Dan, the rewrite involves an alternate conversion method which is more costly (by $80), but doesn't require the tach face overlay. Its maybe slightly less work, (a bit more wiring, a bit less work on the cluster itself). It isn't necessarily a better method, it just avoids the tach face overlay and recalibrating the tach and is maybe slightly better looking aesthetically (the tach is easier to read at a glance).
I will write it up one of these days.
