Turbotune Tuning Boxes


  • Lifetime Warranty (while fitted to same vehicle) or 5 year transferable warranty
  • Free fitting at our workshop

The Turbotune uses low power RISC micro controller technology that digitises the sensor signal(s) 10,000 times per second, meaning that this is a truly digital module. Current consumption is negligible so no extra battery connections are required. Reliability is excellent with negligible failures and this is why we now offer a life time warranty.

The signal is then modified in the digital domain to reprogram the fuel pressure, overriding the engine ECU, to permit increased fuelling and therefore torque. This increase is in relation to driver demand and engine rpm so accurate control is possible more or less anywhere in the rev and load range.

By incorporating 9 fuel modifying maps in the firmware, we can cleverly provide separate switches that control the torque enhancement at low/mid rprm (below about 2500rpm) and mid/high rpm (above about 2500rpm). Hence you can choose to have just more low down 'pulling power' - ideal for motor homes and vans, or more 'top end' for sporty fast road use, or both for the power mad!

The on/off switch allows you to bypass the unit and return the performance to standard. Switch it off for a few days now and again to remind yourself of just how effective the unit is!
