Uprev vs Ecutek
 

I claimed my free Ecutek kit this year. Here is my Uprev vs Ecutek tune. I dyno-ed last year w/ uprev after installing the Z1 ported upper and got a retune to see if the ported mani did anything... it did not, it seemed like I lost power. My numbers from last year w/ Uprev are the same as the base run this year (blue). Thanks to Tobin and Godmodz for the sponsorship and competition. I can definitely feel the difference w/ Ecutek and the racerom features are really fun to drive w/.

Mods:
(blue)
Uprev, FI CBE, ART pipes, Stillen g3, Z1 upper

Nice gains throughout the powerband. Rob seems to know his stuff when it comes to ecutek.

I realize the gains here are pretty significant and that's the important thing, but I'm curious to know why are the overall numbers are so low? On average, it seems as if a brand new stock Z makes around 285 rwhp. Why is your best run showing just that with all of these modifications?

He made almost 318 with ecutek.

This dyno obviously reads lower than others that have been posted on the forum. all dynos will read different, there are just to many variables to factor in. i made 316whp on this dyno with the same tuner and similar mods.

Interesting. Thanks for the reply.

I'm scheduled to have Ecutek installed tomorrow by a master tuner. I'm looking forward to the results.

Cool, nice results. I'm curious though is this same tuner vs same tuner at relatively same timeline? Just wondering how much of a controlled experiment this was. I myself am on ecutek and happy but at the time uprev didn't have the ignition table they do now etc etc. just odd to have such gains difference when both supposedly can adjust the fuel and ignition tables the same now. Ecutek still seems to win on features and the adjustable traction control is what did it for me but don't want to make them seem a bigger difference than they are (don't want to bash uprev unnecessarily, competition is good for us end users). I would think the software can only do so much for power gains and then the rest would be what additional features are provided.

Ok, I'm an idiot. I wasn't looking at the bar graph, just at the red and blue numbers listed on the graph: 287.393 (red), 258.652 (blue), etc. Now that I realize my mistake, 318 makes perfect sense.

Thanks for pointing this out.

It threw me off too. Post up your results after your tune today.

These results are better then I could have hoped for. This seems pretty high, but the car feels pretty damn fast.

The tune pretty much cleaned up all of the throttle lag, the idle is much smoother and it feels smoother all the way through the powerband. It feels much more responsive and it is seriously noticable in the higher Rpms. I didn't get to play with it much today. Rush hour traffic prevented that from happening. I will definitely play with it more this weekend. https://uploads.tapatalk-cdn.com/201...1926e04399.jpghttps://uploads.tapatalk-cdn.com/201...49048826f5.jpg

Wow, those are great numbers. That's what most guy's are hoping to see and end up seeing about 20hp less. Nice job!

I've read a lot about dyno dynamics being a real heart breaker because they are usually 1-2% lower then a Dynojet. It sure didn't break my heart!

Have you had a chance to do much testing with the butt dyno, how's it feel? :driving:

I did a brake job today and then took it out for an hour test drive after. It feels awesome. Extremely smooth and responsive throughout the entire power band. It's almost scary fast now. I'm thoroughly impressed. The traction control doesn't kick on as easily, allowing me to have more control and freedom and the slightly higher rev-limiter is a nice touch.

Because I don't have the syncro-revmatch trans, the only other map I have is for valet. We spoke about an economy map, pops and bangs and a ghost cam, but I decided against all of them. A lean economy map could possibly damage my HF cats. Pops and bangs and a ghost cam sounded unnecessilary streneous on the engine for no real gain, other then to sound cool.

Far and away the highest numbers ever posted for a stock VQ37 with bolt ons and a tune. Put it on a different dyno, those numbers are whack.
