I saw some video on youtube and it just barely caught my eye that he had RPM's listed in the information slot... I've been reading and trying to figure out how to do this forever, and I feel like an IDIOT but for the life of me I can't find out how to do it haha.

BTW it's a 1994 Sedan Deville

Any help's appreciated

 

All you have to do is keep pressing the INFORMATION button until you see ENGINE RPM appear. I have a '97 DeVille with the digital dash, so the one in a '94 should basically be identical. By pressing the INFORMATION button you should be able to view: MPG AVG, GAL FUEL USED, AVG MPH, ENGINE RPM, BATTERY VOLTS, COOLANT TEMP and OIL LIFE LEFT. You can also cycle through all of the messages so that it will not show any information.

 

depending on your car system, you may have to chose ECM data, then cycle through that until you see rpms, degree, volts, etc..

Hey I want the RPM data to show but its not there when I cycle my INFO button. How do I select it from ECM data?
