Hi good peeps, I just turbo charging my 2.8 24v 4mo. Can I run the ignition and fuel with a stand alone as a piggy back bearing in mind the drive by wire, vvt and 4wd. The 4wd needs to be controlled by the oem ecu. The tps signal still needs to go to the ecu for the 4mo etc. The vvt need to be controlled by the stand alone ecu.
