I have the chance to get a 73mm MAF for $125. Is that a good deal? And will it be OK to put in my 3.8 N/A when it came from an SC? I don't remember if the injectors were different or not.

Since the guy is also selling his SC, he would need mine back so if I need a chip to make it run right, I'll haveta wait until I can afford the MAF, the other mods I would do, plus the chip. Just making sure that I won't hurt my 'Bird when I'm trying to help it.

Don't waste your money...

Melon,

The C&L meter rapes the signal going to the EEC and makes it think the engine is under a different load than it really is. That usually shifts the A/F ratio to the lean side. It's a garbage meter, but some swear by it. I used it myself for a few years, but I learned.

Save your money for something else.

Thanks - I'll save my money for now and find something that will help me out.

The wrong way to go is: For exampe add 30# injectors to a 4.6 V8 and just change sample tube and lie to the EEC.

If you have #19 injectors (4.6 V8) and add a 73mm C&L and use the silver tube (#19)then you have a MAF with the closest transfer function of any MAF on the market because it uses the stock Ford electronics. To use bigger injectors the best way is with a chip or EEC tuner.


Nothing wrong with C&L. It's in how you use them.

Read this FAQ by Dr. Fred


Mass Air Meter and Injector Considerations on an SC

E-mail Dr. Fred he knows this stuff backwards and forwards.

A-Train and Seabass know their stuff, but in this case aren't considering all the facts.

If the 73mm came from a 3.8 SC engine and it had the stock injectors, then it has a silver sample tube.

Call C&L and ask them what sample tube could be used on a N/A 3.8 V6. Even the 302 V8 (#19 injectors) uses the silver sample tube. I wouldn't be suprised if the silver tube would work for you. I suspect that the transfer function is simular between Ford MAFs and only the EECs are different.


One last thing, people get around $100 $125for a used 73mm C&L on corral.net and ebay so if you pay $125 and it doesn't work out or even if it does you can try it for around $25.

Oh how I wish this was...

The other Jerry.

Jerrytbirdsc, you need to learn how things work before you make a post like that. The C&L meter rapes the signal and without the proper transfer function, the EEC is being lied to. Never lie to the EEC.

You know what I found with MY 4.6L supercharged engine. With a stock 70mm MAF I was pegging the meter by 4,400 rpm. With a C&L 73mm MAF I was pegging the meter at 4,000 rpm. That means my injectors went sonic even earlier.

Are you trying to say you were running stock injectors with a sc engine? I doubt you were. I told the guy to call C & L.

His first question was if $125 was a good price. My first post was in response.

Why do you have to take these personal shots at me. You don't know me at all.

Please explain why a 73mm C & L setup for stock injectors and stock EEC program would have the transfer off? Are you trying to tell me a C & L meter setup for a 4.6 V8s stock injectors and a stock EEC program would not work and peg the meter?

I never told the guy to use larger injectors and sample tube. Sounds to me like you were trying to use larger injectors and just a sample tube to compensate. You have learned that isn't the way to go and you are correct.


I just fail to see how running stock injectors, stock MAF electronics, and stock EEC program with a 73mm C & L would not work correctly. It may be that C& L don't have a sample tube for a 3.8 N/A, but I'm sure we could find out.

What is the way to go for a MAF then?

Okay, I thought C&L was okay ( I haven't used one just what I read. ) What is a good MAF to use. I'm getting closer to wanting to mod it and I'm still not sure which to get the Pro-M or the C&L... Perhaps there is another one that works better. I am gonna use stock injectors (19# I think...).

If you have a stock 70mm Ford MAF then you are in pretty good shape. I am not sure the throttle body size on your 302, but I am thinking it's not bigger than 70mm and probably around 65mm. On my 89 SC for example, only had a 55mm MAF and a 63mm throttle body so the MAF was a restriction.

Unless you are going to upgrade the throttle body the MAF will not be a restriction. Don't look for a MAF to be a big power adder on stock injector and throttle body setups. I think you will be fine with a C & L or Pro-M if you think you need something bigger than a Ford 70mm. A lightning 80 or 90 mm are also very nice but REQUIRE a custom CHIP or EEC TUNER and a wire harness adaptor to work on your T-Bird.

Fred Holzhauer a.k.a. Dr. Fred used a 73mm C& L along with a 75mm TB and was very pleased with it. This guy knows how to write a EEC tuner file.

i thought the whole thing w/ the C&L mafs is that they dont need a chip.... am i wrong? i had one on my 90 sc it seemed to work well, anyone put one on a 94/95 SC? (im pretty sure the stock is 70mm on those) any good/bad experiences w/ the 73mm C&L maf on the later SCs?

Fella's...I knida disagree with the C&L discussion. My Bird runs great withthe stock electronics and the 73mmC&L unit. I do have a chip and a decent program. By the way, I need a little help withthe terminology. "Pegging the meter" means what and "sonic" injectors. Help me out. I am getting older with this engine stuff but that is new to me. Also, Dan told me that there is no need to increase injectors unless you are SC. My two cents but I would love those definitions. Thanks.
