PID List to Monitor your Lightning

[Jiji]

Back with one more question. I looked through both the spreadsheets and ForSCAN looking for the module address to read the GOM/DTE (distance to empty) and came up blank (expecting it to be in the IPC as it is displayed there). Anyone know if this exists, and it yes, how does one access it through the scan tool port?

My use case is to compare the miles driven vs the change in DTE in my driving dashboard to flag when range is being consumed faster than expected. For example, if you drive 10 miles and use 20 miles of range then you likely have to charge sooner than expected.

Not to turn this into a GOM thread, but that value is so worthless I'm not sure anyone went searching for a PID on it. FAR better to set a trip meter, monitor your efficiency, and do the math in your head.

Or just use ABRP.

I have never found the Ford calculated distance to empty to be anywhere close to correct (not to mention the discussions here). The last time I charged to 100% it said I had 345 miles of range, which just cemented my mindset of never relying on that number.

I believe all the stuff the OP is interested in is calculated real time in the IPC and not transmitted. A year ago I wanted to make a more accurate GOM for the community, which would be easy if we had access to "this trip" efficiency. But I couldn't find ANYTHING about this trip. That's when I assumed it was all calculated in the IPC and stuck in the IPC. I'd love to hear from someone familiar with the analogy of this in the ICE world. Ya know in most ALL ICE vehicles, you can look at a running MPG or instant in the IPC. The instant is certainly available as a PID, but the OBD port isn't near fast enough to integrate that data and get any accurate result. I'd love to hear if any ICE vehicles offer more efficiency info over PID than the instant.

it is an iOS phone companion app for the Lightning and Mach-E so these aren’t useful suggestions.

The GOM can’t predict the future so over the longer term. It is less accurate since it doesn’t know if it’s going to be cold and raining tomorrow, or if you’re going to be doing more climbing than descending, or if you’re encountering headwinds or tailwinds.

But my use case is over the very short term since I am interested in quickly observing that the difference in the distance to empty is deviating from the actual distance driven. Like this Rivian dashboard that highlights how off they can be.

It is the FordPass API and probably isn’t too hard to calculate from the EtE PID (Energy to Empty), maybe Ford just applies a correction factor based on the mean monthly temperature to estimate the range.?

And the trip efficiency in kWh/mi is just the delta EtE divided by the distance travelled in miles. Pretty noisy signal so some sort of averaging makes a more interesting display.

I have noticed the "this trip" efficiency in the Ford Pass app too, so true, they are getting it somehow from the IPC to the Telematics module (possibly via ethernet). I have also considered it could be calculated and stored in another module like the PCM (would make more sense for accuracy), but I still believe it is done in the IPC just out of tradition. I use the Trip 1 reset often to get a good average efficiency when I'm on a highway or consistent long route. It works just like a traditional ICE in that you can reset anytime and the average starts integrating indefinitely from the reset. The fact that I'm 99% sure this is calculated/reset/controlled within the IPC, tells me the "this trip" is also done there. Also, we can't get the Trip 1 or 2 info from the IPC,, WTF Ford. It would've been so easy for them to program PID's for all this info, but I don't think they have traditionally in ICE either, unless someone knows different. @Martin Rebuilds ?

Also, isn't it bizarre how they choose not to list (or allow to see at all) the instant efficiency for the driver, WTF. This has been a hard staple in the ICE world since emissions standards started. It's like since it's an EV they feel they don't have to follow any of these standards, but then they give it to us in the PID list as a standard,, and feel they have to keep other standards like a big clunky shifter,,,,, SMH Ford.
