Micro vs uaefi

[cpipkin6.5x55]

I am looking at doing an efi upgrade on my harley. What's the difference between the microrusefi and the uaefi?

proper connector and proper case are the advantages of microrusEFI

on a harley you would need dual channel WBO

what year harley/what motor?

So not CANbus, does this have Automatic Compression Release (ACR) valves?

[cpipkin6.5x55]

No canbus no compression release. It is a fairly simple efi system. Inputs on the bike are engine temp, intake airtemp, vss map and tps sensor . Output are fuel injector coils and fuel pump and cruse control. I have to add a wide band sensor or two.

and cruse control.

How does the cruise control work? Electronic throttle body?

[cpipkin6.5x55]

Cable operated cruise control module. Same modual works with the carb modules so I don't think ecm does anything other than pass vss to it

Just realized that this is a small mess

On the bright side we have https://www.shop.rusefi.com/shop/p/dual-channel-wbo
On the other side https://github.com/rusefi/uaefi/issues/45

* uaefi has one CAN-based WBO on board
* firmware does not support mixing CAN and analog
* external dual channel CAN would conflict with on-board?
* firmware can go use dual external analog which would be LAME

[cpipkin6.5x55]

So I could go uaefi with dual analog wbo2 or microrusefi with dual can bus wbo2modual?

Looks like that yes.
