The beta software at least works with the 1EA4B 2010 ECU, not sure if there is more than one.

The AP works on my 09 with the beta software

The only way to know is to try. Nissan has so many different version that its very hard to know without trying.

I just had my local shop call Cobb for me while I was at work. If I buy the AccessPort directly through Cobb I'll be eligible for a full refund if the AP doesn't pair to the ECU correctly. I'll call them directly today for further details. I don't want to go through Cobb as they weren't able to crack VVEL, but so far there is no other alternative to going back to a fully stock tune with the other methods.

UpRev, Technosquare, etc. will all leave their tunes on the stock ECU and can be found if the dealer does a thorough enough check. Basically if there's a major warranty issue that comes up they'll find the aftermarket tune.

Pretty sure if you get the cable/software from Uprev you can do the same sort of uninstall you can do with Cobb.

^^^can someone confirm this please.

Their FAQ says technically you can, but you need to consult them first. So I'm assuming that it's a little more technical than just reverting back to a stock tune with the AP.

I agree it seems they had a side dish of fail come along with their VVEL dinner. Besides, the corporate jargon at the beginning basically means they are not getting return on their invested time and/or are having financial woes in those areas and have to cut the specified product lines. Uprev with an actual dyno tune and forget about the AP I say. :p

Ive edited this post because i dont want to sound like im bashing Cobb. to this day we even use the first V1 AP on our 500whp STI. and i personally bought the V2 AP for my Suby. I did have problems with my V2 AP and had to send it back to them for reprograming... but still gave them good reviews.

Cobb, its sad you couldnt come through i mean lets set all the other features aside. We all know and you know everyone buys the AP for one reason only. the basic OTS maps.....

On another side note. 2 months ago i personally called Cobb about OTS maps and who ever i talked to was very short, didnt seem to care about my questions just overall didnt want to talk.... Its all about customer service.

:"(

Well I ended up getting a good deal and bought one used. It's pretty nifty and I guess Cobb support doesn't matter. They were never going to make maps for it anyways, but if you have access to a shop like AAM that will use it to tune it's all good.

Uprev just told me that cracking the \vvel is a top priority with them and they are planning to purchase a G37 or 370Z in the next 4-6 weeks for testing.

I think Imma go with uprev!

Cool :tup:

Sick. I have heard nothing but good stuff with uprev. After the exhaust and LTH's an Uprev tune will be next.

If they can they will have a huge monopoly on the tuning side of the house.

huh? the thread right above this said someone there talked to uprev and they basically said its not worth the risk/reward..

Do you have an email or something confirming this?
Because the last message I got was no they are not doing it currently, time for me to shoot them another email.

*gets on knees and prays* Jesus please send Haltech to save us all..:bowrofl:

amen!!

if any company can crack the vvel... they are gonna have some serious business....

only if it makes more power.

I was thinking the same thing...Why does everyone think it will make more power? I can see if you went with aftermarket cams or other headwork but otherwise I doubt it would make much. Nissan knows what they are doing.

Everyone always said the same thing with Honda's. People wanted chipped ECU's with a lower/higher VTEC engagement RPM, but they usually lost power. They would lose so much midrange that when VTEC engaged, it gave the feeling of gains but actually it was the opposite.

IMO it's really only beneficial to boosted setups where people would like to gain spool by retarding exhaust some and advancing intake as well.

Nissan also has emissions and MPG to juggle -- even N/A valve timing may not be optimized for best power.

It all depends on how much air you are flowing...

Add better intakes (especially with FI) and higher lift earlier in the rev range may make gains; speaking of FI, turbos are exhaust restrictions, so playing with cam phasing may indeed help spool up and make more power too.

I have a good bit of experience tuning VVTLi on Toyotas, and there is definitely potential power to gained from adjusting valve timing and lift.

All true.

I think the general point is that this 3.7 V6 is already tuned to 332 bhp from the factory, which is near 100% volumetric efficiency. Not much to gain beyond 105% VE or so.

Yeah, for a totally stock set-up the gains may be minimal -- although no way to know for sure until we can tune it ;)

Is it just me or are you people not realizing that the AccessPORT can also be utilized to capture ECU versions. You could take it to a tuner who then would backup the OE Flash and the Tune Flash onto the AccessPORT.

From what I'm reading is that COBB is no longer gonna waste their R&D $$$$ on NA Platforms that do not get a larger cost2power ratio. But I don't believe it means that it no longers can take a bit4bit backup of an ECU...

Anyone that knows for sure if I'm incorrect, please correct me. :)
