Frequently Asked Questions

Yes, the pre-terminated harness and ECU included in the FiTech 35571 kit are engineered to connect directly to both 24x and 58x crank reluctor wheels and 1x or 4x cam sensors on GM LS engines without extra adapters.

The integrated ECU includes electronic transmission management for popular GM 4-speed automatic transmissions, including the 4L60E, 4L65E, and 4L80E. Shift points, shift firmness, and torque converter lockup can be adjusted via the handheld touchscreen controller.

The Force Fuel Mini surge tank mounts under the bonnet and is supplied by your vehicle's low-pressure mechanical or electric fuel pump. An internal 255 LPH pump inside the mini surge tank feeds high-pressure 58 PSI fuel directly to the throttle body, avoiding the need to modify or replace your fuel tank.
