UpRev for Dummies?

Does that sound about right? Throttle position is 4.11, and if I rem reading it here in the thread that's measured in volts indicating WOT at 4 volts plus?

That sounds about right

Thanks. That's running on the base ROM, so I'm figuring after the tweaking by Uprev on the next tune I should be pretty dialed in. But then, I've added resonated exhaust tips (prob no change from that) and will have swapped out the catless PRTs with catted ones. So, new data logs planned before sending them in for tweaking. Finally, one thing that's become more noticeable is the loss at the low end, but that seems normal, again, from what I've read here.

Last night I was screwing around in the snow an hit the rev limiter between the 1-2 shift an sure enough, went into limp mode.
Should I be ditching uprev for now

The base ROM is not tuned to "a truck" or your truck yet. If you have free etunes use them to get dialed in. Usually the best way to etune is to have all supporting mods done and on the vehicle for 300miles or more.

I wouldnt...but I'd get a etune update and note the problem.

+1 there's a fix for it now, I just spoke with Hans recently

When using a 93 tune, is it necessary to use 93 0ctane fuel?

That was a good one!

My question falls along the same lines. Do you have to ask them to remove the WOT restriction and do a timing advance, or are either of those standard elements of the tunes?

Yea it pulls it from the Lamda sensor. The MAF is part of the fueling calculations though.

Lamda Lamda Lamda!

YES!

It is VERY important that you don't run any fuel with less octane than what your Map is setup for!!!

This could cause detonation, which is NOT good!

For example: My 91oct & 93oct Maps are pretty much identical, but my 93 oct Map has higher ign timing values to get the most performance possible out of my Tune!

Is there really that big of a boost from 87 to 93? Or do you use the high octane primarily at the track? Gas is expensive enough and I've got a lead foot.

I think so,,, I got my first tune on all maps 87 tune ,,,After first e-tune I could feel diff,after second and third tune ( me telling them to f the 87 and a all out tune) it was a Whole lot more buttdyno results!

I have an 06 4x4 Big Tow with an AFE stage 2, true dual setup into Magnaflow magnapacks with dual side exit in front of the axle. In the garage I have a box with OBX headers , JWT S2 cams with a set of catted PRT b-pipes on the way. I pretty much know I need to get UPREV. My question is how to best go about it. There's a tuner locally I have'nt been in contact with yet but I'm wondering if I should buy from UPREV and use the provided tunes or buy from the tuner and have it all done there or risk having a brain cramp logging and emailing. I've got a chunk of change sitting in the box and I want to do it in the simplest way possible. Not trying to be the fastest but I want at a minimum a 13sec truck. What's the route I need to be headed in?

[seymore4]

If you're doing cams I would highly recommend getting a dyno tune, it would be beneficial for you to have the cable as well tho so you can monitor engine parameters, check and clear codes, etc. So basically buy a used Osiris standard with no etunes and go to the local guy for tuning
