XF vs EA Tachos
Does anyone know if the tachos from XF clusters are the same spec as EA? I picked one up from the wreckers yesterday, as it was lying on a back seat by itself and got it for $13, but when i try and run it in my EA 3.9CFI as a top-of-dash mounted tacho, it reads about 400rpm or so higher upright (normal position) than when flat. The flat reading seems more correct too (dad's tacho is dead, so i can't check it).
i'm wondering if the tacho is different or if the coil is putting out a different voltage or something. Also, I've read here that redline is about 5500 rpm, but I ran the tach today on Maroondah hwy and I backed off the throttle at a reading of about 3800 rpm as it sounded a bit scary... i'm thinking it was closer to 5 than 4...
Are the ECUs the same between XF efi and EA efi?
thanks for any help guys
