JUst zeroed out the slip tables on the TCC, wow it feels so good when I get full lock up now.  Also set the min speed in V4 mode down to 40mph this seems to be a better place to have it activate.

 gonna start increasing my shift point speed , then increase clutch pressures and firmness next.

Read your tune file, it tells you right there what speed you can enable or disable AFM/DoD.   If you don't want it on until 50mph, then put 50mph in the MIN VSS box.   On the PE st

700 was my target point, I played with every RPM in 5 RPM increments to find the smoothest idle. Everything else sucked.

I would read this thread to help understand the settings to change.   https://forum.hptuners.com/showthread.php?75318-Factory-Tstat-and-Control-Point-Question-5-3L-L83&highlight=e92+fans

Did you remove TCC lock up in gear 1-3.  That made a big differnce to me.  I drive arond town alot so I like to leave 4th locking up.

yes, 1-4th disabled, I swear it feels like a higher stall converter, the truck now accelerates friggin fast, and no hesitations anymore  when stomping on the gas. i wish i data logged before and after HP numbers, feels like 15hp seat of the pants

 

I discovered a new window section which list eco mode, i assume is DOD v4, normal,tow, winter, and sport... what is sport mode?, and can i sync it up to a custom trans map via tow haul button something to activate and toggle manually pattern xy,z would be cool!  i know the camaro has this feature, can we splice this into the trucks?

You can set the tow haul mode to shift how ever you want.  I left mine pretty close to stock because I two a big wakeboat.

 

I really don't feel necessary though.  With the right shift pressures it should snap off gears at WOT and still feel smooth at part throttle.

I wouldn’t change the EQ ratio until you have a wideband.  You can get good gains with part throttle tuning using your STFT and LTFT.  Just tune your fuel before you go into power enrichment.

is there a better enrichment ramp-in /ramp out time for the PE table vs stock .050

Any lower than this can cause a fuel dump situation and creat alot of black smoke on the hit when going WOT.  Or at least it did on my truck.  I'm pretty new to tuning but I feel lke I'm picking it up pretty well.  Ask any question you want.

i notice the COrvette file i have keeps the PE  pedal a flat line 70 % while your settings taper off

I tried it with higher numbers at the upper RPMs.  But what found was if you where holding a gear and then rolled into WOT smoothly.  I could create a situation where it doesn’t go into PE.  Had it happen a couple times while I was logging and making second gear hits

 

remember Vettes are much lighter and it take a lot less effort to get them moving.

have you tried setting the rpm activation point to 1200 or 2000rpm? 

 

I also discovered the ramps in /out time prefers a factor of 1.0, and not .050 on stock

 

i am getting confussed on the ECT min max, temps, i will try your numbers , i think mine are backwards.

 

Amaized at how hot the truck gets when i do a pull, i got the cooling fans pretty well dialed  in, but they are always running even at 40% but maintaining my the 178 temp. I wonder if the radiators are a bit undersized for the power output and weight of the truck?

The only time I’ve had them higher is when I was tuning form part throttle fueling  tuning and I didn’t want it to go into PE.

Those PE settings are low, that is going to cause you to go into PE any time you hit the throttle hard off of the line in a part throttle situation. It can cause you to run really rich while in Closed Loop and can eventually fail the front O2 sensors. I keep the PE enable close to stock up until 3k RPM's, then I drop the PE enable to 45% throttle and reduce the RPM delay as well.

 

You dont need or want to be entering into PE just because you goosed it hard coming off of the line.

Can’t AFM be completely turned off as well with a tuner?

yes it can, i just like it active on the highway, its very simple to tun off with the software, lots of vids on youtube giving a full walk thru if needed

i will be increasing my setting higher rpm, my gas milage is around 11.5 mpg. mind you the truck feels so amaizing to drive around town. for a 5000lbs truck it feels like a hot rod now, but its eating fuel like a beast

 

i will also try disabling TCC 1-3rd gear instead of 1-4th, i kinda like a more solid connection in 4th after driving around for 2 weeks now

That’s what I figured. I’d like to eventually have my truck tuned once the power train warranty expires in a couple of years.

for the cost of a throttle enhancer or a DIablo tuner crap, just buy the mpvi and the credits from summit racing  for your truck, there is soo much tweaking of basic stuff that enhances the durability and performance,

      2023 DRW Wheel Liners

      Did have to make 1 modification because of the WeatherTech rear mud flaps and that was needing 3 longer screws than what came with the install package. 😄

      Picked up the liners yesterday. Installed passenger side WITHOUT any modifications. All mounting holes lined up perfectly. Rain is interfering today with drivers side. Very Happy! Will add pics when finished

      OCI, not when but why?

