ecu-tek / UpRev
 

can someone explain.. is this two different tunes?

if so which one is best?

There are probably 50 threads discussing this. They're two different software programs. Ecutek has more features and works better, but it's more expensive and there are fewer tuners.

Thanks .. I have learned you get what you pay for!

Thanks - you always have good feed back!

Your estimate of the number of Ecutek-vs-Uprev threads may be a little low. ;)

Good Lord. :rofl2:

So basically, I see it this way, if your car is NA, with bolt on's and no desire for flex fuel, then I would go Uprev. But if you plan to go forced induction, and would to add extra sensors etc, I would go ECUTek. Keep in mind, if you have a base model, ECUTek does not have FFS, and LC.

Uprev does offer this to both. I just became a tuner for ECUTek over the weekend. I haven't dived into it just yet, but it looks very promising. Also keep in mind that ECUTek does NOT offer live tuning.

Regardless the car is NA or FI, Ecutek is a better program. It gives the tuner far more control over timing.

In regards of what? ECUTek reads in BTDC, which is helpful, and UPREV uses burn time. In the end, it does the same thing. And technically, ECUTek only reads BDTC in the custom maps, and not the actually reversed engineered tables. It reads in burn time as well.

While I won't say it gives "far more" control over timing, it's is much easier to do the timing tables in ECUTek.

But, in the end, it's on who is using the tools to make the effective. I'm still learning both of them.

There's a post somewhere in here from a few years back from Visconti that explained it far better than I'll be able to do. I'll track it down if I can.

Short version is our ECU's have very complex timing maps that are constant changing things based on many different variables, some of which really don't matter for a performance only tune. Uprev does NOT have the ability to guarantee the timing settings you put in actually are used as entered.

ECUtek simplifies the timing maps so that all these "other" variables can't affect timing and you actually get what you enter instead of the ecu doing whatever it wants.

If the ECUtek was around when I had my car tuned I would have used it instead of Uprev.

the term "better" is subjective to the end user and the person doing the tuning. if timing control is the main reason you say it's better they both do just as good of a job with ignition advance. How good of a job a tuner does with the software is entirely up to the person behind the computer.

They currently both offer Launch Control & Flat Foot Shifting. only thing that currently puts ECUTek over UpRev feature wise is the flex fuel and boost control. I wouldn't say "ignition control" makes it better, specially if you are N/A.

^^^ finally someone that is honest.
I find controlling timing with UpRev and ECUTek to be just as easy to use and just as reliable for the N/A Crowd.
if you are boosted then ECUTek makes sense, ONLY if you go to the right tuner that uses the custom tables to maximize efficiency for the customer. (I'm not talking about just the timing table but the other custom tables that Pro-Tuners can make) while I've seen cars roll in here with ECUTek and Zero safety features. some lean as far as 13.8:1 AFR at wot with boost & zero safety features made to prevent the customer from melting the engine. others that have very good safety built in that allowed our tech to fix the issue before customer had a nuclear meltdown. Not being able to tune the car in real time is a huge bummer for ECUTEK, that feature would save us a ton of time.

did not mean to start anything, i thought with a tune after my mods i would just be improving performance to further enjoy the modifications, such as possible better response, sport mode,then better gas millage on highway motor after map and not restrict motor?

**Does stock computer need tuning after exhaust and HFC installation?

Wish i was aa smart

Whatever you decide, find a reputable tuner. In fact, I would spend more time on tuner search preferably one who has worked on the VQ.

Actually, it doesn't matter if you have the base Z or Sport or Nismo, EcuTek includes LC, FFS and TC for all of them.

The reason I chose EcuTek is because I plan on running E85 eventually, and according to what I've read in the past, the tables for timing, VVEL and fuel are higher resolution.

Oh really? When I talked to the guys at ECUTek at SEMA they told me they didn't have it for the base.

I haven't had a chance to try it since mine is a Nismo.

It's what Seb at SpecialtyZ told me.

When you think about it, the only real difference between the base and the Sport/Nismo is the rev syncro. I don't think that particular feature has any bearing on TC or FFS. Since I'm still running the "off the shelf" tune, all I have at the moment is LC when I have VDC turned off. Seb says that once we get to tweaking maps 2 and 3, map 3 will have TC.

As for FFS, I'm not too concerned about it if I have that one or not. I used to FFS years ago in my old '96 200SX SE-R, '91 Ford Ranger XLT and '83 RX7, and I didn't need to have any software to help me with it. Back then, we called it speed shifting or power shifting.

The main difference between the two as far as the general idea of engine management is that the Uprev uses MAF sensors which is a very simple, non enough complex in my opinion way of fuel/load management. The Ecutek uses MAP sensor (Speed Density) which is better/more safe, especially in case of FI cars.

One thing definitely against Uprev is the support - they do not answer emails, I'm waiting over a week and no reply. I was about to purchase the ARC feature but no response from them.

Also I've heard the Uprev plan to add the Flex Fuel feature in the future.

They were all at SEMA last week, try emailing again. They are working on flex fuel support

I can confirm they were at SEMA as well. I don't think they had a booth, but were there to attend.

ECUTek does offer hybrid where it can use MAF, and SD depending on the parameters you setup.

I think the only reason why someone would want to do this, is because MAF does idle much better with cars and aggressive cams. But I can't think of any other reason to that.

If you look, in the software you can see where it says "Synchrorev only"

I have a base model with ecutek can confirm that the ffs and lc are active on my car. In the software it says that it's not supported but my tuner tried them both and was suprised that they worked.

Also I passed inspection in Massachusetts with the tune.

This information wasn't out there when I chose ecutek vs uprev, but I'm super happy with the tune and can recommend Kaizen tuning.

I may be wrong but the base model comes with an open diff and that may be why ecutec doesn't want the lc and ffs active, I have a quaife installed on my car.
