Question about C&L Mass Air Meter

[TenorPlayinGuy]

I have a 76mm Unit working on my car. However, I had done some things over a year ago before I put the car away for a long nap. Now I'm figuring out things that I did, that don't make sense in regards to a normal daily driver street car.

For instance. It looks like I put 42lb Injectors on the car!

Now I am trying to verify everything with my meter to make sure i have the right calibration tube. Their site indicates I need a green tube for these injectors, or code 104. Does this look green to you guys? or Blue? I know it's difficult to see.

It's hard to tell from just a picture(looks more blue that green, is aqua a choice lol) are there any stampings on the tube itself?

 

[TenorPlayinGuy]

i gotta go get a set of Tamper Torx bits to take the meter off. Then I can take the tube off and see if the number is stamped there.

Yeah, thats why I'm stuck. It looks aqua!

Best of luck! How does the car run and idle?

 

[TenorPlayinGuy]

Funny thing is, even with no real modifications, it runs just fine. Perhaps a little rich, but i've had it run REALLY rich before. I guess it's tuned ok. But I'm only thinking that I did this set for the Blower in my sig. Which means I better get a new 19lb Tube and set of Squirters.

This has gotta be costin me some mileage for sure.

Pulled the tube off, no markings to indicate what calibration it is. Guess I could email the photos to C&L to find out.

Anybody else wanna take a stab at the color?

Forget about telling the 'calibration' by looking at the color... they have been known to be mismarked...

Remove the sample tube from the housing, and measure the inlet & outlet of the sample tube.
Compare your numbers here...
C&L Sample Tube Information

Also, verify the computer catch code; A9L, A9P, X3Z, or ????
And, verify the part numbers on the sensor.

Let us know what you find...

 

[TenorPlayinGuy]

Computer = A9L
Meter = F1ZF

Measurements (Slightly Off for lack of my dial Caliper!)

Inlet = .65"
Outlet = .53"

I'm using a 1/32" Ruler and Eyeballing it. But that measurement doesn't match to ANYTHING that is on that forum.

What do you think? Should I just order a Calibration tube (104) and compare the two, if its different, use it, and if it isn't send it back?

 

[TenorPlayinGuy]

I found this as well.

Color code - Inlet Diameter - Outlet Diameter
Green ------- .6500" -------.4850"
Black --------.4880" -------.4880"
Red ----------.6570" -------.5125"
Purple --------.6500" -------.5400"
Blue ----------.6500" -------.5550"
Clear ---------.5650" -------.5650"
Orange -------.6500" -------.5700"

Looks Closer to the Blue unit now.

And if that's the case, I'm running 42# squirters with a 24# Meter!

HOLY RUSTED METAL BATMAN!

Meaning, I'm for sure dumping more fuel than the computer thinks.
