Throttle response on 6.2...

[bdbake01]

Just fyi, all the Sprint Booster does it modify throttle position signal before it gets to the ECM. So for example, if you are at 50% real life throttle position it will alter the signal and tell the ecu you are really at 75%. So its really a placebo effect at making you think you are accelerating faster than you really are.

Which...I can also do with my foot.

 

And buy $300 worth of beer. That's a LOT of Steel Reserve.

again, a custom tune, hell even a canned tune will fix this. it costs 300-600 for a great canned or custom tune and you will never post this question again. you'll also make up the difference in gas mileage, if you can keep from listening to the tires squeel.

How long does it take to mash the pedal to the floor? Not long for me. If I want to go quickly, it will respond immediately with a little push of the accelerator.

[SoonerDPT]

I don't want to have to mash the pedal to the floor to get it to go. That's why I don't drive my girlfriend's 4 cylinder Nissan.

A few things I picked up on in this thread.

 

Evidently someone in authority from Diablo made a statement on the Internet about not being detectable once their tune is removed . They specifically were addressing a concern that GM might deny warranty coverage if their tune was detected. This Diablo representative was making a claim about their product. That would be a good basis for a judgement against them if GM did indeed discover the tune and denied warranty. But it also says something about their ethics. They are willing to advertise their product can help someone be dishonest in a warranty claim against GM. Hmmmm. Do I really want to do business with them? Are they going to accept responsibility if their product is faulty?

 

Also, everyone seems to know the ground rule that tuning will likely lead to a warranty claim denial if something goes wrong with your driveline and the tune is discovered. More specifically, if they trash the trans or engine. Some people are interested in how to avoid detection of tuning in order to keep from accepting their responsibility.

 

It's no surprise to me that GM and other makers are seeking protection of their coding. The warranty claims against them for these situations eat at their profits. Why should they take it in the shorts?

The throttle DOES NOT adapt.

 

Shift points DO NOT adapt.

 

Shift times/speed DO NOT adapt.

 

The ONLY adaptation is shift pressures required to complete an upshift or downshift. This is in place to maintain correct feel for shifts over time.

 

If you want to change any of the above criteria you need a tune.

Well this certainly sucks. I'm gonna have to revisit the security on my garage. Clearly my fairy god mechanic has gotten in again and he changed out the stupid computer that my truck came with with this much better version. That's the only possible explanation if the computer can't adapt.

[Higgs Boson]

there's a much better chance your brain adapted instead.

 

I spend an inordinate amount of time in people's ECMs and TCMs altering calibrations in exchange for US dollars so I am sure that whatever your interpretation is of whatever someone told you at some point in your past that was their interpretation of what someone else told them in their past is correct and I am not.

 

throttle response is not adaptive. sorry to let you down.

[KARNUT]

Between the wife an I we have four vehicles, a sports sedan a sports car a custom truck and the GMC, I have no trouble adapting to their different styles when I get behind the wheel of each. If they all drove the same that would be boring as hell.

Nice. Well since we are comparing the length of our...ehem...resumes, allow me.

 

