I normally don't blog company press releases, but FAST came out with a self-learning fuel-injection conversion specific to '72-'90 Jeeps with the inline-six engine.
No word on street pricing or emissions legality, but if they want to remain competitive in the market they'll have to hit it in the sub-$2,000-range and have emissions-compliant options on the table. Here's the company spiel:
The new FAST™ EZ-EFI® 1972-1991 Jeep CJ/YJ 4.2L/6 Cylinder Kit is engineered specifically to deliver modern EFI benefits to older 6 cylinder Jeeps at a value price. An exclusive FAST™ adapter plate for the throttle body eliminates the need to replace or modify manifolds, making this the only truly easy, bolt-on EFI kit for Jeeps on the market today. Using EZ-EFI® technology, the system is completely self tuning; there is no laptop or tuning experience necessary. Once the system is installed, it tunes itself as you drive. The kit contains an adapter plate and a 2 injector 4-barrel throttle body, weatherproof ECU, wiring harness, hand-held device and everything required for installation. Perfect for highway or off-road driving, these kits are available with either an inline or in-tank fuel pump.
