Title: Speedo and Speed Sensor???
Post by: techie on August 08, 2005, 08:59:20 AM

Trying to find a speedo with a speed sensor form my Sami. Put in a 16v and the speedo went, sensor still works, I guess, cause I don't stall. My Q, will any suzuki speedo with a sensor fit in the Sami Instrument cluster and work or am I stuck with finding one for the year of the enginge?

Any should work, all they are is a reed swicth, the magnet which is in the round thing next to it just pulls the contact together making a pulse, so I would say that they are all the same or close enough.

Wouldn't this depend on the year? The OBD1 stuff would work with a reed switch but doesn't the OBD2 use the reloctor (SP?) wheel input that is something like 4x the pulses of the read switch?

HTH, -Eric

I ripped around in my off road Kick for a long time without a speedo / instrument panel and it worked fine. It just seemed to run a little rough down low, but that was about it.
Apparently the speedo sensor ( reed switch ) lets the ECU know when the motor is accelerating/ decelerating or at idle and makes small adjustments to fueling.
Putting an instrument panel back in did help it to run better though ( it developed a small hesitation down low. Felt like the engine was loading up a little :-\ ).

I unscrewed a reed switch assembly from a Kick speedo and screwed it into a Sammy speedo for a project i was working on - too easy, all the holes etc where already there. They just hadn't been used until then. Ran a couple of wires off the switch to the ECU and hey presto - all done ;)

These experiments where on an early model Kick though - 92 model. I believe the later model stuff is a bit more complicated ( only what I have heard though ) :-\

I just thought that he would be messing with an obd1, otherwise with messing with the gas tank sensor and all on a obdII system why would he be asking a simple question about vss,I dunno?  ;D
