Bw shaft speed sensor output

[Machineman]

Can anyone chime in on the shaft speed sensor i believe they a variable reluctance Type i wanted to hook this up to my vfiz cluster readout the guy says its doable but he said to post on the forums and see what comes up .

it has 1 pulse per rev and yes its a VR sensor. use LM1815 to convert to 0-5v

 

[Machineman]

Thanks should i use a lm1815n or lm1815m

I have N but datasheet should say what different suffix is. You can look up the type of the sensor. I think newer unit have more intelligent sensor that gives TTL output. The brand is Jaquet.

Ok are you using yours for vfiz ?

 

[Rub87]

No i read directly in ecu so i can see it with vcds

 

[Machineman]

Well vfiz reads whats on the ecu so that would work what input are you using ?

 

[Rub87]

every actuator you delete apart from egr cooler bypass has a analog feeback signal that you can use.

 

[Machineman]

Figured

Going to piggyback on this, can you split the signal as such without upsetting was the ECU see's?

I want to create my next gauge soon and want to use the speed sensor if poss otherwise will do something with an inductive sensor on the crank pulley.

edit: still interested in answer but realised I meant crank sensor....opps
