All sounds awesome. Glad I spent so much money to have 2 different people tune it... It doesn't matter to me which way it's done. I guess which ever way is easiest for you

1) Yes its in the supercharger. I did add the royal purple coolant additive (Purple Ice) to the supercharger cooling system yesterday - didn't really seem to do much but I only logged the one time...

its the 82716 file in the last post

I kinda noticed that. I said something to my wife about the fuel trims being all over the place (not that she knows what that was)

ok do I add 1.5 to all the values on that chart?

I don't have the OE GM (pre supercharger) tune on HPT. I have it saved from a Diablo tuner that I had and its in a .grg format... I don't have...

awesome... I added the ones that went missing and saved the file this time... Do I need to add(or remove) any others

todays logs

O yea I figured this wouldn't be a quick process!

Thanks Greg I will flash sometime this morning and go out driving and post logs when I get back

yes I made the changes last night then I loaded it this morning before going to work. I flashed then logged #1

Ok logged a few more times. I added misfire counters since it was asked about just to check but nothing showed and the car ran fine.

One of the issues with the car is shown on #1 at 7:13:19...

No I didn't feel any misfires.

schpenxel - what would need changed? I know the car still has the issue that it wants to stall on first start. It should be within the first minute of the log...

here is the log from this morning

Thank you. I know I'm prolly asking stupid questions but I like I said first post I'm new to this and just don't want to mess something up on my end. I changed the units for the MAF to match yours...

Thank You. So just copy paste this into the MAF Calibration Airflow vs Freq. correct? Is the way I'm logging ok or should I be doing something more specific when driving?

MAP installed & changed the 2 settings. Here is 3 logs - #6 is idling after the flash, #7 is just a short drive from work, # 8 is the drive home with one harder accel.

ok added Knock Retard and Idle Air Advance.

Is the Yes for the MAP or should I just leave that alone?

will do then I will log the drive home. Anything else to add?

What about changing the MAP like suggested before - do all I have to do is replace it then change the 2 numbers in the tune to...

Here are 2 logs from this morning. The First one (#4) is what the car does on cold start and wants to stall. The second one (#5) is the drive to work with a couple other channels added

Its not too bad but may need tweeked. I wouldn't say that it slams into gear but 1-2 can be a little harsh when cruising / driving normal

added cylinder airmass - what are the others that needed added?

Do I just change the Linear (312.50) and offset (-11.25) and I'm good to go for the MAP? If so then I will get the sensor coming...

Ok added MAF Freq. Will log when I drive to work in the am.

It is the older design - The heartbeat came out just after I bought mine.

I found the LSA/LS9 is a 3 bar # 12592525. What will I...

Thanks again - I posted in Gen 4

Story: Bought the magnacharger kit and didn't like the way the car ran and the way the transmission shifted so I paid for a remote tune from Pat G after borrowing HPT from a buddy. Through 8 tunes I...

That's why I'm here... I didn't think it was right and I wanted to see if I could get help to fix it... I had it in psi I honestly didn't think that it would be negative that much. I just...

I don't know what MAP sensor is in it other than I know its the stock LS3 MAP. I know that I asked the 2 guys that tuned the car previously (Pat G remotely and the local guy) about changing the MAP...

That's what I thought but its not reading right. I'm getting a -8psi at idle then goes down under throttle. Directions say pressure = (10xV) - 16. I have setup as (input/.1) + -16. Should be the...