• Rebuilt first engine at 10. It was a 5hp Briggs on my go cart.
• Rebuilt my first V8 at 12. 350 in a 1976 Malibu. Cracked head, time for refresh. Admittedly I had to try it a few times, but I eventually got it right. Still running, well cared for.
• Reprogrammed first GM vehicle in 1991, at the ripe old age of 15. It was my S10, couldn't even legally drive it yet. Still have that truck.
• Swapped TBI on said S10 and added an S-Trim charger w/ custom intake at 17. Programmed an Edelbrock ECM to control it all. Never dyno'd it...but it was a beast on the st. Amazing I didn't kill myself. Put down a few Syclones.
• Can't count the # of engines, trannys, etc. that I've rebuilt/replaced/etc. over my life
• Transplanted an LT4 from a '97 SS into a '94 Firebird
• Pulled a blown LT1 from a '93 Bird, auto car, and replaced w/ a junkyard LS6, also auto, but swapped in a T56 and new manual ECM + harness. With my code.
• I've reprogrammed no less than 80+ LSx based vehicles or their derivatives alone. Engine/tranny/etc.
• 3 were pretty wild turbo LS's, one was twin w/ nitrous
• Programmed several aftermarket controllers as well. Full engine, tranny, spark/fuel only, etc.
• Every vehicle I've EVER owned, with the exception of the Sierra, has ran my code.
• My '99 TA has never had the heads off, yet it puts down roughly 450+ on my code and can still get ~30 mpg highway. City is...ugly. It's got a converter...whatchagonnado?
• Licensed Electrical Engineer, controls is my specialty
• Most of the vehicles you have driven from the Big 3 were either assembled, painted, or both by robots that I designed, programmed or installed. Or all 3.
• I've automated literally 1,000's of control systems, of any type you can possible imagine over the years. Heck, even my fish tank is fully automated with an arduino.

Full disclosure, I've never plugged into a K2. Life's priorities have changed a bit, and I just don't have time to fiddle with it anymore.

 

I must respectfully disagree. Your turn.

[bdbake01]

Oh, and I believe what I see, and I question everything which I hear.

[Spurshot]

Time to call for a measurement.

 

...or I can just go back to bed.

We aren't comparing anything. I didn't read your "list." I don't care about your list, both of our lists are irrelevant. In fact, your extreme reaction to me stating a simple fact that really has nothing to do with you except that you previously stated otherwise tells me all I need to know. You are going to to defend yourself without facts. Sorry, I don't have the time to list my personal resume, plus, I'm not 10 years old.

 

 

Oh, and I believe what I see, and I question everything which I hear.

 

Unfortunately, you can't see your throttle activity, you can feel it. And while a singular perspective is highly unreliable, what one feels is open to even more interpretation. By the way, what you are doing right now is called reading, not listening.

 

Post some screen shots of your calibration. Post a link outlining the adaptive throttle response. When you do that your opinion will gain credibility. Otherwise, all you have said thus far is, "My truck feels more responsive after I drove it more." I will not take anything away from your opinion. You feel that way. Nothing wrong with that. All I am saying is that the more responsive feeling you have is not due to adaptive throttle.

 

Again, post some PROOF. I am not at my tuning laptop right now but I can post any piece of factual information about a GM calibration you want to see. Just let me know. I am here to help.

Like I said, most everything related to these trucks on the forums is opinion. No one knows for sure if GM will deny a warranty based on a tune, because no one with a tuner has had to file a claim. The owner of Diablosport did say in two forums including here that his tuner was not detectable after the tune is removed, and that he has a GM employee(s) to ensure it works this way with the CVN counter.

 

Aside from that, if you decide to not purchase their tuner because you feel it is shady or sneaky to try and get past GM the don't. But don't hold them to a higher standard than people who root their phones, jail break them, buy a tuner to remove the speed limiter or any other countless things we do because some manufacturers lock down the products we buy because of government safety regulations and to prevent lawsuits.

 

Kinda reminds me of people who fight speeding tickets that are less than 10mph over. They are still speeding, but the judge will write it off anyway because its such a "minor" offense. If you're gonna be black and white, you should be that way about everything

If GM calls for the checksums on your ECM/TCM/BCM/CCM due to a powertrain failure they will absolutely not honor your warranty claim. They are not going to check and report every time you get an oil change.

 

There have been tons of instances of denied claims due to a tune. There have been threads posted with proof of detectability with pictures by GM techs pulling the checksums.

 

This all started with the diesel guys tuning their trucks to 1000 ft lbs of torque and blowing transmissions and has migrated over into all of their cars. GM has produced literature, owners manuals, TSBs, etc that specifically state a modified calibration will not be eligible for warranty repairs.

 

We DO know GM will deny a claim based on a tune.

If you modify your car and it fails don't expect the manufacturer to fix it for free. That's pretty stupid!
