Subject: How to make a program change to my EC3?

I have an EC3 installed in my O-200 powered Quickie Q-200. I was wondering if anyone might have any suggestions.  I need a simple (famous last words) programming change and was wondering if anyone might have any idea how I might do this.

The problem is, the spark is not retarded during starting and all too often I get a nasty kickback. Doesn't happen all the time, but it still occurs.  I have figured out that first running the starter without the ignition turned on seems to "loosen up" the engine and I have a better chance. This kickback has resulted in damage to the starter bearing and I have returned it to B&C for repairs.

The circuit hoard has two main chips which are removable. The "A" side is the main controller for normal operations and the "B" side is the redundant side. 

Is there any someone could figure out what programming language was used, then modify it a bit?

Tracy programmed Lyn French's controller to retard the spark during starting, so I know it can be done.

If I can't make this programming change, I'll have to spend $3,000 - 5,000, installing another system, such as SDS, so I'm making a last ditch attempt.  I would appreciate your thoughts.

Thanks.

Sam
