I'm having some problems with my speedometer after the K-Pro installment on my '06 DC5. I tried driving side-by-side with my brother on the freeway and doing a speedometer comparison with his ('06 EX) Civic. I have found that the speedometer read for my car is WAY off from my brother's Civic. As he went 65mph, my speedometer read 100mph; when he went 60mph, mine was at 90mph. My speedometer is just way off on accuracy. In addition it is adding mileages much faster than before. So '05-'06 K-Pro owners, what were your settings for the K-Manager (on the Miscellaneous tab) for this issue? The current setting is at 50%.
