Gas Pedal Delay

kenny's 370z

yes,it took 3 days for the cel to pop up.if i drive the car normal on the highway at 55 mph,my dots want to stay on the 3rd one.WAY too cool.i had read that the mishimoto also throws a cel ? let me know if it does even though i will most likely be getting one light be dammed.too much power to be gained wiTH lower coolant temps.

Mike

Yes it's fixable through tuning to have the throttle open quickly rather than delayed.

I have never used this personally but I have heard good reviews on it...One of the reviews came from one of our engineers who tried it out on his wife's BMW...

Not sure if it was adding the nst pulleys or the up rev tune but no delay anymore.

I have it on my 2010 370Z and love it....one of our members indicated that Sprint Booster was not working on the 370Z...not so..here's their #877-225-5577 ask for Steve or Shaun M and they will give the intel on this which is positive...MichaelM

it might have to do with the VVEL and the ECU. VVEL opens the intake valve wide open when you get on it allow for more air intake. mabye at such a low rpm it forces it to tun too lean flooding the cylinder with air until the ECU corrects and the injectors spray more fuel. mabye thats where the lag and sudden power is coming from and why its corrected when you tune. If you are going at a higher rpm there is more fuel being put into the cylinder and mabye thats why at higher rpm's (i.e. 3,500) there is nothing but power. I know when your MAF sensor is messed up that theres a lag when you get on it. the car runs too lean and there is a huge cut off at a certain rpm (3,000 rpm for me in scion tc). thats how it to me when this happens. My 2 cents and thoughts.

I've attached my email to them from back in February. They must have fixed the problem they were having.

My complaint with the stock throttle is the delay. Sit with the car in neutral and quickly depress and release the accelerator. In a Ferrari, you'd get a very fast rev and decel. In our car, there is a huge lag on the rev, the car holds the max revs for a second or two, and then it slowly decels. Sure the flywheel has some role, but I suspect the digital throttle is a bigger culprit. Did the Sprint Booster help with this at all?

I may just buy one and exercise the 30 day money back guarantee if it doesn't help things.

Mike, can you elaborate on what you like about it and how it's improved things? My main issue that I'd like addressed is the slowness in throttle blips. If you sit in neutral and just blip the throttle, there is a huge delay in the revs building, then they hold for too long and slowly drop. My hope is the sprint booster addresses at least part of this issue.

This happens to me as well. At first I was turned off by it, but now, to lessen the effect of it, I accelerate slower. Though when I want to take off, I rev higher to get a quicker response.

What you are describing is what push me to install the sprint booster.
There are 3 positions with the sprint booster....stock...moderate and aggressive
you will notice and feel quite a difference.....let me know how it goes...Michaelm

I have this and it made a huge difference. Throttle response is now linear. While this can be fixed in a tune, using this makes adjustability much easier so I plan to keep mine even after I get it tuned

I thought the same thing until I actually had my car tuned. I turned it on once afterwards and felt it was useless at that point so about to sell it.

Shouldn't a tune take car of this? I get this too when I try to go from a low rpm in first or second gear... the car falls flat on its face before surging forward.

I have the exact same symptoms. Its very annoying.

You can recalibrate the throttle tables on your ECU to make your throttle response faster.

I did that, the car is alive now, and feels like a real sport car.
