Hi Alexei,

We believe so too :-)
In the meantime there were lowpass-filtered differential input amplifiers
(going to ADC channels, usable as more EGT channels, for example)
and onboard flash added (eg. for logging).

It's available from the development page:

latest genboardv30....
The zip contains the eagle files.

have fun,

I guess I should direct the diy-efi to a different folder than the noisy
megasquirt
list, this mail almost sneaked unnoticed.
