Civic MIMA (civic and vs booster pack)

I'm sure its possible but a lot more work:
The IMA system in the Civic, while sharing many of the same functional modules as the Insight, do much of the control between modules with a high speed serial communication, similar to the Prius. The MIMA modification was made possible by the relitively simple hardware based PWM control that the Insight has between the ECM and the MCM modules.
If Honda released the codes and protocal information on the Civics internal serial control language, we could make a simpler and cheaper MIMA like control for the Civic...
I offered to develop a MIMA for the early civics but need someone with a car in the Uk to allow me to log data from their vehicle. Then they need to let me add my gizmo to test it.
And even for an Insight I think maybe instead of spending the $700 on a MIMA putting it toward a Lithium booster pack might be more cost effective.
The combination of a booster pack with the MIMA should work much better than either by itself.
It sounds like everyone with one of these hybrids should grid charge their pack:

What Mark meant was that it is likely your current battery can be refurbished with a Grid Charger trickle charger. We have many users here with otherwise severely degraded batteries who's cars are quite drivable with a weekly grid charge.
Another note on grid chargers: The batteries used in the cars are capable of a much longer lifespan than 5-10 years, but Honda's management of the battery is defective. A grid charger is something that you need to invest in regardless of which avenue you choose to keep your battery healthy for many, many years to come.
Your testing method for bad sticks is really ingenious but if you are going to repair other people's hybrids would it be a better idea to install a grid charger that can find bad sticks, send them home for a week or two and have them return with that information, remove the charger and repair the pack?:

The system can be expanded to a full pack tester that will not only allow charging, but safe smart discharging to allow automatic pack cycling and detection of the weak subpack sticks.
The Target price for the maintenance charger is $400-$500, and the overnight version for between $500-$600, but cannot firm up the price until I actually build them, and see what quantities your orders will support.
I will be providing two basic models, a 1A overnight charger that can fill an empty hybrid pack (6.5AH)in less than 8 hours, and a less expensive conditioner charger that will be limited to 350ma.
2.(Q) What is the difference between the Maint and overnight versions
(A) the Maint will only have a 350ma output, but the Overnight will have a 1.05 A output.
The maintenance charger will do the balancing job nicely, but it could take 8-25 hours to do the full balancing.
The overnight will do the same job in 5-8 hours.
It sounds like the ability to charge at faster than 350ma might be useful. With nightly grid charging and balancing you might be able to milk a few years out of a pretty marginal pack.
