Post a log of the issue if you have one. A tune file by itself won't help much.
What engine? Mods? Fuel system? Gotta help us a little here
I have my doubts but it's not going to hurt to try. Did you put it into MAF only or was that from Pat G?

Just go for a normal drive for 10 mins and throw one WOT run in there.
Sorry, meant to quote the OP's question in post 26.
I saw the changes. Would be nice to see another log though
That won't cause random KR
Yes the red label sensor was discontinued and replaced with the blue one. I'm just taking a shot in the dark here but your tune is in MAF only and your VVE table looks like it's been somewhat...
The fuel pump turning on when the door opens is normal but to have the map sensor read high enough to kick on your aux pump is strange for sure. Has it done this since you installed it? Assuming a...

If you posted your tune we could see if there are any issues. Your MAP settings should be as follows for an LS9 sensor.
linear 312.50
offset -11.25
Start by following instructions, like in the title of the sticky at the top of the page. If you want help post your tune and log
Looks like your MAF and VVE will need some work. Your also getting knock everywhere so you may want to make sure there's nothing causing false knock reading like your exhaust hitting the frame or...
Listen to Sirius, he nailed almost everything. ns158sl is also right. Tune in CL and put your MAF values back to stock but leave it disabled for now.
Only thing I noticed is your using the stock...
You won't hurt the injectors at 58 psi. Adjust your regulator to 58psi and copy/paste the 400kpa value in your injector flow rate vs press table to the whole thing to set yourself up for a return...
Nobody can help without posting a log. A complete list of mods would help too, seeming as your tune is labeled like you have a return style system but you didn't mention that anywhere
The FSCM can't be read by HP Tuners. The "read" file you see in the editor is just from their servers that will match your vin. If there's no parameters for the active exhaust there now then there...
Can't help unless you post a log
Your injector data is wrong, It's a matter of copy and paste from ID. Find your matching tables and input their values.
Your flow rate vs pressure is set at 36.9 lb/hr with 1300cc injectors?...
What injectors are you running? Compared to a stock file from the repository your injector data is wrong
Check your plugs and wires
radrace19, I found the software and cable for the trans. That should make life a whole lot easier. Thanks for the help!
I didn't know there should be a cable and software for the TCM. I'll have to take a look for it. That would be awesome if it's that simple.
Alvin, that's interesting that they don't work like a...
You already have a file to start, the stock one
Hey guys, I just got brought into a ground up build by a family member after realizing they're in over their head a bit. The build is a 1971 Blazer with a GMPP 427/570hp LS7 and a 6L80-E all...
Your tuner has you set up in MAF only but they cranked your VVE table up in your idle areas? Doesn't work like that. Also your long term fuel trims are adding 30% at idle and they don't see any...
