As the car is right now with the 195/60-15's at higher speeds <cough>, the speedo is 5mph off, I've been <cough again> informed (reads high, thank god!! lol) I'm about to put on some 205/40-18's, and they are a lil bit smaller than the stock ones, anyone know how adjust the computer output for that (or any mechanical means of accurately adjusting it)?

 

if the car has a VSS, then the local honda dealer should be able to calibrate the unit for you. I had 2 accords and I found it funny that both were exactly 3mph off and one was a '94 LX and one was a '98 LX V6

 

I'm trying to avoid that, atleast untill I get my other car up an running. anyone know how much they'll charge for that?
