UpRev full tuning capabitliy??

pg6speed · 07-26-2010, 11:36 PM

I'm new to the need for tuning the ecu of cars as my past cars have not had ecu's in them so I called up UpRev for some info. From reading this forum I was under the impression that tuning capabilities were basically limited to A/F corrections.
I spoke with Richard at Uprev about getting my car tuned there soon and questioned him about what all they can do (correct A/F ratios and rev limiter, etc). His reply was that they are not limited to A/F and rev limit or valet modes etc, but have Full tuning capability of this ecu. Is this news to anyone or am I miss understanding something. Does Uprev have the ability to fully tune this car at their shop that they havent released to other authorized Uprev tuners??

We use UpRev for tuning our superchargers as well as N/A tuning.. not sure where you've picked up your information on UpRev, but it is a full tuning solution, and gives the tuner wide access to the ECU.

I was also under the impression that no one had cracked the VVEL as of yet.

That is correct, and some definite improvements in tuning will come if/when that day happens, but tuning the car is totally possible without, as the VVEL still functions.

Yeah, but not optimally, especially with FI...

That's a bummer... I'm surprised no one has at least figured out a piggyback method to spoof signals like the camcon does for VVTi and i-vtec

Can anyone even access the factory maps just for purposes of viewing?

Tuning is possible I understand that. When UpRev said they had FULL tuning ability I was under the impression that that included the VVEL, to me that would be FULL capability.

Does anyone know if the uprev tune deletes the governer?

It can If you want it to!

FI and VVEL can play very well together at the current levels, now if you are wanting to jump up to the 700whp range then maybe not.
The thing so far with Uprev, as they have told me, is there are no components that would take full advantage of VVEL and there is a concern that using the stock components would be useless or maybe "dangerous" for the consumer.

It is a bit of a back and forth, but I understand them being cautious with it currently.

^^Good response, on the being cautious. Thanks for the input. ^^

Here is the email I got which is a bit more specific for you guys.

Quote:

It's something we'd like to do, but the reality is that no one wants to assume the liability. It's not like a typical motor set up where if you break a valve, or a rocker arm wears you just go buy that part and rebuild.

The VVEL is only available from Nissan. Nissan will only sell the matched pair of heads as a complete unit. Approximate cost is $10k, thats just the heads, no other parts.

From what we see on the earlier motors the cam phasing alone is just about perfect from the factory. You can adjust them all day and you gain 1-2hp. With the VVEL we have no less of an expectation. So realistically no one is moving forward on the development of the software because the potential gains will be very small, and the liability is huge. Also there are exactly ZERO hardware pieces in development in the aftermarket. So no replacement pieces or items that would require a change in the tuning itself.

If these factors change we'll push forward with VVEL tuning, as with everything else in the Nissan tuning market we'll be the people that develop the technology and the other manufacturers will simply copy our work.

Thanks alot Dreamer this was a perfect answer to my concern. That explains things much better than the answers I got on the phone. I'll be going to UpRev soon to have my car tuned.

I think we should all be aware that even when the capability arrives, tuning the VVEL is going to be a challenge as I am sure few have experience doing these types of changes in addition to the A/F and timing maps. This will add yet another variable to the scheme and add to the complexity. It will be of the utmost importance to go to a really solid tuner.

No components? You mean like a different set of cams? Stiffer valve springs? You don't necessarily need any of that to take advantage of VVEL tuning -- that's ********.

Valve timing overlap and lift play a huge role in power production and effeciency by affecting the rate and volume of air ingested, the duration of time it stays in the combustion chamber, and the rate that exahust is expelled. Too much overlap, and you'll blow the mixture out too soon, too little, and you'll have too much backpressure.

It may work fine and safely with boost, but I highly doubt it is optimal because once you start changing the intake and exhaust system, the valve timing should be adjusted too.

There's no more danger from a poor VVEL tune than any other improper setting on AFR or ignition timing.

But, whatever, if they can't do it, they can't do it. Obviously it works well enough without VVEL tuning...
