Passed!

Cause they changed the programming.

Handling is not a programming issue but a suspension issue. Any reprogramming will have zero impact on how the vehicle handles.

Mine passed too and has 39k on it. I had already switched oil as soon as the notices started coming out. I am kinda bummed bc I had planned to add the supercharger kit to it but now have to play it safe and not go that route.

I'm still throwing my whipple on next month. Took it in to Stevinson and the SW said there was no extended warranty for mine, "warranties after the recall get handled on a case by case basis"

I pass 5 other GM dealers to go to these guys for my service but not anymore.

You gotta break 50 mph before you can talk about handling tho. Mine handles differently when the Range module was installed, it handles differently when I'm in tow haul mode, it handles differently in 4x4, and it handles differently when I'm banging on the paddles at higher rpms. All of which are controlled by a vast amount of electronic sensors, ECU programming, and driver inputs........change the parameters, get different results.......engineering 101!

The suspension is not electronically controlled. I guess it depends on what you consider "handling" to be. To me, handling is 100% suspension related and has nothing to do with the ECU, TCM, etc.

Yeah, we definitely have a different perspective, cause its the chassis, its the axles, its the bearings, its the driveline, its your tires/wheels, its your seats, it's your steering stem, steering wheel, and its your steering linkage.....and on and on.

I guess I've drove and modified so many things in my life, I've come to realize even the simplest things can change how a vehicle performs. I never rejetted a carb or an reprogrammed an ecu and didn't feel a difference in how the vehicle "felt" or "handled".

I can guarantee you my truck handled differently when I left the dealer after the new ECU and reflash, especially with the DFM module removed. The transmission also has to relearn the if the ecu programming has changed at all. But it doesn't last long, now it just feels "normal".

You "feel" everthing if you're that guy. If you're not, thats OK too.

There is a HUGE difference between "driving" differently and "handling" differently. You made my point above as what you're referring to is the drive and not the handling

I knew exactly what he was asking.
Yes, it handles differently when the programming changes...........once everthing syncs up, it's business as usual.

Are you a mind reader? It "drives" differently when programming changes. It "handles" differently when you change tires, shocks, control arms, anti-sway bars, lift kits, etc. Programming does not affect handling no matter how you want to spin it.

We established you're not "that guy" a few posts back tho!

I got two identical CRF450RL motorcycles with two different ECUs and tunes. Both handle differently at different points in the powerband. I'll take the one on the left down low and lower speed with better torque, I'll take the one on right for higher rpms and speed when wringing it out. Mainly due to the the programming, then you adjust the other parameters like suspension and tires to round it out.......simple stuff.

If you ever tune that grandpa rig, you’ll find out right quick how tuning dictates handling........but I dont think you have it in you.

I don't believe post #17, which started this conversation, has anything to do with an ECU update or all that was done "programming" wise was stopping the rear wheels from locking up and nothing more in addition to an oil change and a gas cap. I will say it again, and the final time and I'm out, an ECU tune will impact the driving experience but NOT the handling unless you continue to feel that handling (suspension related components) is impacted by the ECU...which they are not. It appears we have different definitions of the word handling. If I kept trucks longer than 1-2 years, I may consider spending money on the suspension and a professional tune. However, to spend all of that dough (thousands and thousands) and trade it in with 15K - 20K miles and get nothing more for all I sunk into it makes very poor economic sense.

 

[AXE]

You need to get a handle on your arguments.

The answer to post 17 was simple, and I answered it correctly. Yes reprogramming will affect the input parameters, which will affect how the truck performs....."handling".

In this case, its most likely because the ecm and tcm need a bit of time to sync back up. That'll resolve itself relatively quickly. Then your rig drives how it drives.

You can't handle the truth!

Again, a trucks performance based on ECU and TCM changes are not handling, it's drivability. Performance is NOT handling. You need to better understand the difference between drivability and handling. If the DSSV shocks had electronic sensors that changed the handling of the truck based on various inputs and conditions, I would say you are correct. However there is nothing that changes the suspension (i.e. handling) of the truck based on programming alterations. AXE...it's ok to say you made a mistake and stop fighting the obvious. No one will think any less of you my friend.

 

[The_Q]

I’ll add my two cents to this discussion. The sixth bullet point below, in my opinion goes along with what @AXE has been saying.

Is handling part of the driver experience https://www.google.com/search?q=is+...wgwLjIuMzAuNsgH8wE&sclient=mobile-gws-wiz-hp#
AI Overview


Yes, handling is a significant part of the driver experience. It is a broad term that describes how a vehicle responds to a driver's inputs and how the driver feels while operating the car. Good handling makes a car feel responsive, predictable, and stable, which increases both driver enjoyment and safety.
What handling includes:
Handling is influenced by many parts of a vehicle, all of which contribute to the total driver experience. These components include:

• Suspension: This system's design affects body roll in corners, the car's responsiveness, and how it absorbs bumps.
• Steering: This includes the steering ratio and the feedback the driver receives from the road. Responsive and communicative steering provides a strong connection between the driver and the vehicle.
• Brakes: The brakes' stopping power, pedal feel, and ability to work effectively during turns are all part of the handling experience.
• Tires: A car's tires are its only contact with the road. Their condition, size, and tread pattern directly affect grip, stability, and responsiveness.
• Chassis and weight distribution:A car's center of gravity and overall weight distribution greatly influence its cornering ability. A lower center of gravity and a balanced front-to-rear weight distribution often result in better handling.
• Power delivery: The way an engine's power is delivered to the wheels also affects handling, particularly when accelerating out of a corner.

Objective vs. subjective experience
Vehicle handling has both objective and subjective elements for the driver.

• Objective: These are measurable aspects of a car's performance, such as cornering grip (measured in G-force) and how quickly it responds to a steering input.
• Subjective: This is the "feel" of the car—the driver's perception of how predictable and fun it is to drive. A car with good subjective handling might feel like an extension of the driver, inspiring confidence. For example, the Mazda Miata is often praised for its "fun handling" rather than its outright performance metrics.

Like I said, its all a connected system to me and responds according to the numerous variables and inputs.

I answered the way I answered, simply cause mine drove like shit for the first several miles after the new ECU, programming and removal of the DFM. I almost turned back to the dealer after the first couple miles. Then after about 5 miles it was better, then pretty good by the time I got 20 miles back home. Then put the DFM module back in and a couple short drives later it was "normal".

To me the question was never about suspension, cause the whole thread was about the recall and the ecu flash, so that's what I reported.
