Cobb vs UpRev
 

Ok so from what I can tell these are the two systems we can use to load our own Maps and mod our ECU. From the sounds of it the UpRev binds to the first ECU you use it on and that's it - you're done. Does anyone know if the Cobb unit is based on a licence system as well so that you can only use it on one vehicle? Seems very costly for what is basically an EEPROM programmer for your ECU.... especially if they are only allowing you to program a single vehicle with it.

Other than that what are the differences between these two systems?

Yes it is based on a "one car one handheld" Basis

And with my experience with the Access port on my 350Z dont get it use the Uprev



DAN

APs are super common in the stock boosted car world - like Evos and Stis have great success with em. I have one from my Evo that im waiting to get reprogrammed for the Z. It is much easier to use than the uprev and a lot of vendors are using it now.

So the Cobb system is for only one vehicle as well? If my friend has a CEL on his car I can't use my AP to clear it because its linked to my car?

Yes, the Cobb AP gets "married" to the vehicle and can't be used on another until it is "un-married" from the original vehicle.

UPREV you can tune the car yourself. Cobb you can not and must take it to a tuner.

NIzmoz isn't the AP tuneable?

CobbTuning.com - AccessTUNER Pro - Public Release

Again, YOU do not have access to the tuning software yourself. You must have a Pro Tuner do it for you. UPREV sells you the tuning software so you can do it yourself.

And UPREV tuning is way more powerful than Cobbs will ever be.

Can you elaborate on this? In what way is it more "powerful"?

With the Cobb unit can you raise the rev limit similar to that of a ECU Flash by Technosquare?

I am not sure about the 370Z, but with all years of the STi Cobb sells the tuning software so you can tune it your self. I would assume that they will make that available for the 370Z also. I would also like to know how UPREV is more "powerful" than Cobb?

I just want to make sure I'm following this all correctly so someone please correct me if I'm mistaken but:

Cobb makes 2 units. One that lets you just upload pre-made "canned" maps. The second one lets you upload the canned maps, OR have someone with the soft ware dyno tune/professionally tune the ECU. The Cobb also allows you to change maps on the fly, 15 seconds I thought I read, including a Valet Map?

UpRev is a unit that comes with software that you yourself can use to tune your ECU.

Technosquare - just reflashes the ECU with their map.

You can also get a dyno tune with UpRev.

Here's what I'm trying to figure out. If you're going to get a dyno tune, is one really better than the other? I mean, if you're planning to use the canned maps, then I can see how one might be better. But if you're going to have a tuner custom tune your car on the dyno anyway, then what difference does it make? All the software is doing at that point is giving the tuner an interface to the ECU and allow him to modify the parameters. Do one of these software packages give tuners access to some parameters that the other doesn't? If so, then that would make one better than the other. But if both of them give the tuner access and control to the exact same parameters, then I wouldn't think it'd make a difference in terms of being able to get better gains out of one over the other.

Thanks Semtex. I figured you could just have a pro do it instead of doing it yourself but yeah I don't know that I'd want to be screwing with tuning my own ECU. God forbid I leaned that **** all the way out.


BOOM!

I agree completely. I like, however, that the Cobb has a Valet setting. Wouldn't want some 16 year old blasting around, joy riding, in a $35k car with 300 at the wheels.

Well, there's a lot more to tuning than just tweaking the AFR. You can tweak the ignition timing, for example. But like I said in my previous post, I'm a little confused myself at this point. If you can get a dyno tune with both UpRev and Cobb, then is one really better than the other in terms of hp gain? I would think that the answer is no, as long as both give the tuner an equal amount of control and flexibility over all the pertinent parameters. I'm no expert on tuning though, so if I'm wrong, someone please jump in.

I actually talked to Sharif at Forged last week and gave him the green light to order in a Cobb unit for my Z so that he can dyno tune it. I want to make sure I'm not shooting myself in the foot. If I find out several months from now that Sharif would've been able to get even more hp out of my car had we used UpRev instead of Cobb for the tuning, I will not be a happy camper!

