Hey guys, I got a deal on a C&L 73mm MAF w/filter and Red injectors.

Previous owner put 25k miles on these parts and says they are 30lb injectors.

I have several basic questions..

1) Are these injectors really 30lbs and what is a reasonable way to clean them? (All the injectors measure 14.4 to 14.6 ohms )

2) Is this 73mm body truly calibrated for 30lb injectors? Meaning can I just plug and play with a stock ECU? (the MAF sensor has the same part number as my stock 1989 one. E9ZF-12B579-AA AFH55-03)

3) What is the small threaded rod for? (it has a roll pin pressed in the top which hits the MAF housing so it can't turn. It's a little loose and pokes through & into the wires air flow tube. (shade tree tuning?))

4) What power level is this good up to?

NOTE: I don't have tuning software yet so I can't tweak the MAF transfer function. I'll have my wideband installed before swapping these parts.








Thanks for the replies in advance!

1. Yes, they're 30lb injectors. Just Google " how to clean fuel injectors"
2. C&L mass air housings are junk. They use a flow tube to "calibrate" the mass air sensor. That is the reason you have a stock mass air on top.
3. That rod is there because Billy Bob lost the screw that really goes there.
4. Ditch the C&L. The fuel injectors are usually rated to about 430ish at the most N/A.

Are they junk because people don't normally change the MAF transfer function?

What was the screw for that Billy bob lost?

Most everyone, including me has had problems with them if they don't stay near a stock setup. That hole that the rod is in should have a screw there to hold the sample tube in.

OK thanks.

I don't like how close to the entrance of the tube the wires are. They ought to have made the tube & MAF position as close to OEM as is possible. Then tweaked the end diameter to get the A/F in line with the stock MAFTF.

btw, What tuning software do you use? I've only ever used SCT pro-racer for OBD2. Not sure what I should be looking at for this old stang. (I like to spray a dry shot and feed the fuel via larger injectors / pump)

I haven't used my tuning software yet because my project took a bad turn. So I've put it on the back burner for now. I have a MTX-L wideband and Moates Quarterhorse sitting in boxes though. My software is Binary Editor 2010 on my Netbook.

If you want to get rid of the Meter I might want to take it off your hands...PM me your price please

Alot of people on the net do say C&L is junk but I know people who swear by them and have never had an issue with them.

c and l meters often need to be clocked to be optimal

projectresto83

yes, yes they do. That trick also works with stock meters as well

HOW? can you elaborate?
