Change to different car-Weird numbers
« on: December 23, 2012, 01:07:57 PM »

I just sold the car that had my Ultra-Guage, so I put it in my other vehicle. I originally had it in my 08 KIA Optima, 2.4L 5-sp Auto. I moved it to an 06 Mazda 5, 2.3L 4-sp Auto. Before I made the switch, I restored the factory defaults, to remove the information about the KIA from the Ultra-Guage.

The difference in % Engine Load between the cars is significant. In the KIA, when "already-warm" idling, the % Engine Load was generally 8-10%. With the Mazda, it is at 24-26% at warm idle.

Can there be that much difference between how these engines are set up?

Can someone please explain in more detail than the manual how the % Engine Load is calculated?
