    I know I've been posting like crazy on this stuff, but man, I've been hoping someone would get this working for a long time. So please excuse the excess traffic.

    OK... I'm pretty much done with my XGauge hacking for the time being. What I've managed to piece together is pretty neat. I've attached my latest drop.

    1. SOC and BTA on the same gauge!
    2. Speedometer with a decimal point precision.
    3. A gas gauge with 4 times the precision of the "guess gauge"
    4. Realtime RPM (no half second delay on the SG refresh).
    5. Coolant temp with half-degree precision.
    6. Gas pedal position indicator (0-100% depressed).
    7. Brake Pedal position indication (0-100%).
    8. HV pack temperature gauge.
    9. An "ON/OFF" gauge to know if the EV button is "ON or OFF"
    ​
    I'm hoping someone else can pick up the torch and find MG1-rpm, MG2-rpm, and inverter temp.

    Dan this might be beneath you to answer, but I have a scan gauge now but have no idea how to program these nice gauges in? Be there a reference somewhere?

    You want to look up XGauge editing on page 25 of the user manual. It is on page 27 of the pdf.

    Kudos.

    Glad my earlier thread was slightly useful :)

    Now could someone figure out why I can no longer get anything for "tank--to empty"?

    I used to get a reading and now it just bounces back to "current". I have e-mailed the SG people 3 times with no response.

    Certain "Active" gauges can't be used at the same time. Try changing the other 3 gauges to something else.

    I suggest liberal use of "reset factory defaults". On the way home yesterday, my "CURRENT" mpg registered a 52, where I'm normally in the 80's. I suspected one of the passive gauges so I cleared them all before heading into work this morning. Well about 3 miles in, I've got current mpg up and I watch it drop (over one-second) from 78 to 27. The 27 stuck and the glide worked that number back up to 50 by the end of the glide. So I then did a factory reset and everything cleared up ok. I've slowly started adding gauges back and all looks well.

    I suggest that you play around with the gauges until you get a "proven" set. Once you have that, clear them all and perform a factory reset. The after a few miles on a "clean gauge" add the "proven" ones back.

    I'll let you know if I get any other random drops in MPG. This is why I always check my SG numbers against my FCD.

    I have pushed every frickin' button there is and reset it several times. It also lost most of the colors after it's "upgrade"

    Since my year of service is coming to a close, I am going to try and send it back.:mad:

    Just found [post="541193"]SOURCE CODE[/post] following on Atilla Vass's work. Now I can really get busy.

    Yikes... sorry to hear. If your still interested, setting the TXD field to blank deletes the XGauge.

    I just picked up my Scanguage II today. Will the XGauge data you provided work with my unit? Is it as simple as adding in the TXD, RXF, etc. like I did for the SOC numbers supplied in the user manual?

    Yep, add it just like SOC.

    Ha, I knew your last name started with B! (Only nerds will get that).
    Hope you don't mind, but I referenced some of your work in my (hopefully) user friendly user manual which I posted in another thread, both here and at CleanMpg.com (which has a lot of good threads on the SGII).

    Dan,
    This is really sweet, thanks for the hard work. :first: I've been looking for the Bat temp. The engine and catylitic temps are pretty sweet too. One thing I'd be interested in seeing is the amount of physical braking. Bat current is one of the things I watch, but seeing when the friction brakes engage as opposed to the regen braking would be cool.

    Have you been using the fuel guage? Does it work any better? It seems the problem w/ the guess guage is the bladder, I don't see how the scanguage is going to do any better, but if so I definitly want to here about it! :cool:

    Jeremy

    Lots of us never get tired of your Scanguage updates! I look forward to them as I just sit back and enjoy them while you do all the work!

    I'm working on MG1 rpm and MG2 rpm currently...

    Braking might be possible but I haven't dug through it yet.
