5 and 6 cyl on main connector trick #96

Closed rusefillc closed 1 year ago

rusefillc commented 1 year ago

https://github.com/rusefi/alphax-4chan/issues/90 would allow 6 cylinder using aux connector

we need through hole vias on aux 2x ignition traces to allow jumper wires
(no action needed) let's make sure to keep at least some jumpers on less important pins like D4 FLEX knock opposite of https://github.com/rusefi/alphax-4chan/issues/76

This would allow 6 cylinder on main connectors with board mod.

injectors 5 and 6 could be made from existing low sides by just removing diode

Which existing GPIO could be used for injection? if it could be any, like IDLE/IDLE2/NOS/VVT/VVT2, then I agree with what you said. My mind is on doing a 6x6 ETB engine with no VVT so losing VVT control loses me nothing

IGN5-6 vias for ignition IGN7-8 for VVT1-2 or INJ5-6 (need to remove D53, D54)

Can this be done on older boards?

probably no access to those MCU pads
