Accessport Map Refresh
Re-issuing or adjusting the map on a car we already tuned — same turbo, injectors, fuel system, intake and exhaust. AP reset, a driveability tweak, or a different octane on the same setup. Changed the hardware? That’s a full Custom E-Tune, not this.

How Tuning With M-Tuned Works

You're not buying a file and getting left alone. Here's the whole process.

1

You order, I build your base map

Tell me the car and what's on it. I write the first calibration for your setup — normally within 24 business hours — and load it into your portal. You get an email the moment it's there.

2

You flash it and drive

Every tune arrives with step-by-step instructions written for your car — how to load it, what to set up, and the exact RPM and gear for your pull. The portal shows the parameter list for your platform too. First time on an Accessport is fine; you'll be told every button to press.

3

You upload the log, I read it

Drop the CSV in the portal. It runs a virtual dyno on the pull and a tune health check automatically, so you see the power and how the engine behaved before I've even opened it. Then I go through the log properly.

4

I revise, you repeat

A revised map appears in your portal with notes on what changed, and instructions for the next log. A car that behaves takes 3–5 rounds, about two weeks start to finish — Mike replies to each log within 24 business hours, the rest is your driving time. A stubborn setup can run to 20 rounds; that comes from the car, never from waiting on a reply. Every tune has up to two months from the day it starts. You can watch the power build across every revision in one chart.

Your portal, not an inbox

Every log, every map and every message in one place, tied to your order. Download any tune again whenever you want, see whether I'm open before you ask, and message me directly in the thread. Nothing gets lost halfway down an email chain.

The log list is built in

The parameters you need to log live in the portal, picked for the car on your order — one tap above the upload box. Nothing to hunt down on a forum, and nothing to lose track of if your Accessport gets reset.

Tuned to stay alive

Every map is written to a set boost target, and you're told the number to abort at before you ever make a pull. Anything odd — a rough idle, fuel trims out of range, boost past target — and the instruction is to stop and send the log, not push on. Power is easy; keeping the engine is the job.

Talk to me before you buy

Not sure which tune you need, or whether your setup is supported? Message me on WhatsApp — the green button on this page — and ask. I'd rather answer first than sell you the wrong thing.

Conservative Tuning Safety-first calibration

† About lifetime support: it covers the car as it was tuned — questions, logs, and help with the calibration you were delivered, for as long as you own it. Change the hardware after delivery (new turbo, injectors, fuel system, intake, etc.) and the map no longer matches the engine, so it becomes new calibration work — that’s a fresh Custom E-Tune above, at the normal price. The Accessport Map Refresh is only for a car whose hardware hasn’t changed.
