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

(red)
Ecutek, 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.

My mechanics g37 with bolt on's and e85. Granted it's on a dynapack, but still great numbers.

If it's not a dynojet just throw the numbers out the window and focus on the before and after number gains. I find these numbers hard to believe with just a tune difference and a few months. Those numbers do however look like a gearing change. There's just no way 19.69 peak HP between tuning software unless the uprev was a sh*t tune which I doubt if it was the same tuner.

All are uprev from a customer of mine.

The blue is tuned 4th.
Red is tuned but with my ported upper, lower and TB's added in 4th.
Green is same as red but 5th.

I agree. These numbers are much higher than others with similar mods. I was hoping for somewhere in the 320's, so this blew me away. I plan to call PTuning and ask for the initial dyno results so that I can compare the numbers before the Ecutek tune. I'd also like to know what gear he used. Although I would like to put it on a Dynojet, I just don't have the funds for that right now. This tune and a brake job were the last two things in my budget for the next six to eight months. Yesterday while doing my brakes I noticed an insane amount of ozone cracking between the treads on one of my rear tires. I'm sure this is the result of being a garage queen with very low miles on eight year old factory tires. So now I have to drop several hundred bucks on tires so I can safely run the car on Road Atlanta at the Z Nationals next months, so there's just no cash right now for another dyno run.

I completely agree. I ran a dyno jet this summer, went from completely stock to what I am at now. stock run on a dyno jet I was 268 WHP. after 4 months of working on the Z and 10K of parts installed with an UpRev tune I'm only 317 at the wheels without nitrous. 344 is impossible N/A I can't see those numbers being legit

268hp seems really low for stock. I thought the average was somewhere in the low 280's?

Although I'm not arguing that my numbers are off, I don't think 344 is impossible on a NA motor. The exhaust cams combined with other bolt-ons may very well produce those numbers, but their installation requires a great deal of work.

Hey man, not knocking on you at all. I believe he saw those numbers, I just don't believe that dyno is calibrated right.

268 is a pretty normal stock pull on our cars. I'm up in Canada and at the time of a base run I believe the humidity was 46% our cars are usually between 265 - 285 stock on a dyno jet. so a run of 268 especially at the humidity and elevation I'm at seems right on the money.

My Z is running all the engine mods I believe you can get besides going forced induction. its also been tuned by UpRev themselves also custom building me a MAP right form there own office. Im running the Motordyne 400 HP package as well with a full header, exhaust, & intake manifold replacement and I still can't break 317 hp.

If he has some upgrades on his car that are actually pushing it to 344 on a properly calibrated dyno, then I will rip my engine apart and put his same mods on because those numbers are impressive if there legit!

Have you considered the exhaust cams? I've read a little bit about them. Their claim is an additional 30whp gain.

I actually did consider a cam but the gains were not worth the cost to me. The biggest gain I saw was a 30+ torque and a max of 10 hp increase and that was with no dyno charts to back it up.

The cost after labour was almost $2500 - $3000 CAD... i also looked into a lot of the reviews and I was coming across a lot of people putting the stock back in after a while because of constant issues.

I had mentioned the cam to UpRev before the tune but had been told by UpRev themselves that they have seen serious issues with tuning when changing the cam out, so I would likely loose the UpRev power gains due to the thresholds changing to accommodate the new cam.

Plenty of info in here...320's, 330's..

Here is the response I got from the email I sent to the tuner:

"Rob, I did not do a baseline on your factory tune, since most cars come in with the AFR’s far off from where they need to be. Your dyno pulls for the tuning process were all performed in 5th*gear. Dyno Dynamics does normally read lower for most, but not every car, in comparison with a dynojet."
