At 200km/h your more likeley to have a judgemental or a paralax error while reading.
Which brings me to another point... gen2 clusters are extremely bad for paralax errors due to curved nature of the indicator strip and the angled front perspecs

Knew you'd say maths is a science :-P depends who you ask.
As someone who's studied maths and physics at uni, I say they are different. Science is applied mathematics but that's beside the point.
Evenly spaced. Hmm luke what's the next excuse? :-P

on my ultra gauge with stock everything the faster i went the more it was out. at 110 ultraguage
the speedo needle is at 119 in gen 2
Sorry to say it luke but I think you must have alcams speedo. It's superior than everyone else's and works better the faster you go

I think I may buy an Ultragauge or one of these Elm327 WIFI Wirless OBD2 Car Diagnostic Reader Scanner Scan Tool for Iphone iPad iOS PC : Amazon.com : Automotive and hook it up to my iPhone.
Thoughts?
Connecting via iPhone and wifi is crap and laggy. Only good for logging no point watching it. You need an android, Bluetooth and torque to be able to watch live with accuracy. I've tried everything with the iPhone, all types of wifi adapters suck. Some are better than others but in the end to be able to do it optimally you want to go the android route.
Ultragauges are great, but as soon as you change you wheel size, it makes them both go out
This is what happened with my car
18" stock rims
Actual Speed - 100
Speedo - 109
Ultragauge/Cobb AP - 101
19" rims
Actual Speed - 100
Speedo - 105
Ultragauge/Cobb AP - 97
Cobb told me there isn't any way to recalibrate the ECU to compensate wheel size
I'd have to recalibrate to speedo or my brain to get any accuracy
came across this...
Direct from the Mazda Australia FAQ page
Why is the speed nominated on my GPS different from my vehicle's speedometer?
Mazda Corporation goes to great lengths to ensure all its components comply with both Mazda product performance guidelines and the Australian Design Rules. The current Australian Design Rule (ADR 18/03) indicates the speed shown on the speedometer must always be equal to or greater than the actual vehicle speed. ADR 18/03 allows approximately 10% variation at 100 km/h. For more information refer to the Australian Government, Department of Infrastructure and Transport website.
Whenever a speedometer is tested and found to conform to the relevant ADR, it is deemed to be within specification and not subject to any further rectification. For speedometers components operating correctly, there is no further calibration adjustment available.
Almost. It's 10% + 6kph.
2. Requirements
The production shall be deemed to conform to this Regulation if the following relationship between the speed indicated on the display of the speedometer (V1) and the actual speed (V2) is observed:
In the case of vehicles of categories M and N:
0 = (V1 – V2) = 0.1 V2 + 6 km/h;
sounds good. last bit made me laugh.
although the whole lot is correct. it doesn't take into account the heat incease, pressure increase and circumference increase that happens at higher speeds. which is probably why someone may see less percentage varience at higher speeds.
haha how'd i miss that the first time.
This thread... Makes me giggle lol
maths not science? Ha! Bahahaha. Ha! Oooh that made me laugh.
