OBDII
There are a lot of new products that plug into your OBDII (On Board Diagnostics) port and claim to measure horsepower, torque, 100m etc. We have studied the OBDII protocol and the problem is that OBDII system was designed as a diagnostic tool to be used in a mechanics shop. So things such as timing accuracy and speed of the sensor readings were not critical. But for performance measeurements you need exactly those things. So when it comes to measuring performance through OBDII that is a problem.
If you want an OBDII diagnostic tool
in order to read the vechicle CPU information you can check ScanGaugeII. You can learn more at www.scangauge.net
For performance measurements you need acceleration. OBDII devices calculate the acceleration from speed and time. In theory there is nothing wrong with that method but the problem is resolution (how often is the speed updated?) With OBDII it's only a few times per second! So acceleration readings are "choppy" and not accurate.
The best way to get accurate acceleration is to measure it with an accelerometer. GTECH takes 4000 readings per second from each of its x,y and z precision accelerometers!
