Uprev tune reviews

[suprspinner]

I am very interested in getting the Uprev tune but i have read both positive and negative comments about it, and even after searching through pages of topics i haven't been able to find a solid answer that could really help me. I'm just asking for reviews on the Uprev tune, the benefits the problems, if its even worth it...etc. on my car i have the Stillen hi-flow intake, the RL y-pipe, and the GReddy SE. Will the Uprev tune benefit me in any way?

What negative things have you heard about it? Do you have a CVT or MT?

I had my a local Nissan shop do an Uprev tune on my 3.5. There was an immediate and noticeable difference when I drove the car out of the shop. It feels to me a much smoother and quicker to wind up in the lower RPM's. Once I get past 4k the car just wants to keep going, I really feel it on the top end when pushing it out through the first few gears.

To me, it was worth the money. I feel as though after I have done all my bolt-on modifications that the car is responding to them properly now. The difference obviously feels less noticeable now that I have had it for a little while. We all get acclimated to a new mod to our car after sometime.

Just get it done. You wont regret it!

Mind sharing the cost of the tune? Both Uprev and your local shop.

[SHIFT_COUPE]

Sorry! I forgot to add that!

The Uprev Osiris Standard Tune is listed as $500 on their website. My shop here in CT did it for $425.

Here are a few other things that the Uprev tune can do. These depend on the tuner and whether or not the map for the ECU is performed.

- Speed Limiter
- Rev Limiter
- Idle RPM
- Wide Open Throttle at all speeds

Additionally, something I forgot to mention was that I have 3 tunes programmed into my ECU. One is the Uprev Tune, One is my shop's tune, and the last is a Valet tune. The valet tune restricts the speed and limits the rpms of the car. That way a valet can't mess with your car. These "modes" are changed through a combination of button presses on the steering wheel.

i have the CVT transmission, Did you go to RDZ Motorsports?

[SHIFT_COUPE]

RDZ, yes. Great guys! If you go, tell Scott or Rich that Tyler sent you.

Where are you located?

Btw, that price of $425 was a special over the holiday. Its probably more like $475 now.

[suprspinner]

its 499 at the moment but still not to bad for what it can do. do you still feel as if it has made your car perform better? i'm located in Westchester so its only a half hour drive or so. the only thing that worries me about the tune is the possible voiding of my warranty or a problem with my CVT but besides that it seems very beneficial as well as helpful with the valet mode and better MPG.

[SHIFT_COUPE]

I have certainly enjoyed the tune. The car feels alive to me again.

The warranty is nothing that you have to worry about. From what I'm told is the ECU flash is unrecognizable at the dealer. The guys at RDZ can tell you more about this than I can. I don't see there being a problem with the CVT, but I think you probably get more out of it on a manual transmission. The reason being that its difficult to manipulate the RPM's in the car when driving a CVT. I'm sure it will be great regardless. Give them a call and see what they thing about that.

Another thing that is great is if you don't like the tune for any reason, they will refund you and reflash the ECU back to normal. So what do you have to lose?

[suprspinner]

Thats very true, have they told you anything about a sprint booster?

[SHIFT_COUPE]

I was under the impression that the Sprint Booster does nothing. I don't see how something like that can do what it claims to do.

[suprspinner]

that's what i thought but, when i asked them what else i could do to my car that they recommended that's what they said. I think im going to get the uprev tune, you seem to love yours... with all your mods have you been able to clock a 0-60?

[BlackMamba08]

when you get the tune on the cvt... i would like to hear your opinion on it. keep this updated.

thanks.

[funkee]

I'm also interested in the results for the cvt

[Hussain]

I'm interested too

[funkee]

I'm going to hit up my local shop that does uprev for Zs tomorrow to see what experience they have tuning cvts.

The stock ECU manages the cvt well. Its not that a tuner can't be programmed for the cvt (the stock one does exactly that)... its just that the market isn't big enough for engineers to throw down and develop them. The returns just aren't there... yet.

I made a thread in Altima General about developing my own tune. I haven't gotten any replies. I just need a source code dump of the stock ECU ROM... or one of UpRev's or BD's and we can begin.

[suprspinner]

i sure will... i still worry that the CVT will have problems with the tune so ill be taking it slow for a little after i get the tune

[Ranga14]

It will probably be ok. Torque and heat are the CVT's enemies so just keep that in mind.

