1999 camaro ls1 to ls3 need for bin or cal file

Hi
We have make engine swap from LS1 to LS3 to 1999 Chevrolet Camaro. We use throttle cable, not electric.. we use orginal PCM and need is for new bin och cal file.
LS3 engine is LS376/480 from GM performance parts.
Transmission is auto
Rear End Gear Ratio: 3,55
Current Tire Size: 275x40x18
Anyone ?

If the new ls3 engine has 58x reluctor wheel you will defenitely need the newer design pcm to run the engine.
This engine has upgraded hot cam so stock calibration is not an option for you.
Auto transmission makes it even more complicated.
You will need custom tune either way.
