S58 - CustomROM V1 BMW F97 F98 G80 G82 X3M X4M M3 M4 COMPETITION TUNE

• Can I get this if my DME is currently LOCKED and requires a FEMTO Unlock?

Yes. You need to purchase a BM3 license, activate your bootmod3 software license, and then send your DME to Femto. We provided Femto with means to load BM3 CustomROM software along with our Transmission Limiter Bypass. Once you get your DME back from Femto, it'll have the BM3 CustomROM on it with their unlock.

• Can I get this if my DME is Femto UNLOCKED?

Unfortunately, due to specifics around the Femto unlock, you will need to have your DME resent to Femto for CustomROM software to be applied along side their unlock. Your DME would lose its Femto unlock if we allowed a full flash of the software to be done. If you were to flash the MultiMap without resending it to Femto, you will simply have MultiMap's map1 power available and no CustomROM features.

• Can I get this if my DME is OBD or Bench unlocked (older X3M/X4M)?

Yes, flash away.

Anti-Lag

All new CustomROM tunes come with our fixed OTS Rolling Anti-Lag (13-14psi) at no charge. Fully customizable Anti-Lag is an available option for $200 and includes various tunable settings and safeties such as Anti-Lag Boost, AFR, min Accel Pedal required, Max. Time in Anti-lag mode, Engine Speed, Min and Max Temperature thresholds for Oil, Exhaust Gas Temps and others. **note all Map Switching slots 1-4 share the same Anti-Lag settings.

Map Switching

This is what to expect from Map Switching: Initially you’ll buy a new CustomROM tune from us,Paul and his team will work to dial the tune in on the mods and fuel type you choose.Next,you’ll have 3 additional optional slots, sold separately,to have variations of this map.

Some examples of great uses for map switching are to have street or drag map variation with torque by gear limitations for different tires or road surfaces, a kill map with higher boost/timing to be used on occasion,a daily map with reduced boost, valet, or flames map, etc.

Flex Fuel

A Flex Fuel tune will start off as a low ethanol pump gas or race gas tune and then dynamically adjust boost, timing, AFR, and fuel supply depending on how much ethanol content is added to the fuel tank. To allow for Flex Fuel tuning, an Ethanol (alcohol) fuel sensor and an Ethanol Content Analyzer (ECA) CANBus device need to be connected to the vehicle’s PT-CAN. To use Port Injection with a Flex Fuel tune, we recommend a PI controller such as the Motiv Reflex which adjusts the port injection output based on the ethanol content from the sensor.

**S58s require upgraded fuel system components that are sufficient to support the ethanol % that you intend to use with your Flex Fuel tune. (I.E. upgraded HPFP, LPFP, Port Injection, and or Methanol Injection).
