Welcome to efilive. Vehicle Interface. Engine. Transmission. Share. Knowledge is power

This web site has been created  to document and share experience using HP Tuners to remap a Vauxhall VXR8, which is a 2008 model with an LS3 and 6L80e automatic transmission.

Whilst personally I’m a computer professional - I have an unhealthy interest in automatic transmissions. I spent a few years learning how to make a 700R4 live behind a turbocharged 5.7 chevy in a heavy 4x4  - which gave me an appreciation of what goes on inside a transmission and therefore the modifications detailed on this site are not going for the neck snapping, tyre chirping performance that some people desire - as its my opinion that you are just abusing the mechanics of the box. So the changes I’ve made give a dramatic improvement whilst not being abusive to the drivetrain.

Whilst mapping engines is nothing new, the knowledge for the 6L80e automatic transmission is still being built up. I hope to use this site to try and bring that information together.

This site is non-commercial therefore there is no fear of upsetting any particular vendor, tuning shop or manufacturer. Users of other tuning tools (EFI Live etc) are more than welcome!
