So I had a dyno test done

[JPS]

To test calibration, and this is what they found...

Speedometer Reading:15 Dynometer Reading:19 Difference:+4
Speedometer Reading:25 Dynometer Reading:29 Difference:+4
Speedometer Reading:35 Dynometer Reading:30 Difference:-4
Speedometer Reading:45 Dynometer Reading:37 Difference:-8
Speedometer Reading:55 Dynometer Reading:40 Difference:-15
Speedometer Reading:65 Dynometer Reading:48 Difference:-17
Speedometer Reading:75 Dynometer Reading:63 Difference:-13

WTF HONDA!

The garage didnt have any idea how to fix this, theyve never seen anything like this...they said its suppose to be a fixed amount off, not flunctuating like this does in the positives and negatives...they said they ran 3 more dyno tests and each time it was different from the previous test.:|

The reason I had this done was because Jackie got a speeding ticket doing 67 in a 55, according to the dyno above, the speedometer should have been reading around 50 at the time the cop got her. So would this be a good defense in court? The place we took it was certified and even had a notary public sign and stamp it(its the same place the police cruisers for the county take their cars to get calibrated)

It would be a good argument in court. But your car will probably be illegal until you fix it. Which you'll probably do anyways.

If your vehicle passed inspection, which it obviously did. Your argument should hold up.

Court defense:

Probably not. Ignorance is no excuse. The fact is, whether you wife knew it or not, she was breaking the law. But I'd suggest you show up in court to contest the ticket, if the cop doesn't bother to show, then you're off. If he does, nothing's changed for you. Unless of course, you planned on going to traffic school to keep the ticket from going on your wife's record and raising your insurance rates.

The unasked question:
Is it grounds for a suit against Honda? Contact a local attorney.

Well I know the ticket will be lowered to defective equipment, I myself have had 2 speeding reduced to defective equipment for the same reason, and Ive had a few friends pull the same ticket with the same outcome, I just wanted to know if you guys feel its a good defense given the odd situation.

If you can prove you were unknowingly breaking the law most judges will reduce your sentence to something a lot less severe(such as defective equipment, just a $25 ticket that doesnt increase your insurance since its a non-moving violation)

intent to break the law is a huge part of being found guilty. since the car had a serious defect, it is very reasonable to argue that the ticket is invalid. however note that your car must be fixed. i would guess that the chip inside is faulty.

ignorance is only a useless defense if you clearly break the law with intent to do so and claim to not realize it was illegal. if jps's wife had of known that the dial was faulty, then this defense would not be valid.

no you cannot sue honda, the defect probably occurred through normal usage wear, rather then honda's neglect. they have good lawyers and youd waste more money and time to get the same dead end result.

Called my dad whos ASE certified, he said to get the speed sensor checked(durr).

Jackie was pacing a tractor trailer for a good 5-6 miles before being pulled over at 60mph(which is a normal speed for that road, but if you go over that theyll stop you) so she wasnt intentionally breaking the law.

State law and its enforcement varies quite a bit. I was pulled over for doing 52 in a 40, I had a defective speedometer, and the cop writing me up placed the citation about two miles behind where he actually pulled me over, which was in a 50 zone. Edit: Maybe that's not clear, where he pulled me over was a 50, but he placed the location on the ticket in a 40. Unfortunately it was the first time I'd been pulled over, and I didn't think to go to court over it or read the ticket closely when it was first written up.
