calibration tubes for C&L maf

[95riosnake]

I bought a C&L 80mm maf from a guy on corral, thing is, it's got the calibration tube for 42lb'ers. I looked on C&L's site and it doesn't list certain calibration tubes for the 80mm in a 94-95, only in the 87-93. I'm just need to know what color tube to buy for 30lb injectors. The wierd thing is, a certain color tube can be for different size injectors depending on what size maf it's being used in. I'm gonna call C&L monday but thought I'd check here in the meantime.

Thanks in advance for your help

I had a C&L tube for 30LB injectors but I cant for the life of me remember what color tube it was. They are not color matched to the injector size which sucks.

I've had to call C&L a few times off the number on their websites to do tuning for various cars, they are very helpful on the phone and can fax or email you the transfer (if they have it).

They offered to flow the meter etc for free if I sent it in.

When you call remember you have the 70mm sensor (Fox is 55mm).

My experience with tuning the C&L meters is that their transfer is not going to be perfectly on with the larger injectors, it will be best if you get a wideband and tune it in.

What do you mean by 70 and 55? this meter is 80mm...or is the 70 measuring something else about the unit? I was reading some in the link you provided and it says not only does the size of the meter change what tube is for what injector, but also what car (cobra or gt). I guess they will clear it all up when I call them

Well I just got off the phone with C&L and they couldn't help me. They claim they have never made an 80mm maf for a 94-95...so they can't tell me what tube to use. I don't know what year this maf was for, but I do know this guy had it on a 95 with a vortech, and it is supposedly set up for 42#. The guy from C&L recommended possibly going with a rich sampling tube and compensating for it with the tune, which is fine, although he couldn't tell em what tube to use. He said the right way to do it is get a 76mm but I don't feel like trying to sell this one and find a decent deal on a used 76mm. The budget is getting tight on this build and my wallet is burning so I'm about sick of spending.

Any help is appreciated.

I'm all for saving a buck, but a proper MAF is one thing you do want to do right because its readings dictate everything about the performance of your car. If you aren't getting it tuned then you need to get a better MAF meter, hands down.

Most of your dyno tuners will want to see the flowsheet for the MAF. If you don't have it (and they don't have it either) then they will either tell you to get a new MAF or charge you to dial in what you have (which by the time you pay the hourly fee/dyno time will cost about the same as a new one).

If you have a wideband and a way to log MAF voltage you can dial it in yourself but it is hardly something a beginner wants to do and I don't blame ya.

A better calibrated MAF will save you untold amount of headaches. I would go for the tune, however... on a modified car, that too is something I would consider a must-have if you want to keep it safe and get the most out of it with the fewest headaches.

The 70mm and 55mm: C&L requires that you reuse your stock electronics. They call Fox electronics "55mm" and SN95 electronics "70mm" - it is an important distinction because the sensors have a different air mass to voltage relationship.

I will be getting the car tuned, but if I can find a 76 I will go that route. The tough thing is finding a person selling a 76mm for a 94-95 (or are they the same maf for fox and 94-95, just with the different electronics from either bolted on?). Buying brand new is simply out of the question budget-wise.

Honestly I never really liked the C&L meters they are finicky. If I were in your shoes which Im not but I would sell the C&L and get a Pro-M (or what ever their new company is) or wait a little while and get one of those new digital mass air meters that are getting so much hype.

Yea I am gonna sell the 80mm either way, it sucks but oh well, I'm gonna ask what I paid shipped, it actually has been somewhat smoothed then painted with dupli-color 1200 degree primer, 500 degree silver, and 500 degree clear ceramic paint, so whoever gets it will get that work for free lol.

I think the new Pro-M is called PMAS, I always liked the C&L purely cuz I liked that they were aluminum instead of plastic, but at this point I just need it to work.

Yeah I know what you mean. I had the C&L ( I said 80 before But I think it was the 76MM) on my 95 GT and it just never did want to run right. I switched to a Pro-M 80MM and got a tune and it was night and day (yes the new company is called PMAS). Right now I run a Lightning 90MM meter but Im seriously considering getting one of the new digital meters when they come out if all the hype they have been getting turns out to be worth it since they are expensive.

 

[Stanger007]

That Lightning is a good meter. I just had to ditch mine because I was pegging it, but I've tuned several and they are always right on the money.

Are you talking about the ABACO meters that Anderson is pushing? I'm curious to see some reviews on them once they come out. I like that they sample the entire air stream but I still can't see how they perform better, save for physically flowing more air on the combos that need it.

They are pricey though, but at that level for the guys that need them, nothing is cheap.

So Wes, what is your experience with the PMAS meters, I know the company has changed, and they might not be the same as Pro-M. Any experience? How do they calibrate? Do you have to order them for a certain injector or do they have something that can be changed like the C&L units?
