OBDIIC&C What will/does it do?

Well it plugs into the OBDII port like a scan/ultra gauge and

1) Reads and display ENGINE data, load, water & air temp, O2 sensor voltage etc
2) Indicates Lean Burn mode via green led
3) Reads and display IMA data bat temp, amps, voltage, soc etc etc
4) Reads, shows and clears IMA and ECM codes
5) Allows manual control of BATTERY fans and SOC level.
6) Has an audible water temp alarm

Is it better than the scan/ultraguage type devices?
Well that's for others to say, but it can access and display a lot of data they can't, including IMA specific information. It can also log/export data to a connected laptop directly into an excel spreadsheet.

The current version of the software and owners manual are below.

Please review any of these you are unfamiliar with and add data to the spreadsheets as relevant.
The more data we accumulate the better our understanding of the cars will become. :)

I have OBDIIC&C stock ready for dispatch. :)

I have built and tested units including 3d printed case. $350 inc postage and paypal fees.
I have a plentiful stock of plain pcb's. $49 inc postage and paypal fee.

All include lifetime software license. Hardware is rtb 3 year warranty.

All ready to go.

Thanks Peter

I'll take three. ;)

How about that gizmo you posted about a while back? I studied it a bit. It seems to be a really nice piece of kit, as you would say.

Geoff's Projects - The Maximite

Perhaps a little expensive/overkill for these purposes though.

What does the C&C part stand for? Command and Conquer? :D

Data logging will be my main focus/want. Ideally, it would be nice to log every data point the car spits out!

One suggestion regarding DTCs:

Is there a way to get the blink code too? That's one of the great things about the HIM, it pulls the full code, ie: P1449-78, without having to try and read the dash blink codes. :)

Possibly like the BCM gauge it will evolve/improve over time as I make more discoveries about the data stream.

The Maximite looks a nice device but I'm getting quite familiar with the basic pics now and like a minimal hardware approach, no point in having another huge learning curve to get up to speed with that. Feel free to get one and program your own gizmo!

I like using the small pics as that forces me to refine the software to pack more into the code space, good mental exercise.

This may seem like a really stupid question but why not use dash command and an automotive PC. The "hybrid battery pack remaining charge" is a supported output along with the DTC's for an ODBII compliant ECU.

By removing the dash, laser scanning the surround and rapid prototyping a replacement, a TFT widescreen could be mounted in place of the LED dash and the sport button on the steering wheel used to scroll through a variety of screens.

You could then tooth the data to your android or iphone app and even get a real time graph of you MPG on screen...

or is this a really stupid idea?

There is so much more information available from the OBDII port that is Insight-specific, no aftermarket gauge is going to be able to compare to a purpose built job.

We might be able to make some XGauges for the Scangauge, but I don't think it will ever be able to grab all of the IMA data.

OBDII devices are a dime a dozen. Really, the whole point of this is to get IMA data. Anything else is just icing on the cake, as far as I'm concerned..

Mike you will be wasting your money if you want the IMA,SRS,ABS data and/or some of the Insight specific OBDII data. If you just want the generic OBDII data fine.

The Scangauge has the wrong connections and protocols to grab anything from the IMA side. It's a generic OBDII device with a few bells and whistles like the thing in your link, XGauge will not work for anything that is not sent/recd over the K/Line that sadly means detailed IMA,SRS,ABS stuff is not available to it.

I have now captured samples of data from every IMA,SRS,ABS command and am about 50% of the way through the Insight specific PGMFI ECU OBDII ones. There will now be a looonnnggggg pause as I study the data and work out what it all means and how to emulate it all. I have worked out the IMA CRC routine and now need to work on the software/hardware. Keep watching these threads for updates. For those with the BCM Gauge it may be possible for those who can weild a soldering iron to adapt it to do the basics.

Excellent Peter. Does that mean you got your new HIM working?

Does displaying a specific parameter in the HDS make it only request that data?

OBDIIC&C Gauge Pic 16F1825 Variant

Dear Members

Here is a proposed schematic for the production OBDIIC&C V1.00 pcb using a 14 pin Pic 16F1825
This has 4 times the memory and ram of the 12F683 I used in the BCM Gauge and runs at upto 32mhz on the internal oscilator instead of the 8mhz of the 12F683. So we have a lot more room for functions and data etc.

www.solarvan.co.uk/obdii/ODBIIGauge16F1825.jpg

I'll probably develop the basic software on the 12F683 as that forces me to be more careful about program size, then just port it over to the 16F1825 when I get some pcbs in stock.

If people are interested in a pcb put your name down on a list on this thread and post it here like on the MIMA thread. Just add your name to the growing list. I won't be supplying any other parts apart from the pcb or any ready built pcb's. There will be a parts list spreadsheet and you buy the bits and assemble it yourself. I don't have time to build the units. It will be a requirement to have the/a pic programmer as I will supply the hex files to download via the web. If someone wants to offer a build your pcb service for a fee then great. Please step up to the line.

I won't be ordering any pcb's unless I get at least 25 people on the list. :)

Cost of the Pcb $55. That might sound a lot but includes postage and a profit margin to cover the cost of funding my further research into the Insight. I'll need a US distributor for American buyers who can send out the pcb's if anyone wants to volunteer? PM me.

I estimate cost of the other parts inc the 16x2 serial lcd would be ~$45 so the whole thing can be bought/built for $100.

I am dividing the software up into four sections at present. When it starts you get a menu choice.

1) OBDII Mode. Can display 4 parameters on the screen at once from the general OBDII list. At present I have it displaying Water temp, Air intake temp, Engine Load, Lean Burn O2 Sensor. This is hardcoded at present, but you will be able to choose parameters later. This mode also allows display/clearing of ECU DTC codes.

2) IMA Mode. Will display 4 IMA parameters on screen as above from the IMA list. It will also display and clear IMA DTC codes. It will allow manual control of the battery & MDM fans and setting of the SOC level for those with grid chargers. Also allows setting of SCS mode for flashing dashboard light diagnostics.

3) ABS Mode. Will display 4 ABS parameters on screen as above from the ABS list.

4) SRS Mode. Ditto as above and will allow display/clearing of SRC DTC codes.

5) Config Mode to allow unit selection for display/logging etc etc.

Clearly there is a lot of work ahead, the hardware is the relatively easy bit, the software will be the challenge, but functions will be added on a regular basis as I decode the secrets of the data.

Comments?

Count me in for a (pre-built if possible) PCB!

I like your choice of standard OBDII parameters — would it be possible to mix those with the IMA parameters? It would be nice to monitor voltage, current, and engine load for a complete picture of power delivery. (Nice but not necessary…)

I've read about the HDS software having a locked section. We have the general repair version, but under body electrical, there's a few more modules. The dash responds under body electrical. That allows you to calibrate the speedometer and set/reset odometer. There's also a section in there for the immobilizer data so we can program new keys to the car. I've only found small incomplete data on that stuff, so it may be the HIM that doesn't allow us to do those. I've read a little saying it's the HDS software that requires a certain dealer number to work correctly. They also said the immobilizer section requires a connection with the Honda mother ship.

I'm sure we will eventually sort most of this stuff :) I have been looking at it.

Sorry Right Lane Cruiser there is no built pcb option from me.

All the other stuff you mention should be possible as we progress over the next year or so. Please be patient though.

I'd be down for a prebuilt one. I'm not confident in my building skills. *Cough* Eli, I'm looking at you for our stateside brothers.
