C&L MAF from a 4.0 SOHC on a 5.0?

[celly]

I just scored a '99 Eddie Bauer with the 302 in it. I traded in my Sport with 4.0 SOHC in it, so obviously a lot of parts won't swap over to the new engine. I was wondering if anyone who know if I could use for C&L MAF that I used on the 4.0 on the 5.0. Keep in mind that the C&L isn't a MAF itself, but just a larger body. It doesn't have it's own electronics, and uses the stock guts (you unscrew it from your OEM MAS and insert it into the C&L).

I asked Doug Studdard of Bamachips what to do. He told me he's never tested this particular part on the 5.0 so he couldn't say with certainty if it would work or not (I appreciate his conservative approach). In fact, he got a bit more technical:

"I wouldn't swap it onto it unless you had some sort of wideband 02 sensor setup you could keep track of the a/f with. You could be running too lean with it."

I'm a mental midget when it comes to technical issues involving the engine, so I'm not really sure what that means.

Has anyone actually done something similar with their 302 and got it to work safely? The C&L MAF body is larger than stock, but not by a huge amount. I had the C&L on their briefly last night and it ran fine and smooth as silk. I don't want to cause any longer term issues so I promptly took it off this morning. I'd appreciate other people's input who may have some a similar swap or have ideas on how to make it work. Otherwise, the C&L is up for sale soon. I'd rather not part with it. The addition of this MAF to my SOHC made a subtle difference and I wouldn't mind something similar on the V8.

TIA

Is it the 73mm or 77mm housing?

All you would have to do is change to the correct color sample tube to make it compatible with your 5.0. Most likely they are the same but you should call C&L to confirm.

It's the 73 mm one. It doesn't have a sample tube. I remember Doug telling me explicitly that these ones don't have them. Here's Aldive's thread with pics. Mine is identical except I painted it.

I'd think you would be fine then. The C&L's for the stangs just use sample tubes to change injector sizes/applications with the housing staying the same.

I actually held up the C&L MAF to the OEM one and the diameter and volume of the MAF bodies are almost identical. Given that I'm just using the stock electronics, my way of thinking is that I'm not really changing much.

The OE maf on the 5.0 was 70mm stock, so your gaining 3mm.... not worth it IMO.

It just fits my intake setup better. I'm using the stock tube, but I had the MAF running into my Volant box. I can do it with the OEM MAF, but need to fab it up a bit differently. I'm not worried about the performance "gains", but don't want to hurt anything either by going with the C&L.

Here's a pic of my old setup:

Right now I've got the Volant box in the same place on my 5.0, I put the C&L in place, but I've got the stock tube from the V8 going into the box now. To go with OEM, I need to add the MAF adapter from my Volant kit which is doable, but I'd prefer to stick with the C&L, "just because"

I'd run it, the long term fuel trims will dial out any differences in air/fuel anyway, so if it's *slightly* off you'll be just fine. The ford PCM's are pretty adaptive.

Thanks for the info. I'm going to give it a try a bit longer. I haven't noticed any adverse effects at all.

Cheers!

A 73mm does have a sample tube this is how C&L adjust for the different sizes injectors you use. I have used 73mm and have a 76mm (I don't currently use but is set-up for 19# inj naturally aspirated). Call Lee @ 1-256-882-6813 if you cant get a hold of them they always call back so leave a message.. Lee will confirm that his 73 does have a sample tube. If you look on his website you will see that he offers sample tubes for the 73's.

Thanks for the insight. According to Doug (bamachips), the sampling tube design was an older one. The one that I purchased (and the same one Aldive has) don't have sample tubes in them.

On the new style meters they don't have a sample tube (such as a 05 Mustang or a new gen explorer after 03,or F150 04 or newer with the "credit card style meter") But all Mustangs to 04 the C&L will come with a sample tube, All Explorer to 03 will use a sample tube if it uses the small hole in the meter (1/2" diameter)..so on and so on...

Here is a quick way to know whether or not you will need a sample tube. If your meter has a rectangular slot to slide electronics into you will not need a sample tube (new style meter- 04 new Exp,05 newer Mustang, 04 newer f150

If your meter has a small round hole in it (1/2" diameter) you will need a sample tube. (All years before the ones stated above.) Old style..

There is one exception an that is the lightning meter or lightning style meter which is somewhat in between the new and old meters. The meter will have a larger hole in it and will accomodate the electronics for the lightning or "large hole" electronics. The lightning meter is a lot larger than the Expl meter. And the electronics design look similar to the "credit card" or rectangular style new meters.

James:

Thanks for the info. I'm not sure what all that means. I'm just going on what Doug told me.

 

[jah81592]

No prob. The old style with the small hole (1/2" diameter) will need a sample tube. The Lightning style will not need one. So if I get my head out of my ass and remember that if your 99 had a composite (plastic) meter with a big hole in it (larger than 1/2" diameter) you will not need a tube. Sorry for the original incorrect post but this is a product of a lot of changes with Ford in a few short years. I hope they stay with this one a while.. I edited my previous post and it will explain the differences in the meters and which ones need tubes.
