The TB Dev FCD is an electronic device developed to properly raise the factory fuel cut level, on factory turbocharged vehicles, to a safe and higher predetermined point. As modifications such as intakes and exhausts are made to optimize engine performance along with utilizing a boost controller to further raise boost levels, the conservative factory fuel cut is often triggered by the higher boost levels which activates a fuel delivery cut off as a failsafe procedure. Symptoms of fuel cut are often expresses as hesitation, bogging, and/or illumination of diagnostic indicators. The electronic signal from the Standard Map sensor is altered by the FCD to raise the fuel cut level to accommodate for the additional boost without triggering fuel cut and/or an engine diagnostic light, although not completely removing this safety device just raising the limit to allow high boost levels to be run.
This device is aimed at the rev 1/2 turbo customers who want to run 15psi of boost , needing this to over come the standard 13psi standard Fuel Cut.
