Hellow All,
I just changed my tuning software to HP Tuner from LS2 Edit. I have a Supercharged C6 with N2O. We copied my tuning maps from LS2 Edit and installed it in a NEW ecm using HP Tuner. I'm having problems with the car throwing P0101 and P1514 codes. A friend wrote me the following email to try to help, but we can't seem to find these adjustment areas he suggests. I did check and my tuners version of HPT does not have the 2Bar upgrade, if this is what's holding us back I will buy it for him so we can get the car right. Any help would be GREATLY appreciated.
Thanks Jeremy

Good stuff, you swapped to HP Tuners.
Your PCM is constantly comparing the MAF airflow with that of the VE table calculated number. This is to check the MAF operation. For FI cars this can cause an issue because the VE table only runs to about 21 psi (105Kpa).
To fix this you can increase the Maximum Delta Airflow - P0101 Error table so that the airflow delta between what the MAF is reporting and the VE table is calculating can be larger and hence P0101 will not be set.
Go to: General Tabs/ Engine Diagnostics Sec./ Maximum Delta Air Flow; double the value or multiple the table by 2.
Are you still having issues with the "reduce engine power" - P1514 Error; double that value as well.
