I just got this in an email from the head of the tuning department.

Darnell,
We just ran these this morning, back to back. The comparison was done on a 2006 Nissan Titan with 5.6L V8. The runs were about 10 minutes apart, and there were no differences in ambient conditions between them.

Conditions for Hypertech to UpRev respectively…
Ambient air temp was 89.5F to 90.75F
Baro Pressure was 29.911% to 29.919%
Humidity was 55.25% to 53.60%
With an overall STP Correction factor of 1.056% to 1.057%.

The conditions are almost identical, and as repeatable as can be made. As you see, the Hypertech tuning makes more power down low (as torque ramps up) and more power at the topend. Our tune makes 3-4Ft-Lbs more from 4500-5200RPM, and 4-5HP more above 5600RPM. The lowend torque is difficult to measure below 3500RPM due to the torque converter slippage, but the separation above UpRev’s tune between 3000-3500 indicates that the engine is making more power with our tuning. Although the spread in the curves at 3300RPM shows us making ~10Ft-Lbs more, that is probably a quick jump in power due to the RPMs ramping up just before the torque converter begins to hydraulically lock-up. The separation is real, but the brief separation is not indicative of the true power of the engine, rather of the power through the entire drivetrain with a lot of dynamics due to converter lockup.

Discuss.

Very impressive, but which Uprev tune was used, 87,89,93?

Who's truck was Uprev tuned? What were the components? This is seriously lacking data/info for me to take you serious. Anyone can type up some words and draw on a graph. Sorry.....I'll be your first naysayer here.
Roy365,

The same stock 06 Titan was used for testing the premium fuel tunes from both Hypertech and UpRev. As far as lacking data/info I'm not sure what else you need, but let me know and I'll see if I can get for you.

If I am not mistaken.....your unit doesnt fully override the WOT/torque management system correct? Either something is wrong here or you arent showing where the WOT is showing it's ugly head. Hell who knows you guys may be onto something, but seems like the competition would be all over it as well. (torque converter) No one has cracked the TCU yet that I know of, or have you?

Roy365,

You're correct currently we don't fully remove the WOT restriction. But there is no WOT restriction during a single gear run. It's the same as if you were driving down the road at 30MPH and punched it there wouldn’t be any WOT restriction. The WOT restriction is only there at lower speeds. We have tested this many times.

And Roy Naysayer or not I'm glad you're asking these questions.

I understand your point on the single gear run........of course it's going to be close. It's pretty dang easy to go in and set your AFR's on a bone Titan and have these type results. You line your test vehicle up and let someone else line their Titan up with the WOT removed and see who's in the lead. Your graph doesnt even show where the VK56 makes the torque. Why did you start at 3K rpm;s on your dyno chart? You purposely leaving off where the Titan and Uprev shine? Your single gear pull isnt realtive in real world applications. I'm not knocking your product......just your approach sir. :cheers:

I don't see anything wrong with here. This isn't a 0-60 pull or a drag race. I haven't done the math but WOT may not be applicable here since in third gear and doing over 3000 RPM it seems you would be going at a speed that you would have full WOT anyways. Even more so if this was a 4x4. Looks like great gains for a new product. There is no TCU trickery here that I can see.

Well if this was an apples to apples comparison, both running the 93 tune, you have a winning Hypertech product for a stock Titan. Darnell, it would be great to see a Hypertech, Uprev and Bully Dog overlay.

im with roy 365. this is just showing us that it can make the same power when the truck is rolling. but from a dig the UpRev will take the win.

Not trickery.....just kinda reminds me of the daily news and how it is portrayed to the public. Yes on a 4x4 it wouldnt matter as much, I'm going on my platform in that sense and I drive a 4x2. Also I am aware that on the Titan a dyno pull is a bit different for my truck because gears 1 & 2 are deemed pretty much useless because of the way it shifts. You cant hold the Titan in a gear and do a pull like normal, or at least on my model.

The numbers ARE impressive.....obviously I wouldnt even pull the :gunz: out unless it was making good gains and was in the ballpark. They do have a point.....but so do I and a few other owners. Some of us NEED the WOT removed.

There is a lot more to tuning than just adjusting AFR even on a stock truck. And I wouldn’t be surprised if the truck with WOT removed completely wasn't behind due to a loss of traction.

As for why the numbers start at 3k it’s because any numbers below that are not going to be repeatable due to the converter being unlocked. Also a single gear run is the correct way to dyno and vehicle and since our dynos take into account the Titans weight and aerodynamics the numbers are very relative to real world applications.

Seems legit. Hey can we see a hypertech vs bd test? I'm currently in the market and looking between the two. thanks

Looked pretty easy to me when I was shown how the software worked. If i were a gambling man....i would put my money on a good driver and WOT removed vs. it remaining. When we tuned my truck........we got the timing and AFR's right with a few pulls on the street.We produced an Uprev comparable tune in regards to timing and AFR's pretty simple and relatively quick. But, the huge difference was the WOT restriction was seriously hiding the power and hurting my 0-60 times. And until we tweaked the voltage to get around 4volts on the throttle it wasnt even comparable. I cant speak on the traction issue......I have 22's, traction bars and Tru-trac, no worries there. My interest isnt just to get more HP....it was to have usable HP at all times for 1/4 mile runs and 0-60 rips.

I believe UpRev can match the tune of any programmer if all that is being changed is AFR and Timing.

Congratulations on the Hypertech tune for that particular truck and take the UpRev tuner for that vehicle out back and shoot them, I hope it wasn't Randy because he's tuning my truck, lol.

What it comes down to for me is that I'm sure the generic tuners will do a fine job but at the end of the day it will still be someone else's tune going on the different trucks and the chart displayed may be a fine example of why not to do that.

Maybe that UpRev tune worked great on another truck but it is obviously inadequate adjustment for the truck you tested and if UpRev sent you someone else's tune, that would explain the large difference in power.

What would happen if you logged the data from that truck and sent it to UpRev? Do you believe they could then match the power advantage the Hypertech has on that particular vehicle? What's the AFR and timing on the Hypertech truck? You don't have to worry about giving up any secrets, the cat will be out of the bag as soon as someone logs it with UpRev anyway.

I was at the track with a guy last week running 37 degrees of timing and a low 11 AFR and his truck was flying but I would not run those values on my truck.

At the end of the day, I want to log my truck and have a custom tune because in my mind, the more power a tuner puts out, the more I want the timing and AFR values monitored.

This is not surprising to me, because it was a stock Titan. What would really tell the story would be time slips from the track.

I say take that same truck to the track and see how similar the results are between you and uprev.

I apologize, I looked at the chart and realized there was not as much difference in the power as I originally thought so the UpRev tuner should not be shot, especially if it's Randy, lol.

I am still curious and my original questions still stand because to me, the tuners should be near equal and the only difference will be the ability to monitor and later on, DIY custom tune.
