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 see this flow on your own projects before committing to a license.
FlowECU is aimed at professional tuners and workshops who want safer, repeatable results across multiple cars and ECU versions.
NZ customers: price is GST-inclusive.
International customers: treated as a GST-free export.
Yes. FlowECU expects map definitions from tools like WinOLS (CSV/A2L/JSON exports, map packs, etc.), or your own structured map data. It is not a replacement for WinOLS — it automates the tuning logic on top of those definitions.
No. FlowECU does not guess map locations. It uses the addresses and sizes from your map data. This is intentional: your existing definitions stay in control, and FlowECU focuses on safe, consistent value changes only.
Primarily for tuning shops and serious enthusiasts who regularly work on the same platforms and want to:
The current trial lets you evaluate FlowECU on your own projects. The paid license is aimed at professional use. Longer-term, a hobbyist tier may be considered if there is enough demand.
Because licensing is manual right now, please allow up to 24–48 hours after payment confirmation. Licenses are emailed from licensing@flowecu.co.nz.
