I did.... shifted like garbage. Not enough adjustability for that stuff yet to do anything like that. That's 8 speed though... 6 should be no problem to do whatever.

Yeah mine shifted awful to and Justin has tuned on mine for a while now and turned it off and I was amazed at what a difference it makes. I was wondering how many has done so when tuning the transmission.

I have done some minor tuning on my 20116's transmission. I reduced the upshift times by 30% and the downshift times by 35%. I turned off the upshift and downshift torque management and the truck shifts almost perfect. It will have to do until HP Tuners releases the pressure tables. As of now it is firm on every shift and gets after it on the shift time side. To be honest I could probably reduce the up and down shifts by 40% and it will be perfect.

 

I wish GM would take some cues from the Germans. My wifes Audi has a 8spd auto in it, under normal drive mode it shifts quick with no delay at all and just some slight firmness. Put into sport mode and the shift times are reduced in half and in snaps the shifts in place each time.

LOL on the European Builders.... Hell my wife's Honda Pilot and my Daughters Civic shift better than the truck did until this last change and they are both Merican made!

Instead of digging through 57 pages, I'm hoping someone can answer my question. I'm thinking about picking up a 2016 w/ the 8-speed. I have HPT with an available license. Are there any components that I won't be able to edit with the tune? Is the 8-speed fully supported with the newest version of HPT?

I have HPT and upon recommendation of how much of a buggy pos it is I haven't upgraded to the latest.. they were supposed to increase 8 speed support though which I want too. But in 2 weeks time they have revised the 3.2 release 25 times and it's still causing guys issues... so I will wait a bit longer. The current 8 speed stuff isn't hardly worth playing with.

My 2014 5.3 silverado has a supercharger kooks headers kooks exhaust and a cai and pcm dyno tuned my truck made 540 and 560 at the crank truck. Long story short my stick piston rods broke and came thru the block. My mechanic said the truck was running way to rich and pistons lost the lubrication due to it running to rich

Been a the shop now putting another 5.3 in it and adding supercharger and headers to it until I have money to built a a vette ls3

Yeah, making nearly 600 hp is one thing. Getting the beast to live a long time is another. Don't ask me how I know haha. Sorry for the bad luck man. Oh and btw old broken internals make for some good furniture and accessories for a man cave.

    • That makes sense, and I think you are describing the real product problem. Capturing data is the easy part. If the owner or technician has to manually dig through five minutes of millisecond-level logs, the product has already failed. The device would be at the ECM harness, not at the OBD port, so I agree that data retrieval and event marking need to be thought through carefully. The way I am thinking about the architecture is: The recorder itself should not depend on a phone, app, Bluetooth, Wi-Fi, or cloud connection to capture the event. It should always keep a local rolling buffer and lock the event locally. A button, phone app, or small cabin device would only act as an event marker. If the driver feels a stumble and presses the button 10–30 seconds later, the pre-buffer has to already contain the useful data. For data retrieval, the practical options would be a sealed service USB lead, Wi-Fi download, or a phone/cabin companion device. I would not expect the owner to remove the ECM-side module or work with raw files directly. The cloud or AI side would be for interpretation, not for capturing the event. The truck may have no connection when the issue happens, so the evidence has to be saved locally first. After that, cloud processing could help decode the data, compare it against baselines, and generate a readable report. For the first version, I would keep the automatic triggers conservative and objective: driver event marker bus-off error passive voltage drop / brownout device reset FIFO or queue overflow a normally periodic message disappearing side-to-side communication mismatch, if the topology supports that For “learning normal,” I agree with your point, but I would not want to overclaim it as automatic root-cause diagnosis at first. A realistic first step would be learned baseline comparison for that specific vehicle and operating condition. For example, a value would only be compared against similar conditions: RPM range load / MAP throttle position gear / vehicle speed coolant and oil temperature battery voltage AFM/DFM state, if decoded and validated Then the report could flag things like: this periodic message disappeared compared with its normal timing this value deviated from this vehicle’s normal range under similar conditions the same abnormal pattern repeated after the same type of event the anomaly occurred together with voltage, oil-pressure, misfire, or communication changes But I would still call that “abnormal pattern detected,” not “replace this part,” unless there is enough validated repair data behind it. So the intended product would not be “here is a huge log.” It would need to be an event package: what triggered the capture how much pre/post data was preserved what changed before and after the event whether the device itself reset, overflowed, or saw a bus error selected graphs around the event raw data only as supporting evidence From your perspective, what would make this kind of report useful instead of just another datalog? For example: What are the top 5 parameters or events you would want highlighted first? Would you trust a learned baseline for that specific vehicle, or would you prefer fixed thresholds? How much false-positive flagging would be acceptable before you stopped looking at the reports? What would a one-page report need to show for an independent shop to take it seriously? For misfire, AFM/DFM, oil pressure, or U-code complaints, what would you want the tool to flag automatically?
