Disclaimer: Ron may smack me... I'm rumor milling here.

Starting this thread to invite the early adopters of the new (yet to be released) SG firmware to post their thoughts. From what Ron (Mr. LinearLogic) said here's what I recall:

Some neat stuff already in SGII

A magic key combo can throw it into "Demo" mode.
You can run it off of a 9v battery if you want to pocket it and pull off data elsewhere.
You can daisy-chain two units together (just think iMPG on one and aMPG on the other).


The first FW rev is attempting to include:

Trip gauges can now be on your 4 gauge display (iMPG and aMPG next to each other)
New gauges - Transmission fluid temp was high on his list for RV'ers.
Custom gauges - Query and response gauges for specific models. Once you get the query codes you can make your own guages to add to the 4-up display. HSD SoC is rumored to be on the working bench.
Possible for-fee firmware-flash upgrade available once the new FW is released. You fedex the SGII in and they FedEx it back to you.


After the first FW rev mentioned above, there is a Second FW rev. This is scheduled to include:

Data logging.
Possible PC (usb or serial) interface.


I haven't heard anything yet on when the (first) new FW rev would be available, but wait patiently. I might just buy a second gauge when it's done. I can't think of any other way to have a SG while the other is off getting flashed. Clearly driving for two weeks without a SG is NOT an option. Once I have two upgraded gauges, I can just give the spare to my Dad for Christmas ;).

We know you can daisy chain them already. Ive waited so *&$%@^%*&^*&)&&(^%# long for the data logging. Ive basically given up on it. then couple that with the fact about 6 of us ordered our SGI's not knowing the SGII'S were to start shipping in a week to 10 days. Kinda makes one feel like you got burned when you look at a SGI and know SGII's were more than likely right there in the box.

With my luck. I will get a unit with data logging 2 days before the one with cell phone and mp3 player launchs.

Custom gauges would be great. I really want battery current, SoC, maybe throw the current trip average up there too.

Another vote for average on the gauge display.
I'd like to be able to reset the Today segment. There are times when I have a couple stops on the way home and I'd like to see the total trip, without the morning's numbers mixed in.

Data logging and Prius-specifics like SOC and battery draw/charge. That's all I've wanted. Things like precision to 0.01 for gallons used are nice, but the other two first.

The ability to correctly calculate fuel consumed by a lean burn engine would be great. Not having this makes all the mpg-related features useless on a MT Insight. Probably not a high priority, though. Are there any cars with lean burn capability currently on the market?

Part of the problem may be what Honda reports through the ECU.

With the Query/Response configurable gauges it my be possible to "ask the right question" of the ECU to determine if it's in lean burn. Then we would just need to sit down with Ron and figure out how to program up a custom gauge that takes the mixture into account.

For what it's worth, the Prius has the same problem. Right now SGII calculates fuel consumption using two variables, RPM and engine size. On the Prius when the RPM drops below 1000, the injectors cut out. You can get the car to do this at 60 mph if you have strong 6 bar SoC. Problem is that SGII doesn't account for the fuel-cut.

Might have a same query response answer.

boolean fuelCut = QUERY_RESPONSE();
uint rpm = RPM_GAUGE();
uint gph = GPH_GUAGE();
uint mph = MPH_GUAGE();

// Yes... 9999 is no good, but this would give you a fun iMPG guage to track fuelcut.

if(fuelCut) {return 9999;} else {return mph/gph;}

Now from talks with Ron, I didn't get the impression that the gauge programming would be that complex, something more like AND / OR / NOT. The solution would be to have fuelCut return 0x0000 or 0xFFFF, then to use that to AND with gph, but then you'd have to figure out how to handle div-by-zero.

Point is, if the right instructions are available to program the custom gauges, only one guy has to figure out how to do it, the post it on this thread... :D

Trip gauges can now be on your 4 gauge display (iMPG and aMPG next to each other)[/LIST]Yay! That one is on the top of my list.

See this post (http://www.cleanmpg.com/forums/showpost.php?p=40034) for my own thoughts on the custom-PID feature
as it appears to be being developed, and how with public
participation that could turn into a seriously useful monster.

Called Scangauge folks today to get a replacement SG. (they had a batch where the backlight doesn't work on some).

Was told they have a bug in the new Firmware but it may be ready in a week or so. Folks who buy within 30 days before it's release get a free upgrade to the new firmware if they pay the shipping to send it to the SG folks.

PS: got over 43mpg on my first tank in my 1998 Accord. 4cyl automatic transmission.

It would be even better if we could apply the upgrade ourselves via a download.
Did they specify which is the minimum firmware revision that would be eligible for an upgrade? I got two SG-II's versioned at 3.0.X, and it would be really nice to know if they are upgradeable at all.

Well, I got my SG loaded with the new firmware this evening. Sorry for the terrible quality pictures. The XGAUGE feature allows for a total of 25 user-defined gauges. You have to enter the mode and PID for the Tx field, and you have to enter the message filter, size and location of data. You can then multiply, divide, and subtract.

Unfortunately, Ron and I were unable to get my FEH's Traction Battery Control Module to respond, but I was able to program a few things this evening, including transaxle temp and HV battery voltage.

You can also display trip info in the gauge mode, so your tank or current or whatever MPG can be displayed without having to switch modes. Also, you can enter the price paid for gas and get a cost per mile displayed. I am going to keep playing with it whenever I get the chance.....

Hi Carl:

Quick call to owners... Post the PID support on your vehicle. Look at my
Prius thread to see how to get the mappings.
Then post a new thread to the ScanGauge Forum with the PID support list.

Just a quick update..

I have found some bugs in the new firmware, most of which Ron was already aware of when I mentioned them to him. I am going to run some more stuff this weekend in hopes of verifying some things that Ron wasn't already aware of. I am supposed to get another firmware rev loaded into my SG on Monday, at which point I should have access to all of the battery info. Ron has verified that he can now communicate with specific modules.

