Voltage for LT1 TPS?
I was playing with my new AutoXray tonight and my TPS shows 0.68 at idle and 4.15 at WOT. The manual says the reading for WOT should be 4.6. Will that effect the overall performance in any way? Thanks!

I am adjusted at 5.6 at WOT. When I did this, I felt as though the throttle response was a bit quicker. Not sure of any real gains though.

Re: Voltage for LT1 TPS? (40th_roadster)
Your numbers sound fine. Most likely your TPS sensor is non-adjustable anyways. If you want to verify, your AutoXray should also list the throttle angle in %. If it shows you 0% at idle and 99% at WOT then you should be fine. While you are at it you may want to verify that with the pedal floored, your throttle blades are horizontal, just for peace of mind.
Not sure how one would get 5.6 at WOT. The input voltage should only be 5v, unless something changed on later LT1's :skep: .

Lik eVince said, the tool should also show what percentage of throttle the computer is reading. It should show 100% at WOT which it probably does.

I'm .59 idle, and 4.02 WOT.
Before making a slight adjustment of the TPS my car was 3.53V Wot and still measured 100% on TPS percentage.
