Hi all.

Can anyone help with the Renntech tuning box settings. I recently upgraded to a facelift model.

The boxes are apparently the same but they have to be run on different settings for the facelift.

I can only find settings for the pre facelift. Does anyone have the settings for the facelift.

Thank you in advance.

Not so sure abt the above.. I remember that 6-9 is for 100++ octane and racing fuels, whereas 4-6 for 95-99 and 1-3 for lower grade fuels
