Reality of a Dyno Tune>>>>> Stock ECU vs Hypertech vs UpRev
Yesterday I had the opportunity to get some dyno tuning done and see a comparison of Stock ECU, Hyper-Tech and UpRev Tune.
The car is our shop car, a 2004 6 speed G35 Sedan with the following modifications for engine performance. Motordyne 5/16 basic plenum spacer, R2C Intake, G37 OEM Y Pipe, G35 Coupe OEM mid pipe and HKS Axle Back Exhaust.
The dyno graph will speak for it self and peak WHP for the stock ECU was 210, the Hyper Tech peak WHP was 213 and the UpRev Tune peak WHP was 218. But to put things into perspective a bit more I will add my take on the matter. As you can see from the A/F ratio, the stock ECU is not able to compensate for the minor modifications done to the car and dangerously lean with A/F ratio a 15:1 at some points. The Hyper Tech unit did its best for an out of the box tune to correct the A/F back into the safe zone, but still limited. The UpRev Tune really brought this car to life, not only from a peak HP # difference, but overall picture. As you can see in the mid range area, the UpRev Tune is making 10+ WHP over the Hyper-Tech and 20+ WHP over the Stock ECU and the A/F is dead on and you can also see the difference in torque as well. The UpRev tune has yielded better partial throttle drive feel and fuel economy because steadystate drivability areas of the map were able to be tuned. Separately from driveability, the UpRev also allowed us to tune full throttle and power areas of the map, including the fuel, ignition and cam timing maps. Initial impressions from driving the car afterwards is that it feels faster, the power delivery is very linear because of the new mapping.
So in conclusion, if you are going to spend your hard earned money on Intakes, Exhausts and High Flow Cats, spend the little extra insurance on extracting all the power possible from those modifications with a dyno-tune and to buy yourself some insurance on not destroying anything in the process.
I would like to thank the guys over at Dynosty and Hal the tuner behind the results.
Dyno used was a Dyno-Dynamics which read approximately 12% lower than a dyno jet.

Lol, pretty much everyone knows the Osiris is the standard for tuning software. Thanks I suppose for the info.
For the g37 or 370 it's what everyone uses. Now on the DE platform stand-alone is the best like Haltech n then Osiris.

The info was completed to show a comparison, as I have not seen anyone Dyno the Hyper Tech and I also haven't seen any comparisons either. The Hyper Tech does exactly what they claim and not overly exaggerated claims for an out of the box tune. I would suspect an out of the box tune from UpRev would be similar to the Hyper Tech as well.

I don't know anything about the Hypertech. Is it modifiable beyond this default input? In other words: Can you tweek it further?
Thanks for your time on this.

^^^ Absolutely true, PROVIDING you have a tuner as capable as your tuner Hal. Another tuner may not have the experience and will spend time and not get the performance gain you've shown.
My point: The Hypertech works 'plug and play'. THe Uprev tune requires skilled input. Worth it if you have those skills.
Did the Uprev package come with a 'plug and play' tune? Would that equal the Hypertech tune on this?
Thanks. Good work.

I'm quite sure most UpRev Tuners have the capability to do what needs to be done.
Yes I have never disputed the HyperTech didn't work. It worked quite well for a tune in a box. The Osiris Tuner version doesn't come with any basic tune at all, you must build your own MAP. The Osiris Standard would be more along the lines of HyperTech as it is tuned based on your modifications and it can be tweaked by UpRev with their Etune option. You can data log with the Osiris standard and mail them the logs. Obviously there is a $50 fee for each tune.
