RAL V2 · boost control & selectable cut
Standalone-style Rolling Anti-Lag control through the factory Evo X ECU. V2 extends the original RAL functionality, retaining its fuel, timing, activation gates and operating limits on supported ROMs.
- Boost targeting, progressive TPS taper & adjustable holdThrottle progressively reduces as boost approaches the target, then holds at a configurable TPS value to maintain boost, RPM and vehicle momentum. Reaching the boost target does not automatically stop RAL.
- Independent overboost protection & hysteresisBoost target control and the overboost kill are separate, with their own hysteresis. Target control manages boost around the requested value; the overboost threshold can disarm RAL.
- KnockSum protectionRAL can immediately disarm when the configured knock limit is exceeded. Existing RPM, TPS, speed, trigger and maximum-active-time limits remain part of the setup.
- Ignition cut, fuel cut, or bothSelect the cut strategy to suit the calibration: ignition only, fuel only, or combined ignition and fuel cut.
- Adjustable cut percentageControl cut density through the engine’s 720° four-stroke cycle, giving more control over the event’s aggressiveness than a simple on/off cut strategy.
- Normal throttle operation on releaseReleasing RAL returns throttle to normal driver control, including WOT when requested by the pedal.
Developed with repeated on-car testing and logging on an SST MR Evo X. The logic is not SST-specific; availability is confirmed against each supported Evo X model and exact ECU ROM.
Thresholds and cut settings are matched to your hardware and tune. These controls do not guarantee protection from engine or turbo damage. Motorsport/off-road use only.
RAL V2 is separate from the Tephra V3 upgrade.
RAL V2 tested on the SST MR Evo X
A huge thanks to Josh Burnard from Auto Torque – Performance Tuning for the extensive testing, logging and support throughout development.
In the development logs, TPS tapers as boost approaches a 16 PSI target while RAL remains active. At target, throttle holds at the configured value—approximately 65% TPS in this example—to maintain boost, RPM and momentum. Releasing RAL returns throttle to normal operation.
Boost-kill and knock-kill tests followed the commanded limits in the reported logs. These figures describe the tested setup; they are not universal calibration defaults.
Testing was performed on an SST MR Evo X. RAL V2 is designed for supported Evo X models and ROMs beyond SST, with exact-file compatibility checked before work.
You receive a patched ECU file and a TXT instruction file containing an XML snippet to add to your existing XML. RAL files may be BIN or SRF. Use the included definitions to tune and dial in the supported settings for your setup.
RAL + ignition cut + 5-bar patch
Combine your services into one order and one payment. Choose 5MT or SST ignition cut, add the AEM 5 Bar patch, and select RAL V2 if wanted.
One current ECU BIN covers RAL, 5MT or SST ignition cut, and the 5-bar patch. You can remove or add services before payment.
