Nismo ecu swap?

There was a thread on here a few years ago that discussed the difference. iirc the only difference was slightly better timing advance.

Ok so that's what I figured was it would most likely be a more advanced timing.

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.

True, but they also have to tune thousands of cars on a single tune and want to minimize problems. Different altitudes and available gas octane ratings across the country are examples of variables that have to be accounted for in one tune. For these reasons, the OEM tune is extremely conservative.

A competent tuner can make your car come alive and still keep the car plenty reliable. Seb at Specialty Z is definitely one of the more experienced tuners out there.
