do you know how the car run with the BM3 stage 2 maps on E30?

I run Map 5 and use a blend of appx 5 gallons Costco 93 oct (has ethanol added) and appx 8 gallons e85 at Kwik Trip. I've tested the Kwik Trip e85 3 times and get an ethanol content of about 93%. I've been running this blend since about June 2017 and my car runs great. I am PWG.

I've run up to two gals of E85, which is about an E20 blend, on bm3 Stage 2 93 octane map and the car ran fine, logs looked beautiful. The E30 map has different fueling adjustments though so I wouldn't recommend going over E20 on the Stage 2 map unless you are PWG.

Is this 85% ethanol or 95%?

Looks like 85%

85% You read it at the separation line.

Thanks but where the water separates is at 95% that's why I asked

I have the same car as OP. I am running bootmod3 stage 1 93 tune. What happens when I put a gallon or 2 of e85 in tank then fill the rest up with e85? I have drop in air filter and cp. I felt like the car pulled harder but maybe it was placebo. I have not purchased the e30 tune because I am waiting to install my catless downpipe. When I put 1 gallon of e85 in the rest 93 on a 93 tune was it pointless or did raising the octane help even though it's a 93 tune?
