Scott,

If you could get your hands on an LT1 MAF table, that would be very useful to guys that are looking for a MAF table that moves a lot of air. This is what I've heard, but I'm still looking for it.

This is only an issue on our fastest cars...

In these cases, we'll run a AFC and set it to whatever percentage of reduction is required to stay under 11,500 Hz. Then we'll change the fuel injector scaling in the PCM by that same percentage.

Question for the PROs.
What do you do when the big (V8) MAFs are outflowed (going over 11500 Hz)? :confused:
I had this problem for awhile and was frustrated. Solution was to run the SLP MAF from INTENSE, highest MAFF I've seen since the install was 10900. Well within the allowed table. It may take some PCM tweaking, but it works just fine now.
Oh... thats running a MP112 with a 2.7 pulley too :D

One more question for Scott. The tables you posted show only the flow numbers but not the coresponding frequencies. I suspect not all of these show flow at the same frequencies. How we deal with that?

Hey guys, I think I'm having trouble with my SLP/LS1 maff sensor. I do have the '98 Fbody LS1 maf tables in the pcm too. Have spoken with some knowledgeable people about this, and they think it's the maf sensor. I'm be cruising along say 55 mph and just randomly my LTFT's will go from around zero up to +16.4 and my AF (from my PLX 250 wideband) will show an AF of 10.0:1! So somehow the pcm is being commanded tons of fuel thinking it's lean when it's not, and my car drowns in fuel when this happens. Also get a "chugging" at idle just every so often when it's doing this. This all doesn't happen all the time, it's somewhat random but when it does it it always does it under gentle cruise. So......I have the choice of either running the 75mm maf sensor & matching maf tables that John T. is running (which I just hate the thought of going from 85mm to 75mm thinking it might restrict me some) or using an LQ4 maf. If I use the LQ4 maf, can anyone tell me if I use either the 5.3L or the 6.0L truck mafs on the first page of this thread?

If not, does anyone have the matching maf tables I could use with the LQ4 maf?

Thanks! :)

I would try and get an LQ4 MAF from the 6.0l truck and use the table from above. It seems that this is one of the easiest to tune setups.

So I've got an LQ4 maf sitting at the house, and I hear everyone for whatever reason just uses L67 maf tables and adjusts them a little for the LQ4 maf. Question is, is anyone using the 6.0L or 5.3L truck tables in their pcm with the LQ4 maf? Anyone? Just trying to figure out which tables to use in my pcm........

Thanks. :)

MAF Columns

Just picked up an 02 - 04 Vette MAF.

Problem.

99 GTP MAF has 4 fewer columns then the 02 - 04 Vette MAF.

GTP MAF is in 125Hz increments starting at 1500Hz to 11,500Hz
(80 Columns)

Vet MAF is in ???Hz increments starting at what Hz? and what is the highest Hz the sensor flows?

If the Vette MAF is also 1500 - 11,500 I imagin it moves in 120Hz increments?

Anyone know?

Thanks!
-Andy
