Started planning the OMEX ECU installation today, starting with the Idle Air Control or bypass. The idle air control valve is located on the throttle bore (in most cases) and is designed to adjust engine air intake at idle which controls the engine idle speed. The PCM receives feedback data from various sensors to send output signals designed to adjust the air passage open or closed which adjusts the engine idle speed.
One thing that has vexed me is to where to actually install it, looking at many many…many forums there is very little information however I stumbled over a few images on an AK build site. Fortunately I have a 90° drill head and chose to mount the unit as far forward as practically possible – anticipating the need to run the heater hoses – and mounted with 2 M6 Rivnuts.
