While holding the button, start the vehicle and continue to hold the button until the pointer sweeps to full scale and stays at full scale. You may now release the button.
Is it possible to recalibrate speedometer?
Electronic speedometers are easy to calibrate. Manufacturers always provide the distance of the test drive needed for speedometer calibration. This information is normally available in the owner’s manual. Identify the speedometer calibration button and press-hold, crank your vehicle and then release the button.
Can you switch tunes with autocal?
You’ll have to buy a new autocal. Your current one is licensed to the v2 that tuned it.
How much does it cost to recalibrate your speedometer?

How do I get my speedometer calibrated?
Press and hold the calibration button located on the speedometer, start the vehicle, and then release the button. Press that button again and then take the test drive. Once you have driven the distance needed, press the button once more and the speedometer will calibrate itself to accommodate the new tire size.
How do I know if my speedometer is accurate?
Testing Speedometer Accuracy Get your hands on a stopwatch. As soon as you pass a mile marker on the highway, start the stopwatch. Then, stop the watch when you pass the next mile marker. You can take the second hand of the stopwatch as your speed.
How often should speedometer be calibrated?
In general, you should consider calibrating your speedometer if you are charged with a speed that is within three or four miles per hour of a couple critical marks: The reckless driving limit. Reckless driving is any speed over 85 mph or any speed that is 20 mph over the speed limit.
Does putting bigger wheels on your car affect the speedometer?
You might ask: do bigger tires make your speedometer faster? The answer is no. Tire size and speedometer accuracy are directly linked to each other. Up-sizing, or installing a taller tire, will lead to a speedometer reading that is slower than your actual speed.
What is EFI Live AutoCal?
EFILive’s AutoCal device is intended to provide a convenient platform for professional tuners to distribute custom tunes to their customers. And for their customers to collect and submit logged data back to the tuner for analysis.

Reasons why your speedometer is inaccurate Damaged wiring or a blown fuse could be enough to through the speedometer out of whack. A malfunctioning sensor or engine control unit could be reporting an erroneous speed. A change in wheel or tire size could even throw off the senor and its calculations.
What is car calibration?
Vehicle calibration essentially consists of determining the attributes of a car for fulfilling legislative standards as well as refining the car´s character to meet all the driver´s expectations for best driveability and comfort.
Which is more accurate speedometer or GPS?
Speedometers are not allowed to read lower than the actual speed of the car, but they are permitted to indicate a value that is 10% higher than the actual speed, plus 4. GPS, on the other hand, uses a purely mathematical technique to measure the speed of the vehicle and is therefore more accurate than a speedometer.
How can I speed up my speedometer?
It turns the driven gear, a pinion gear that is connected to the end of the speedometer cable. Changing the ratio between the drive gear and the driven gear will change the speedometer reading. A driven gear with fewer teeth will speed up the speedometer reading; more teeth will slow down the reading.
Is Waze speedometer accurate?
While every good driver keeps an eye on their speed, Waze Regular has usually noticed a difference between the km/h displayed on their computer and that shown by the app. The discount is that manufacturers overestimate it a bit, on the order of 5% of your actual speed.
Is the Google Maps speedometer accurate?

Do all car speedometers overread?
Can you trust your car speedo? Car speedometers are not allowed to ‘under-read’ – they can’t tell you you’re going more slowly than you really are – but they are allowed to over-read by up to 10 per cent plus 6.25mph. So they could read 50.25mph at 40mph.
How accurate is a car speedometer?
So if you’re going 40mph, your speedometer may read up to 50.25mph – but it can never read less than 40mph. In order to stay within the law, carmakers calibrate their speedomters to slightly overreport their vehicles’ speeds.
What does certified calibration mean?
A calibration certificate is a document that contains information about a device’s calibration. This certificate provides valuable information on the quality and measurement accuracy of the device. Depending on the calibration of a device, its cost also changes.
