still have the seperate arming switch, though.

What are you trying to accomplish by bypassing it? Do you have a setup that does not have a TPS signal? Bypassing the TPS is not something we generally advise people to do though it can be done without hurting anything and I can try to help you. You will have to figure out a way to only put 5 volts to the switch as a 12V source would burn it up.

Can't seem to find anyone that can tell me which wire I need to tap into on my car. It's a 2010 Genesis Coupe 3.8 w/drive by wire. I'm used to old school cars w/throttle cables.

Finding the wire is simple. You will need a volt meter and use it to test which wire gives off a 0-5 volt signal. The signal should be about 0 volts when you are not on the throttle and it should go up to about 5volts when you press the throttle.

Thanks. Should be fun doing it with no one to depress the pedal lol.

Can you give me the info needed to bypass the TPS function on the NMU?

On the Genesis Coupe the only place you will have to get a 5 volt source will be the TPS so yes you could use the micro switch to activate it but you would still have to find the wire on your TPS sensor to provide you with the 5 volt source. The Genesis Coupe will have one TPS sensor by the pedal and one up by the throttle body. Since it is a drive by wire vehicle you can also turn the throttle blade instead of pushing the pedal if you have no one out there to help you.

I hit all 6 wires on the TPS connector w/my multimeter & 2 of them (black & white) have 0v no matter what & the others show the same voltage. Now I am being told that I won't be able to find out which wire it is unless the car is moving.

Also, since you mentioned 0 to 5v I am guessing the NMU looks for a rising signal & not a falling one.

If you can not get a reading by depressing the pedel try manually turning the throttle blade instead. The NMU would work reading the falling voltage sweep.
