Jb4 map suggestions
So I installed my jb4 on my 19' M240. I'm running a dinan mid pipe and a dinan intake. According to the map guide It appears I can run Map 3? I run only 93 octane. I was also curious about Map 5. Any advantage of running either or? I figured certain maps would require certain mods but it doesn't really specify on their site, just what psi over stock it runs.

That's why I listed I have a b58. You have/had an N54/55 and this is map 5 for you guys "Map 5: Autotuning. Adjusts boost curve from 11psi peak to 16psi peak based on octane, mods, climate, etc. For those running E85 fuels up to a 40% mix can be used along with the flex fuel add on connector."
That's totally different than a map 5 for a B58. "Map5: Additive map with peak of 6psi over stock added & intake temperature signal spoofed lower to increase timing advance" |

What firmware are we talking about here? I'm not sure what I should be running on my 18' 240i with BMS CAI and VRSF ctles DP running 93 octane. It's been hit and miss with Map 2/3 on performance. Would map 5 benefit?
