@keithh2oskier @skiboyny @Windsurfnut I finally installed 9.2 and zbox but before I did, I noted @keithh2oskier's 12 on ball 1 setting, that really helped my SG 9.12.
I put in my 9.2s, auto calibrated, mapped, tested with no skier for timing, put in my old settings for normal 34.2 which are very close to Keith's and ran some passes without zbox engaged. Ran great so I put Zbox on B2 and it was even better, all times were tighter nothing greater than .02 variance and driver said he may have felt it was more consistent.
Not sure who it would apply to, but it really seems like boats with exact same engine configurations will have almost exact same settings, sure saved me some time and experimentation, thank you!
