Price:
£1,000 INC VAT

✔ Same-day ECU unlock
✔ Custom ECU calibration
✔ No shipping delays
✔ No extended downtime

This means you drive in, we unlock and tune your car, and you drive out the same day with real performance gains.

MINI F54, F55, F56 "B48" Tuning Guide

Thu, 02 May 2024 13:41:16 GMT

Got an F series MINI (B48)?

Want to take it to the next level? No problem!! The BMW MINI is already an extremely capable hot hatch. With the range topping JCW giving 230HP out of the box, couple that with proper handling.. they are ripe for more power!

Based in Ellesmere Port - Wirral

We are able to help with most types of upgrade, including hardware such as intercoolers, exhausts, bigger turbos and forged engine builds.

Software

We know both the MEVD17 & MG1 ECU's inside out. Whether you just want tuning, or you want switchable power modes, with launch control, pop and bang over run etc.. it's no problem!

Stock car vs Stage 1 Tuning:

'Stage 1' - Tuning a stock car.

Estimated Power, Cooper S: 270HP, JCW: 295HP.

Big Big Power and Torque Gains!

The B48 engine is BMW's 'modular' 4 cylinder turbo unit and comes in a variety of power outputs.. In both the Cooper S and JCW, the engine is massively detuned in this platform and as such HUGE gains are available..

We carefully recalibrate the stock ECU just as the factory do, which ensures not only smooth progressive power, but also that factory features such as the power and torque gauges still work (although they are recalibrated to the new power levels!). In addition, all stock safety features are left in place, meaning all factory knock control, and overboost protection still work.

Stage 1 tune, vs Stage 2 Package

'Stage 2' - Basic Bolt ons.

Estimated Power, Cooper S: 300-310HP, JCW: 320+HP

Drop the temperatures, make more power.

With huge chunks of power already found with the stage 1 tuning, you could be forgiven for thinking there wasn't much else to give.. Well, with an upgraded intercooler to drop the inlet temperatures, a decat (or a sports cat) to drop the exhaust gas temperature and some cooler spark plugs, there's yet more power and torque available!

With the catalyst removed (or a sports cat fitted), we don't need to run the mixture so rich (for cooling); this in iteself yeilds a bit more power.. couple this with better intercooling, the lower temperature charge air is more densely packed with oxygen, more oxygen = more ability to burn fuel = MORE POWER. A touch more boost, some slightly more aggressive ignition timing and further optimised inlet and exhaust cam timing give further gains still.

Again, the dyno plot tells the story here. We gain a good chunk of torque low down; and carry extra power all the way to the red line. Coupled with the lower temperatures, this is a win win!

Same car, before and after fitting Hybrid Turbo:

Hybrid Turbocharger

If you want to squeeze even more power out of your MINI, then a hybrid turbo is the way to go. At 'stage 2' the stock turbo is almost flat out and certainly outside of it's peak efficiency window. As such, any more power requires a bigger turbo, to get more, dense, oxygen rich air into the combustion chamber.

Unfortunately, due to the higher compression in the Cooper S (11:1 vs JCW 10.2:1) it's not possible to safely run this kind of power, but with the JCW you can expect big gains in power up towards the top of the RPM range. Couple this with an upgraded clutch (manual only), and you can pick up massive torque gains through the mid range too!

Dynographs:

Forged Engine...Things are getting serious.

Estimated Power, Cooper S / JCW: 380HP+

(not suitable for a stock B48A20A Cooper S)

Want to really push the limits?

If you are the type of person who has to take stuff up to the next level; then going with a forged engine, and big hybrid turbo is the only thing that might get your juices flowing.. Using all the mods from the prevous 'stages' and coupled with low compression forged pistons, and forged con-rods will allow the ability to run much more boost and thus more torque and more power.

Obviously, there are downsides... you can't have your cake and eat it! Building an engine, especially with uprated components isn't cheap. In addition, lowering the compression of the engine means that 'off boost' performance suffers; adding some 'turbo lag' to the power curve.. That said, once on boost - there are significant performance gains.

As usual, the dyno plot shows all.. We lose a bit of torque and response low down in the RPM range however, once up past 3500RPM the gains just keep on coming - on the example given, singing out to 382HP @ 6500RPM!

Peugeot 208 GTi Tuning Guide

Thu, 02 May 2024 13:41:15 GMT

Wanting to take your 208 GTi hot hatch up a level?

The Peugeot 208 GTiis a cracking little hot hatch, with fantastic handling, a great sound track and really involving to drive. With the 'By Peugeot sport' packing additional handling mods, and the same stout 200/208HP the platform is crying out for more power!

Based in Ellesmere Port - Wirral

We are able to help with most types of upgrade, including hardware such as intercoolers, exhausts, bigger turbos and forged engine builds.

Software

We know both the MEVD17.4.2 & MEVD17.4.4 ECU's inside out. Whether you just want tuning, or you want launch control, pop and bang over run etc.. it's no problem!

Stock car vs Stage 1 Tuning:

'Stage 1' - Tuning a stock car.

Estimated Power, Euro 5: 225HP, Euro 6: 230HP

Big Torque Gains in the midrange, and power up top!

The Peugeot 208 GTi comes with either a Euro V compliant 200bhp engine (EP6CDTX), or the later 208bhp Euro VI compliant engine (EP6FDTX) - both a variation on the Prince engine co-developed by PSA Peugeot-Citroen, and BMW.

Utilising slightly different Bosch ECU’s - MEVD17.4.2 and MEVD17.4.4 respectively, the approach to tuning is similar and requires careful calibration to extract the best performance.

With a relatively small turbocharger, you can expect instantaneous response, and a massive increase in torque from software modifications alone, with a reasonable increase in engine power to boot. Stage 1 typically shows a gain of 70-80NM, and 20-30bhp.

Stage 1 tune, vs Stage 2 Package

'Stage 2' - Basic Bolt ons.

Estimated Power, Euro 5: 245-250hp, Euro 6: 250-260hp

Drop the temperatures, make more power.

The biggest downfall the engine suffers from, even in standard trim, is high intake temperatures. During testing, it isn’t uncommon to see intake temperatures exceeding 70C in stock trim whilst testing the car on the dyno. An upgraded front mounted intercooler (FMIC) help to bring intake temperatures down to around 35C on a tuned engine, allowing more ignition timing to be run enabling more power to be made.

Whilst on the subject of bolt on upgrades, the standard catalyst is quite restrictive, and fitting a sports cat can free up around 5bhp, whilst a decat pipe can free up 10bhp or more. On both variants of the engine, 250+bhp and 370NM+ is possible with these modifications, and a set of cooler spark plugs alone.

At DervTech, we can supply, fit and map these parts in on the dyno, offering an easy ‘drive-in, drive-out’ service for your convenience.

Same car, before and after fitting Hybrid Turbo:

Stage 3+

Estimated Power: 280HP+

320HP+ if you are really power hungry....

Maximum power, for the power hungry.

The sky really is the limit when it comes to pushing beyond the ‘usual’ modifications on any vehicle, the 208 GTi is no exception! We have been involved in tuning projects with bolt on turbo & manifold kits, which often give a solid, and quick responding 280HP, making an extremely quick road car.

We have also taken on a number of jobs where owners have gone crazy, with large turbos, external wastegates, coupled to methanol injection, where upwards of 350bhp was made.

In addition, we've also tuned some really special one off builds. Including big turbos, built engines, cylinder head work, and custom internal components. Some of these drag cars are making over 450bhp.
