Long story short. I got UpRev Tuesday w/ a custom tune on a hub dyno.

Performance mods...

- DT LT Headers
- Berk Tech. B-Pipes
- Banks Monster Exhaust
- AEM Brute Force CAI
- 4.10 Gears w/ TT

- BDGT (until I got UpRev)

Dyno numbers after the tune...

- 415 ftlb tq
- 340 rwhp

They did a run with the BDGT before installing UpRev. TQ increased by 40, rwhp increased by 15 with UpRev.

Not bad with 35's and 7 inches of lift.

My only problem. It seems as though between 1,500 - 3,000 rpm's, I have absolutely 0 power. When it hits 3,000 it takes off. It feels like it's bogging. Lets say I'm going 40 mph at 1,500 rpm's, then I floor it, the rpm's go up to 3,000 instantly, but I don't increase in speed. When it hits 3,000 rpm's it takes a second to shift but the rpm's don't drop, it shifts and you sh!t your pants.

I don't seem to have this problem if I'm stopped, only when I'm already rolling and I floor it. I do have the wot restriction off.

I think it may be the a/f ratio. Idle is 12.6 - 12.8. It stays in that same range if I drive like a "normal person". The max it hits is around 18, the lowest is around 10. From what I can feel/hear, it sounds like it's not getting enough fuel fast enough. I don't know anything about a/f though.

I never noticed this with the BDGT. When I hit the gas it took off, no matter what the rpm's were.

Any ideas?

If your idle A/F is like that then that means the ECU MIGHT be stuck in open loop. Typically in closed loop it would aim for stoich but you're damn near rich which in my opinion means it's running in safe mode. I don't know how to fix that problem since I have no experience with UPREV but I would definitely contact them ASAP. I think they would have more information regarding your problem. But I've had a similar problem in a LS2 GTO and what ended up happening was the ECU wasn't flashed correctly and ended up going into safety mode. As soon as we tried flashing another tune on it to correct the problems it went into lock down. Messy process because it then had to be towed to the dealer.

dohh... subscribing as i'm curious to know what the problem is. looking to get UpRev soon myself.

What'd Tim say when you asked him about it?

What'd Tim say when you asked him about it?

Well after I had left yesterday I knew immediately that the wot restriction was still on. I figured he must have forgot to turn it off. They were closing as I pulled out so I waited until they opened today to call.

I told him that it's definitely restricted. He said he has never heard of a truck with a wot restriction. So I explained it to him and he said to stop by and he'll look at it. I stopped by late today. He called UpRev and they told him basically what I said, the 08's + don't have it, blah blah.. He fixed it no problem. We took a test drive to make sure it was off. It was. I figured my problem was fixed.

As I headed home I noticed what I described in my first post. I thought it was just part of the wot restriction, but apparently not.

I will give him a call tomorrow. I might call UpRev first to see what they say.

 

[TiTAN-]

I had no time to call today, hopefully tomorrow.

The BDGT definitely gave me better results all around. Which leads me to believe something Isn't right with the UpRev.

If he can't fix it, or says that's just the way it is... I'll be demanding for a full refund. After spending $600 I was expecting everything to be damn near perfect.

I'm not hating on UpRev yet, I'll wait and see what happens. But as of this moment I wish I would've just kept my BDGT.

It feels like all they did was return it back to stock with the BDGT, and never installed UpRev. I was able to spin my tires with ease before on accident. Now I can't spin my tires if you paid me. The shifting points are all out of whack as well.

/rant.

Yeah something doesn't sound right. The first time I got my uprev tune at Injected Performance in Kentucky I was disappointed at first because I thought I lost power over my Superchips Cortex 93 tune but I soon realized the SC changed the throttle response to make it SUPER touchy which gave it the illusion it made more power under normal driving but once I stepped on it the Uprev felt faster. I was just use to not having to push down on the pedal as far to make it haul azz so it got some getting use to.

Luckyyyyyyy.





Nope, nothin helpful for you. I'm just a 20 year old who has no performance mods on his truck. haha.:bangit:

i'll put all those performance mods on my truck and trade you trucks. how's that?

 

[honda250xtitan]

^^^^^^^^haha...let me think about it for a couple years.

whaaa? lol... but you haven't seen the laundry list of mods done to mine. :eyebrow:

 

[w00t692]

Um... just a question. Is uprev just a simple reflash or do they dyno tune it to your mods. If it's the former, i guess i'd blame it. If it's the latter... i'd blame the tuner not uprev.

