I can tune the EFI differently to compensate? What would be an additive that you would recommend?

Thanks.
You are looking for a solution to a non-existing problem. An M117 Djet will run and be fine on regular gas with 5-10% ethanol. This based on 20+ years doing just that including 4-6 months of winter storage each year. Mixture specs have a wide range so no need to make any changes in tuning. Full time wideband AFR readout on my M117 shows no discernible difference when using 10% ethanol or ethanol free fuel. As posted before, spec for fuel hoses has changed to better handle ethanol and those should be upgraded all way from tank to injectors (and back)
