Uprev problems?
 

My osiris tuner tried to dyno tune my car today... For some reason he can't reflash my ecu... Anyone know why? He has tuned other 370z's before but my ecu just wasn't accepting the changes... No matter what he does or what changes he makes, it's just not doing anything different.

The previous 370Z's, were any of them 2010's? I know Cobb did not have any support for 2010's before they pulled the plug.

yeah he's tuned other 2010's before. And this morning he just downloaded all the most updated software to ensure it's compatible......

Could be a bad data cable or you had an accessory on when he was trying to flash.

cable was good he just tuned a 350z 30 minutes before me. All accessories were off...

looks as your going to have to wait till Uprev opens tomorrow.

Not being a hater, but why do owners get the uprev tune anyways? From some of the results on here, it's not even worth the price tag of $500+.

For the simple reason that most are trying to get the most out a na motor?
With all the bolt ons a tune makes a difference, and besides you get 5 maps and the torue gets bumped up a little for a seat of the pants feel and a definite Dyno power gain. $550 ain't cheap but but neither is sc? :tiphat:



Op I hope they get it resolved and you get to see why people pay the money

it changes the feel and response of the car, it optimizes your mods, the maps, it fixes the throttle lag, ...basically, have you ever had those days where you car really feels good and pulls nice all over....well a tune gives that everyday....a tune can make a world of difference

I agree that a tune can make a car feel so much more powerful. I had my 08 Civic Si tuned with Hondata Flashpro and I felt a good amount of power midrange as it lowers vtec engagement to 4k rpm and raises redline to 8.6k rpm. The Flashpro also enables launch control limiter. It also fixed the rev hang issue in the Si.

Can someone explain exactly what the uprev tune modifies for the 370z?

UpRev - Engine Management check it out man...good reading

Thanks GZ3 :tiphat:

Osiris Standard
Osiris Standard includes Cipher and utilizes the Cipher cable to reflash and communicate with the vehicle through the OBDII Diag Port. Osiris Standard also includes Map Switching allowing you to use different tunes for different situations and 3 eTune updates you can use at any time.

Osiris Standard is a licensed based system meaning your license will be transferred to the first ECU that is flashed. This vehicle can then be flashed as many times as the user wants, but the flash will not work on any different vehicles. One additional license can be purchased at a discount for enthusiasts that may have more than one vehicle, contact us for details.

Parameters that we will tune include:

Up to 5 Maps on cruise control equipped vehicles
Idle RPM
Speed Limiter
Electronic Throttle Control to achieve Wide Open Throttle at all speeds.
Rev Limiter
DTC disable
AFR Targets
Fuel Compensation
Ignition Timing Advance
Cam Phasing for equipped vehicles.

Kinda a disappointment for $550 + tune + your time.

:tup:

Because I was bored on a Saturday afternoon. Also I'm not paying $500 or even close to that.

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?

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

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. :tup:

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 :tiphat:

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.

does Hypertech have one for you guys?

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.

How much? PM me where you got it done too! Might be worth a road trip....

It's all about the sound for me!

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

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? :D

:rofl2:
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.

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.

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?

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.

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?

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.

It's good to know our cars still run spot on A/F with a couple/ several mods. My 350 was the same till I ran headers.

I still remember when VTEC for the integras first came out. Everyone was waiting for a way to manipulate the VTEC. It eventually happened.:tup:

I feel you though. That's pretty much my plan on tuning my Z.

I gained 20whp peak whp and anywhere from 15-25whp throughout the powerband JUST from an Uprev tune. My AFR's went from ~14.5 before tune to ~13 after tune. A 14.5:1 AF ratio is pretty lean and is not good in the long term.
and FYI, $500 includes 3 different E-tunes from Uprev.

OP, your tuner probably knows this already but make sure your ECU code has already been cracked by Uprev. If not, you'll have to do an ECU ROM dump and send the files to Uprev and wait till they crack the code. Luckily my ECU part number was already cracked so I was able to reflash my ECU instantly.

Sorry to jack thread but how the hell can you compare a 370z to a Civic SI...?
lol!
Tune benefits the car in every single aspect.
Except for voiding your warranty. lol.
You will definetly feel a difference with a tune and it's convient to have because of the 5 maps you choose from.

I wasn't comparing the car. I was comparing the results of a tune. A Hondata base map tune made a car with similar modifications perform totally different, as you can see in the video. I was asking if a tune for the 370z would result in that much of a difference to be worthy of an owner's $550+.

How can you compare the results of a tune from two different types of cars Uprev works on Z's and is good. I had it on my 350z both NA and supercharged and I have seen the difference of before and after on 2 370z's that are NA I am also about to put it on my 370z that will be boosted.

To you it might not make sense but lets be real here how much can you really say if you have no experience with it at all.

This is about my same results (A/F) I had on my 350. But only about half the HP gains. Of course my 350 wasn't the rev up model either. But I do believe the 370 compustats for mods alot better than our 350's a G35's.

What's the reasoning behind Nissan having different ECU part numbers? I could understand between base models and the Nismo.

My G35 is a VQ35HR sedan so yeah. I agree, the VHR ECU's seem to do better when it comes to bolt on mods in terms of stock tuning. DE's and HR's seem to go lean pretty quickly.

Hypertech does have a unit available for the 370z. It is called the Power Programmer. They claim:

Performance Gains
Premium Octane : + 6 HP @ 6850 rpm, + 10 Ft-Lbs @ 2450 rpm

Check it out through the link below. The unit also allows you to flash back to stock whenever you want. Some forum vendors offer this for around $350-$400.

Performance is our Passion - Hypertech

What does UpRev raise the redline to in the Z? One member said his tuner set it at 7750, another at 8000...
