Another new person with old questions. I have a Mazda 323 GTX turbo engine with Bosch 0221604800 cop 4 pin that are 387 ohms and I believe it requires a 5v signal. I have the early CAS (intake side). Is this the correct way to configure a coil driver circuit? There seems to be several different opinions or if there is a more current suggestion. This is the explanation of the twin cam 4G63 and 4G9 Eclipse/ Talon / Lazer https://www.msextra.com/doc/ms1extra...nual.htm#cop30 All help is appreciated but just gear your answers toward someone who might be considered a little more mature in age.
