Instructions for using antilag can be found here: Using Antilag |
MG Flasher’s Antilag offers two modes: Stationary and Rolling. Antilag, also known as two-step or launch control, is a method used to temporarily increase acceleration performance (by increasing air pressure in your intake) during either a stationary or rolling launch. The side effect of using antilag (with ignition cut) may result in backfire (often a highly desired effect). The MG Flasher app provides simple and expert adjustable parameters for standing and rolling antilag. This will allow for an aggressive, flame-spitting two-step when parked followed by a safer, smoother rolling-launch (or vice versa) without having to reflash! Many safety parameters have been added to allow precise control over your car, including: min/max coolant temperature, max EGT, max IAT, max duration and a over-boost threshold. You can even decide the aggression of the torque limiter when these safety parameters are exceeded!

Where Custom Code v6.9 offers only Ignition Cut for, spitting flames, holding RPM, and building boost. We have released Custom Code v6.9.1 to introduce another method, Fuel Cut. The new method is significantly safer on your vehicle because it causes less stress. Fuel Cut will NOT spit flames! Users will be able to choose between the two methods. |
| Tip |
|---|
Works with automatic (ZF8 and others), manual,or DCT transmissions, in any gear, with any driving mode (eco, comfort, sport, etc.) at any speed. |
| Info |
|---|
Support Official support is currently only for F & G-Series Gen 1 B4x & B58. B4x engine support is per custom tuner request ONLY! |
Ignition cut is only available on the B58 platform. Ignition cut has been removed for OTS maps on the B4x platform (still available for custom tuners).

This will retard timing a significant amount and build a lot of intake and exhaust pressure. We recommend infrequent use of antilag and to obey all local laws. By using this feature, you acknowledge and accept the risks, including, but not limited to:

| Warning |

A catless downpipe is highly recommended to avoid clogging or damaging your vehicle. |

Safety shutdown (Emergency mode)
| Note |
|---|
If any of the safety parameters are exceeded, the antilag function will end early and require the user to release the throttle before resuming regular operations. Antilag will be disabled until the safety margins are within bounds again and the user releases the throttle. Emergency mode temporarily enables “Limp Mode” to reduce exhaust gas temperatures (EGT) and relieve boost pressure (opens electronic wastegate). |
You can log the parameter “Custom Code: Antilag Shutdown Reason”, or CC_ASR for short, to see the cause for the last shutdown event. Value resets to zero upon entering next antilag event.
Safety shutdown is engaged when:
Engine coolant temperature (Tmot) is out of bounds: “Coolant temperature min” (CC_ASR == 1) and “Coolant temperature max” (CC_ASR == 2).
Exhaust gas temperature (EGT) before turbo (Tabg_vl_xab) is greater than “Exhaust gas temperature max” (CC_ASR == 4).
Intake air temperature (tans_msg) is greater than “Intake air temperature max“ (CC_ASR == 8)
Intake manifold boost pressure (Ps) is greater than “Boost pressure setpoint” + “Over boost limiter“ (CC_ASR == 16)
Usage duration exceeds allowed amount (CC_ASR == 32)
Antilag Shutdown Reason, CC_ASR (Decimal) | Issue |
|---|---|
1 | Min coolant temperature exceeded |
2 | Max coolant temperature exceeded |
4 | Max exhaust gas temperature (EGT) exceeded |
8 | Max intake air temperature (IAT) exceeded |
16 | Max intake manifold boost pressure exceeded |
32 | Max duration exceeded (CC >v6.9.1 only!) |
Limitations
Antilag can only be achieved under the following conditions:
Car must be warmer than “Coolant temperature min“ to engage.
Must be within the “Safety shutdown” parameter bound.
