Hey guys after abit of knowledge looking at puting a full wire in G4 xtreme In an evo 4. Im gona run a aftermarket throttle body without a stepper motor do i need to run anything else other then TPS, cam and crank sensors so that it idles correctly etc ?? also I have 2 wires from my alternator to my factory ecu and cannot find any mention of what to do with these?? and are the wide band sensors O2 sensors better to use? if so where is the best place to fit for optium readings.. Any help with these little issues i face would be great guys...

It will be able to idle but you will be missing idle up for cold starts and loads on the engine like AC power steering  etc.

The wires from the alternator give feedback to the ECU about the load and allows better idle control. We don't use these.

Wideband is almost a must have these days and should be situated about a meter after the turbo. At the very least make sure you have a fitting for one so that the tuner can fit one if required.

Ok thanks simon so i would assume then i also dont need to wire up the power steering pressure sensor either then?? and would have to decide if the gains of running a larger throttle body outways loosing the functions mentioned (cold start etc) or not...

Also simon i understand if i use a wide band 02 sensor i can not run this directly to the ecu??

If purchasing the sensor threw yous does this come with the controller required or is that an additional requirement as i cant find any mention of one on your site... Thanks again simon...
