Juicinjake,

Thanks for the info. We hope you get that Uprev cable/license soon. =). Check with Seymore4 here if you are ready to buy an Uprev. He is an Uprev pro tuner /Etuner and also sells Uprev. He could give you a better pricing.

Just so you know, I do not have throttle lag using one of my Modified wstar MAPs(AWGD).
As long as the RPM is at 2K and up, the power is instant. It does feel like a throttle cable, which shows on that initial very steep curve I made that start at 25% flow potential. (Pls. See V1H posted Line Graph) . The throttle is responsive once you hit 1/4 pedal push.
Also, I made less aggressive throttle opening on RPM's that is less than 2K. I realized why would I make the throttle open early when the car is cruising or idling? (Such a waste of gas.... More air more gas to mix)

My car does not have a close gearing ratio like the G37 , so I needed an aggressive throttle at lower RPM band, but if my MAP is too aggressive for the G37 at lower RPM, all you need to do is put that steep curve at around 50% flow potential. This way, the pedal gets heavier and responsive at close to 1/2 pedal push. This is good for tracking/racing, but not my preference for DD. My ideal setup for street use is a good throttle response start at 2K for off the line roll. My VQ35HR is a slug from stoplight until it reach 3k RPM. This is just a normal roll from the stoplight. I noticed a corolla seems to have a better pickup on initial roll with less effort than my HR engine... =) I have driven some loaner G37 sedan before and I know how close the gearing ratio on the first 3 or 4 gears. I hated it at first since it took a nano second to shift from 1st to 2nd. LOL! But I love the 3rd gear on that car.

I hope you can go back using Uprev and chime in here with your expertise...
