In still on the fence of going to my local tuner with uprev and may go that route it's just now your putting all your trust in one person and you not fully knowing what they are doing to your car puts me a little on edge. Have to remember Nissan employs a team of engineers putting in a lot of hours to program these ECM to cover all conditions and variables so you don't run into weird drivability issues under any conditions and also make sure the engine last.

What typically gets done on the Uprev if you wanted to keep it mild and reliable.

Any reason why you don't want to use EcuTek? It's generally considered to be better software, especially with the ability to tune VVEL, throttle tables, and traction control. I originally had my car tuned by Seb @ SpecialtyZ, but Rob @ ZCarGarage in San Jose is now doing EcuTek as well.

As for what to look out for in terms of longevity: make sure it's tuned for California 91 pump gas and don't touch the redline. These engines have oiling issues at high-rpm and you don't want to risk it.

Rob is the guy I am actually looking to go to since I live in San Jose. Last I spoke he is starting to use ecutek more but I got the impression he likes it more on the forced induction stuff.

Tweaking he vvel is one of those things that I am not so sure I want done as that is a very complex system and is just now starting to be tweaked and not having really seen the long term effects of it yet. This is my daily driver and I tend to keep my cars for a long time (this is only my second car after 16 years). So I take car of them and try to ensure they are built to last, I am not a pro racer so I don't need that last 2-3hp if it's going to drive cylinder temps up too high etc..

If you're concerned about longevity, Ecutek is by far the better option. Uprev has far less control over timing than Ecutek.

When you say that though wouldn't that mean the uprev would be staying closer to Oem tables which I would imagine would be on the safer side (less advance).

If you tell your tuner to stick to the oem tables, then sure. But that way you're giving up most of the gains to be had with a tune. If you leave timing alone, all you really get is an afr adjustment. That's not going to generate much power unless you've got enough mods to throw the oem ecu for a loop. But the best thing about ecutek is that it runs what you tell it to. You tell uprev what you want, and then it tries to figure out if that's what you really wanted after all.

As long as you've got a good tuner and you tell him not to go nuts, you'll be fine. These motors are stout. Guys are running 600+whp on the stock block. If it can take that, it'll be fine with a moderately aggressive NA tune. There just aren't a lot of people with popped NA motors that didn't do something really stupid.

Yea I just spoke with Seb and I feel a lot better about it now. Seems they actually relax the timing for 91 octane so it isn't knocking and pulling too much back out like Oem that is based on 93 octane. So that's comforting. They do tweak the vvel but I am not sure what they do to it. Waiting to hear from Rob e-mail and then decide if I go with specialty z off the shelf tune and then have it dyno tuned there in August or what Rob does on the ecutek tuning and maybe stay local.

Right now it sounds like Seb has a pretty nice deal since they have worked the traction control and everything in their MAP with ecutek. Looking like I can have a stock tune, a true tune with traction control tweak (so off = the tuned traction control like a GTR R mode), and also a tune with traction off=off so you can be stupid. Also buying the license and cable gives me access to trouble codes and data so it's like a scan tool as a bonus which I will use at some point I know (master tech for the last 11 years but left the industry this last year and now no scan tool access).

EcuTek RaceRom is a night and day difference compared to the stock VDC. The more aggressive throttle response is huge as well -- probably the biggest single difference I noticed. I made good power gains with Seb's tune on the stock engine:
