Fuel map after scaling
SO I just finished scaling my 1200cc's for e70 and I got my LTFT mid down to 1.152 or something(going off memory) and I noticed something that I think is very strange with my fuel map.
Everything I know about tuning AFR from this forum is that the numbers in the Fuel map are just reference points and will not be exact but my fuel map is easily within 3% of being exactly spot on. I enter 11.8 in the map and I get 11.8 in my log. This is happening all accross the map .
My question is should I be afraid or is this ok?

Oh yeah definitely. No more lean spool for now but I may re-enable it with tweaked settings once I'm done fine tuning.
I've messed with it more and it's pretty ridiculous. I just enter what AFR I want wherever I want it and then there it is in the log and I also try to watch it on my LC1. It's on at night within 2-3% but it's slightly rich during the day.

Do you think the variance between day and night has to do with temperature possibly? My IX has 108k miles on it and it still runs great but sometimes it does some weird stuff so I'm thinking about replacing the ECU temperature sensor just so I know its working properly. So many maps and algorithms are based off of that temperature sensor so it couldn't hurt to have a nice new one jic.

I would imagine it does. I'm dealing with at least a 30* swing in temperature between night and day.
Also, my LTFT Mid is fully settled and is reading 0.39%. is this fairly normal? What are others seeing?
