MIMA for all Honda Hybrids

MIMA for all Honda Hybrids
a n example of what the new user interfac and display could look like

With the advent of cheap notebook/netbook computers, and the new hybrid cars use of CAN networks for communication between modules, the time may be ripe for the design of a new MIMA interface. This new interface will be CAN based, so the amount of hardware required to connect to the car system is simply to get on the CAN bus and do the MIMA interface through the bus.
I think that the Labview programming environment is best suited for the job, as it allows us to make an interactive display of all the important data in the car.
This photo is just a sampling of how the user interface could look. Many types of controls and displays are available as well as data logging, and full interface to all of the PC ports for I/O.
This system should be able to allow MIMA control for the hybrid Civic and Insight 2 vehicles as well as adding a much needed graphical user interface for the Insight 1 MIMA systems.

Connecting to the IMACAN bus

Making the final test connections
Nice group showed up on this frigid Saturday morning.
We made sure of the new CAN analyzer pin out, and rewired the interface to the car to match.
Jon was able to get the data into his notebook, so we should be good to go. He will develop a test procedure, and way to filter the datalog file, so we can better sort through the enormous pile of data we can generate in just a few minutes. We hope to start having some answers about what is passing over the bus this week.
Another nice gathering of hybrid enthusiast, if only it was 70 degrees instead of 20.

Jon came over and we covered some important ground.
Was great to meet him, he will bring a lot to the project.
The new power section and battery assembly lift out of a plastic pan that is one piece.
Like a big plastic bathtub. It looks like it could stay dry with about 10 inches of water out side it. All the wires come out from under a nice fitting and gasketed stamped steel cover.

The warning label no longer says "you will be killed ", it says you could be killed.

The BCM functions are now in the MCM, which has a dedicated "IMACAN" and a carwide shared "F-CAN" (Fast can)both networks are operating at 500Kbps .

Jon is working on decyphering CanKing hardare and software, Hopefully for dataloging and time stamping.
I will look at getting a datalog of the the MAP, TPS, and Battery current with the same time stamp, and we can see if a pattern emerges.
We would have liked to disassemble the thing further, but we had to go inside several times to get our body heat replenished by storing radiation from my carbon spewing but highly efficient coal stove.
