As you all know I've been tinkering with IMA control over the years and the BCM gauge was a product I sold a few years ago. Well it all seems to be working pretty well as a combo over the last few few years. I've sold about a dozen to eu owners who have been very satisfied with it.
Now with Mike's agreement (18/6/2013) I have decided to release the device for worldwide sale.
There will not be an assembled pcb option at this time. It took me about an hour to build one so it's not very difficult. You need a fine tip soldering iron and good eyesight though as the parts are quite small. The code is provided in hex form and requires use of the simple pic programmer as used in my other projects. The source code is also available in this thread.
The IMA control integrates with the throttle, brake, clutch signals, for input at present. It also interrogates the BCM data and uses the 5 way joybutton for user control/operation. The pcb also has inputs for the vss and map sensors but these are not used by the present code.
My present code has the core gauge functions, ima battery volts, temp, soc, amps and control over the IMA assist/regen. It has a sport/rally mode where when throttle depressed more than 90% gives full assist.
It has the 5 way joybutton cruise type modes.
Assist/Regen are controlled by the 5 way button.
It gives 40 levels/units of adjustment for assist or regen with my system.
Up = Inc Assist or Dec regen by one unit
Down = Dec Assist or Inc regen by one unit
Left = Dec Assist or Inc regen by ten units
Right = Inc Assist or Dec regen by ten units
Centre = cancel and menu mode if held down.
All the levels are held until cancelled so you don't have to have you hand on the joybutton once you have activated it.
Pressing the centre button, Brake, Clutch or engaging sport cancels previous settings.
So for instance when driving on the flat at 40mph one click right (10 units) gives me about 12A of assist which is held until i cancel it. If I then put my foot down sport mode engages, and you get whatever current the system can deliver at that rpm/soc/temp etc. When you ease your foot back off the throttle system reverts to standby/oem mode or your previous setting.
