Correct... I suppose I should be more specific rather than encompass the details in "runs"

You need to add to your logs dynamic airflow, EQ commanded, vehicle speed, just to name a few. Your MAF and VVE need work and it idles rough because your timing goes from 25 degrees down to 4. As...

You won't hurt anything. It's just a preference as long as it runs/drives well

In the OS tab of your tune

Your trims are 20%+ rich in your idle and low RPM areas and at very low throttle inputs your commanding as low as .84 and not even close to being in boost? That's way too rich. Do you have a...

Without seeing a log you can try two things for now. First, put your timing tables back to stock and get rid of the "burble" tune. Second, go into Engine -> Fuel -> Oxygen Sensors -> and disable LTFT...

Log looks like the MAP if functioning as it should. I thought the DSX kits were PnP controlled? That would be cool if it's a CAN controller now

The top threads under each section of the forum are labeled "sticky" as they're usually important or FAQ's.

Negative. For a SD tune I would recommend using a custom OS. Either a SD specific one (if available) or use a 2 BAR OS scaled to 1 BAR values. They still reference the high octane table so it gives...

borrone, just remember with the MAF failed timing will reference the low octane table

Halfway there. Need a log still

I asked you to post a log on a thread you made 2 weeks ago with no response? At least you posted one in this thread.

I will take a look at your files when I'm at my laptop today but understand...

Post your tune and log. Read the sticky that tells you how to ask for help. I highly doubt your ECU is now enabling and disabling DFCO randomly after installing headers. There's another issue causing...

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
