what do i do with the yellow and white wire? i know i dont use the pink,purple and blue wire. And also my vafc cant keep memory help, thanks man

 

yellow and white are the most important wires. They are the map sensor input and output wires. Lemme check my car to make sure I'm giving you the right info. White is map input to the apexi, Yellow is map output from the apexi to the ECU.
Cut the White/Yellow wire going to the ECU, that's the map signal. the White/yellow from the chassis hooks into the white, yellow goes into the white/yellow to the ECU.

 

the memory works after a couple hours but what wire does the white and yellow go to on my ls? everything is working fine now and just curious if its needed.

 

anyone help?sometimes the memory goes away why?

 

yellow wirse is the airflow/pressure signal out....the white wire is airflow/ pressure signal in

 

on the ecu the yellow/white wire is the map signal?

 

you might have taped into the wrong power wire in the ecu..

 

Is the Pressure signal and map signal the same?
