Adding front and rear lateral accelerometers

Post by Canyonfive »

I'm looking to do stability calculations per axle. Has anyone else done this? Aim sells some but doent include their spec sheet. I dont we have total yaw rate internally but I wanted to do it for front and rear axles independently. [/i]

You have two choices:

* Accelerometers with 0-5v output (for RaceCapture/Pro integration)
* CAN bus based accelerometer, which can be integrated via RaceCapture's CAN bus.

Either way should work for you. We don't have any sensor parts to recommend, but let us know what you find based on your research.

Thanks!

I went with one of these https://www.adafruit.com/product/163

$15 plus shipping 5v, outputs 0-5v -3g to 3g in 300~ millivolt increments. At 50hz

My racecapture is mounted in my dash so I'm going to try with just this one additional one. My hope is

Front lat g < rear lat g = understeer
Front lat g > rear lat g = oversteer

In a virtual math channel for easy oversteer/understeer identification in the data. Either for myself or codrivers.
