We're working on some firmware changes that allow VEMS v3.x => round data transfer.
Actually, maybe a separate (that has no wbo2 controller inside) round firmware that polls v3.x and displays lambda and EGT.
- Is it OK if it uses up the RS232 port ?
- That is, while you're tweaking v3.x with megatune, the round is unhooked (and does not show real values).
Other functions
Besides the obvious display functions, some other useful functions could be used:
- button (LCD page-change?)
- 2 power outputs with flyback (60V FETs), max 5A (2..3A max recommended)
- external gnd referenced analog output
- RPM (wheelspeed), and maybe other data from round => v3.x
