Fuel Air Spark Technology Mechanical Timing

Most any distributor can be used with the FAST system as long as the mechanical timing can be locked out since all timing functions are set and controlled by the XFI box. This is a dual-sync distributor from FAST. The FAST dual-sync distributor also has a cam sync that allows sequential injection instead of simply squirting bank to bank. Cam sync tells the XFI which cylinder is firing so it can control each injector individually. On a mild engine like this, either method works great. It's when you get more radical and especially with blown, turbo, or nitrous applications that it's nice to have control over individual cylinder's A/ F ratios and timing.
