FAST solves one of the last hurdles in making wide-band tuning easy for muscle cars.
I have nothing against high-tech fuel injected engines, but there’s a lot to be said for the simplicity of an old-school hot rod with a carburetor. They’re cheaper, they’re easy to build, they’re easier to troubleshoot, and they make gobs of power. You can build a traditional powerplant and have it running strong months or sometimes years before a comparable EFI motor even sees fire in the hole.
So is that the end of the story? It turns out there are lessons to be learned from the EFI crowd by even the most ardent old-school curmudgeon. The black art of reading spark plugs, reading idle vacuum, and even gazing at EGT readings has been superseded by the stupid-easy process of tuning with a wide-band O2 sensor. In fact, that’s the biggest secret of the EFI religion. Regardless of whether you’re using EFI or a carb, a wide-band is the quickest way to perfect your tune, but until now, it hasn’t always been the easiest.
Fuel Air Spark Technology (FAST) has just come out with an ingenious bracket that eliminates the last obstacle—the fabrication of a sensor bung—to using a wide-band sensor. FAST’s EZ Clamp-On Sensor Mount (part No. 170620, $59.95) provides a quick and temporary mounting bracket for a wide-band sensor, without requiring any drilling or under-car welding. Just clamp it temporarily to your tailpipe, and screw your wide-band sensor into it. When combined with a wide-band sensor kit, such as FAST’s part No. 170401 ($466.60), the EZ Mount can give you valuable tuning information in a hurry without the fuss of a permanent installation. (You can also use it on a bunch of carbureted cars, and only pay for it once.) You can now find that ideal secondary jet, pump shot, or idle mixture setting in just minutes while keeping your hands clean at the same time!
