I didn't ask how many. The hot question really is how big is the demand (quantity)? I probably have enough data from him (schematics, parts lists, PCB layout) = to get a production run done. Tracy is serious about having retired. I was really, really lucky to get hi= s help. I think a big reason for his decision to retire is to have time to enjoy li= fe. I think the majority of his time before his retirement was spent on sup= port (phone, emails). He really has no economic incentive to come out of retirement. So while we could get a production run done, I doubt anyone would be willin= g to spend time on support -- certainly not for new installations. Also the= variety of engines, accessories and specialized programming for some insta= llations would make it a nightmare to program the chips. Solution for that = would probably be to read the working chips for your installation and then = program the new chips with that, but then some would not get the latest fea= tures (closed loop, auto program using EC3 w/o EM). I thought I might take it on, but having second thoughts :) Will probably be a few days before I'm ready to roll the fuselage out of th= e hangar and do engine runs.

= Hi Bobby,

Actually Tracy does have a few new EC3 boards. I didn't as= k how many.

The hot question really is how big is the demand (quanti= ty)?

I probably have enough data from him (schematics, parts lists, = PCB layout) to get a production run done.

Tracy is serious about hav= ing retired. I was really, really lucky to get his help.

I think a b= ig reason for his decision to retire is to have time to enjoy life. I think= the majority of his time before his retirement was spent on support (phone= , emails).

He really has no economic incentive to come out of retire= ment.

So while we could get a production run done, I doubt anyone wo= uld be willing to spend time on support -- certainly not for new installati= ons. Also the variety of engines, accessories and specialized programming f= or some installations would make it a nightmare to program the chips. Solut= ion for that would probably be to read the working chips for your installat= ion and then program the new chips with that, but then some would not get t= he latest features (closed loop, auto program using EC3 w/o EM).

I t= hought I might take it on, but having second thoughts :)

Will probab= ly be a few days before I'm ready to roll the fuselage out of the hangar an= d do engine runs.

Thanks Finn. I download= ed the files and notes. Once you are confident the hardware and software wo= rks properly we might consider a onetime production run of EC3=E2=80=99s fo= r existing EC2/3 owners. I would like to have a tested spare available. It = would likely take Tracy=E2=80=99s 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 Ste= ve B. are doing.

Here it is:
= https://drive.google.com/drive/folders/1mVzPOxUwcGUlPizxnRF40nUyKBzfT4DC?us= p=3Dsharing
It's EC3closedloop.zip.

You may want to grab it n= ow 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 Renes= is with LS2 coils.
Software was missing code to load LS2 coils dwell tim= e.

I added Steve's code for configuration bits so don't have to reme= mber 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&n=
bsp; WRT0 =3D ON          =
;   ; Write Protection bit (Block 0 (000200-001FFFh) write protec=
