Hi
i know that this is probably not the best place to look for help but i have been to a lot of forums with no real result . The problem i have is that we changed the motor on my car form a 4 cyl 2l witch gave me 2 pulses per revolution to a 2.5 v6 but this motor gives 3 pulses . its form a separate wire from the ECU . the only other info i have is that the signal does not come from the coil on the car , at idle the signal is 25 Hz and above 2500 rpm its 125Hz . to give a idea how mutch its over reading with the old motor at 120km/h in top gear it was sitting at about 3500 rpm , same speed on new motor its about 5500 rpm . the info i got was that i need to divide the signal by 1.5 and that Possibly a 4046 cmos part with x4 output and a bit of logic to divide it back down by 6 would do the job.
The main problem is me because i never had a chance to learn about electronics , the only time i can build something is if i have a diagram .
Thank You for your time
