got a M3 cluster in and I swapped over my old tach face plate onto the M3 tach (and coding plug).
In addition the M3 tach was inop, so I actually used the old tach mechanism from the iX on the M3 one after seperating it from the econogauge by simply cutting the ribbon cables that connect it and cutting 4 of the unused prong plugs.
I am still just not sure if the tach is correct or not. Idle seems the same, around 700-800. But today I got on it and it reved way past 7k and into the oil temp area. I was on the highway later doing 80mph on a flat section and the tach was showing a shade under 5k. Does that seem right? Can someone simulate that next time you are on the freeway so I can get a comparison? Thanks.
