XDF for 2012 Chevy Cruze 1.4T (LUJ) - E78 ECM

Post by Hofty »

Hello everyone,

I'm hoping to get some help with my 2012 Chevrolet Cruze. I've been logging some data and I'm eager to give this little engine a bit more oomph, but I'm having trouble finding a compatible XDF file for my ECU.

I'm currently peaking out at about 16 psi of boost and my 0-100 km/hr runs are in the 11-12 second range. I know there's more potential in this 1.4L LUJ engine and I'm looking to learn and do some tuning with TunerPro.

Could anyone point me in the right direction for a bin definition file, or perhaps share a tune they've had success with?
Here are the specs from a recent GDS2 scan:

Vehicle Information

* Make: Chevrolet
* Model: Cruze
* Model Year: 2012
* Engine: 1.4L (LUJ)
* Transmission: Automatic
* Odometer: 191,049 km

Engine Control Module (ECM) Details
* End Model Part Number: 12647241
* Base Model Part Number: 12601244

Any help, advice, or files you could share would be greatly appreciated.

Thanks in advance!
