ecu-tek / UpRev

Diabel

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.

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.

Wish i was aa smart

axmea?

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.

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.
