This is the way BMS puts it...
Maps:
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 30-40%.
Map 6: User defined boost map.
Map 7: Race gas map. 16.5psi on G4 board, 18psi on G5 board. Requires straight 100-104+ RM2 octane racing fuel.
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.
