im been searching for hours all around the web trying to find and answer for this dilema guys,i installed a third gen upper intake manifold and ported tb on my 88T2
and the questions is do i need to keep my narrow band tps or theres any way to wireup the S6 tps,are the values the same? i seen this done on S5T2 but not on S4,it is possible?

 

keeping the stock ecu off course

 

Well... the FD and S5 are both full range, full sweep TPS. The FD however can be used as the S4 On/Off TPS, you just have to wire it up differently.

Someone Showed Me This Before.... I cant remember who.. but I copied It!
heres how you wire it if you have a s4
fd tps with tab up
prong 1 is ground=black and brown
prong 2 is (narrow)signal= green/red
prong 3 is 5 volts= brown/white
**** 4 is (full range) signal= leave unplugged because you dont have full range (s5 does)