The ability to display trip stuff on the gauge display is certainly a great feature of the new firmware. The cost per mile/trip/day/tank is a real eye-opener, too. Maybe some legislation to mandate the cost display into the instrument cluster, and blue tooth the price from the pump into the vehicle....nah, too Orwellian.

Carl,
Please pass along the PID support lists I'm trying to advocate on this forum. I'd like to eventually see all SG users publish a PID support list for their vehicle. Should give Ron and Co. a good head start on that XGAUGE database.

What processor does the sgii run on?
.

Might have to get a screwdriver and figure that one out. Don't know, but I know the FW footprint is only at less than half of it's capacity.

Lots of room to grow on.

The SG uses a Microchip controller. Apparently, the original was discontinued and the replacement is not 100% compatible. I think this is where a lot of the firmware glitches are coming from. I didn't get the latest update today, but maybe tomorrow....

Another update...

I went to lunch with Ron today and got the latest firmware upgrade for the SG. I can now display SoC, Battery temp, charge/discharge limits, etc. HP and Torque for the ICE is also display-able, which is pretty interesting. Wish my '71 Mach1 429SCJ had an OBD-II port.....

I will take some pictures of the new display this evening. For non-FEH people, there is still some detective work to be done as far as message IDs, etc. I will try to convince my neighbor with an '05 Prius to let me connect up to his car......

Very cool. Is this available to everyone, and if not is there an ETA. Any idea how much the upg will cost? Also, any news on the upcoming data logger?

Very cool. Is this available to everyone, and if not is there an ETA. Any idea how much the upg will cost? Also, any news on the upcoming data logger?Reports are that data-logger is bumped until after this release. I'll defer to Carl for the release schedule, if it's even known at this point

Wow, that was fast, thanks, so the FW release is imminent?

Should be available now, but officially I guess maybe in a week or so. Watch the website for details. It does work with Prius enhanced PIDs, too! I have coded up a lot of the FEH PIDs, should be available on the web site along with all the others.

I posted a list of VID's that are listed as "supported" when decoding the support bitmask.

Again... Thanks a ton for helping hammer this out with Ron and bringing it to the masses.

Supposedly, all ScanGauges are now shipping with the new firmware that includes the xgauge feature. I have a copy of the manual that comes with it, and it's pretty sparse right now. If anyone needs help on putting in xgauges for the FEH, I'll gladly help. As for the Prius, I know that there are a couple of hundred PIDs that can be retrieved, including SOC. Many are mode $21, some are mode $22. I meant to get a list so I could try it on a friend's '04 Prius, but I'll have to call back tomorrow.

Also, a minor change has rubber buttons instead of the hard plastic ones.

I didn't help that much, to be honest. Most of the bugs I found during beta testing they were already aware of. The one thing I did help on was the ID for the FEH traction battery computer, which resulted in Ron adding a message ID field in the transmit part of the xgauge. This also helped because the Prius stuff is on several different computers with different ID's.

Anyone who recently bought a SC can send it to them to have the new firmware upgrade installed, or if you live in the Phoenix area just stop by!

Heard rumors that there might be a FW update procedure posted on the web this week.

Keep your eyes peeled.

Here's what we have so far (look for XGAUGE):

Thread about the subject

You can now order firmware updates to your Scangauge.

http://www.scangauge.com/support/upgrade.shtml

According to the website:

Free Upgrade if your ScanGauge was purchased on or after July 20th, 2007
The cost to upgrade if yours was purchased before July 20th is $25 (USD) per ScanGauge

hopefully I didn't gloss right over it, but are Honda specific PIDs (non-hybrid) available with the firmware upgrade?

Thanks!

Honda owners need a champion to slueth the PIDs to see if any are available and if so what their scaling is. I've never owned a Honda but I know Toyota doesn't follow the rules too well with regards to enhanced diagnostic data from the OBD-II port. At the very least you can send a mode 01h 00h PID to find out which of the legislated PIDs are suported. Beyond that, you need to find out if any vehicle-specific diagnostic modes are supported, and which mode and did they follow the SAE format.

CarlD, how can I go about researching the Honda PIDs (or how did you all crack the Toyota nut)?

Any progress on Honda PID's?
Thanks,
CP

CarlD, how can I go about researching the Honda PIDs (or how did you all crack the Toyota nut)?


I had virtually nothing to do with cracking the Toyota nut, except for the fact that the FEH battery computer address was 0x0745, which I think led Ron to investigate non 0x07E0 addresses for the Prius. I think Ron either has a Prius or has complete access to one so he could hook up his CAN tool to it and see the bus traffic. Toyota didn't always follow the J2190 format (Ford did), which made things more difficult.

For Honda, the place to start would be a factory service manual to see if there is any mention of PIDs. The best scenario would be to get your hands on a Honda factory diagnostic tool and monitor the bus traffic when reading things like SoC, etc. It is somewhat ominous that there is no Honda in the obd-2.com list of enhanced data, though. Also, I don't know if there is a Honda hybrid driver in the Phoenix area willing to drop by Linear Logic to let things be tested out if and when needed.

My house is just a stone's throw from LL, so stopping by in the evening to test out things on the FEH was really easy.

Carl, please see this thread here (http://www.cleanmpg.com/forums/showthread.php?t=8041):

As I had mentioned to Ron, I am willing to offer any assistance possible. Just let me know and I'll see what I can do with my resources. Sadly, I am not close to you at all but I may be able to retrieve certain details and data that who knows, may help?

The basic service literature for the HCH-2 does not contain any references to the supported PID list or CAN addresses. I do have access to additional literature and materials that may be of use.
