My lancer is running a g4+ atom. I have a air temp sensor from a commodore and a map sensor from a celica or something similar. Fairly easy to find at pick a part. Managed to tune it myself with guidance from @Roman, I shoyld probably pay a visit to @kpr at some point
From memory, they have a proportioning valve thing in the back that works off suspension height. My brother had issues on his l200 when it got slammed into the weeds. There is a length part of the lever needs to be at ride height
Giz. Currently attempting to build something similar. I work for a place that services/fixes disability equipment so I have 3 scooter chassis to chop up
