Yes, this is not a CDI it is a TCI (Transistor control ignition), the way i understand, this circuit keeps the coil energized and releases the negative at the ignition point, creating the spark. If i turn my ignition switch on and do not start the engine, the coil will receive continuous 12v from the battery. You understand better them me this circuit it appears rsrsr, correct me if i´m wrong ... I search for the datasheet of the IC and the only thing about it i found was this: "The M59201P from MITSUBISHI manufacturer is a Amplificador Linear Devices with Winchester Servo Preamplifier with Low Current Drain"
My question is 1): can i just plug my pickup coil to my VR conditioner (there is pictures of it here)?
2) How will i setup the crank sensor on TunerStudio? Just dumb coil? What else?
3) Is it a good option to just use my old TCI box as a "VR conditioner"? The idea is to get the output that would go to the coil, reduce the voltage to 5v and them feed this into a 74LS04 inverter logic chip, so i would get a rising edge digital signal?
The box dos some timing by itself, as PSIG sad and i think so... For the ignition part of Speeduino i think this would not be a problem, instead of advancing in lets say 5000rmp 35 degrees i would have to advance in Speeduino just 10 because the box already is giving me a 25 degrees advance... But what about the injector? This would be a problem ?
4) Finally, if anyone have some advice or suggestion on how to make it work with my original setup, i will deeply appreciate and i will post everything i can about it, configs done, map, prints, photos of how i did etc.
Thank everybody that are helping me on this journey.

Only a 300V transistor and I don't see a high voltage cap, is it really a CDI?
