Traction Control

Traction Control

ProEFI’s state of the art traction control provides the flexibility to be used in any racing venue. The tuner can set up the traction control to be front and rear wheel slip differential, driveshaft/vehicle speed dependent, or based upon the engines rate of acceleration in each gear.

Wheel Speed Differential– The wheel speed differential traction control monitors driven vs. non-driven wheel speed and controls the maximum amount of slip from the driven wheels. The allowed slip percent can be adjusted based on a launch timer to allow maximum acceleration from a standing start, as well as dialing in a maximum slip percentage based upon any conditions. The tuner can select either a fuel cut, ignition cut, ignition retard, or a combination of the three. Using the ProEFI’s one of a kind fault management, the tuner can also tie other activities based upon the amount of wheel slip, things like turning on a warning light, disabling nitrous control, turning the boost pressure down, etc…

Engine rate of acceleration– This strategy is designed more for manual transmission cars. The engine rate of acceleration is broken down by each gear, limiting the engines rate of acceleration in rpm/sec. Unlike other engine management systems, you simply set this one up by entering your transmission gear ratio’s, tire diameter, and final drive ratio. Then the tuner simply dials in the allowed engines rate of acceleration in each gear! The tuner can select either a fuel cut, ignition cut, ignition retard, or a combination of the three. Using the ProEFI’s one of a kind fault management, the tuner can also tie other activities based upon the amount of wheel slip, things like turning on a warning light, disabling nitrous control, turning the boost pressure down, etc…

DriveShaft/Vehicle Speed – This strategy is designed more for automatic transmission cars. The tuner can select either the rate of engine acceleration allowed at a given vehicle speed, or the maximum driveshaft rpm allowed against a launch timer. The rate of engine acceleration by vehicle speed is a strategy a high horsepower, traction challenged automatic car would use for street driving conditions, while the driveshaft rpm control would be used in a drag racing situation. When an input is triggered, usually from a trans brake release or brake pedal release, the computer starts a timer and monitors the driveshafts rpm against that timer. If the driveshaft RPM exceeds the limit, then power reducing strategies are activated. The tuner can select either a fuel cut, ignition cut, ignition retard, or a combination of the three.
