Hi, my car is tuned in AFR, if I wanted to change this to Lambda without re-tuning it is it just a matter of converting the target AFR table figures to lambda as discussed in the video? Is there anything else that would need to be changed as well?


It all depends on the software / ECU you are using. Some allow you to select AFR or Lambda and will display the selected units. Why don't you provide some more information on what ECU and software you are using?

I was thinking more in general but i'm running a link G4, PClink version

G'day Julian.

I'm pretty sure PCLink is stuck with using AFR as the unit, you can change it in PCLink+, but you obviously need a G4+ ECU for that to work.
