100% throttle not possible?

Hey, I've been recording my HKS:iS' readouts on my DDIN to see what it's reading out and I noticed two things.

A. I can't go over the high 70's% in throttle.

B. these things need a higher tolerence for airflow lol.


But A. is where my concern is at- if that's something that might actually be holding me back? maybe the traction control at some level is retarding me. Because, I'm not a math expert but 20% more throttle could be a good thing.

Or do you think the iS is just stupid.?

I think it's supposed to go higher than that, and then towards redline it starts to close anticipating the shift... I'll look at mine tonight when I take her out...

Are you sure the TP sensor is calibrated right? Try removing your floor mat and really jam your foot and see if makes a difference.

take your piping off and press on the pedal to see if the TB opens all the way up. (with the motor not running, of course.)

I do believe that the OEM throttle body should open to 95% or so. The throttle body is like a butterfly valve and the last few % won't make a big difference on air flow.

Thanks for that chart- I think I will check out the throttle body. I'm going to keep my eye on this.. maybe get a new, bigger TB =D

I know thats a big upgrade on the SRT8 jeeps, but I don't know anyone that makes TBs for the G...?

Go ahead and call up japtrix- I'm sure roger can teach you a few things.
One of the nicest guys I've met. You could probably at least learn a few things there. I really don't see a reason to troll my threads because I hate your convertable G35. Real professional.

I think I'll keep my racing on the track though- thank you.
Your car sounded cute when you pulled up that day at the gas station

I checked the TB- It's definitely opening enough to not really be an issue as far as I can tell- I apprecaite the useful input.

Does that actually work? I mean, it's not cable driven. So the TB shouldn't be actuated, correct?

If the ignition is on (but the motor not running) the throttle body will move.
