Why get a Dirty Map?
Car remapping. Dynos are great tools for measuring power. But you need to invest huge sums of money to get results and data from them that correlate to every other part of the map which is not full throttle. And even then, do they really simulate your driving habits, your terrain, your altitude?
With our Dirty Maps we tailor your ECU maps for two key outcomes: maximum full-throttle power, as you would expect, and a tailored driving feel so your car performs everywhere in the rev range.
If you have seen our work online, you will have seen the benefits of proper tailoring — removing the OEM compromises designed for all markets, to make your car drive at its best.
How do we do it?
We take your list of mods and the real data off your car, and tune to actual airflow, your driving habits and your fuel grade.
We take real logs, from your real driving behaviour, to build a map that really performs. No off-the-shelf mapping. No one-size-fits-all.
Using our proprietary analysis software alongside the VersaTuner suite, we rapidly turn hours of data into human-readable output — so we can identify the ECU behaviours that are out of calibration.
What’s included or available in all tunes?
In all of our tunes, we can do the following. Most we do by default, others are optional. All can be chosen by yourself to be ‘on or off’.
- Optimised intake and exhaust cam at all rev ranges, all load, for max power and refined fuel economy.
- Modified ignition tables to suit fuelling and climate where you live, backed by our data collection.
- Rev limiters extended on all models, within safe operating limits and due to the additional power available.
- Rev limiter behaviour change, from ‘running out of steam’ to ‘abrupt rev bounce’.
- Cold start silencing, for those with decat or loud exhausts who want to keep their neighbours as friends.
- Removal of ‘dead pedal’, eliminating areas where excessive pedal travel exists before power is delivered.
- A ‘Sport Mode’ equivalent option, allowing for far greater urgency, throttle response and willingness to accelerate under all conditions. Where required, the opposite can be achieved.
- Removal of Mazda factory limiters. By removal, we mean out of reach of all typical modifications prior to FI.
- Reduced throttle shut snap at low to mid rpm, for smoother gear changes.
- Rev matching sensitivity, for ease of throttle blips in neutral.
- Need a cloned tune to cater for 91 ↔ 93, or 95 ↔ 99 octane fuel? Just ask while we are developing your tune. No extra cost.
- Tuning for aftermarket gearboxes and differential changes.**
- Pops and bangs / flames.***
** If you are fitting a new diff, like the popular 3.45 diff, you need a remap. Same if you fit an NC gearbox. The engine ECU (not gearbox ECU) calculates various inputs to determine what torque — acceleration in m/s — you are permitted to have, and will make adjustments to ensure it meets those. With a diff change what this typically means is less power, less acceleration everywhere, due to throttle being forced to close until the tables are rectified. We can accommodate for this. Get in touch.
*** Pops and bangs. Not recommended, but if you wish to try it and experience it we can put that into a tune. However be warned: it is not good for longevity, it is not great for the catalytic converters, and it will make the car run poorly off-throttle and in transient modes. But for those without cats, I know the flames can be a ‘preference’. Use at owner’s own risk.
Log your car
Capture logs on VersaTuner — full power pulls to redline, cruising speeds, driving around town. The more you send, the more accurate we can build your map — there is no limit to the data we can ingest.
Send us the setup
Your logs, a full list of mods and the fuel grade you actually run. That is everything we need to start.
Calibration
We send you three different map calibrations, chosen for your setup. They are yours to apply and log against in your own driving. Once you have put suitable time on each, send us all the data.
Get your map back
We send you your fully optimised map, created from our library of calibrations and tailored using your own data sets, and it is yours to keep.
Why your fuel grade matters
These are high compression engines. Get the ignition wrong and you can do damage. Modern engines have advanced knock detection, but that is there for safety — it should not be triggered by configuration errors.
So tell us the grade you actually run and the map is built around it. If you cannot always get hold of that grade, say so while we are developing your tune and we will clone it for the grade below at no extra cost.
Already running VersaTuner?
Then you can ship us your logs right away.
How long does it take?
Assuming logs come back quickly from your side, expect around two weeks start to finish.
We want customers to get the attention they need, so the number of people we take on each month is deliberately limited. This is a bespoke service — we are not churning out off-the-shelf maps, and the queue is short on purpose.
- Typical turnaround — around two weeks
- Monthly slots — limited by design
- Remote — anywhere, by logs and email
- In person — available for customers local to Scotland
- Dyno — can be arranged in the Aberdeenshire area
- Fuels — cloned grades are pump fuels only; E85 and blends are a Specialist Fuels job
