Fair point. I dunno why I didn't recognize the connectors, I used 4 pin mini50s on a project a couple years ago.

Re: CAN bus to CCD bus Protocol Translator(Chrysler PCM Simulator)

I did manage to reduce the size somewhat. Now I need to get a lot of sleep and do more rounds of checks before sending it off for manufacturing. The SD card slot was rotated 180 the wrong way and I almost did not notice.

Re: CAN bus to CCD bus Protocol Translator(Chrysler PCM Simulator)

Hi Alexia,

Nice work.

Im trying similar work on my 97 ZJ V8 with a Protune ECU.

Can you share some schematics and code?

Regards from Brazil

Re: CAN bus to CCD bus Protocol Translator(Chrysler PCM Simulator)

The fabrication company just sent me a picture of board number one! There are two issues with the solder mask that do not affect the board functionality that I will have to correct for production boards. Once they arrive I will make any repairs and assemble the through hole parts.

Re: CAN bus to CCD bus Protocol Translator(Chrysler PCM Simulator)

They are here and I took a few minutes to solder on the through hole parts to board #1! I will be bringing these boards online over the next few weeks.

Re: CAN bus to CCD bus Protocol Translator(Chrysler PCM Simulator)

Alexia - did you also come up with an enclosure for this? I'm doing an ls swap into a 99 XJ and was going to build my own, but if yours is reasonably priced and has a good enclosure I'd rather just buy it. I've done lots of work on CAN avr's but never touched their SAM stuff. Seems like the feature creep got to you here :p. Are you also doing a CAN bootloader or will it be USB only?

I do have a steel enclosure I designed for this that will eventually be modified for the production boards. For this small batch of five development boards I am going to just 3D print some enclosures. As you said, there is too much feature creep, so I have already designed a new PCB that is 33% smaller due to better component layout and removal of the SD card slot.

The production board is not final. I mainly removed the SD card slot for now due to the overall design cost of having a SD card included; reliability, its intended usage, and the fact that any functionality I intended to build with it would mostly be replicated by just having it exist as part of mobile application.

Do you mean being able to flash the board over CAN? At the moment it is JTAG only for flashing. Until a production board is ready these are very much "You need to know what you're doing" devices.

I am not trying to bind myself to a date, but I would love to get the final product out in time for this year's SEMA show. I have a big vision for how the whole system works and I am doing it all by myself without any funding.

Re: CAN bus to CCD bus Protocol Translator(Chrysler PCM Simulator)

Flashing over CAN isn't really needed, but you've got a lot of stuff going on with this board. When the unit is mounted it could be hard to get to, and since it will be integrated with the CAN bus of choice (GM, Haltech, etc) it should be available at the DLC. It's not a big deal, just a nice to have since someone else is doing all the work. It would be nice to just have something compact to make the overhead and gauge cluster go without all the other i/o, though.

I am considering "slim" models later with just the most popular interfaces.

The GPIO is for items such as air conditioning request and analog output for older transmission controllers that need a TPS signal.(Or even just an analog gauge.) I have a lot of experimenting and coding to do!

Re: CAN bus to CCD bus Protocol Translator(Chrysler PCM Simulator)

It would be helpful for Gen 4 GM swaps to have those inputs, as well as cruise controls. Most of those ecms get that info over the high speed CAN from the BCM nowadays. These would be standard across pretty much all gm platforms, so you should do it

How are we doing with this? Should we get a GoFundMe account going?

Hi Alexia! Im too late to see your topic but I think some simmilar translation to replace entire ECU from my 2000 XJ eith a fueltech and drive the AW4 transmission! As your versuon in haltech, I want tu preserve the cluster and drive by fueltech!

I see your github is not available anymore, maybe you done your product or can help me to translate to CCD bus the CAN stream from Fueltech? (I can help eith this!)
