So, what’s the difference? And which is best for you? This post will give you the answers you need…
A tuning box is a small device which is plugged into your car’s electronic control unit (ECU). The ECU controls the mechanics of the engine.
By altering signals from the engine’s sensors, it essentially tricks your ECU, so it injects more fuel into the cylinders. The result is more torque and power.
On the other hand, an ECU remap actually alters the parameters within your ECU. Rather than tricking your ECU, the system itself is adjusted, so it intentionally delivers more power.
That’s the basic definitions covered. So, how do they differ?
The first clear difference is the installation process. Tuning boxes are marketed as a simple, plug-in solution, which can be installed by drivers. On the other hand, an ECU remap should only ever be completed by a trusted professional.
Next, there’s the scope of what can be done. A tuning box will only improve the performance of a car with the standard manufacturer’s settings and OEM parts. If you modify your car with a new induction kit or turbocharger, the tuning box won’t be able to accommodate those changes and keep your engine running optimally.
That’s where an ECU remap comes into play. The ECU can be remapped based on your car’s modifications, making precise adjustments to maximise performance. This gives you far more scope for improvement, with the option of a stage 2 or stage 3 remap after the initial stage 1 adjustments.
Of course, the most important difference is the performance of your car. And in that regard, there’s only one winner – an ECU remap. Because of the limits associated with a tuning box, an ECU remap can go so much further to push your car to its limits.
With a stage 3 remap, for example, cars can have a new induction kit, intercooler, exhaust, turbocharger, fuel injectors and fuel pump – all with the maximum reliability for the power boost provided.
Finally, there’s the difference when it comes to removing your tuning box or ECU remap. Because they’re simply plugged in, tuning boxes can easily be removed if you want to sell your car, for example.
On the other hand, ECU remaps will need professional assistance to be undone. If the remap includes modifications to the car, including the replacement of OEM parts, things get a little more complex – but that’s to be expected for such a significant improvement to driving performance.
Ultimately, the choice between a remap and tuning box depends on what you want from your car. If you want a small improvement with no option to go further, a tuning box is a decent choice. If you want to really get the most out of your car – or think you might in the future – then ECU remapping is the better route to take.
