Tuning a LS3 corvette

[johnnoumea]

Hi there,

I have to tune a 2009 Corvette c6 coupe , in new caledonia , and the ECM seems to be runing a european/japaneese tune. Just had a quick look in the file but couldn't see the main fuel table and i'm wondering if it isn't different definitions from USA files ?
This is not my first car tune but this is my first american based tune and EFI live tune. ( experience on motec / autronic / qflash / qedit / nistune / hondata / AEM ...)
Anyone can help me on this ?

Thanks in advance,

Can you post the calibration file you read from the Vette...

Its a regular US factory 09 C6 M6 tune :).

There is no main fuel table. GM has been running a "virtual" VE (airflow model = "fueling" table) table since 06. VVE tables run a set of complex coefficients to generate a virtual VE surface that the ECM calculates on the fly.

Search on virtual VE or VVE tuning tutorial by Swingtan and that'll run you through getting it tuned if you want to get into the fueling that deep, but it depends whether you are aiming for an SD tune or want to stick with closed loop running on a MAF and simply do PE for WOT fueling.

Cheers :).
