Bobby,

If you haven’t already, consider reversing the chips on the board and then copying A (originally B) to B (originally A).  This might restore all programmable parameters to the malfunctioning chip.  I don’t know if that would be a risk for corrupting the good chip but that seems unlikely.  I’ve done this to enable reading parameters from the originally B chip.

Thanks Finn. We will  explore this as a possible solution. Also the duplication service.

 

Another question. How to tell if the controller is truly corrupt? When Dennis started the engine in Mode 4 he hit the store button 2-3 times for priming. I’m wondering if Mode 4 has another function when the engine is not running?

I think I paid less than $20 for my PICKKIT3 (clone, I guess).
You may get away with programming it in-circuit (you'll have to power the EC2 board) if the board has the 5 or 6 header pins.

I put an PLCC68 socket on a piece of prototyping PCB with 6 pins for the PICKIT3 connector.
All ground and supply pins have to be connected.

We think Dennis H. has a corrupt A controller chip. He inadvertently started the engine in Mode 4 and things went bad. The B controller is running normally so we have a good chip to work with. This is one of the early big box EC2’s. Dennis and I worked a few hours trying to tune the A controller. We reset Modes 1,3,4,6,8.multiple times.  Mode 2 is to copy A to B and I don’t think Mode 5 and 7 are used according to the book. There may be an issues with the Programming Head. Sometimes we did managed to keep the engine running with the manual mixture control. We noticed changes to the engine while cycling through the program modes. On one attempt we managed to get Mode 3 adjusted at 19” MP. We were then able to make adjustments in Mode 1 up until about 24” MP and the engine just stopped. We restarted the engine and we could not keep it running or make any Mode 1 adjustment that helped. .

 

We pulled the EC2 and Program Head for inspection. The Mode switch is a little sticky so we will use mine to on the next attempt. So any advice were to get a reasonable priced compatible 64-pin QFN programmer? Dennis’s grandson will be the one copying the chip and said Microchip’s programmer was about $400.  We are looking for chips and may have located some at Microchip direct.
