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.
