    View attachment 2918344 View attachment 2918321 In converting/calibrating my original 308 gauges to the F355 motor, my tach will not read above 3200 rpm. It reflects an accurate idle speed with instantaneous throttle responses but for some reason it just won't read higher than the 3200. I spoke with the shop owner yesterday and he told me that my ECUs need to be reprogrammed but I'm not convinced, does this make sense? I'm not so sure the tach was rebuilt correctly, ugh.

    BTW: If anyone wants to know, a 308QV speedometer IS COMPATIBLE with the F355 speed sensor as they both share the same Type II sensor. Mine works fine, thank you Adrian!

    Thanks in advance for the input.
