Just to make sure my position is understood in relation to this thread, I am not defeating the proprietory security systems or software controls. The work I am doing is purely to interogate the IMA and other onboard systems to gather live technical data/dtcs for my IMA/Gauge control projects. Access to this data is enshrined in EU Law and not allowed to be the sole right of the dealers. i.e. You can get you car repaired where you want in the EU and they must all be able to reset codes or do diagnostics etc
Please add your names to this list if you want a bare pcb. Cost $55 inc P&P
Right Lane Cruiser x 1 (Prebuilt)
MadManMostafa x 1 (Prebuilt)
Eli x 5
I would be up for assembling the PCBs for people once I figure out how long it takes and the cost of parts.

I also agree that it would be nice to mix and match the displayed parameters. It would also be nice to get more than four. A lot more.
Will the device only be able to log the displayed parameters? I would like to be able to monitor and log say 10 parameters at once, and am willing to be patient for such features as this project evolves. Being able to log 10+ parameters while only 4 are displayed might be acceptable though?
It's very early in it's development - I almost wonder if we should allow a prototype design to be designed, built and used for a while before you settle on a mass production design?
I think a 20x4 LCD at minimum would be much more suitable for this device. $100 for a device this powerful is an absolute steal when something like the Scangauge is $160-180.... I'm not concerned about spending a little more on components.

Goods points Eli the lcd can be swapped at will already for a 20x4 device, but I'm also concious of those who have a 16x2 serial lcd from the BCM gauge.
Breadboard & software development is taking place using the 12F683 and a 16x2 lcd.
I have a 20x4 to hand ready for when I get to that stage. Expanding the stuff on screen for easier readability is simple when we move to the bigger pic, at the moment it's the processing the data which I'm concentrating on.
I'm going to start sending commands to the MCM today to see what happens.
I think i have the IMA BATTERY and MPI fan controls worked out
Logging of the parameters on display is very easy and logging more will come later, but anything we get over the bus can be squirted out of the serial to usb lead as now.
I assume Eli you would be up for being a prototype tester? With early access to the code
Edit
Here are two revised schematics.
1) Is the 12F683 version I'm using on the breadboard for code/hardware development. Eli if you want to build this you can assist. www.solarvan.co.uk/obdii/OBDIIGauge.jpg
It would kinda be nice to have even more than ten parameters to be honest. I think of this as an "All in one" device. Like an "Insight Gauge". If you pick four ECM parameters that the Scangauge can display plus the five BCM parameters that the BCM Gauge displays that's already 9, and off the top of my head it would be nice to see Knock Retard, Air/Fuel Ratio, ELM(total car amp draw), and probably others... I know this is probably all easier said than done...
Have you ever thought about using something like this? Please forgive me if this is ridiculous as I have no idea what is involved with implementing such a thing compared to the simple character LCDs, but you could do some pretty amazing things with it I bet.

I have looked at those but have not the time or inclination to do anything with one. Someone else can have a go.
I don't think the elm value is available from the ECM, as the sofware evolves things will get added, don't expect too much too soon.
As you add more parameters to your monitored list the refresh rate will fall accordingly.
eg with ten parameters we might be able to refresh at 1hz, with 20 at 2hz, and with 5 at 0.5hz etc etc.
It would kinda be nice to have even more than ten parameters to be honest.
I haven't seen any problems with my Insight and my DashDynoSPD keeping up with 16 parameters ... so the car side of it seems to be able to handle at least that many ... maybe more ( who knows )?
How much expense in time and money it would cost to implement 10 parameters instead of 5 ... or 15 instead of 10 etc ... might make it a deal breaker to go past a certain number... but for now this is still the early stages.
plus what Peter said about the more you monitor the slower the refresh rate makes sense too.

I agree ... Although there is still a lot of work to do ... I see a great potential in this device to surpass many of the limitations of other devices on the market... especially for us Insight users

Your dash dyno will only be talking to the standard OBDII side of the car though.
What refresh rate is it giving any way of telling?
Ironically we may be able to display mixed OBDII & IMA data quicker, as when the OBDII side is busy we can nip over to the IMA side and get some data on that bus and vice versa.
The ELM is in the PGM-FI screen. I guess it's called ELD.
The car/HDS can log up to 10 different parameters in "high speed" mode. I think that's where my basic ten number came from.
32MHz is a very fast processor. It shouldn't have any trouble keeping up with what the car can spit out. I think even the 8MHz pic should be able to, but then again I'm not a programmer. I'm having trouble understanding why for example in the case of the BCM Gauge the 8MHz pic takes 1.6 million clock cycles for each update if it's at 5Hz? Is that normal?
