    the jaycar controllers run as an interupt to the afm signal, if you disconect the fuel controller it will run as standard, there should also be a switch on the side of the box that the controller plugs into which should turn of the fuel controller andreturn the system to standard. they are just a signal interupt system. basicly if you tell the computer that its getting more air through the afm than it it then it will give it more fuel...savvy??

    im bout to get one of these for my 4AGE they are good value and have great resolution for the price... i have a book on them if you need more info send me a PM
