Anyone have it? Anyone have a write-up on a MAF calibration using hptuners?

 

I'm not 100% familiar with HPT's terminology, but the basic idea is to create a histogram, map, that mimics your MAF table. You then log the AFR error as your data parameter. Then use the AFR error to correct the MAF calibration.

The process is very similar to dialing in the VE table with the AFR error

 

if you have an actual LS6 MAF (compared to the SLP one where they add a resistor to trick the output)

I beleive you can use either the LS6 or the truck MAF tables (jimmyblue's posted about this before, he'll have a better idea which to use)

Hopefully someone that's done this can verify which tables to use as a starting point

 

I prefer the truck table as it indicates slightly more air,
making for a rich bias (but it comes out dead-nuts on
my F-body with descreened truck MAF). There are some
differences even between the trucks as well as the cars
that use the 85mm. I believe this is GM "fudging things"
for intake tract geometry /airflow bias effects.

Some of the MAF tables have kind of silly values, or none,
in the low range. Depending on your vehicle this could
screw up trims etc. (my A4 never gets below 2kHz but a
M6 with light accessory load, might). So this is another
criterion for selecting tables, simple "sanity".

This one is my fave:

PM me with your e-mail address and I'll send you:

IAC park position table
idle air table
idle speed table
MAF table

All the above from a 2002 LS6

 

is this a good maf table for stock o2 z28 with just lid....... is this a 5.3
chevy or gm truck table......

 

these tables are for the GM 85mm staff, won't work w/a stock MAF

 

I think you could find writeups on tuning the MAF table
but you really have to question why you're messing with
a factory trimmed air meter in the first place. There are
reasons but just feeling itchy isn't one of them.

 

Yes i know But i like to work with my car and learning more about it... It´s like therapi, a way to relax
