Uprev vs Ecutek

[mag_black]

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.

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.

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.

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.

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."
