TPS Scale (min) and Overrun Fuel Cut-Off (TPS)

My throttle closed reading is 0.49v. This gives a TPS (min) scalar -0.29% (negative). Is this OK or is it better to get it adjusted to 0.51v (marginally positive)?. This has got me thinking....please share your experience/know-how

Does Overrun Fuel Cut-off (TPS) need a positive (+ve) percentage like 0.1% or will it function OK when if -1.0% is input


The help file says that Scalar TPS (min) should be read with the engine off.
Mine is 1.45% (0.41v)

Image


With the Engine idling is -0.29% (0.49v) - Is the difference versus the TPS scale min -1.45% (0.41v) of normal? Is Throttle cable too loose or too tight, i cant figure it out....please comment.

the scaling is, like the name says, a scaling :D

that means, that the value you get is given as a reference.

like so: -1.45% reading = 0% value
76.15% reading = 100% value in program

everything in between is so something between 0% and 100%.

if you check the reading of TPS after scaling, you will see, that now it is without throttle pushed 0% and at WOT it is 100%

I think your TPS is not okay.

Replace your TPS.
