[help needed] rusEFU Huge Pinout Question

[ericoswald11]

Hello,

I am working on using a rusEFI HUGE ECU. I am working on using a GM LF3 with eWastegates so the pinout is needed for this project, the 4 H-Bridges and on-board lambda controllers. While going over the pinout I have a few questions about details for the pins.

1) In the pinout I see the on-board MAP sensor, can this be configured as the Baro sesnor?

2) I see 9 Aux Inputs. What are those rated for? 0-5V? 0-3.3V? any pull/down resistors?>

3) On gitHub it claims 2x temp sensors but I see in the pinout there are 4x? (27A, 28A, 29A, 30A) are these labeled correctly?

4) On gitHub it claims 3x VR sesnors, but in the pinout there are locations for 4? is pin 7B and 13B able to use VR or are they misableded?

5) On gitHub there are no mention on Digital Inputs but it looks like the pinout calls for them in a "switch" Looks like there are 4 of them (5A, 6A, 14A, 22A). Are they 0-3.3V, 0-5V or 0-12V inputs? What is the threshold voltage for this pin?

6) Pin A21 is labeled "Flex" but has a "hall" type? are there any more deails on this pin? is that a Digital Input?

7) On gitHub it claims 4x Hall Effect sesnors but there are 5x on the pinout (9A, 13A, 15A, 23A, 24A)

8) Digital Out (5C, 6C, 7C, 8C, 9C, 25C, 34C, 16D, 23D) what is the max amperage and voltage allowed?

9) Digital Out assigned pins (8D. 9D, 10D, 11D, 12D, 14D, 20D, 21D, 22D) are all assigned a function. do they need to stat that function or can be allocated to another function. also same as above? Voltage and amperage limits?


I understand this is asking a lot and I would like to help with documtation once I get all the information. Little background about myself I am a Calibration Engineer for an OEM and know a decent amout around ECUs, wiring, Engine Code and Engine Calibration. I hope to help out to this project as much as I can.

You are asking reasonable questions but unfortunately https://github.com/rusefi/rusefi_documentation/raw/master/Hardware/Hellen/alphax_8ch-c-schematic.pdf is the only answer for all of these.

Description could have typos, trust the pinout. Just try things.

Actually I desperately need help building base tune(s) for Harley(s), let me PM you
