ECU RPM signal convert to pulse - Help please.

[MAD7BOY]

Hi,

 

I have an Evo 8 in which I have fitted a mini digital dashboard intended for a bike. It has an RPM graph and dual stage shift lights. It was intended to pick up the RPM signal by induction from the HT leads but this signal is unreliable on the coil packs of my Evo.

 

So I'm looking to be able to convert the RPM signal on the RPM wire of the ECU into a pulsed signal which my digi dash can use.

 

Anyone got any clues on how to do this? Is there a product that does this or will I need a custom circuit or what? Does anyone have any info on what format the signal will be in from the ECU?

 

All help apprieciated.

 

Cheers.

I assume you've asked on the MLR Ben? I members are quite knowledgable so will probably have some good ideas. Just prepare for the stupid ones too!

Oh and moved. Although a technical topic, its not about a 350z
