Hi, here's my problem,
I had a hall effect speed sensor on my car which, didn't work.
So I replaced it with an universal one because the original is out of production. There's no problem till this point, my old speed sensor has the following specification: 12v 16imp(pulse).
My new one is: 5-12v 4 pulse per revolution.
I red this before I bought the new sensor, but I wanted to see if my old one was calculated with 4 per rev, so it would be 4pulse per 4 rev= 16 pulse, but I was right thinking it was 16 pulse per rev ( a bit high :]]]])
I tested the new speed sensor and when the speedo was reading 20km/h
With the OBD2 the ECU was reading 4km/h ( I know I said the new speed sensor is 4 times lower but the speedometer needle remain a bit high, it starts about 3km/h instead of 0km/h so with the possibile calibration error of the speedometer it should be 16-17km/h which is right).
Made this premise to say that I need a speed sensor pulse multiplier which have to convert the 4 pulse from the new speed sensor to 16 for the ECU.
I forgot to say that I have a cable driven speed sensor, the speed sensor attaches on the gearbox on one side and on the other side there's the attachment for the speedometer cable, and in the middle the the hall effect sensor with 3 wires that are: Ground, Vcc+ and signal.
I need something that works, it's cheap, not too big cause I have not so large spaces, something easy to build ( well, that's not really a problem, I can try and I like build circuits I can), if it need programming plese link me a Premade software.
Thanks.
