They are working on completing the software but the VVEL system is adjustable in the UPREV tune last I heard.

Uprev/Osiris/Cipher is a real tune from real people, not a pre-programmed gameboy. Also you get a copy of Cipher which pays for itself after the tune, its a complete diagnostic program for Nissan cars.

The only thing I see about the UPrev is I will proabably e'ing mess up my car trying to self tune. Umm.. I wonder what happens if I do this. uh oh

You can have any of their tuners do it for you. Or get their E-Tunes that are pre-tuned to your car once they have them.

It works the same as Cobb for tuning but you can get the software to tune it yourself, and also get a full diagnostic logging software with it as part of the package.

I'm a little confused.

UpRev comes with canned tunes like Cobb. However, UpRev allows you (or someone else) to fine tune your ECU through various parameters using their Osirus software? Not only that, you can data log your car using Osiris and send a file to UpRev to "tweak" to get more power?

From Cobb's website

Datalogging - Onboard datalogging allows multiple channels of data to be recorded simultaneously for later review. This allows for analysis of current engine performance. Datalogs can be sent to professional tuners to provide additional power gains remotely through email!

You can data log your car with Cipher. Which is part of the package. Any mods in the future you get as well you log your car, send them the logs, they update your map and email it to you for a small charge.

Pretty much what you said.

Again it doesn't log near the amount Cipher does. Please review it on the other 350z site. You can monitor your car in real time right when you are driving. You can't do that with Cobb either.

So Nizmoz, even if one were getting a full dyno tune, would it be your opinion that one would be better off with UpRev? i.e., a dyno tune with UpRev will yield better results than a dyno tune with Cobb Pro-Tune?

That is good news. Essentially, they can see how the mods are affecting the car as I drive and fine tune it for more power.

Just spoke to Sharif. He says that the parameters you can modify with Cobb and UpRev are identical, at least as it pertains to an NA car. He said there are three main ones relevant to tuning an NA car -- AFR, cam phasing, and ignition timing, and all three of those are tunable via Cobb software for dyno tuning. He also said he'd chime in on this thread to help clear up any confusion.

Edit: removed what I said here, in light of semtex's simul-post above

To me the cruise control thing is a pretty key feature too, although maybe it isn't for everyone. Being able to swap out 5 different maps instantly from the steering wheel is nice (think of the uses aside from your standard "aggressive tune for premium pump gas": 1 or more different race gas tunes for what's available at tracks you frequent, a valet mode tune, a fuel efficient / mild tune, etc).

I maybe a little biased towards UPREV, but I have also seen what people have said on the other versions like Cobb. Many have switched to UPREV from Cobb due to things they didn't like about it. I just don't want to see anyone spend so much money on Cobb right now as you can go with the better one right off the bat.

Cobb is better for the Scooby guys. It just doesn't work as good in Nissan's as people wish to believe and UPREV does. But it is your choice and I just want you to make a good decision or whoever it is on which to get. I try to point out things, but it has been hashed out so much on the other site that you can just search it and find them.

Okay so what are the cost diffeneces?
Cobb- $695
Uprev -$1250

And they do the same for N/A cars as Semtex stated above. Would this be correct. Both have data logging and can send in for fine tuning via email. I don't know why I would spen double the price just to change maps from my crusie control...please correct me if I am wrong on these pricing. I am very axnious to get one of these, but just want to get all the facts straight.

Yep, and I appreciate your efforts at not wanting people to waste their money. I very much appreciate that. The way I put it to Sharif is that, bottom line, I don't want to tune now with Cobb only to find out several months from now that I could have gotten another 10 whp with UpRev! But he assures me that that won't happen. Now, he did qualify that by saying 'for a NA car'. In other words, I'm lead to believe that if you go FI, then UpRev does indeed have an advantage over Cobb. But maybe Sharif can fill in some more details for us later.

Good discussions going on here.

I have been reviewing Cobb's technical bulletins and the AP tuning offers everything except for Cam phasing/lift control. The VVEL system is very sophisticated, and it's going to be a while before tuners have full understsanding and control over this. It's important to make the distinction between Camshaft Phasing (also called camshaft timing control), and Camshaft lift control. As a side note, the vast majority of power gains come from fuel and IGNITION timing enhancements, rather than cam phasing and lift contorl. We tune cam phasing on the VQ35's with haltech, and it's easy to see that the OEM mapping got this one pretty right. On the intake side, at WOT, we run from full advance, to full retard by redline. There isn't much more room for refinement there.

We are ProTuners for both Cobb and UpRev, and have quite a bit of experience with both of them, so if anyone has any questions, feel free to ask. I think we are one of the few Nissan based shops that has hands on experience tuning the Cobb AP, which we've done with the GT-R, and also the EvoX.
