Open loop its at -0.25 LTFT going WOT. I did 3rd gear at 2500 rpms for about 5 to 10 secs before I went WOT to 7200 RPMS to stop logging. 4th gear seems slow to do it at 2500 rpm. If anyone wants to correct me feel free to do so.

the VGI maf scaling utility needs 3 full throttle runs from 2000-redline preferably 3rd gear but 2nd will do if no safe place for 3rd, this is for open loop scaling.
For closed loop you need about 15 minutes or more of cruising , steady or light slow throttle movement driving at varing speeds and rpm. You can do some light steady throttle runs up the rpm range to about 5000 to help get some closed loop info at the higher rpm
their is more help in the vgi utility. linked in first post
