    I noticed that my mondial's speedomter has a huge amount of error in it. It says I am going 5 to 10mph faster than I really am. I have stock tires and wheels so its not that. While I know it could be considered fun that my car is going "faster" now with this unwanted "mod", does anyone know how I can adjust this? I did a search and only found comment about a sending unit. Is that my only avenue?
    Thanks in advance

    Buy a German car...?!?

    LOL...!

    Sorry, i don't mean to joke, but Italian cars are notorious for things like that - ESPECIALLY the Mondials...

    I have had 7 Ferraris (still own 2). All the speedos were off, always generous. A couple were way off. My current 89 328 is about 5 MPH high at 60. My new 430 is only a couple of MPH high. Checked with radar, it's doing 58 when it says 60. A friend of mine with a 348 that was way off did get his calibrated by someone in New Mexico (Me-Ma-s?) and is now much better. For 5-10 over, I would just accept it. Oddly enough, my Subaru STI is also about 5 MPH over and the Lotus Elise I owned was also over. Perhaps it is a performance car thing!

    All cars have optimistic speedometers. If you read 60 - count on 56-58 for most cars including all the new ones as well. The variance increases as the speed does. Any variance greater than that is excessive though.

    No (speaking from experience), I replaced the sender in mine and still 8mph or so high when showing 50mph (actual speed is 42). Sender made no difference.

    I find the speedo in my 328 is just about 10% high at all speeds - which actually makes calculating true speed relatively easy.

    One thing I have done with each Ferrari is take a stop watch and travel measured miles to calculate the actual MPH in high gear using the tach which is generally more accurate. Earlier manuals will list MPH/1K RPM in each gear. Generally, most 3X8's do about 60MPH at 3K and so on. I generally do not even look at the speedo, just the tach as a speed indicator. The measured mile will also tell you if the tach is off significantly which is not uncommon on 3.2 powered cars. I would do these measurements in several different places, however, because mile markers can be off too! Some people use portable GPS units to calculate speeds as well.
