Which bm3 map should I run??

[Roadrunner]

I have FBO and bm3 flex fuel kit, I was looking at the multimap stg 2 which has 4 maps
Map 1: ACN 91 octane
Map 2: 91 octane
Map 3: 93 octane
Map 4: stock

should I run this stg 2 multimap or should I just stick with the e50 map?

what octane is available in your area?

Multimap has flex on every slot. So if you have a flex fuel sensor connected properly, no matter the slot you are on, it will interpolate based on your ethanol %.

So… start with what your base fuel is. 91 or 93.

ACN is for crap 91 in Arizona/California/Nevada.

if you are running stage 2, you must have an upgraded downpipe
Running E50, you must have access to E85
With these two assumptions out of the way

If you want maximum power, run the specific maps, such as the E50 or E30 specific map. That gives you more power than the multimap.

If you want an easy solution and having the bm3 do the changes automatically, then run the multimap
