C&L vs. Pro-M Meters

[2FastLX]

I had a C&L and it worked fine for me. I've never had any experience with Pro-M so I can't say which is better, but a friend of mine swapped on a C&L at the track and gained a tenth. The Pro-M was a 75mm and the C&L was the new 76mm. He said it idled better too it seemed. I just never liked the idea of having to pay $100 for calibration if I needed to upgrade so I went with the C&L. And the folks at C&L seem real nice on the phone. You'll get a lot of comments on both meters, but here is some info C&L has on their web site concerning the "tricking" that most people slam C&L about...

"The purpose of changing the MAF calibration for use with larger injector sizes is to make the computer think that less air is actually entering the engine. By doing this, (which ALL aftermarket meters from ALL manufacturers do) you are making the computer reduce the duration of time that it is opening the fuel injectors at a given air flow rate. The larger the injector that is used, the more the voltage is dropped, and in return, the shorter the time the injectors are pulsed by the computer. This "tricking" of the computer is how a MAF allows the consumer to use a larger fuel injector than what originally came on your vehicle from the factory. Over the years, we have heard that people have said that our unit "tricks" the computer and that our competitor's method does not. This is truly ludicrous, as the only way that you can calibrate a meter for larger injectors is to reduce the output voltage, and ALL aftermarket air meters use this method to "trick" the computer. The most important thing to consider is that changing the calibration for larger injectors must reduce the voltage to the proper level for the ideal air/fuel ratio. We have spent countless hours on the dyno and at the track to ensure that our calibrations will deliver a winning combination."

I like that paragraph
