Then when you initially start, the firing point should occur=20 after TDC by a couple degrees reducing the kick back probability and=20 once running you can adjust the timing advance once for you normal=20 operation and be done with it.. The main point is setting the static timing point so that it occurs af=20 few degrees after TDC on the pulley. Its been a while for me, so the rest of you guys jump in here. Sam=20 shouldn't have to swap out his EC3 to fix his kickback problem.

Hi Sam,

Bill makes an excellent suggestion. = =C2=A0When setting up your static timing pointer to your pulley, if you mo= ve the spot for TDC on the pulley so that it is a few degrees before/after= (rotation wise) =C2=A0the timing pointer (A little help here, can't recall= which way is before/after TDC) thereby retarding the timing, then you can u= se your EM4 to ensure the timing setting in the EC3 for the Advance/Retard= you want when engine is running. =C2=A0Then when you initially start, the f= iring point should occur after TDC by a couple degrees reducing the kick ba= ck probability and once running you can adjust the timing advance once for= you normal operation and be done with it.. =C2=A0

The main point is setting the static timing point so that it occurs af fe= w degrees =C2=A0after TDC =C2=A0on the pulley.

I had an EC-2, and donated my plane to the local EAA chapt= er who sold it to another user, so I no longer have the manual, but I belie= ve it had a programming option for advancing the timing when the engine is= running, so why not RETARD the timing mechanically and then use the advance = system to bring it forward when running?

Another opti= on would be the MegaSquirt/MicroSquirt family of controllers. Seems to be pretty mature tech, and at least in the case of the MicroSquirt, a very compact and affordable package.

Sounds like a low-cost solution. But would require hardware changes and programming.

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
