Computer Calibration after FI

Joe Go · 08-19-2012, 09:24 PM

Can any of the aftermarket tuners adjust tire size, turn off traction control, change rear gear ratio and calibrate the fuel milage reading after an injector size change? Forced induction is in my future, but I'd like to make the car function like stock.

After an injector size change? I'm confused at what your trying to do or say?

Ok it's not just me

I read it like 10 times to make sure I was not losing my mind. OP you may have miss typed.

The computer tells me how many miles to empty currently. After changing the injectors would the reading be incorrect?

Hmmm not sure. Probably a question you should post on one of the FI threads. Those numbers are more of an estimate anyway.

Yes the miles to empty is scewed allot,and I have the tuner version of Uprev and none of these things are adjustable,I just live with it,it's really no big deal.

No, none of that is available.
For those wondering, the injector change alters fuel input and the computer (which outputs MPG) does not account for this change so it throws off MPG. Also, this is different than the ECU, there is a separate computer which controls the left display which reads the MPG, miles to empty, outside temp, etc.

I havent seen that functionality in anything available for the z.

I sent UpRev an email about the gear ratio / tire size stuff, you'd think that would be a pretty basic mod for any ECU, but no response. You'd think if it was easy they would've included it by now though, it's been a few years...
