increasing throttle response? flywheel or throttle body?

[JohnL]

So when you put your foot down it the voltage reading should go directly to and stop at 4.5V solidly?

Yes. If you're having to push the pedal hard to reach the max output voltage then I suspect the pedal might be hitting the carpet before the throttle wheel hits the TS on the TB?

If the TB TS is coming into play before the pedal hits it's stop, then when you push harder on the pedal the cable, throttle wheel, spindle shaft and shaft bearings may become excessively loaded (wear and tear).

Mine kinda is pushing from 4.43 or so till 4.5 and even goes over too 4.55...

Erratic voltages at the CT and WOT might suggest wear in the spindle and / or bearings...?

So it should STOP at 4.5 when it contacts the WOT plate?

That's the number I kept seeing when researching on the net...

If so I would set WOT at 4.5 upon contact of the WOT plate then set CT via the TS yeah?

That's what I'd do...
