FAST ECU Main Connector Kits

FAST ECU main connector kits include all main connectors and terminals used when connecting a wiring harness to a FAST ECU/ECM. Environmentally sealed Weatherpack connectors were originally designed to withstand exposure to extreme temperatures, moisture, and harsh engine compartment fluids and chemicals. They are heavily used by OEM automobile/truck, construction, off-road, and farm equipment manufacturers due to their high-quality and excellent fitment.

FAST Magnet-Free Crank Trigger Kits

Recently, engineers at FAST turned to the OEMs to see what they trust in the way of rpm-measuring crank triggers for their 400 and 500 horsepower daily drivers. Until now, flying magnetic trigger wheels with bulky inductive pickups have been used with the risk of broken magnets or losing magnets at high engine rpm. Now there is a better answer--FAST magnet-free crank trigger kits. A magnet-free device, these kits from FAST include a wheel constructed from ASTM A36 grade steel that is so strong that it only needs to be .125 in. thick and is virtually indestructible. With the wheel being this thin, it not only weighs less but requires less space than competitors' aluminum versions. And the FAST inductive sensor is also much smaller than others on the market and is hermetically sealed with the connector molded into the body. The key to the crank trigger's dependability and accuracy lies in the trigger wheel design. Rather than having added magnets, the wheel has tabs on the outer rim. These tabs are measured by the inductive sensor as the wheel revolves, which then provides data to the fuel injection and ignition systems for accurate rpm measurement. And because the tabs are a part of the single wheel unit, there is no possibility of loss or fragmentation as with the magnetic style trigger wheels. This sensor is used by OEMs both on and inside the engine and provides long-lasting, accurate timing. Installation is straight forward, and everything required is included. For those already using the FAST XFI system, it's a plug and play unit. In addition, it's compatible with many other EFI systems on the market.

FAST Magnetic Crank Trigger Kits

FAST magnetic crank trigger kits are setting the new industry standard for timing accuracy while preserving compatibility with other brands' ignition systems. Crank triggers are known to provide the most accurate crankshaft rotation measurement; however, modern fuel injection systems and sophisticated testing equipment have exposed inadequacies in traditional crank trigger designs. To correct for timing fluctuations in high-rpm racing applications, FAST engineers replaced the fluctuation prone 2-wire inductive pick-up with a modern digital hall-effect design. This digital hall-effect pick-up, coupled with samarium cobalt magnets installed in the trigger wheel, result in crank rotation measurements that are accurate to a quarter of a degree from zero to 13,000 engine rpm. These pickups are far less susceptible to electromagnetic noise interference than 2-wire designs. Additionally, the pick-up accuracy is unaffected by electrical system voltage variations—maintaining quarter-degree timing accuracy from 7 V to 30 V DC. Outputting a clean square-wave signal, FAST magnetic crank trigger kits can trigger ignition boxes directly or integrate with EFI systems such as the FAST EZ-EFI 2.0, XFI Sportsman, and XFI 2.0. An integral LED eases timing calibration and diagnostics. These kits don't sacrifice durability for technological innovation. Crafted from billet aluminum then black anodized, the trigger wheels and pick-up brackets will withstand harsh racing environments. OEM-quality braided wire wrap protects the pick-up pigtail, while a weatherproof Deutsch connector terminates the harness. Order the kit recommended for your year, make, and engine application.

FAST Diesel Nitrous Systems

FAST diesel nitrous systems boost power, reduce EGTs, and cool the air inlet charge for your diesel engine. Featuring adjustable power from 35 to 200 additional horsepower, these diesel nitrous systems reduce turbo lag and greatly lower inlet and exhaust temperatures for additional power and engine safety. FAST diesel nitrous systems add power with no additional tuning but really come alive when used in tandem with other performance components like power programmers and high-flow exhaust systems! Each kit includes a bottle, brackets, nitrous solenoid, electronic throttle activation switch, and all necessary plumbing and electrical connectors to facilitate installation. Compared to other performance modifications, nitrous systems can be a relatively cost-effective way to achieve significant power gains. Order the kit for your application needs.
