Howdy guys(gals)

With regards to lucas/bosch efi as used on Jaguar xjs. Does anyone know what
the speed pulse looks like . This pulse originates at the ignition amplifier,
and is a direct input to the ecu. Would like to know p.w., amplitude, etc. I
have an intermittent failure which shuts down my injection events. I have
isolated this to the eng. rpm signal but do not know what the signal should
look like .
 
I appreciate any help .

Thanks, Jeff
