Diablew Tune on Denali

[DisplacedBuckeye]

Keep us updated on the process and how difficult the software is to learn and use.

Do you purchase a tune to use as a baseline or do you start from scratch?

Will do. A buddy of mine has it for Ford, and he's going to help me out.

From what I understand, you can get tunes from their site as a baseline. I'll know more when it arrives.

I'm having an in person tune done by Black Bear at their Northern New Jersey tuning event on June 1st and 2nd. Cost is $300. I don't think that can be beat, especially considering the incredibly positive reviews here and elsewhere regarding Black Bear and their in person tunes. I can't wait for the event to come up.

ETA: Black Bear holds tuning events all over the country for those of us that aren't near by. Works out great.

What differences did you notice? I'm getting an in person BB tune June 1-2 in Northern New Jersey and can't wait.

More power , better throttle response, quicker firmer shifts ( not harsh but cleaner ) , better acceleration and passing , I also had them tune out V-4 mode ( was using a range module) more top end ( had speed limiter taken out)

Very very pleased !!

I'm looking into getting a wideband which is all but a necessity from what I'm reading. I get the need for it, but how do email tunes account for not having this?

You drive the vehicle and record the Data , then send it off to be analyzed and the modify your files , then you load new tune files and record another data log so they can double check the tune , no difference really then dyno tuning, plus they will modify the tune as needed when mods are done , verses the in person 1 time tune

I get that, but we don't have factory wideband, so is the narrowband all that's used for the email tunes?

Cars have built in O2 sensors and the data logs gather this data (in addition to a lot of other data). Wideband sensors are more accurate than the built in sensors which is why they are preferable. The built in O2 sensors Have more fluctuations in readings based on temperature, etc. A wideband should be more repeatable.

I appreciate the info. So, if I've got this down, the factory sensors should be sufficient to tune a mostly stock Yukon. Wideband is mostly needed for mods that significantly change the AFM. That's probably oversimplifying it, but I'm still getting my head wrapped around the need for wideband.
