2017 F82, Full Akra with Akra Downpipes, JB4, E85

[NFAM3]

Hey guys. Still learning this platform. So I have a 2017 M4. I already have the full exhaust and downpipes with the JB4. I just put in 3 gallons of e85 and the rest 93. I'm still in map 2.

Questions:
1. Is my car making more power on map 2 with the e85 mix? Rather than on just straight 93?

2. Can I try another map? Or is another map better for e85 mix?

Yes the car is making more power with e85, and not to mention the benefits of running e85 (these engines really like e85)

You can try map 7, but some cars misfire/sputter on this map. If you expirence that just switch back to map 2. Map 7 though with 100 octane+ (MS109 or Gt260 Plus) runs amazing!

you can also slowly progress up to 4 gallons that will equal to an E30 Mix.

I mix 4-5 gallon E85 with 91. and run map 7

there is a value you need to change in JB4

Why not log it and see if its running good?

Honestly, bc I'd have no idea what I'm looking at. Just being honest. I did log a run today.

Here it is. Let me know if you want me to change or add values.

Post a csv of your log to the log sections on n54tech... not enough data here.
