just found this site, havent even had a chance to lurk yet
I am trying to change a mass air flow signal to the ecm, basically a quick way to lean out the fuel mixture, example would be a mass airflow sensor
@ cold start would send a postive voltage of 1.2 volts to the ecm, then it would drop to .92 - .90 volts after warm, i need to build a module that will always alow the basic cold start value of 1volt, after a cold start i need it to reduce the signal to half or one quarter the signal to the ecm. so if the mass air flow sensor is sending out 2volts i need this module to take that signal and reduse it to 1.2 volts. i would like to make the output value adjustable from 100% to say 25% from the input value, but it needs to be variable at all times only after 1volt.
cheers
