the Map sensor wire enter to the SMC and supose to be modified and return to the ECU. I don't know if i have an other wire to the MAP sensor on a d16a6 1990??

Re:d16a6
 

Well, I am assuming the SMC controller is just put inline on your map sensor signal wire. 1 input and 1 output. Its pretty simple to read with a voltmeter/multimeter. You should have about 2.2v at idle or so before the controller and a much lower voltage on the output wire to the ECU.

Why not ask the guy you bought it from?

yeah i just send im email but i supose he don't take his mail for chrismas.

tomorow, i will try to take the voltage of the map sensor to the input and the output.

thanks a lot for the help :D
