Are the maf tables for 02-04 LS1/LS6/trucks the same? I ordered a MAF for an 02-04 ZO6 and cannot Identify it with the part number stamped on the maf the dealer tells me it will work but... they also sent me 2 ford mafs first.....

 

Here's what I have collected for part numbers:

25318411 New truck MAF (& LS6?) and '01 Z06
This P/N is used on most every V8 from '99-'05
supersedes 25168491

Z06 MAF 25341604 - '02 85mm

F-body LS1 MAF 25179711

 

the # on the white tag on the maf is 25328057 the stamped in the plastic delphi # is 25168491 any ideas on the tables?

 

Yeah.. thats an 2001-2004 LS1 MAF or an 01 LS6 MAF with the screen. 02 + LS6 doesn't have the screen, but physically it's the same thing

Use the table info in here... http://www.ls1howto.com/index.php?article=25

You can run it with the screen or without... Just run the proper tables.

 

That MAF is an older truck MAF. I run it with the screen popped
out. This table has been good for me:

This is what it looks like. I cant rely on the number on the box, as you can see, this is the third different maf Ive recieved and each have been different. So back to my original question: are the maf tables for 02-04 the same for trucks/ls1/ls6? Also even though there are a million part numbers out there is the calibration the same for all of them? Thanks

 

Saw your post over on the corvetteforum as well..

You run the calibration for the vehicle you have (or the combo you use in our cases), The sensors are really the same. If you run it with no screen, then use the 02+ Z06 calibration table.

Truck table will be different due to the intake system being slightly different among other things.

I'm running that same MAF with NO screen in my 99 FRC with the 02+ Z06 cal table. ZERO issues. Buddy of mine is doing the same thing as well..
