Thanks Finn. I downloaded the files and notes. Once you are confident the hardware and software works properly we might consider a onetime production run of EC3’s for existing EC2/3 owners. I would like to have a tested spare available. It would likely take Tracy’s involvement to facilitate the board build or at least provided the suppler information and proper Rev number.

 

I really appreciate the work you, Steve Izett and Steve B. are doing.

Subject: [FlyRotary] EC3 software for Renesis RX-8/LS2 coils fixed and uploaded

 

Here it is:
https://drive.google.com/drive/folders/1mVzPOxUwcGUlPizxnRF40nUyKBzfT4DC?usp=sharing
It's EC3closedloop.zip.

You may want to grab it now in case Google decides to close my account :)

You can program the 18F452 chips directly using the EC3CL8.HEX file, or open EC3ClosedLoop.mcp in MPLAB IDE, compile and program. This is for RX-8 (EC3 engine type A8), LS2 coils (D585), large secondary injectors, default is wide band O2 sensor.

Turns out Tracy has never programmed or delivered an EC3 for Renesis with LS2 coils.
Software was missing code to load LS2 coils dwell time.

I added Steve's code for configuration bits so don't have to remember what to set them to when programming.
I set all protection bits to zero to avoid any chip reprogramming troubles, but you could change to:

; CONFIG6L

  CONFIG  WRT0 = ON             ; Write Protection bit (Block 0 (000200-001FFFh) write protected)
