EFILive is pleased to announce the first PC based tuner for the E80 GM L4 SIDI Gas controller is now available in our August 27, 2015 Public Pre-Release software. This release commits key tuning parameters to deliver performance improvements, as well as a comprehensive scan tool to allow customers to monitor all essential tuning data.

This new ECM, released in-conjunction with GM's new range of L4 engines first appeared in selected vehicles in the 2015 model year release.  It is expected that this controller will continue to expand to additional vehicles in the 2016 model year and beyond.

This release delivers tuning support for North American, Europe, Asian and Chinese based vehicles all using the E80 controller.   A full list of currently supported vehicles can be found below, and on our GM Gas Supported Vehicles web page.


E80 tuning support is a FREE software update to all EFILive customers.  To access these features, customers must update their V8 and V7 software, along with their FlashScan V2/AutoCal firmware to our August 27, 2015 Public Pre-Release software (or later).
