In the market now to pick up something to disable the DFM on my L87. I know the pulsar has been the go to option but I see some new hand held tuners that have piqued my interest. 
 

Anyone go after one of these new handheld programmers?

Edge, Diablo, Superchips

Edge/Diablo/Superchips are all on a modded ECM exchange.  You can't just get the tuner and boom done, you need to swap your ECM with them as well.

 

Pulsar is just an inline plug and play device, no ECM swap required.

Yep done some research on them with the exchange ECM service. It is what it is. 
 

Are you running a Pulsar?

I am running one for a couple weeks now, can I answer any questions for you?

With everything setup, have you noticed any changes in the trucks behavior once selecting sport mode? Say throttle response set to 3 on normal mode and switching over to sport mode does everything carry over and once in sport mode even more aggressive?

Yes I run it on 3 actually and YES sport mode does what Sport more usually does, holding the rpms etc for shifting, myself it is a bit too much for my use with this truck if I use that combo.

I have found no negatives really from it the auto start stop is nice not too think about I have not done a thorough test on mpg difference on the highway with dfm active vs deactivated, however in my preliminary testing I was getting better with dfm working.

Which I know no one wants to hear...haha.

Sounds good. I’ve got to get rid of the DFM and the helicopter noise. I wonder if the fuel economy has decreased because of the increased throttle sensitivity?
 

Thanks for the feedback.

I am trying to be "normal" with my foot as that can be however the prelim test was highway driving thus far.

My plan is the exact rt with cruise control both directions one dfm active the other inactive same speed over 40 miles each way, as we know city mpg has too many variables.

I have gotten 24mpg consistantly on trips with this truck in AZ and Nevada at 74mph with dfm still active.

I've had a similar experience like Robby, good response and too many horror stories with the AFM to not hedge that bet. However, my experience with MPG is quite opposite and mine has gone down. I have the 6.2 with 10sp and it has made my day to day driving much more enjoyable. I do a lot of city driving and likely have a heavier foot than most. I don't use race mode on mine but keep the Pulsar at level 3.

For me the Range was fine but would have had to combine it with the in-dash auto start/stop disabler and Pedal Commander. I pulled them out and replaced with the Pulsar. Individually, they all worked as advertised but wanted a cleaner solution.

 

@MikeDP What is the helicopter noise you are referring to?

Right now the cluster is showing 17 mpg at the 400 mile setting. Mostly highway. I have the Rotofab intake and Borla S-type catback with quad tips. Factory setup 6.2 10 speed boss with 18’s and Duratracs.

I can’t stand the DFM now that I can hear it with the intake and exhaust. Even in sport mode the throttle is too relaxed for me. (Came from a BMW)

 

When cruising down the highway you can hear/feel a different noise and more vibration in the truck as it’s going down to 2-3 cylinders. When I select L9 it is constant V8 mode and no odd noise. 
 

I bought a 6.2 not a Prius.

      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?
