ScanGauge II on a Prime, still useful?

Oklahoma City, USA?

 

I am in a similar situation: I own two Scangauge II which I use with satisfaction with my Lexus RX450h (MY2010), In prevision of the arrival of my Prime, sometime ago I sent both units to Germany for the firmware upgrade (basically my Scangauges mothernoard was replaced with a new one) so I am ready.
Let's hope that some Xgauge guru will discover the Prius Prime specific Xgauges soon (SOC and AMP primarily, but also BATTERY TEMP and MG1/2 TEMP are to be considered.

 

Aren't even the built in scan gauge functions subject to being out of date, with a new gen? Not sure.

 

I have the Carista OBD adapter (bought to update the settings), and then bought the app "OBD Fusion" as it got the best of ratings on the App store ... while it does communicate with the Carista, some parameters work, others don't. Have not had the time to get into the detail yet though but if my interest peeks again (and i have the time) i might tackle it again

 

If the Prime is the same as Gen 4 than Scangauge firmware 4.22 or later is needed for the xgauges.

What about the battery current? Where Bta would be back on my Prius c, the Bta X-gauge shows up as blank on my Prime, so which should I use? As far as I can tell, my firmware is up to date version 4.43

 

The Prime should use the Gen 4 Prius codes. The Prius c would use the Gen 3 codes. Some are the same and some are different.

Here are the Generation 3 codes. Even though the Scangauge site says up to 2015, newer Prius c & Prius v use the same Gen 3 codes.

pay attention! when the three dots rotating in the far upper right side are showing up and continue to rotate just hit refresh on your browser. your post will show up eventually

 

This one didn't work when I tested my Prime:

Hybrid Battery Voltage (Volts) for Gen 4 Prius

 

When I found my second ScanGauge-II (which I purchased on eBay) had old firmware, I called Linear-Logic to arrange an upgrade, and LL said just give us your mailing address, and we'll send you a new chip for free! …so I did just that they did just that, and within a couple of days, arrived in the mail a new board, which was a doddle for me to swap (my original training was in electronics, and I was quite familiar with small circuit-boards and soldering etc. etc.) - so here's a shout out for Linear-Logic! So both of my SG-IIs now have the latest firmware and LL didn't charge me a single cent!

 

I do that and occasionally it double posts anyway
Thanks for the reminder though.

 

On my Prius c, I set my ScanGauge II sleep even to COM, so that when I keep the car running, it would stay on, and would turn off only after I pressed the power button on the car.

With my Prime, ScanGauge II does not turn off when sleep event is set to COM. Changing the sleep event to VOLT, ScanGauge II will sometimes turn off when my Prime goes into EV.

Anyway to fix this other than getting into the habit of physically connecting/disconnecting the cable? I worry that one day I'll forget and it'll drain the 12V battery.

Also, any word on how to get the traction battery voltage? (Gen4 codes didn't work for me)

 

You can try these, but they are likely PiP, not Prime. It is difficult to tell because Prime is named PHV elsewhere.

Prime is quite different from PHV. None of the handy pids on my scangauge worked on the upgrade. Sadly, the ones haven't been made available yet either. Knowing things like motor RPM and battery temp can be very informative.
