FlowECU sits beside your existing tools (WinOLS, map packs, CSV, BIN/HEX) and automates the boring, repetitive part — while keeping every change transparent and tied to real map data.
Windows only · Designed to work with WinOLS projects/map packs, CSV/A2L, and BIN/HEX files.
Keep using WinOLS (or your own definition workflow) to build map packs. FlowECU reads your map data (CSV/A2L/JSON etc.) and applies tuned values to the correct addresses in the BIN — no guessing, no auto-offset hunting.
Maps are grouped by role (boost target, lambda, torque limit, ignition, etc.) using a language-aware alias system. Different naming styles or languages can still be treated as the same role when you apply a stage preset.
Only maps that match known aliases are modified. Hardware/Software IDs are checked before patching so you don’t accidentally apply a tune to the wrong ECU. Anything that doesn’t match is left untouched and can be logged for review.
Apply Stage 1/2/3 presets or your own custom options for boost, torque, fuel, and timing. You choose the strategy; FlowECU does the repetitive math and keeps it consistent across files.
Every tune generates a human-readable change log grouped by map. Quickly review what changed, where it changed, and by how much — handy for shops, customers, or revisiting a file months later.
Trial gating, machine-bound yearly licenses, and straightforward inputs. No always-online requirement, no cloud lock-in. You keep using your flashing tools and workflow — FlowECU just takes care of the repetitive, error-prone parts.
An automation and safety layer for map-based tuning. It expects real map data from WinOLS/map packs/CSV and applies structured logic on top to make your stages and strategies repeatable.
It’s not a flash tool, not a 2D/3D editor like WinOLS, and it doesn’t auto-discover maps in a raw BIN. You still define the maps; FlowECU makes repeatable, safe changes across those maps.
The free trial lets you test this process on your own projects.
This video is a simple walkthrough showing the general FlowECU workflow — importing a BIN and map pack, applying a stage preset, generating a tuned file, and reviewing the change log. It’s not a sales video — just a transparent look at how it works.
