I want to use actual wideband vs command. So what am trying to do is create a separate pid to record actual afr vs command to get the afr error. How can I create a pid. And secondly how is math...

Read, read,read, that's all I can say, and get wideband it will make it so much easier to tune and plus you don't want to tune wot without one.
I did it like that and notice it was easier to tune since my afr don't jump around as much,

disconnected the battery, negative cable connected back and car started right up. :crazy:

One more question if u don't mind when making changes to maf or VE do I need to give it time for the new values to settle down,, like if I was tuning with fuel trim. Am tuning with a wideband.
