I have taken the old open source source code from MegasquirtAVR and made it work on my Arduino Uno. I remved all keyboard, lcd and button code as the pic count is very limited. Bench tests are fine and all is well, next step is to get it running in my car.

One thing I would like to do is have a 16x16 ve table instead of 8x8 as it is currently. The protocol is all done for this but I'm having trouble setting up MegaTunix for the new table.

Any pointers to adding a few new interrogator commands? Its MS1 compatible at the moment and I just want to add new commands to get and set the 16x16 table.

Seems MegaTunix documentation is very limited.
Any help would be appreciated
