Diablew Tune on Denali

[livingez_123]

Thanks for the input. Did the tuner ride with you to do the tune, or did you do the datalog?

Dyno.

I don't know the tuner you're referencing but...... The Diablo intune will run you $370 on a good day... The Diablo trinity will run you $600 on a good day...

That means you're probably getting the intune and your "tune" is costing you $100... Think about it a minute.... $100 for a CUSTOM tune.... 95% of my shoes cost more than $100... Do you really think you're going to get a true custom tune for $100???

If you truly are, you Sir, have found the unicorn the world has been searching for and I congratulate you...

My thought is, you've found a shop who will take a custom tune they have on file, look at your emailed data and adjust the timing on their "saved" tune to prevent detonation.... Then email it to you..

Will it work?? hell yeah. Just about any tune is probably better than the factory tune... Is it custom for your driving style, mods, type of fuel, etc? I doubt it... But hey, like I said, maybe you found the unicorn......

And again- I loved the Diablo. But I also had a $300+ tune on it that took numerous versions to get what I wanted... Maybe I was/am super **** about how it drove... However, it was a Hemi and I wanted it to act like one.....

Lew is his name, and he's pretty big for the trucks. I get what you're saying, but the same thing could be applied to the BB tunes. Unless there's somewhere I'm not looking, all of the Autocals I've found are north of $600. I don't think BB is paying me to do my tune. That's my primary question I guess. What does BB do, that Diablew doesn't, if anything?

It sounds like you think it would be best to go with the guy that's local to me. It would be a street tune as there isn't an AWD dyno around me.

I have had both tuners, Diablo and Black Bear but never a Diablew tune. The Black Bear was on my old 2001 Yukon but for the 2011 Denali I picked up a used Diablo Intune for $200. I liked my custom datalog BB tune and the option to activate the E-fans. For the Denali I wanted the option to adjust parameters easier than shipping the ECM to BB and back. I think for a stock pre-loaded tune they are comparable but for the datalog versions can be determined by dynos. I think either tune will work great and I know there are more people running HP and EFI than Diablo CMR/Trinity.

I was looking at these too. Planned on going with black bear but curious why the diablew tune states they don't tune anything with a supercharger, medium to large cam, or turbos through email. Is that pretty standard for tuners? Too difficult to do through email or just diablew?

Its besto to have a local dyno tune if you have all those major type modifications

Personally, I've always preferred an in person tune.... However, I was running a modified car... If you're just looking for a small adjustment, I don't see where an email tune would hurt....

Again, it's a Yukon. Not an SS Camaro. So I'm sure an emailed tune works great... I've just never seen a ton of good coming out of an inexperienced person plugging a tuner in and making adjustments.....

So... I've always went the route of having an experienced person making experienced changes. I'm sure you'll be fine either way... It isn't like you have a cam, SC or turbo with aftermarket heads...

So just flip the coin and enjoy the ride!!!

I figured that. I don't have those mods but just curious if it had anything to do with the tuner or software. Being from a very rural south Arkansas town, getting a local dyno tune is not even available. At least not within 200 miles to my knowledge.

EFILive allows for more customized tuning as far as major mods.

I ended up going in a completely different direction and grabbing HP Tuners. I'll load it with a tune and slowly tweak it myself.

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.

I installed my AutoCal BB Tune yesterday and man what an improvement, I'm very pleased , no regrets at all !!

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

 

[Bowtiebug]

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?

 

[Bowtiebug]

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

 

[DisplacedBuckeye]

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.
