Jaguar Repository on GitHub.com

[DeuceEFI]

Would you please commit your PCB modules file(*.mod), so that I can share some of your footprints. Thanks

I have just committed/pushed Jaguar.mod and Jaguar.mdc to my github repository

[DeuceEFI]

checkout the "experiment" branch, not master

Cool will do right now

I will take a look at HotCat's experiment schematics in the morning after sleep and coffee, in that order

[DeuceEFI]

Updated my repository with changes from lumpensack2003 for the grounds and the resistor between Vbus and 5v-USB. Also added the recommended Schottky diodes between the input 12v and the regulators.

I have locked the Jaguar PCB at Revision A.2 since I am pleased with the layout and will etch at test PCB in the morning.

I have committed/pushed my latest changes to the PCB (no changes have been made to the schematic) to show that the design is locked for testing. This commit has a Hash of 2fb502a51d6ea1f66a5c382bb9613fcd10f7623b dated 02/07/2012 at 0114 EST.

After etching the A.2 board today I noticed something... When I started drilling the holes, the pads started to get very small... It is do-able for testing the USB communications to the CPU, so I will continue drilling holes and use it for bench testing, but I have committed changes to my repository showing the larger pads and even some text.

I will etch and drill one of these before contacting Silver Circuits to have a pilot batch of 4 made professionally so that I have the ground plane on the Thru Hole side.

If you see any issues, please let me know, I would like to order the pilot batch either on Friday 2/10 or on Monday 2/13.

Thanks,

Updated repository with new optocoupler design, so new PDFs to review

Ok, here is on look at idle and one at 3400 RPM, When I revved the engine, the EST tracked the TACH signal (with the advance added of course).

Green trace is TACH signal, Blue trace is EST signal.

They are also in my repository in the docs directory.

OK, I finally understand these! :-)

I will play with the code now and see if I can do something useful for you.

As of freeems-vanilla git hash 9d17091153785233cc6bf310b1b5330d00c5cc21 the Deuce Coupe is able to start and have ignition advance controlled by FreeEMS on my Jaguar A3 Serial #1 board.

I am now working on tuning the engine and having fun driving it out of the garage and around the driveway.

Post some videos! :-)
