Dyno day

brutusvk

I got my Uprev tuning done at Xact Dyno in Tempe. Tim is a good guy to work with. Very nice and super patient with all of my questions. All said and done I ended up just about 315 hp to the wheels. My baseline with the intake and exhaust was 295. So I picked up almost 20 more hp from the tune. The numbers don't really give the whole story. The car feel much faster. I am pretty happy. It is my daily driver after all. I have a "race car" in the garage. But I do not know much about these modern cars and ECU tuning. So, I hope the numbers are good.

Here is a link to a video...

so you just have an exhaust and intake? ... also pretty sure they'll move this to the tuning section

Just an intake and exhaust for power upgrades. (All Stillen) I have an oil cooler but that doesn't exactly build power.

That baseline run seems high for a CBE and Gen3 intake but a dyno is just a tuning tools. Picking up 20 from the tune is pretty decent. Not to mention the secondary stuff you pick up (full throttle 1&2 and all the way to redline)

Nice gains

Can you explain this? I've never heard the stock tune being limited in this way before, but I've only owned my Z a few weeks

The tuner said mine and the 2014 he tuned the other day were super close in numbers. He did three baseline runs. All were between 292 and 295. It was still really rich before the tune though. From the responses I guess she is making good power. It is all new to me. Maybe it is because it is such a new engine. I just hit 1500 miles the day we tuned it.

Use a Mustang Dyno for true whp numbers. Most other dyno brands are way optimistic. My stock 370z achieved ~260whp on the Mustang dyno, which is in line with typical drivetrain loss (21%).

I'm only educated on the 6MT tranny. I would assume its similar for AT. you only get partial throttle in 1&2. full throttle doesn't happen until 3rd. also the ECU starts to shut fuel off I believe around 6800rpms until full closed at redline. UpRev will give you full fuel until you hit the wall at redline.

I put down 262 stock on a mustang and 314 with gen3, cbe and hfcs

wonder what i'll get with intake, exhaust, plenum mod and test pipes... but i'll have to wait till i can manage to stop spending money on dumb things lol

Jordo!

The only way to get a "true" measure would be to unbolt the engine from the chassis and dyno it that way.

Mustang dynos are no more accurate (in this context, meaning able to yield consistent, repeatable measures) than any other dynomometer. However, like all load bearing dynos, they can be set up quite differently from shop to shop.

Your car will likely put down very different numbers across Mustang units, depending on the various starting values inputted by the shop.

Dynojets are the only dynos I am aware of that are highly consistent across units and shops, given that all calculations are ultimately based on the rate at which the drive wheels can accelerate the known (and fixed) weight and diameter of a rotating drum.

For all dynos, there are also transient factors (e.g., various ECU trim commands) that are difficult to perfectly control for, and also correction factors that compensate (imperfectly) for ambient conditions. These too will result in some measurement variance across runs for the same vehicle, even on the same dyno.

Dynojets are somewhat less desirable for tuning under partial load, but that is another matter...

The OEM tune tends to restrict full throttle opening, especially under low load. Because it is "fly-by-wire", this can be adjusted in a table that commands throttle opening in the ECU, which with some tweaking, can result in snappier throttle response. There's also a "soft" rev cut that pulls fueling as you approach redline, as another poster mentioned, that can be changed.

There are other factors that can be adjusted as well (e.g., torque restriction on gear shifts in the auto) in the ECU maps to affect how the car responds to various driver inputs.

I'm not an expert but tuning during the summer in Phoenix and I'm guess temps were over or close to 100*, pretty sure there is still more room on the top end. Solid numbers regardless.