I suspect the guys at Forged would have mentioned that they could make more power on UpRev vs the Cobb if it were true.

Anyone know if either UpRev or Cobb can raise the Rev Limiter? 8K+ Rev Limit on a car seems like it would be fun. Although I'm used to my 15.5k Rev Limit, hahahah

You're right, there will be no performance difference between them if there is a dyno tune done. However, if Cobb does the same on the 370 as they did with the STi/Evo, you will be able to see A/F ratio, Coolant temps, 0-60 and 1/4 mile times, ect., along with lots of base maps, like economy mode, valet mode, race gas map, pump gas map, ect. Cobb was able to do all that on WRX's/STi's/Evo's, so I would imagine it will be the same with the 370Z.

Maybe UPREV and the others can do this stuff too, idk.

Togo, rev limiters, MPH limiters, and others are all built into the ECU and any simple tuner (canned or not) should be able to remove them if they know what they are doing. That is if you want them removed. Also, upRev also has Valet tunes and let you change tunes on the go with the cruise control buttons I believe.

Well, I just sent a note to Sharif to confirm that gains will be the same on both tools. I'll let you guys know what he says. Or maybe he'll find this thread and chime in. Also, if you look at Cobb's webpage for the 370Z, it looks like you get all those goodies like valet map, anti-theft map, etc. CobbTuning.com - '09 370Z AccessPORT

@theDreamer - Tune changes on the fly with CC buttons is sweetness! Thats beyond sweetness, it's sweetesque!

Don't mind me, I'm easily amused...

In the end I believe most tunes are really all going to be the same if you get a dyno tune (Uprev or Cobb). Each might have an "extra" feature that you like, but really it comes down to which one you can get best access to with the best support. Uprev is in Austin and I can easily drive to them and have them look at my car and such. I bet Sharif will do a great job with Semtex's car with Cobb.

Would it be possible to get the Live Data function of the Cobb unit displayed onto a dedicated screen or the Navi screen, kinda like Magden or HKS Camp II?

Depends on how the data is transferred and how quickly it reads it (delay?). The data might log every second but it might not be able to display it in real time which would make it useless, though I am completely unsure.

From what I've heard, the AP doesnt have the same features for the Z as it does for Evos and STIs. It seems that the tuning software of choice for the Z world is Osiris from UpRev...

As far as suggesting that the average folk tune their own car... I would 100% advice against it. If you dont know exactly what you are doing, have someone who does tune your car...

Specially so in the Z, since it seems to have two maps overlayed rather than just one like we are used to...I'm scheduled for a tune as soon as it comes out, I will let you all know how it goes.

Osiris offers a valet mode as well. In fact, at least one g35 owner used the valet mode as a form of a two-step for launching at the drag strip. He basically selected the valet map, which I believe limited his revs to like 3k rpms, then when he launched, he selected the performance map. Viola! Two-step.

Another benefit from the UpRev offering is the Cipher software. Unbelievable software; you can log practically every sensor on the canbus** (not "literally" every sensor).

Also, just from observing the two product offerings on the g35/350z platform, I would suggest that over time/into the future, the Osiris product will offer more tuning parameters. I don't know if Osiris will ever allow for tuning the VVEL system, but if either company ever offers such functionality, it will likely be UpRev and not Cobb.

Search the other 350Z site and you will see the break down. Cobb can't adjust cam timings, UPREV can. There are many other things. There is a reason many big tuners are using UPREV now and not COBB and why many are switching from COBB to UPREV on the other site.

UPREV has 5 maps you can program into your CRUISE control button. You switch between them. VALET is one of them.

Cobb you need to hook up the device to switch maps.

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.

Many other posts to read about, just some examples.

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

http://my350 z.com/forum/tuning/422156-cobb-tuning-vs-osiris-tuning.html

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.
