what kit are you getting?

[Black Yaris]

so they are running 7-8 psi safely on the 1nz in the scion's with stock internals

WE WILL my friend, WE WILL...

Question? Why did you end up choosing the AEM FIC instead of the more common/affordable e-manage? Any particular reason??

[cali yaris]

Because the eManage doesn't work. The stock ECU "learns" and compensates for any changes made by the eManage, at least from those who report actually trying it.

[CASTREX]

I thought that the learning issue would happen with any piggyback systems. Is confirmed that the AEM FIC will fool the learning feature of the ECU?

[cali yaris]

nope, not that I know of!

[Black Yaris]

Well I am going to buy a new clutch and lightened flywheel while I am at it, b4 I do the turbo

[Doc Zaius]

New clutch, definitely. I was talking to this mechanic at a speed shop about boosting the car, and he recommended *not* getting a lightened flywheel... said it would make it "not fun" to drive..? Perhaps with the spooling of the turbo, the engine would be smoother with the stock flywheel?

[smokinyaris]

yo cali keep me posted on your kit...................since ur in socal

[cali yaris]

will do -- suppose to be going in for coating next week, then shipped. I'll be doing a clutch also and probably the Kaaz LSD.

I do not see why it would make it not fun to drive

[Tapper]

I think the lightened flywheel would cause the clutch to engage different from stock. If you were to use an aftermarket clutch it would only affect it more. Also, the idle characteristics of the car can change.

[ddongbap]

A lighter flywheel would cause your revs to die down a bit quicker.

[Galavoxx]

Throttle response would be very twitchy depending on how light the flywheel is made. However, shaving a little weight off the stock flywheel will make a noticeable difference in engine braking as well as accelleration. As long as you don't lighten it up too much, throttle response should remain manageable. Talk to your machine shop and give them your projected crank HP numbers. After weighing the flywheel, they should have a suggestion for how much weight to take off depending on your application.

its not that it wouldn't make it as fun to drive. It basically can slow down how fast your turbo spools thus leaving you less rpms that you are actually making positive pressure. The reason being is because the heavier flywheel puts more load on the engine. More load on the engine = faster spool. Another example is the higher the gear the faster the spool. So if you are in 2nd and starts making boost at 3k rpm it will start even sooner in third because of more load on the engine. Lightened flywheels usually cater more to the n/a crowd.

[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.
