Deconstructing the Lightning: Using AI to Map PIDs for Torque

[Firn]

As the saying goes, if it works don't fix it.
I thought you were looking at options because you weren't satisfied, but if it works for you that's all that matters.

Unless of course we all decide to pool our data into a giant, common, database - now that would be pretty cool !

The thought is on my mind. Part of my redesign is to enable multiple vehicles and different (changing) configurations per vehicle (tire size, towing, etc) Not sure if it could scale appropriately, or how to host it, but the concept would be cool.

I may have missed it, but is there a list of PID's we have/need?

Ok, that looks familiar. I think I used that list for my copy of TorquePro. I'll have to look through it again later tonight to remind myself what's available. I primarily just use it to look at charging related stats.

) but it is also different when the truck is left on (which I assumed the guy doesn't since he's charging at work).

Actually the truck was left on. We have a secured facility; nobody messes with anything. I had the heated seats and steering wheel on so I could come do a warm up every now and again as it was pretty brutal outside. Plus I had the Pro Power on to charge a couple of power tool batteries.

So; if the truck is left turned on, it delays charging until the battery hits 68F?
Forgive my ignorance, I am still less than a month into my first ever Ford anything.


What are you using to capture this logging information and can it log charging data with the truck switched off?

When it is super cold, will the AC charging commence faster with the vehicle switched off?

It still takes a charge but at a slower pace, which more noticeable when DCFC charging.

I read through it. Apparently the pace with the 32A Ford charger was so slow it showed up as no progress at all. After an hour to 2 hours it would start to progress.

I have done some more logging and here is the consolidated list. These still need to be validated.

Copy into a text editor or excel to turn into a csv. (note, excel takes the header value and converts a bunch to scientific notation. To fix it use the text import and set that and the PID value to Text, not general)

Conv Low Current,CONV_LO,22D118,(A*256+B)*0.01,0,100,A,7E4,BECM: DC/DC Low Current

I'm a little confused about these. Is this a min/max current available for the LVB? Also, I don't see current voltage for LVB or the HVB, but I have those (I think from the PID list linked your other thread). I can double check that when I break for lunch.

I have no idea where @Firn got that from but those are not correct.

220582 is a coolant pump (A) duty cycle
22D118 is the motor current from the steering rack, frunk or tailgate servos (depending on which module your're requesting it from).

The current to/from the DC/DC converter is 224836 (12V / LV side) and 22483A (HV side), both should be 8-bit and 0.01 resolution, directly from the DCDC (746) module.

These are raw from using forscan to log and wireshark to monitor the message traffic. Gemini is then trying to reconstruct from the bits into the PID used and the equation.

These are of course raw from it and hence the need for validation

Don't trust the AI not to scramble your data! It will randomly change things and just make stuff up. I

I give it to CGPT then Gemini then back again and so on and have them check each other's work.


Eventually if you can get them to agree it is usually mostly correct. Sometimes. lol
