Leonardo LPG ECU programming
These are the screen captures from the ECU program on my car, descriptions follow --

main menu, what you are greeted with when you first open it

Menu option 2 - vehicle configuration screen (6 cylinder, 1100rpm changeover, changeover by rpm and 0.5s overlap are the changes that I've made from the defaults)

Menu option 3 - optional configurations, tab 1. Set the over-rev option here if you want it to go back to petrol at 5k ish, that keeps full power all the way to the rev limiter (LPG tends to die off about 5.5k usually)

Menu option 3 - optional configurations, tab 4. cut-off option, saves gas on the over-run. I've chosen 1/2 the default setting, which will be dependent on individual setups anyway.

Menu option 1 - the display parameters screen, shows all the settings as the engine is running. You can check the rpm, throttle position and lambda signal running on petrol before switching it to gas. Once it's gassing then you can see the ECU move the actuator around too, and the red and blue bars appear once it's learned the range to operate within.
The important thing is that when you change any of the numeric values you have to press return afterwards, or it doesn't remember the change. That's the only peculiarity that I've found ..