      As a matter of amusement I’ll leave this conversation with this. Do you beat the government average fuel estimate? Statistics are a guide to me. Not a rule. Someone once said I have to have the last word. If true and possible may be. I’ll blame that on working in a family business.

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By bluev8 · Posted

      That is a fair point, and I agree that trying to log “everything in the truck” would be the wrong direction.   There are a lot of modules and a lot of traffic. If the product became a full-truck datalogger, the amount of data would get huge very quickly, and most owners would never use it.   I think the first useful version would need to be narrow: - powertrain-side event evidence - selected high-value parameters - communication / voltage / reset events - pre/post event window - short report first, raw log only as backup   One distinction I should make is between active OBD/PID polling and passive bus capture. If you are polling PIDs through OBD, then yes: the more parameters you request, the lower the effective sample rate becomes, and you are adding diagnostic traffic to a vehicle that is already busy running itself. With passive CAN capture, the recorder is not asking all the modules for data. It is listening to traffic that is already on the bus. So it does not consume vehicle bus bandwidth in the same way that a scan tool polling hundreds of PIDs would. But your point still applies in a different way.   Even if passive capture does not add bus traffic, the recorder still has limits: - processing rate - storage rate - timestamp accuracy - decoder workload - event filtering - report size - user attention span   So the answer cannot be “log everything and let the user figure it out.” The product would need to store enough raw evidence to be useful, but only decode, graph, and present the important parts around the event.   A practical report should probably show: - what triggered the capture - how much pre/post data was preserved - which selected parameters changed - how those values compared to baseline - whether the same pattern happened before - whether any voltage, reset, bus-off, lost-message, or communication fault occurred - selected graphs around the event - raw data only as supporting evidence   So I agree with you. More data is not automatically better. The real product is the reduction from raw data into a useful event report.

      That makes sense, and I agree with most of that.   I think the product would need both: 1. a default powertrain template, so it is useful out of the box; 2. user-selected priority parameters, so the owner or shop can choose what they want to see first.   Different users are going to care about different things. One owner may care about oil pressure and voltage. Another may care about misfire trend, AFM/DFM behavior, or U-codes. A shop may want communication events and repeatability first. Your baseline point is probably the most important one. Raw data is not very useful unless the report can show what normal looked like for that vehicle under similar conditions.   The way I would think about it is: - start with a basic known-good baseline - learn normal behavior for that specific vehicle over time - allow the event to be overlaid against baseline - show whether the event was a one-time spike or a repeatable pattern - provide a simple severity level, but with clear limits on what that severity means   For example, early severity could be something like: - Info: event captured, no obvious abnormal pattern - Watch: value moved outside baseline, but not repeated - Warning: repeatable abnormal pattern under similar conditions - Critical: communication loss, voltage drop, bus-off, reset, or severe repeated event   I would not want the first version to say “replace this part.” That would be overclaiming unless there is repair-confirmed data behind it. It would be more honest to say “this pattern deserves inspection.”   On the OBD port question, I think OBD absolutely has a role. OBD is probably the right place for: - DTCs - freeze frame - VIN - calibration information - normal scan-tool parameters - Mode 6 / enhanced diagnostic data if available The reason I am still looking at an ECM-side recorder is that the failure may happen before anyone connects a scan tool. If the owner plugs in a scanner after the event, the pre-event evidence may already be gone unless the ECU happened to save it. So I do not see this as “OBD versus ECM-side.” I see it more like: - ECM-side recorder: always armed, rolling buffer, event evidence - OBD/DLC companion: DTCs, freeze frame, VIN, calibration, normal scan data - phone/cloud: status, notes, upload, report generation, notifications   I agree that phone connection and push notifications would be useful. I just would not want the phone or cloud connection to be required for capture. The recorder should save the event locally even if the phone is not connected. The phone should help with event marking, download, notes, upload, alerts, and report viewing.   For a default GM V8 event report, would this list make sense? - RPM - calculated load / MAP - throttle position - vehicle speed - gear / torque converter state if available - coolant temperature - oil pressure - oil temperature if available - battery voltage - commanded AFM/DFM state if available - actual AFM/DFM state if available - misfire counters / roughness by cylinder if available - fuel trims - relevant U-codes / communication events - bus-off / lost periodic message / module reset / voltage drop events Which of those would you remove, and what would you add?
