Re: Proteus - Waterproof, High-feature ECU!

we have small talk about EGT here: https://rusefi.com/forum/viewtopic.php?p=44020#p44020

but... YES ..
two EGT channels will be useful on proteus

To Hmelik:
you need 2 wires for SPI bus .. SCLK and SO
..and one wire / line for CS# for each chip ..

Re: microRusEFI

So .... 12VRelay is DOWN, when the starter is ON .. Right ....? (12V_MREL line) If the answer is YES, the E-THROTTLE is OFF, and we have no power during start / cranking - for it THEN we can't flush cyls (if we need) we can't add more air (via throttle pedal) we can't driving idle ..etc ..?
