Off the topic but................
In 4EFE ECU, Water temperature, Engine RPM and speed signal is there on pin no 3,21 and 13(CON2) respectively.
Can u tell me their signal types?
For RPM and speed ,is there some voltage propotional to parameters or it pulses out in particular ratio for RPM and speed (Like 4 pulses per rev and 200 pulse per 100 RPM)?
Similarly,for water temperature sensor out, is it direct ouput of NTC or it gives out after some conditioning?
