Upgrading from a Megasquirt DIYPNP to a MS3Pro Ecu this winter so I have more options for inputs and outputs. The biggest one I'm looking into doing is traction control. I know the easiest way is to upgrade to SN95 spindles and use the antilock brake bracket for the front wheel sensor, but I have three full sets of 4 lug tires and wheels, so I'm not interested in going 5 lug. I've found some information on guys making their own brackets for a hall effect sensor and using the back of the wheel studs as pickups. But from what I'm reading, it doesn't work great at low speed. You need a reluctor wheel with more teeth. Has anyone modified a sensor wheel or had one made to work on a stock 4 lug brake disk?
