That makes no sense to me… I guess the stock cluster is inaccurate to some extent on speed. I have fine tuned my MPGuino to be dead on with the GPS speed which is a much better method.
I've found that the springs on these older Honda clusters tend to get weaker over time which results in the speed reading high. To fix this on my cluster I simply popped the needle off and stuck it back on 3mph lower.
