Uprev problems?

TongMan · 01-30-2011, 12:34 PM

I think that many people get a CAI and catback exhaust for the brand, looks, and the sound. Some may get them for the the primary reason of performance. The uprev tune really gives nothing worthwhile in return compared with the Hondata Flashpro for instance. Just for reference, here is a video of a Civic Si I/H/E vs a Civic Si I/H/E/Flashpro. Can the uprev do this?

You've made it clear you don't see its worth it, and I respect that.
Not everyone is going to agree on every topic in here? So will leave it at that and move on. Have a Great Day

True that. Well worth IMO. Especially getting the A/F back to the correct ratio after mods.

I am looking for a tuning solution for the 370z and it appeared that the uprev tune is the only solution right now. I guess I will wait.

What's missing right now is the ability to tune VVEL (no system can control that at the moment) -- with that, I think we'll see even better gains out of tuning.

Anyway, completely different platforms, so apples and oranges.

It's the same reason people buy intakes. Hell you'll be lucky if they add 3-4hp for short rams, but yet people pay $300-$500 of them. Why?

It's all about the sound for me!

And exhausts...you'll be lucky if you get 5-10hp from them, but yet people are paying $1k - $2500 for them. Why?

Sound rules again. Performance is noticeable, but the sound is what sold me.

So for the 10-15whp we gain from an uprev tune, I think even the retail price of $500 is quite worth it.

And the bottom line is, because $500 can be a lot of money or chump change for different folks. It's what's worth it to THEM that matters.

And for the peace of mind knowing that you are not damaging your engine by having changed the entire breathing apparatus of your car!

The question is...what's 9HP and 5 lb/ft worth?

That video proves nothing, show me dyno graphs, were the mods exactly the same minus the flashpro, one drive better than another. The list goes on & on why that video is horrible.

Uprev can do a lot already with the 370z, not sure why lately people have been expecting it to do more. The Z is fairly well tuned from factory, throwing on bolt ons has shown no real need for a tune unless you want to bring your AFR back if it went crazy. Not everything is about HP/TQ.

Endgame · 02-04-2011, 03:58 PM

The Uprev tune makes the most out of the mods you have. Most guys with the Uprev tune already had intake and exhaust mods; the Uprev tuned still gained 10 -15 HP over that. Also, Uprev added torque back to the low to mid range, and it ensures you A/F ratios are good. That is great for me now.

I will be getting ANOTHER tune when/if the VVEL is cracked.

SPOHN · 02-04-2011, 09:30 PM

I'm up in the air right now with the Uprev. I don't mind at all forking the dough out on it. And there's no doubt it can help. But all the research I've done lately, I don't see where it's helping to much. Even in the A/F ratio department. I'm only referring to mods such as CAI, TP's, and CBE.

98intrique (member here) only netted 3hp and the A/F ratio was the same across the board. He had tested three different scenarios. Even had added a manifold on top of all the other three breather mods. Even Josh from Stillen said there should be no issues with just three breather mods, but a fourth would throw A/F off.

Now without going into detail I'm aware of the other purposes of the Uprev such as throttle response and such. Just don't know what I'm going to do. Knowing me I'll get it just so there's no issues. I'll probably install my mods, have them dyno'd and go from there. What do you think?

djpathfinder · 02-04-2011, 09:41 PM

That's right, don't expect much more gains in the upper RPM range, but expect improvements in the low to mid-RPM range, where we do most of our driving...that's what people are reporting and dyno charts are showing. Optimizing A/F ratio is the other big bonus. The other previously mentioned features are minor bonuses. The Uprev tune is good to have whether or not someone intends to do forced induction in the future.

djpathfinder · 02-04-2011, 09:42 PM

Nitrouz, did you go back to your tuner to try again, or are you taking a drive to Seattle and giving it a shot there at some point in time?

Jordo! · 02-04-2011, 11:55 PM

Guys, don't forget that peak gains may be minimal, but gains throughout the powerband may be more substantial.

Check out my dyno thread, I picked up as much as 10 lb-ft of wtq down low, which is a big gain, especially considering the motor makes a good bit less torque than power.

That's AFTER all other gains from bolt on's too.

nah...we checked my baseline A/F and everything is still spot on. Already gained 40rwhp from intake, exhaust and test pipes. My tuner saw the logs and said there won't be much to be gained from a tune. So I'm running the stock tune for now until I go FI. Might end up running an Fcon or Haltech anyways.
