Hi, new here. I searched and could not find an exact answer so I thought I would ask. What is the "normal" idle rpm for the 5.3L ecotec? Mine seems to idle right at 500rpm. I am not having any problems it just seems low.

 

Thanks in advance

 

2014 Silverado LT Z71 5.3L

Cool thanks. Appreciate the info. This is my first Silverado and I started with the 2014. Before that I had a 2011 Suburban LT Z71, 2009 Avalanche LT Z71, 2004 Avalanche LT Z71. All three had the previous 5.3L Vortec and im pretty sure it idled a little higher.

 

Thanks again and glad to be a member looking forward learning more on here.

Really... I could definitely be wrong because in the previous vehicles I didn't pay to much attention. It was a well known engine. I was just curious about the new ecotec. Could there be a difference between the Silverado and the more SUV like Avalanches with the same engine.

Mine is just below the 500 RPM mark, when warm, in gear....

I didn't know that these new DI 5.3's were ever put into avalanches.

They didnt, you must have read wrong. Near the end it was no longer DI specific

Yeah, I was just wondering what normal was for the new Ecotec. The old engine 5.3L Vortec, evidently idled the same I just didnt pay any attention, and at the end I was wondering if there was a difference in say an 07 Silverado with the 5.3 and an 07 Avalanche or Suburban with the 5.3.

 

As far as I know the 2014 Silverado/Sierra was the first application of the Ecotecs.

500 for me. I had it raised to 600 with my Blackbear tune tho. Seems to idle better at 600.

Not a bad idea. I noticed while the truck is just idling and I turn the wheel the EPS pulls a lot of amps and all the lights dim until you let off of it. Obviously not a huge deal, just makes me wonder why lol

Yea my truck seemed to have excess idle vibration at 500 rpm. There was a bulletin that was supposed to fix it, it helped a bit. Once I had it raised by Blackbear to 600rpm, can't even notice it idling sometimes.

      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?

      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?
