Default Help. first time mixing fuel with my JB4 (X3M40i) - 08-08-2020, 12:54 PM

I have a 2019 BMW X3 M40i with the JB4 tuner and drop in K&N air filter. I do NOT have a ******** yet. I usually run map 3.

This morning I put 4 gallons of E85 then topped it off with 14 gallons of 93. I also added 3 ounces of Lucas Safeguard Ethanol fuel conditioner. What would be the best MAP for me?

Do I need to go into any setting and make adjustments to anything?

Thanks Guys

Best to post some logs for review in the support log forum. Just put all mods and fuel running for them to review.
