Yes, now I just need to upgrade to MPVI2

Since you loaded stock tune and had no change, have you checked for vacuum leaks?

Gas (Gear): This table is used to determine the commanded open loop equivalence ratio when running on gasoline and the transmission is in gear.

This is not where you want to add fuel. You set your...

Had the same issue today on a 2002 Truck running the latest beta.

What MAP sensor are you using?

Tried using serial output today on the AEM 30-0300. I was able to get it to display but the AFR is being rounded off.

Start with the idle base & coastdown spark, that is not a huge cam and should not be that high.

Interesting......

You have not properly failed the MAF in the tune and why would you zero out the Airflow Vs Frequency table.

Cylinder Volume changed for bigger motor which bumped the VE table up.
EGR disabled.
Idle speed bump to 940.
Flow Rate Vs KPA changed for bigger injectors.
High and low octane table bumped up....

Sorry, thought you had messed with the electronic throttle table by the way you worded your post. Now I realize you modified Part Throttle Shift> Throttle Position% in Trans table.

Holy crap! Didn't even look at his timing tables!

Yes, his VE table is way low. He will need to copy in his stock table and re-tune.

The MAF is not turned off in your tune. What have you changed under electronic throttle as those tables can cause some serious issues when modified. I would put them back to stock and reset your...

Post your tune so we can see what all is turned off in it.

Did you put these tables back to stock value?

Closed Loop Enable> ECT vs IAT
LTFT Enable> Min ECT & Max ECT

What is your fuel cut off RPM set at? Right at 7000 RPM it looks like its cutting fuel then kicks back in under 7000.

Just looked at my old G8 Stock Tune. You can change the transmission type to manual, and it also has a manual tab. Will this not work for your application?

Google J1962 pin out.

Pin 6 is CAN high, third pin to the left from top right.
Pin 14 is CAN low, third pin to the left from bottom right.

Check continuity between female end of OBD 2 pass...

I would also log injector duty cycle.

Your problem is the MAF and VE tables are still stock.

You need to call or email FIC and get your injector data. Do you have any data for the MAP sensor, readings at 0 and 5 volts?

Only injector changes I see is the "injector offset" has been changed...

First thing you need to do is make sure your injector data is correct. Are you running a boost referenced fuel pressure regulator?
