I got the DVD tuning kit from Calibration Success and I'm trying to do a MAF calibration to my LS2, I followed the DVD tutorials and everything worked out great and learned a ton of things about tuning PCMs, but as soon as I connect the laptop to the PCM , both the commanded lamba and lambda error PIDs and the MAF X Lambda error and the MAP X RPM historgrams disappear and a "Unsupported Parameters" is written on the table. I re did everything a few times just to make sure of all of the equations but I still got the same problem!, I started hating that thing and wish I just could get back to carbs and distributors and points!!, here is a copy of my CFG file and I wish one of you guys could check it out for me please.

First get the cable to check valid PIDs, which it usually
does when you hook it to a new vehicle. I don't know
if there's an explicit way to force it. But anyway, first
you need to have the right PID set understood. Then,
you should reconstruct all of those custom PIDs and
histos. If you went and edited those up in advance,
against a default or wrong-vehicle PID set (like, maybe
the instructions are for a LS1 and maybe there is some
difference somewhere) then learning the new base PIDs
might just rip up your work, like you see.

Might have to go and check PID by PID looking for cases
where your LS2 selections, maybe don't match (either
name or number) what you're working from.

There's probably folks with more experience at the custom
PID stuff, over on the hptuners forum.

will open your config later and look but you have something set up wrong. I was battling the same and found out that I was digit off one time, another time it was my commanded lambda was wrong ( I believe e40 1/EQ), you also need to make sure you have anything right in the display table....do you have A/F high res in there?

It just turned out to be that I didn't add the "Air Fuel Ratio Commanded hi res" in my primary table, I just added it and everything thing is working just fine.

Tonight I will try to calibrate the MAF, I'm so newbie in tuning but will see what the results might be.

Thanks guys for all the info!
