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
