what's a sample tube?

[Jason 302]

Excuse my stupidity, but I've read in mags, when the MAF sensor subject comes up, they talk about sample tubes? 19 lb and 24 lb and so on. What are they talking about? I thought they where calibrated electronically for different injectors and they're talking about tubes?

c&l maf meters use a "sampling tube" to calibrate your stock electronics to the new injectors. all maf meters have one, it's just most are built into the housing whereas the c&l unit is a visible tube inside the meter. hope that helps.