[suprspinner]

with the exhaust, intake, y-pipe i should be pushing near 270ft of torque, what is the limit for the CVT? will the sprint booster be bad for the CVT?

[funkee]

I contacted Rob at ZCar Garage in NorCal. He will talk to Jared at Uprev to see how many options we CVT owners have.

[Hussain]

NorCal? where do you live? I'm in Sacramento.... I saw your post in the altima general section and wish I could help but I don't know anything about developing software (and don't have access to the code from the ECU). good luck! keep us updated

[funkee]

I'm near San Jose. We're waiting to hear from UpRev before we begin an adventure. I'll keep you posted.

[BlackMamba08]

hope there's good news... although... i should probably pick up a y-pipe before any tune (if any) is gonna happen.

[funkee]

I just heard back from the shop guy, who spoke to UpRev. There is a ROM available for the Altima Coupe 3.5 SE CVT. The shop guy can't really set any expectations because we're getting into somewhat unknown territory, but he thinks there will be benefits.

The cost is going to be $625 out the door. It's $300 for the ROM, $250 for the flash and $75 for the dyno run.

He also says that he would need to flash the car back to stock, if we wanted to do that. Flashing it back to stock is not something I can do on my own - apparently. Also UpRev would provide the stock ROM. I can't dump it directly from the car. This makes me concerned, because I remember one of the members here had problems flashing their 07 Sedan back to stock and the car was out of commission for a bit.

It seems more expensive than I counted on - comparing this to the Bully Dog GT tuner. What do you guys think of the cost?

[mattyfo0z]

I'd say it's fair. It's a lot different than Bully Dog IMO, as you get to control what parts of the entire car you're tuning. With BD, it seems like you just get to +/- the fuel, ignition, etc without getting too in-depth which can be a drawback if your tuner is skilled and can squeeze out extra horsepower.

Do you mind mentioning what shop you got the prices from? When I get my taxes back, I'm picking up a y-pipe + custom exhaust then plan on getting my A/C tuned

^^ Yes. Rob is the owner at Z Car Garage. Chill guy and very willing to help the community learn the waters of the CVT tune. I talked to Rob, who in turn talked to Jared at UpRev; there are ROMs for the 2008 Altima Coupe 3.5 CVT, among others.

I didn't ask specifically, but I believe it is available based on this document: https://docs.google.com/spreadsheet/pub ... output=pdf

I talked to Ricko and Importroller earlier this evening about the UpRev tune. They assured me that significant benefits won't be realized from the tune until you get some bolt-on performance mods: such as an intake and new exhaust piping (headers, y-pipe, exhaust). Unfortunately, being in California - this means sneaking around smog laws. I'm not so excited about that.

From what I understand, there is a single ROM for each model-year, engine, and transmission. The ROMs are standard, unless you pay for a custom tune. I guess that means you can flash before you get the performance mods, since the ROM isn't going to be updated after you upgrade your vehicle.

[BamaCoupe]

There is a guy in a local car club I'm in (mostly Z guys) that has UpRev Cipher and said he could install it for anyone with any 02-08 Nissan or Infiniti for dirt cheap; does that sound right, and also is it worth it considering I have no performance mod's?

[funkee]

^^ Anything can be done with enough knowledge. But I don't think that guy knows what he's talking about, or you're going to get scammed.

You can download Cipher and Osiris for free: http://uprev.com/support.php. But it doesn't mean you can use it to flash any car that you want.

You can't use the UpRev cable without a license, and a license can only be used on one vehicle. The cable itself encrypts/decrypts the ROMs, so if you dump the ECU with their cable, you won't be able to read it or use any other cable to flash it. You also can't use the same cable to flash it because of the license issue.

However, you can use any old Consult cable and freeware software to dump someone's ECU and flash it to another car. The ROM on the ECU is not actually encrypted, but you need some in depth knowledge of Nissan's ECU to be able to customize it yourself. And in reality, if you dump an UpRev flashed ECU, you can only flash it to the same exact model-year.

There's a member on this forum called Importroller. He went to an authorized UpRev dealer to flash his 07 Altima. The ROM used was actually intended for an 08. There were no 07s available. There were some important differences, and the system's fail-safe should have prevented it from flashing in the first place. But because the headers in the ROM file were acceptable, it flashed anyway. The ROM wouldn't work on his 07 and the car was dead until he got a stock ROM from UpRev and flashed back.

If the guy at the car club manages to flash your car, but you end up with a brick, I doubt he's going to be able to flash you back to stock.
