Big Fish Tuning – NEW Mercedes CPU Upgrades!

What is a CPC Module?

A CPC is your cars computer powertrain control module. Not to be confused with the vehicle’s ECU (engine control unit) the CPC module controls many features of your modern Mercedes such as the throttle pedal, active exhaust valves, and speed limiter.

Why Do It?

In modern vehicles the CPC module controls some key features which impact the parameters of the ECU settings. Our newly available CPC module replaces the OEM CPC allowing us to improve your vehicle’s performance and derestrict the ECU in ways that tuning alone cannot. Within our new offering we can remove the speed limiter, allowing for higher top speeds, raise the torque limits, and even adjust your active exhaust valve settings to match your Mercedes to your driving style.

How Much?

Our module has been priced at a competitive £995 which is one of the best prices available at the moment. As well as that our pricing is all in which means that it also includes fitting and dyno testing with print outs.

Fancy adding on one of our custom tuning sessions at the same time? That’s no problem, Big Fish Tuning offers a full service, and we can tune your ECU whilst you’re here. All of our custom tuning is done live on the dyno with print outs and a pre-tuning general health check from £695*

Ready to go? Just send your VIN number to to ensure compatibility and a member of the team will come back to you to confirm and get you booked in.

*Pricing assumes that the vehicle is otherwise as standard. If you have made other modifications to your vehicle then please do let us know as modifications take more time to tune in.

Big Fish Tuning is proud to announce our new partnership with Motorsport Electronics Ltd. Motorsport Electronics Ltd was born in 2010 from the collaboration of two software and electronics engineers tasked with the creation of a bespoke ECU for a Le Mans prototype engine. They were able to implement and build on the technology developed during this project, allowing them to bring to the fast-road/race market advanced engine management systems at reasonable prices.

ME design powerful engine management solutions using the latest technology and design principles – pushing the boundaries, while maintaining cost-effectiveness for our customers. They have tailored their software and features based on feedback from their wide network of tuners and other motorsport professionals, so that their systems are intuitive to use and deliver proven results time and time again.

“It has been a privilege to collaborate with some cutting-edge companies in the UK and Worldwide – from perfecting the ME221 Plug and Play ECU for the MX-5 in collaboration with Flyin’ Miata, through to developing the Jaguar V6 version of the ME442 for use in the MX5 Rocketeer Conversion Kit.”

  • Plugin ECUs

    ME’s PlugIn ECUs are great for a simple and rapid installation and support for factory sensors without the expense of building a new loom. You are able to re-use the factory enclosure After the success of their MX-5 ME221 plug-in ECU, every major MX-5 tuner in the UK and many around the world, including Flyin’ Miata in the USA, recommend Motorsport Electronic’s ECUs. They have since broadened their range of plug-in ECUs to suit a wider range of models and even more are in development. The ECU fits in the factory case and connects to the stock ECU adapter. A short video demonstrating the ease of install can be found here as well as this CarPassionChannel video here

    ME’s PlugIn ECUs are available as an ME221 or ME442 version with on-board wideband lambda and SD datalogging (see table below). All Motorsport Electronic’s ECUs use the same MEITE software which is very user friendly and intuitive for the calibrator.

  • ME442 Universal ECU for up to Eight Cylinder Fuel Injected Engines

    Launched at the Autosport International show in January ‘18, the ME442 is ME’s flagship ECU and supports fully sequential injection and ignition for up to eight cylinders (sixteen in wasted-spark mode). Its features include an in-built wideband controller (LSU 4.9), drive-by-wire, dual VVT control, on board data-logging, general purpose tables and much more!

    The full technical specification and listing can be found here

  • ME221 Universal ECU for Four Cylinder Engines with Fuel Injection

    One of ME’s popular products is the fully sequential, ME221 Universal ECU (fuel injection + ignition). It is available with an unterminated loom as well as other premade loom options. It is perfect for ITB or turbo builds using four cylinder engines and supports a wide range of crank/cam trigger patterns.

    For example, an ME221 ECU with a Ford (e.g Zetec, ST170) or Vauxhall (e.g. C20XE) pre-terminated loom is available for only £662.50 (£795 incl VAT) and this has all of the connectors ready to click into place for ease of installation (you can see a short video install guide here showing how easily this is set up).

    The looms that ME supply are made in a UK factory and are machine crimped as well as electrically and mechanically tested. The ECU also supports high resolution VE fuelling and ignition, closed-loop VVT control, boost control, switchable maps and windowed DSP knock control and it has been very popular with customers due to the loom quality, features and cost-effectiveness.

  • Nodiz Pro Ignition ECU

    You may also be interested in the Nodiz Pro. This ignition-only ECU is also very popular for customers running engines on carbs and features a 16x16 ignition table, support for any 36-1 and 60-2 trigger pattern, launch control and a free bluetooth dashboard for android phones. Included with the Nodiz Pro is either an unterminated loom (where you can add connectors to suit the engine), a Ford style plug and play loom or a Vauxhall style plug and play loom e.g. for C20XE engines at £249.17 (£299 incl VAT).
