In 1994 my father in law bought me my first GPS upper right the LowranceHi Mr. Robinson. I asked the question on the forum a while back as to which of the 4 tires the computer took it's reading from for the speedometer. I found that my speedometer was off by a whopping 4 mph. I checked this with a GPS app on my phone, I checked it with the Garmin Nav, and I also chjecked it by the speed radar the DOT places on the interstate at the beginning of a construction site to get you to slow down. I have to run the speedo up to 74 mph to actually be doing 70. So I was asking the question because I wanted to go a couple of sizes taller if I could, and was wondering about how critical the smaller size in the front was to the size on the back. Well to make a long story short RustedWrench stated that the computer takes readings from all 4 tires at once and uses that data to run the speedometer. So I guess the back axle gives the same reading for the back two and the front two would have the same unison reading, but different from the back. I guess of the readings get too far out of whack it can throw the Smart into "limp mode" which severely limits your power and speed until you shut down the vehicle and start it again.I know alot of people on this forum run the same size tires front and back by buying 2 more back rims for the front, so I know you can get by with that. By as to calibration, I don't kow if that can be adjusted electronically or not. DCO
- The blower motor issues were pretty much resolved in the 451 2011+ facelifts.Sorry Sport, exactly how did the problem with broken blower motors 'just go away'? I'm sure the people who paid $200 for a new motor have a different opinion. How about current fuel tank problems? Speakers, subwoofers, sunroofs, ......
Or they become "enhancements"Point is, all cars will have some bugs, and like most products with a multi-year run (operating systems, phones, computers, TVs, aircraft, RVs, boats, etc), those bugs often get ironed out over time with updates and or newer models..
Intelligence test. Everybody failed.please excuse my denseness rustedwrench i'm still in a learning curve on this little car. who would have thought this little car could be so intricate compared to american cars. seems they have a different engineering logic then we do.
but what is number 541?
