Dinan Stage 1 Performance Engine Software - 2015-2020 BMW M2C/M3/M4
Features:
- More Power: Max gains up to 146 HP / 155 lb-ft of torque over stock on the F87 M2C and 122 HP / 145 lb-ft of torque over stock on the F8x M3/M4 using E85. Consult the performance charts for detailed data and additional octanes.
- Dinan Stage 1 performance software includes a limited lifetime warranty against defects in the software and provides free updates and reflashes as they become available. Labor or shipping charges are not included in the warranty.
- Access to numerous octane callibrations depending on your needs (91, 93, 100, 104, and E85). Switching between mappings would require a reflash at a Dinan authorized dealer.
- The Dinan Heat Exchanger (D780-0001A) or equivalent is highly recommended when running ANY of the Stage 1 maps. Without it the vehicle will tend to heat soak / derate under any meaningful load. Advertised gains as a result will not be possible.
- Full map rescaling for drivability from idle to wide open throttle and everywhere in between
- Top speed governor removed
- Upgradeable from DINANTRONICS - See the Purchase Guide or FAQ linked below for details
- Retains all BMW factory engine damage safeguards
- Torque gains drastically improve acceleration
- No hesitation between shifts
- Downloads through the OBD2 Port - See compatability notice at the bottom of the product page
- Hassle free operation — Install and enjoy

COMPATABILITY NOTICE - BOX CODES & JUNE 2019 FACTORY UPDATE
DME box code and bootloader information must be obtained from the vehicle to determine if a vehicle is flashable in its current state. In some cases we will need to create a file for your vehicle. This process could take several days and multiple dealer visits.
Vehicles previously serviced or updated after June of 2019 may have received a DME bootloader update from BMW. This bootloader version will prevent the Dinan software upgrade from completing. DMEs with the updated bootloader must be removed from the vehicle, and sent to Dinan HQ to have the bootloader backdated. DMEs sent to Dinan for the backdating procedure will not be opened or physically modified in any way. Once the DME is returned to the dealer, they must still be flashed with the Dinan performance software through the OBDII port. If a previously backdated and flashed ECU is updated with the new bootloader, the above process will need to be repeated. Dinan will not pay labor under warranty to remove and reinstall ECUs that were previously backdated, and then updated by BMW or a third party.
