How to read TPS voltage via Classic FAST??

[BIGONTS]

I need to readjust my TPS due to swapping throttle bodies. I have a Classic FAST on my car and I hear you can see it through a scanning device. I do not see the TPS voltage anywhere on my dashboard or anywhere?? All I see is TPS %. Is there another way or reading it or am I reading in the wrong place?? Thanks

.42 should be good

tps is shown as percent
should be set to just below the idle setting in your program ,
the true tps voltage doesn't matter much but there are tables that are based of the idle parameter setting of usually 13% with the idle% number set to the same or 1 higher than tps so adjust the tps to the idle % setting is the right method rather than changing the idle % number


connect up and look at view> idle functions> idle parameters.. max tps for idle% should be 13 but it may have been changed by someone.
you don't want the tps to be above that setting

tps stock is set at .42 using a voltmeter but i'd concentrate more on getting the iac step count as it should be as if you were on a stock ecm keeping the tps below the idle % setting and get the iac around 10-20 warm idle . once the iac is set correctly then tweak the tps up to correlate to the idle % setting

Correct. The FAST doesnt care where your TPS is. It can be .42 or .62. The issue is you need to make sure its setup where its not in an off-idle setting within your program.

Stock ecm needs .38-.46. As .48 is off idle.

icecold1132, I know what it's suppose to be at, just wanted an easier way to set it without using the volt meeter.

Thanks for your input everyone. I'll look into it.
