Cobb vs UpRev

semtex · 07-10-2009, 12:41 PM

Are you talking about Osiris Pro where you do your own tuning? Or Osiris standard where you send them your data logs and they send you back an eTune? If you're talking about former, then it makes sense. Problem is not everyone knows how to do their own tuning (myself included). If you're talking about eTunes, I think I'd rather dyno tune than rely on the eTunes.

Semtex thanks for the long explanation there - I think I've finally got it sorted out in my head. I just like to know every little detail and figure out what the most bang for the buck is on mods, etc. Travel costs are definately part of the equation for me since I'm trying to figure out the total cost/peformance.

So that being said it sounds like a dyno tune is the only option with Uprev at this point since there is no e-tune available according to NIZMOZ...

semtex · 07-10-2009, 12:59 PM

Not even a dyno tune is available with UpRev yet. They haven't finished their development for the 370Z yet. The only thing available so far is dyno tune with Cobb.

NIZMOZ · 07-10-2009, 02:19 PM

I plan to go back up to UPREV in a few weeks again to have my car retuned. I just ordered my MotorDyne Shockwave Dual Exhaust so after that gets installed time for a retune.

Sorry, I was talking about the Pro. I didn't name it explicitly because I haven't paid attention to the various package names available.

I've wanted Cipher for a long time now; I just can't justify spending $400 for data logging. However, with it, I could street tune my current ride(I presently have a utec). That sounds really cool and would be an awesome learning experience. Plus, there's all kinds of little things I've wanted to log.

For example, I would like to log acceleration times in from say 40mph to 120mph in 4th gear. That would give me a fairly large area of rpm, in a sufficiently long gear. Then run the same rpm range in 3rd gear. 3rd gear is approximately 27% shorter than 4th gear. Then do something similar in 5th. 5th gear is about 27% taller than 4th. It would be interesting to plot acceleration in 3rd, 4th, and 5th against gear ratios.

Once one obtained a large enough sample set, one could start playing with final drive numbers, either through the FD ratio, or tire sizes, and make some decently educated guesses on how changes affected acceleration.

Also, I believe(but don't know for sure) Cipher can log the pitch and yaw sensors used by VDC. It would be interesting(purely as an academic exercise) to measure pitch and yaw on the car over a known section of road as you change suspension components or tire compounds.

As you can see, I would prefer the UpRev solution. There's all kinds of neat scientific/geeky things one can learn from its data logging capabilities. But I have the benefit of having an older platform where the product is available. If I owned a 370z at this moment, I would get the Cobb.

The AP can log up to 14 items.

Street tuning is an option but tough to get clean runs to log and tune properly, a load based dyno like the Mustang we have is great and then do street tune to check driveability but wide open throttle is easier on a dyno

IMO, rushing to get a product out early may be profitable but it's better to wait for a quality product. This one has been a miserable experience for G37 owners.

Which one?

Mr. C · 07-12-2009, 10:11 PM

a number of G37 owners who purchased the Cobb AccessPORT are far from satisfied.

With something like Cipher, one can log with ultra high precision how long it takes to accelerate between two given speeds in a given gear. Make some adjustments, and make another run. The cipher logs should be precise to the ~10 millisecond level.

I don't know what the logging capabilities are of the AP unit.

I'm not sure how pro-tuners are doing it with the nissans, but when I got my pro-tune for my suby with the accessport, it included the dyno tune first, then the street tune to smooth everything out afterwards. Makes more sense to do it this way because there's no way to get a good tune if you're only doing one or the other.

Yeap maybee 10hp gains from their can tunes

We're not talking about canned tunes. We're well past that in this thread. It has already been stated repeatedly that if you want to go with canned tunes, go with UpRev because Cobbs canned tunes suck -- it's a no-brainer. But you can dyno tune for Nissans with Cobb now. And once we start talking about dyno-tunes, it's basically a wash between Cobb and UpRev, the choice boiling down to preference in terms of having a standalone handheld unit and also cost.

Actually many didn't even get any gains. Many 350Z owners also are not satisfied and selling theirs.

Yeah, I wouldn't buy cobb for "can tune" unless they were knocking down 20whp. The only turn off for me on Rev is the license fee. Because I bounce from Z to Z. But cobb can tune sucks, I am stuck on this one, for me atleast.

You can remove the license from one car and put it on another car. We have customers that are on their third or forth car. Customers sell their licenses all the time to other customers also.
