Under $2500 Tubo Kit Update 2

[saplaymate]

[QUOTE=cdydjded;133318]Well I spent all weekend figuring out the wiring for the AEM FIC. Not that it takes that long to install but I was trying to find the easiest way to install it. I found the injector, cam sensor, crank sensor, switch power & ground. I still need the TPS signal & O2 signal. If anyone can help I would apriciate it. The manifold is done, turbo & I/C is on the way & the oil pan is getting modified for the oil return. Any questions please ask.

I'm a little confused on the wiring set up for the FIC, but I've never seen one or read it's instructions. The wiring may explain why others have had problems

First by O2 you mean A/F sensor, correct.

But I don't understand tapping into the injector or TPS signals?

On our cars fuel injection duration is controlled by the MAF input signal, so all that needs to be done is manipulate it and you can directly control injector pulse width. (I don't see why you couldn't do the same to the injectors signals)

Tuning injector pulse width in closed loop trims and open loop is simply modifying the MAF signal for the corresponding pressure & RPM. I know I've done it and researched Toyota's training junk.
