Motor is 98.
Which MAF do I get, F-body/vette/ or zo6.
(I am missing mine).

Convert it to a 85mm if you can program the Tables into that PCM.

 

Well if you dont convert to an 85mm, I think almost any maf off a gm v8 from 98-06? will work. I didnt have a maf for my 05 LS2 and it had the same part number as a ls1 maf.

 

They are different...look for a late model Truck, they have the same one.

 

i believe the older ones have the iat built into them 5 wire verse three in the newer ones

 

All the newer ones that I have seen are 5 Wire..

 

Someone has told me to use the zo6 MAF. I'm not sure how big it is (85mm?) but it will (should)work with some minor tuning. It should allow me to drive the car to get to the shop where the tuning will take place. I will need a adapter to change from my MAF 98 harness to the MAF ls6 harness. I think it just plugs in between the existing maf plug and the zo6 maf....?....

Does this sound right?

 

I saw the adapter because speed inc sells a LS6 MAF conversion. It comes with the harness and sensor and I hear the ls6 maf does require tuning on a LS1.

 

Oh yeah and also the LS6 maf is all plastic and has no screens. Another benefit over the aluminum ends as far as heat soak goes. I think that would be my choice.

 

^^That's the 85mm one..the Z06 MAF. The same one is used in the newer Trucks, the LS2 Vettes..

 

my 02 has only three as well as the slp 85mm i have, never looked before now, but my 05 truck has 5 wonder why they went back, oops, my bad

 

Here is a list of all the vehicles that use this MAF GM Part # 25318411 AC Delco 213-364 http://198.208.187.182/internet/Vehi...sel=A&pageno=0

Why don't you just run Speed Density?

 

If you purchase this MAF gm part # 25318411 how do you fit it on to an Fbody since the lid and bellows are only made for a 75mm MAF?

 

the bellows are rubber they stretch i got my stock one around a 94mm throttle body

 

And for the lid I guess I would need one of those TSP 85mm deals which, from what I understand, they don't make anymore. Is there another option?

 

i dont recall the stock set up but you can just use another piece of large rubber tubing i have two on mine one on both sides of the maf

 

So a new lid is not in order. Well now that I went to the SLP website and saw their installation instructions I see what you are talking about. The vision in my head has a "rigged" look with the hose on either side of the MAF. Are there two worm clamps used with the additional tubbing (one on the input of the MAF and one on the lid output?
