JB4+FMIC

[BMist371]

What map should I run for a JB4 2012 135i with an ER FMIC on 93? Map 5? What about FMIC and 100 oct? Most posts are about cars that already have downpipes and mine are still factory.

Map 5 ideal for everyday driving, but on race gas Map7 for sure depending on the octane you're running . Check the chart below

Map 0: Stock bypass. This is the only map you may use the OBDII diagnostic port with. Set to map 0 before dropping off for service, using a BT, etc.
Map 1: 13psi (suggested for most stock applications)
Map 2: 14.5psi (suggested for those with downpipes and 93 octane)
Map 3: Progressive meth mapping with flow sensor failsafe. See guide to enable. Meth use isn't supported/suggested without a flow sensor and map 3.
Map 4: Stock map w/ CAN active. Allows full logging and in dash gauges on the stock mapping.
Map 5: Autotuning map. Boost ranges between 12-17psi based on your cars octane, conditions, and modifications. Fully E85 compatible. If using E85 we suggest around 30% to start. Refer to the E85 FAQ for addl info.
Map 6: User defined map generally only used for diagnostics or troubleshooting.
Map 7: Race gas map. 18.5psi peak boost on the G5 ISO. Requires straight 100-104+ RM2 octane unleaded racing fuel. The expensive stuff. We do not suggest using leaded racing fuel. To use this map with E85 requires the BMS E85 back end flash, inline booster fuel pump, and a 60% E85 mix.
Map 8: Economy / Non-Turbo map. Triggers a 3100 "reduced power mode" code while active. After switching back to a normal map you will need to restart the car for the code to clear.

Leave it on map 5 in both cases

Thanks guys, just making sure map 5 was ok. I have been seeing some 15/16 psi spikes in this crazy cold air around NC mountains lately. Turbo heaven!
