The dyno operator is having a hard time picking up my rpms. He suggested we tap into the rpm signal wire.

Has anyone ever hooked up a tach to the Diagnosis Connector?
I'd like to be able to compare the dyno data with my datalog file.

thanks, Dave

 

yes, in the diagnostic box use IG-

 

thanks...I was wondering if you had actually hooked it up to that terminal...I see in the manual where Mazda hooks up a piece of their special test equipment...want to be absolutely certain...don't want to fry anything, especially my PFC
