Another motivation for using the Infinity 8 EMS is its four channels for wheel speed which can be used for traction control. Again, in most any other four cylinder-powered 240SX application, the two wheel speed inputs for traction control of the Infinity 6 EMS would more than do the trick.
In order to take advantage of the traction control capabilities of the AEM Infinity 8 EMS, 5523 Motorsports swapped out the front spindles for ABS spindles which accommodated the wheel speed sensor. In addition, a ABS ring from an S14 was installed on the hub.
Essentially, the infinity 6 EMS is a two channel system taking input from one front wheel and one rear wheel. The Infinity 8 takes input from all four wheels. In our case, we went with a single rear wheel speed sensor since we have a welded differential. However, a four channel system is possible by using a Z32 300ZX diff cover with individual wheel speed sensors.
In both cases, a slip differential can be established by comparing the driven wheel speed and the drive wheel speed. Once the drive wheel (rear) speed exceeds the driven wheel (front) speed, throttle, ignition, fuel or a combination of the three can be progressively cut with the assistance of the Infinity EMS' built in traction control system.
