Just had my MK2 st225 remapped first ever time doing this kind of thing and as soon as I turned up they made me feel at ease straight away, got it on the ramp, done a health check, run all run perfectly fine and then run the remap, completed the map and was absolutely great. Would recommend Redline Tuning to everyone I know...   J. Brown | Focus MK2 ST225

The Remapping Process | Diagnostics Check.

Performing a road test & diagnostics check is the first & most fundamental step to our engine remapping process. Redline Tuning will only perform a remap if your vehicle is in a fit and "tuneable" state. There is no point in calibrating an unhealthy engine - this will just result in wasting your time & money, and you'll miss out on the full potential of your flash map. 

Would you give your elderly grandparent a pair of roller skates? Probably not.

The Remapping Process | Loading & Calibration.

Once we've deemed your vehicle suitable to be mapped, we'll then calibrate the flash file, ready to be loaded onto your vehicle's ECU (Engine Control Unit). In some instances, the actual tuning files can be slightly modified to suit the condition of your vehicle, or the application of your tune (Road vs Circuit). Sometimes, a "one size fits all" approach is not the most effective way to achieve optimal performance figures.

The Remapping Process | Dyno Runs & Road Testing.

Once the file has been appropriately calibrated & loaded, your vehicle is then road tested by one of our technicians to ensure the file is optimised correctly.

Optionally, we can also perform a dyno / power run on our 4WD DynoDynamics Rolling Road in order for you to have visual proof of your power gains, and for you to have complete confidence in the modification we've performed.

Is your vehicle's engine modified...?

...Introducing the Unichip.


If you've got a handful of engine modifications, then pay attention. 

Flash mapping is ineffective. Standalone ECU's are beyond your budget.

The Unichip Module gives you the best of both worlds. Installed between your vehicle's ECU & your engine sensors, the Unichip intercepts ECU signals before they reach sensors, to manipulate engine parameters.

In most instances for "lightly" modified vehicles, the Unichip will do everything you'd expect from an aftermarket ECU, at a fraction of the cost.

Installed on site, live-tuned on our dyno, loved around the round; visit the official Unichip Europe web page or contact us to book your consultation.

...I seriously don't have enough words for it. Just gobsmacked. It has unleashed some serious power on the 1HD-FTE [engine] especially at low revs. Car pulls like a train and just keeps going going going. I wish I had done this sooner!  - P. Shah | Unichipped Land Cruiser "Amazon" 100 Series.

Engine Tuning and Avoiding Charlatans. 

These days, the engine "tuning" industry is saturated with more companies to choose from than there are cars on the road. Okay, maybe not that many - but exaggerated claims like the above are similar to the power figures you'll be quoted from some of these mobile mapping / tuning charlatans - and usually for a "too good to be true" cost, too.

If your mother taught you anything growing up, you'll know to avoid snake oil pitfalls like this. However, it's very, very easy to get sucked in on a bargain.

Simply put, the majority of mobile mapping carried out by these companies will give you a sizeable increase in power. However, these figures can never be verified because they do not have access to a rolling road to physically prove the figures they've quoted.

Furthering this, if these grandiose figures are genuine, they'll likely damage your vehicle.  Signalling to your engine to give it more power when the rest of your stock engine components can't handle it is a recipe for disaster, and will cost you more than the loose change you scrimped on for a replacement engine in the long run.

The tunes provided by these companies are typically a "one size fits all" approach, with no regard to your engine's condition. There's no guarantee that the tune you're receiving was even from the UK, either. Varying climatic conditions, fuel quality & even air quality have a massive effect on how your vehicle is tuned and how your engine behaves.

Moral of the story? Know what you're buying, avoid "cheap tune / big power" charlatans & always get any serious engine modification done by professionals. Redline Tuning are motorsport tuning experts & are already giving you the most amount of power feasibly possible - avoid Dave in his leased Transit claiming to give you double.
