So i've finally figured out how to reliably get the RX-8 to transition from closed loop to open loop, so i decided to finally make a Versatuner video that reviews all of the key tuning parameters that i feel are critical for rx8 performance and reliability. hopefully this helps people already using Versatuner and also encourages those who have NOT used ECU tuning software to give it a try by de-mystifying the concept.

UPDATE: In the video i promised to share the tuning files, so they are linked below. They are view only; you can probably download and edit on your end from a local copy.

By downloading and accessing the files linked below, I agree to only use the Versatuner tune file for personal educational purposes and will not install the tune file directly onto any vehicle. I understand that the MAS scaling and air fuel settings on this map may not be appropriate nor safe for my car. I understand that installing this tune on any vehicle other than the car on which it was developed may result in undesirable operation or potential damage to the vehicle. I understand there are no warranties or guarantees expressed or implied with this tune file and agree to download at my own risk.
