Is it possible to have the target lambda as a function of throttle position and RPM in the i2 software that I can use to compare against the actual logged lambda value?

Is there a reason you don't just log the target lambda channel?

What device is creating the log file?
If it's a dash, you could set up a 3D table to generate this channel if you aren't getting it from the ECU.

Hello David.

I have an older ecu (M48) in open loop. I don’t think it’s possible to log the target channel on the m48.

I have AIM dashes.

Regards.

It can be done in i2 Pro (but not in i2 Standard). In the maths window, go to create a 3d table, I'd think linear interpolation would work best. Screen shot below of a rough one I just tried.
