can someone tell me what the Transistor Trick is or where i can read up about it thank you

 

tons of stuff on here. https://www.rx7club.com/1st-gen-archive-71/ignition-2gcdfis-w-tt-transistor-trick-write-up-simplified-design-484176/

Those threads will keep you busy for awhile. Basically it allows us to use the 2nd gen coil and ignitor without a ECU. The circuit converts the signal that the stock ignitions uses so that it will work with the normally ECU triggered 2nd gen coil. The 2nd gen ignitor/coil combination produces a hotter spark and keeps firing strong at high RPM.

The one in the first thread listed is good, but we had found that the ignitor on the 2nd gen coil gets too hot (shortens the ignitor life). I have a new circuit developed now that should fix that. You can read about the newest circuit at the end of the second thread posted. I had some circuit boards made of the newest design, so if you end up wanting one, go ahead and contact me.
