Stinger/G70 3.3t ECU/TCU map (DIGITAL DOWNLOAD)

BMS ECU or TCU map for use with the EK1 flashing system.

We’ve migrated to the new EK1 map store: https://ek1tool.com/shop/tuning-maps?shopid=burgertuning

If you can’t find the BMS ECU or TCU map in the EK1 map store email [email protected] with your calibration ID, and the map you’re looking for, so we can add it for you!

NOTE: We only offer ECU/TCU maps for 2018-2023 models. We do not offer any 2024+ maps at this time.

BMS ECU back end flash maps:

We’ve got pretty solid JB4 back end flash maps developed now. Changes include revised air/fuel targets and scalar mapping for more consistent fueling, rescaling some annoyance limp mode limiters like turbine speed or boost too high, revised calculated torque for improved shifting, increasing shift timing for firmer shifts, and of course bumping up ignition advance for more power. With the BEF loaded you continue to use the JB4 maps as normal for determining how aggressive you want to run, boost by gear changes, etc. This gives you the best of both worlds. All the functionality and on the fly map changes a JB4 offers with the additional tuning tables a flash offers!

RACE: Ignition advance set to around 17 degrees peak, AFR around 11.9:1 at peak HP, suggested for those running good quality 93 octane up through 30% E85. Typically cars that are not running CPI.

RACE_IGN: Similar to RACE but ignition advance has been raised to 19 degrees peak, suitable for aggressive WMI applications running 93-E30.

E85 IGN19: Ignition advance set for around 19 degrees peak, AFR around 12.4:1 at peak HP, suggested for those running E40+. 40% E85 can be run on the factory hardware but for higher mixtures require CPI, WMI, or our HPFP.

All maps feature 9 degree minimum shift timing, and burble maps include exhaust burble in sport mode only. Note BMS complies with all emissions regulations and will not remove or disable any emissions equipment or monitor, so don’t bother asking.

BMS TCU Map:

Shift points optimized for tuned stock turbo performance (1-4 around 5900rpm, 5th around 6300rpm for 60-130 runs), shift pressures increased for quicker shifts and reduced transmission wear.

For models where applicable to launch use brake boost method: press brake down, press gas pedal to desired engine RPM/launch strength, release brake pedal, floor gas pedal. If this method won’t work on your calibration
