I thought this page might be interesting reading. Dave is definitely on the right track. http://ourworld.compuserve.com/homep...ition/CDI.HTML
One of the main reasons I incorporated the PIC in my board design was expandability. Dick Hanson posed a question on thermal management. One of the main reasons I used the PIC in my system was so it could eventually include fuel and thermal management. I would be curious to know how sophisticated a system modelers would buy and what they would consider a fair price to pay for it. Thanks to Dave for the coil links. I believe this unit will work but I think their shipping is a bit high. http://www.amazing1.com/transformers.htm I did find a company willing to sell small quantities (that means less than 100 pieces) of coils and I am presently testing one now. I am sure it will only work on a true CDI system because it does not have the turns ratio need by lower voltage systems.
