Ghidra Renesas Fundamental.
Read the algorithm. Not just the maps.
8 chapters. Firmware structure, Renesas assembly, registers, code flow, data tracking — taught on real Renesas ECU dumps from chapter one. Ghidra-only workflow. No IDA Pro license. No prior coding required. Final project: write a speed limiter from scratch — without touching a single map.
8 chapters. From opening a binary to writing your own code.
Every chapter on real Renesas RH850 / V850 firmware. No textbook examples. No simulated dumps.
Before you touch the ECU
Why reading code beats hunting maps when DAMOS runs out. The mental model that separates engineers from file flashers — and the community + safety setup before chapter 01.
Introduction to firmware analysis
Re-addressing rules, base registers r2 / r3 / r4 / r5 (sp / gp / tp / ep), memory layout of a Renesas ECU image. The orientation step every reverse engineer does before opening the disassembler.
Orientation in the disassembler
Listing, Graph, and Hex views. Navigation, bookmarks, function renaming. Direct copy / paste workflow between Ghidra and WinOLS — how the two tools talk to each other.
Firmware structure inside the disassembler
Functions, labels, cross-references. Improving disassembly quality on raw binaries — defining functions Ghidra missed, fixing wrong instruction boundaries, naming what matters.
Understanding code flow
Renesas RH850 assembly that matters: mov / movhi / ld.w / st.w / jarl / jr / jmp. Jump types, references (J / C / R / W), memory areas. Reading code flow like you read a map — by what it does, not what it says.
Registers — Renesas RH850 / V850 GPR file
r0 (hardwired zero), r1–r5 system registers (sp, gp, tp, ep), r6–r29 general use, r30 / r31 (lp link register). Function calling convention per Renesas ABI, where parameters live, how OEM firmware uses each register class. The architecture that decides what’s safe to change.
Firmware code reading practice
Conditional logic via jumps. Disabling a speed limiter without map changes — by writing your own code over the relevant function. The first time you make the ECU do what you want, not what the maps allow.
Preparing for certification
Final review and Renesas reverse engineering certification — 2-stage exam. Pass and your name appears on certifiedtuners.com — the public registry clients use to verify real reverse engineers.
The differentiator
The only structured Ghidra curriculum for ECU firmware. Not generic binary analysis. No IDA Pro license.
Every other reverse engineering course either teaches generic binary analysis (CTF malware, embedded games) or assumes you already have a paid IDA Pro license. This course is built entirely on Ghidra — free, open-source, NSA-developed — and every lesson works on real Renesas firmware. The tool cost is zero. The methodology is the part you pay for.
Everything to open any Renesas firmware.
- 8 chapters covering firmware structure, Renesas assembly, register architecture, code flow, and data tracking — in the order every reverse engineer learns them.
- Real Renesas RH850 and V850 firmware samples — no textbook examples. Every exercise on production ECU dumps you’ll see in client work.
- Ghidra-only workflow — no IDA Pro license needed. The tool is free; the methodology is what this course delivers.
- Pre-configured Ghidra project files — base registers set for each ECU type, so you start with the disassembler tuned to Renesas, not generic ARM.
- Direct copy / paste between Ghidra and WinOLS — the practical workflow that makes the two tools talk to each other on a real job.
- Renesas RE Certificate — verified on certifiedtuners.com, the public registry clients use to find real reverse engineers.
- Lifetime access + community support (Telegram + forum) + mentor feedback on chapter tests.

I expected infoscammers. Got genuinely useful content. Zero regrets. The quality is mega-pro.
Before you enroll
I’m not a programmer. Can I handle this?
This course doesn’t teach programming. It teaches you to read ECU logic using Ghidra as a tool. 80% follows a clear algorithm. If you can navigate WinOLS, you can learn Ghidra. No prior coding experience required.
Do I need Diesel or Gasoline Fundamental first?
Recommended but not required. Ghidra works at the firmware level — below maps. If you already calibrate in WinOLS and understand basic ECU structure, you can start here. If you’re completely new to ECU work, start with Diesel or Gasoline first.
Why Ghidra and not IDA Pro?
Ghidra is free, open-source, and developed by the NSA — fully featured for ECU firmware analysis. IDA Pro costs thousands of euros per year. This course uses Ghidra exclusively, so the tool cost is zero. The methodology is what the course teaches — Ghidra is the vehicle.
What ECUs does this course cover?
Renesas architecture: RH850, V850, SH-2A cores. Covers Japanese OEM passenger cars (Toyota, Honda, Nissan, Subaru, Mazda, Mitsubishi, Suzuki) plus motorcycles and power sports (Kawasaki, Yamaha, Honda bikes, Suzuki bikes). For Bosch TriCore ECUs (VAG, BMW, Mercedes, Stellantis diesel) see the TriCore track. For Continental / Delphi / Denso truck ECUs see the PowerPC track.
How long does it take?
About 5–6 weeks at ~1 hour per day across 8 chapters. Self-paced with lifetime access. Every chapter ends with hands-on practice on real Renesas firmware — not slides, not simulated dumps.
Two ways to go further.
Most Fundamental students take Practice too. Bundle now and save the upgrade later.
