Gas Pedal Delay

Is that done just with UpRev or some kind of tune?

Check your oil temperature. Sounds like you might be going into "limp" mode. Mine has the same problem when my oil hits 220 or so. I also stall out if I let out on the clutch at my normal speed.

Say what?

OK....the throttle plates close on the 370Z under what conditions??

I was under the impression that the ONLY time they closed was at idle and during deceleration. That's what VVEL is all about I thought. Throttle plates remain WIDE OPEN all the time and the amount of air getting into the cylinders is controlled by the VVEL, hence no real need for throttle plates (other than for emissions).

My 6-spd S/P has never had these symptoms. I noticed a delay in power only when the slip light illuminates because it detects slip. Otherwise, mash it to the floor in any gear and it instantly goes.

Yeah, when oil temp gets just above 220, I start to lose throttle response. So I guess it's not a full limp mode; but there is a NOTICEABLE lag between when the pedal goes down and when the engine responds. At lower temps its just fine.
I was going down the road and a 'stang wanted to go. Took him from 2 moving starts, but as soon as we got to a red light, my oil was already over 240. I knew it was over at that point. I didn't stand a chance.

Sounds to me more like self induced limp mode, so to speak.

IcedZ

Definitely not. I had somebody else drive it until it hit 220, then had him drive it hard for a couple runs. He was shocked. Then he was doubly shocked when I told him to look at the oil temp gauge. He's a Ford Mechanic.

Yea I hate the electronic throttle on the 370Z, first gear especially can be herky jerky with the lag delay...the 350 had much more direct throttle response. So this can be reprogrammed via AccessPort?

I tuned it with COBB. Don't know if you can do it or not with UpRev.

I get this after I floor it and then come to a stop and try to accelerate again. Almost as if the car's going to stall. Strangest thing. It goes away after a bit like the computer is resetting or something.

Very frustrating to say the least.

No, the ECU tune to improve throttle response doesn't fix this (I have the tune). It fixes throttle response alright which is a must in this car however that's a whole different thing.

Very frustrating... did I already say that?

Edit: for some reason at the track under massive constant throttle I don't get this. Hrmmmm...

I installed a Sprint Booster....love it....

???

I called the company and they said there was a problem with the Sprint Booster for the 370Z. Declined me placing an order. Did they fix that issue?

When did you check with them? This is news to me....I have no problem it that I'm aware of...I'm going to have to call them

I just read a post today about a spirtbooster. From what I saw it increases throttle response. website was like spirtboostersales.com i think it was like $350. may want to look into it, im going to.....
