Tactrix OpenPort 2.0

The CAN-capable cable for reading, writing, and logging Subaru WRX/STI ECUs. OpenPort 1.3 will not flash these cars.

EcuFlash

Read and write Subaru ROMs, and install the OpenPort drivers. Install this before plugging the cable in.

RomRaider

Open-source ROM editor and logger for Subaru. Pair it with current ECU and logger definitions before you change a cell.

RomRaider ECU definitions

XML map definitions that expose timing, fuel, and limiters in the editor. Load the pack that matches your ROM ID.

RomRaider logger definitions

Logger XML so you can pull IAM, knock, AF learning, and wideband alongside the stock sensors.

Learning View

Merchgod’s snapshot tool for IAM, learned knock correction, A/F learning tables, and DTCs: the closed-loop picture a log file alone will miss.

Hondata FlashPro

The Honda K-Series flashing and logging interface. Start here for hardware, supported ECUs, and software downloads.

Hondata FlashPro help

Official calibration notes, datalogging parameters, and feature guides so you are not guessing at a table’s units.

K20a.org

Long-running K-Series build and calibration discussions: engine combos, Hondata maps, and track setup.

LibreOffice Calc

Free spreadsheet for overlaying RomRaider CSV logs. You do not need Excel to read a knock count.

Innovate Motorsports

LC-series widebands that RomRaider can ingest directly. A calibrated AFR is not optional once you leave closed loop.

AEM Electronics UEGO

X-Series and older UEGO widebands, also supported in the RomRaider logger for Subaru work.

RomRaider forums

Definitions, Learning View, cable quirks, and Subaru open-source calibration threads.

NASIOC

North American Subaru Impreza Owners Club: engine management, hardware, and ROM ID confirmation.

Honda-Tech

The large Honda/Acura board. K-Series and FlashPro threads are scattered but deep when you find the right era.
