Inexpensive tune?

[pacem]

I hear about Blackbear but it is expensive. Is there an inexpensive tune I can get?

2008 tahoe LT 5.3L

I want to turn off that fuel management 4-cyl stuff and maybe optimize shift points

Not much cheaper but if you can find a used Diablo sport tuner it will do what you want to do. Just make sure it isn't married to another vehicle.

IMO, you get what you pay for. Replacing a $3,000 to $4,000 motor or transmission because you want to save $100 to tune it is completely not worth it...

I don't think he is saying that, simply...you get what you pay for. Nothing wrong with handhelds but the more expensive bb is more custom tailored to your truck.... like going to buy a suit from sears or going to a custom tailor... yeah the suit from sears fits but the custom tailored one fits better....and it costs more...

Nope. I'm just saying you get what you pay for. You can spend $200 on a hand held tuner, that will give you a generic tune and turn off AFM. Or, you spend spend a little bit more money, get a custom tune, that will show exactly what your vehicle's engine is doing and what it needs to make more power. BlackBear will send you equipment, it'll log everything your vehicle is doing, the air/fuel mixture, etc, and in turn, they can custom tune for EXACTLY what you need.

I wasn't even planning on tuning my truck. But once I realized that a Black Bear Performance tuning meet up was going to be close to where I live I jumped at the chance. Really glad I did, and I have no regrets whatsoever.

Like the OP, I too cannot afford a BB tune. I would like to get rid of the lag between pressing the accelerator and the engine actually responding. It's my biggest pet peeve in my 07 Denali XL. I actually use T/H mode around town sometimes, or if I know I'll need to merge with traffic quickly.
I have seen a device that plugs in between the pedal and it's connector, and it even has a switch to change sensitivity, so the accelerator acts more like a linkage than a drive by wire setup. Anyone heard of/use this?

It seems like all you need is the Range AFM disabler.

No , never heard of that....
range helped me out with the same problem...
Also, and im being serious, clean your throttle body...it will help too

I am getting that diablo tuner. i2030. i can keep retuning it if I want.

How do I find out if my Denali has AFM?

 

[PG01]

What year?

 

[dirtydenali07]

What year?

2007.

 

[PG01]

Ifs is a 6.2l i dont think so i think that started on them in 2010. 5.3's way before that. Look at the dic and look for v8 mode which should be with mpg crap if it has it it'll switch from v8 to v4..im not exactly sure, someone may know better

Blackbear seems to be all the rage. Everyone that I have seen who sprung for the tune, has had absolutely NO regrets. Their tune, on an otherwise stock truck, has apparently made very noticeable improvements. The scan cable tune datalogs YOUR vehicle, so when they get the file, they can specifically adjust it for what works best for your vehicle. It's cheaper than a dyno tune, although that would be the most optimal method of tuning. Ofcourse that also explains why it's the most expensive method.

A handheld tuner won't be much, is any cheaper, and like Nathan said, will give you a generic tune. Basically a tune that can safely be used on every other truck made that year. The Diablo Sport can apparently be used over and over, and also be used if you decide to have your truck dynotuned.

I don't have the same issues that you are trying to adjust, as my Hoe is a 96. I need a tune to adjust for my heads and cam, and unfortunately pre-98 vehicles cannot be dyno tuned, nor is the Blackbear scan cable an option. I'll have to order their standard tune, until I can 0411 PCM swap mine.

How do I find out if my Denali has AFM?

Well, if you have some time on your hands, I would suggest decoding your RPO codes. Perhaps someone with AFM already knows the RPO code with the assistance of google (be advised, this can be a time consuming process, but it's free and tells you every option that you have on the vehicle), and you can take a quick glance to determine if you have it.

Another option, posted in the 91-99 section, for $5 there is a company that will decode your RPO codes for you, and get the results right away.

Well, I gave up and paid the $5.00 for 5 vin decoder package with

http://www.compnine.com/vid.php,

got it right away. I need it to verify the RPO on the vehicle before I bought it.

I've gone through every menu on the DIC. no mention of V8 nor DOD/AFM.

 

[dirtydenali07]

I just did a search and found this on GM Authority
http://gmauthority.com/blog/gm/gm-engines/l94/
It makes it seem like all 6.2 has AFM.

If you dont see that on the dic you dont have it, it has to let you know when in v4

 

[dirtydenali07]

That's good to know. I've read on here about lifters for AFM failing.
