Hi,
I just needed to replace my TPS (throttle position sensor) and im uncertain of the correct factory spec TPS signal voltage. I have it currently set to .8V on closed throttle, and WOT is at 4.2v. There is no information online in the manuals or on these forums… So I was hoping someone could point me in the right direction without me having to constantly take the whole airbox assembly out over and over again trying to figure it out from trial and error.

Try 0.5v as a base and up to 4.8V is OK , let it warm up for a bit so the ECU learns the new setting , it will talk to your idle speed controller to set a stable idle.
Hyosung makes a lot of manuals but sometimes don’t always include every little detail (some manuals have more details than others), but the 650cc manual isn’t too far off (Both 650 and 250cc used DAEWOO ECU’s on the early models but obviously a 650cc ecu won’t work on yours)
I never paid attention to the OEM values as if a TPS went, I just replaced it and used a good judgement and set it.
