One clean patch center

ECU Custom Patches

Anti-Lag, BoostReady, GSI, and Live Tuning are now grouped into one EvoPro patch tab so customers can quickly compare what each patch does, what it costs, and what information must be sent after checkout.

Buy a patch Compare patches Prepare intake details

Pick the custom patch that matches the job.

Each patch has a different purpose. Anti-Lag is for controlled RPM-cut anti-lag behavior, BoostReady is for base-model turbo load handling, GSI is for ROM-side Gear Shift Indicator configuration alongside ETACS, and Live Tuning is for faster supported calibration workflow in EvoPro ROM Tool.

Anti-Lag Patch

Clean RPM-cut style anti-lag for supported Mitsubishi ROMs, delivered as a custom XML definition/service after the matching ROM is reviewed.

Cruise-cancel style activation workflow.
Custom XML definition prepared for the ROM submitted after purchase.
Designed for supported Evo X, Ralliart, Lancer, and Outlander ROMs.
Typical service window: 24–48 hours after ROM and proof of purchase are received.

Compatibility depends on exact ROM family, definition data, and safe flashing workflow.

BoostReady Patch

For turbo-converted Mitsubishi base model vehicles still using the original non-turbo ECU, where the calibration needs boost-aware load behavior.

MAP-based load calculation support for turbo-converted base model ECUs.
Referenced load-axis upgrade path for fuel, timing, VE, MIVEC, and cylinder fuel trim workflows.
Best for working vehicles with no current mechanical/electrical issues.
Optional XML axis/table upgrade when the existing XML was not built from real references.

Buy BoostReady Requirements

Not a substitute for proper tuning, safe logging, correct fueling, or a healthy mechanical setup.

$60 USD2008+ MitsubishiETACS + ROM

GSI Patch

Binary-level GSI / Gear Shift Indicator configuration for supported Mitsubishi markets where ETACS coding alone does not activate the display correctly.

ROM-side configuration for upshift gear indication support.
ETACS still needs to be enabled with MMCodingWriter or equivalent ETACS coding workflow.
Built for supported 2008+ Mitsubishi vehicles where the market was not originally configured for GSI.
Useful for fuel economy shift guidance, smoother driving, and added engine safety awareness.

Buy GSI MMCodingWriter

If ETACS-only coding works on your vehicle, you may not need the binary patch. If it does not work, the ROM must be configured directly.

Live Tuning Patch

Unlocks the supported live tuning workflow inside EvoPro ROM Tool so calibration changes can be tested faster before exporting the final live ROM.

Designed for EvoPro ROM Tool v4.00 and above.
Useful for table-by-table calibration workflow without constant shutdown/edit/flash cycles.
Requires correct ROM ID recognition, matching XML/definition data, and supported M32R kernel workflow.
Final tuned binary still needs to be saved/exported and flashed responsibly.

Buy Live Tuning View workflow

Live tuning access is not a standalone tuning program and does not replace calibration knowledge.

Same simple EvoPro flow.

The page keeps purchase, intake, manual review, and support follow-up clear for every custom patch.