 

[gweasel77]

First of all, congrat's on getting Up/Rev Tuned!

Idle is 12.6 - 12.8

Shouldn't the AFR be in the 14's @ idle?

The max it hits is around 18, the lowest is around 10

That's not good! Is this with Cipher?

I wouldn't blame the software yet...

 

[w00t692]

Ok, i'll lay a few things out for you about how engines handle afr's and what the numbers mean.

first and foremost, your idle should DEFINITELY be 14.7. Granted it won't be 100%, so 14.4-15.0 is 100% ok.

second, going to 18:1 at part throttle sounds like you have a lean spot in your fuel map, but if this is just a general number that you see in the datalog, then you need to observe what the truck was doing when it happened, that lean usually = let off the throttle.

and 10:1 is actually kinda normal if you floored it, but definitely not normal if you're at part throttle.

all in all: part throttle 14.4-15.0, Wide open throttle: 12.6-13.0

If you actually posted or provided me with the data you're looking at, either with screenshots of the areas where it's ****ing up or something like that, i can tell you what's going on.

A dyno tune and street tune a two totally different animals. A dyno tune is that, it gets the highest numbers for bragging rights, most do not work the best on the street/track. Why, The dyno tries to simulate the rolling resistance and aero drag in the vehicle. When this tune is run on the street the real rolling resistance and aero drag comes in to play and the tune needs to be adjusted with datalogging and E-Tunes to optimize the A/F and fuel maps to your Titan.

The members that i have run with at the track and have been dyno tuned do not use the dyno tune, they use there street/track tune to get the best ET out of there Titan.

Datalog you titan, then post them on here, to see what is really going on. If your at 12.8 at idle your really rich, should be in the 14-15 range, if the A/F is fluctuating between 18 and 10 at WOT there is some thing terribly wrong. 18 and 10 is the max and min. on the A/F range.

 

[w00t692]

Oh and i must mention. If you are at WOT and hitting 18, depending where in the RPM range it's hitting that, that is absolutely 100% the reason it would feel flat and torqueless. lean = no torque. rich = bogging down, engine is quieter, but lack of power production

He didn't mention being at WOT for the 18-10, just that the max it went was 18 and the lowest was 10.

Funny thing is, that's completely normal if he sees that throughout the entire datalog.

let off throttle, injector shutoff = 18:1
floor it, instant throttle response = injectors dump fuel responding to throttle input, but air hasn't reached cylinder yet = 10:1

from my understanding ANYTIME uprev is done on our trucks it automatically removes the wot restriction, so i know that definately isnt the problem. it almost sounds like the effed something up on the tune....have you tried another map? see if it does the same thing on like the 87 octane tune or economy tune....i know my economy tune my truck runs like garbage..

When you fill out the order form when you order Up/Rev it asks you for each map whether you want WOT enabled or not.

IMO i believe its the tune. The tune might be off causing the truck to go into "safe mode". Resulting in power loss.

My idle is 12.5 to be exact. I'm not sure which one I have? I was told he does custom UpRev tuning on the dyno. He said it would be $600 for 5 maps. I never got to mention what maps I wanted though. After he finished he said I could come back and he'll re-do them to whatever I'd like.

Check the attachment. That is at idle. (The BDGT is only plugged in for numbers/temps. It doesn't have a tune on it obviously.)

Full throttle, then letting off the gas = 18.6

Normal throttle = 12.5 (consistent, +/- 2)

WOT throttle is just above idle, around 13.0

I have absolutely nothing from him but a receipt. I can't datalog anything.

This is exactly what I'm experiencing. Both lean and rich, if that's possible?

The only other maps I have are some stupid sh!t. Valet, anti-theft... I forgot the others.

Agreed.

I think it's the installer personally. He knows his stuff, just not on trucks. 95% of the time they tune cars. When I told him my WOT restriction was on, he demanded that it was off. He said, he doesn't know of 1 truck that even has a WOT restriction. So I drove down there, sure enough I had to prove him wrong. He called UpRev and they told him what I told him.

Also, get this... There was a Raptor next door. I asked him if he's put any Raptors on the dyno. He said, "yeah the off-road golf cart type things". I said, no the F150 Raptor. He said, "oh like the rhino's and the ranger's". I gave up and said nevermind.

I'm dialing his number as I finish typing this. I'll update you...
