Okay so I've searched till my eyes bled. I just put 215/45R17's on my car. Now since the MSP runs this identical set up what is the difference that lets the MSP read the correct speed but the ES to read 3 mph slower?
So my results show that the signal comes from the two from ABS sensors. So since I don't believe mazda put different size ring gears on the hubs and sensors on the MSP that leaves either the ECU or a speed sensor in the tranny. The auto tranny in my ES has a dummy plug and rock auto is showing part#'s for the speed sensor.
I just want my speedo to read right because i'm going to forget one day to do the math and get pulled, and I want my OD to ready right too!
Any ideas or help would be greatly appreciated!
