can someone tell me what voltage the ecu will see after installing an afc at around -30 percent, at idle before and after the afc please

 

why are you asking? whatever the voltage is before the afc, subtract 30%...I believe idle is 1.7v from the MAP, or I could be talking out my ***...it's 2.8v FROM THE MAP with "Key-On" ie. the engine not running, I know that...

 

cause i had a bad map before , but im sure i saw 3.8 in and 3.8 out with the key in the on position. now if i switch how it should be wired ( normal way yellow to ecu white to sensor) if i switch that i get 3.8 in and 2.8 out all with the ket on , but the sensor check in the afc reads 2.8 with key on

 

ok i checked the voltage again. with the key in the on position its 2.8 in 2.8 out, when the car is running its .6in and .8 out does this seem right if i switch the wires around its 1.7 in 1.7 out
