So I'm about to try Autocross for the first time and I've been practicing my quick shifts

I noticed that I was able to shift faster than the Revs would fall. I was having to force the engine speed down with the clutch, which I don't like. So, I googled.

I learned all about the "Drive by Wire" and how it "hangs" for emissions and all that bologna.

I started searching for a solution and found some shiz by Technosquare but more importantly I read that a few people were commenting about their "much improved throttle response" from tunes (such as UpRev).

I'm posting this thread to get further confirmation from some people who have tuned their Z. Is this issue fixable via an UpRev tune? Will I get 100% control over my throttle body after a tune?

Thanks

 

The reason the revs fall slow is more due to the momentum of the weight of the heavy oem flywheel than actual throttle response.

getting an uprev tune would help it rev up faster by making the throttle more sensitive and also let the throttle body open up to 100% which would increase throttle response when revving it.

also the reason for quick shifting in the first place is to purposely shift it before the revs can fall so the speed is rev matched and you stay in the power band.

 

Thanks for your response. I'm not waiting for it to fall to idle rev. Just fall to the matched RPM for the next gear.

I found this just now. Maybe all that crap I was reading last night was posted by uninformed individuals. No surprise really, the amount of garbage information on teh interwebs is infinite.

 

An uprev tune WILL help the throttle response.

 

Take a look also at this...

U can turn off the ETC (electronic throttle control) in uprev which will probably eliminate the 'hang' you're speaking of. But yea I know what you're talking about -- it's a delayed decel fuel cut.

 

I believe Z1 was wrong here. The fuel cut delay is substantial. I have the JWT flywheel, lightweight pulleys and track wheels. No change in fuel cut delay.

 

Awesome. Thanks for posting. This is exactly what I was looking to hear.
