There exists configuration (aim channel and Ax+B linear transformation) for 4 top (T0,T1,T2,T3), and 4 bottom values (B0,B1,B2,B3).
8 display modes (disp_state variable)
- 0..3: T0/B0 T1/B1 T2/B2 T3/B3 (displaying "pairs")
- 4: display peak value of T0 and B0: PT0/PB0
- 5..7: T1/B0 T2/B0 T3/B0 (displaying B0 with Tx)
As you see, one bottom configuration (B0) can be displayed with any of the 4 TOP configurations.
The AIM mode for the TOP and Bottom display can be enabled individually (with segment0=A5 and segment3=A5 respectively). If only the bottom is in AIM mode, and the top display not in AIM mode, eg. segment0=00, than normal value is displayed (lambda / AFR in this case, measured by round itself).
to get Lambda, EGT, RPM, MAP and other signals via serial port from the V3.3 ecu
Round (firmware since 2008-08) can now receive AIM (protocol 19200,8n1 rs232, standard aim protocol, 5bytes per packet) from PC or v3.x
- the genboard (firmware) side is under testing. It requires genboard to send in 19200 baud (likely megatune will use the same baudrate)
- Any channel defined in the AIM protocol can be displayed on top or bottom display, with any scaling, offset and dot position
- button can be used to switch display state (mode): 7 sets of top/bottom values can be configured
- the 8th mode is the peak value remembered for top/0 bottom/0 (peak value resets at powerup). Useful for MAP, RPM or any other channel.
- any number of rounds can get the data (eg. 1 genboard feeding 9 rounds displaying total 18 data).
Feedback from round => genboard (useful button for launch or table-config-switch?) is not planned in 2008.
