The world of car remapping can sometimes seem wrapped in mystery and technical jargon, especially when discussing the importance of dynamometers, commonly referred to as dynos. Many of us have been led to believe that to get the best remap for our car, we need a dyno test. But is that really the case?
Let’s cut through the haze. Several remapping companies pitch the idea of offering you “a custom map on the dyno”. The implication? That somehow, by being connected to this piece of machinery, your car is receiving a specialised treatment.
However, the truth is somewhat different. Often, what you’re paying an added premium for is essentially a dyno printout. This document showcases the ‘before’ and ‘after’ metrics, typically using the identical flash files that you’d receive from us and several other trusted mobile remappers.
So, why this discrepancy between perceived value and reality? The reason lies in the characteristics of most contemporary Engine Control Units (ECUs). Modern ECUs, which are the computerized brains behind your car’s engine, can’t be tweaked while the car is on.
What this implies is that while your car might be revving away on a dyno, real-time modifications to its ECU aren’t happening. This is a stark departure from the operations of standalone aftermarket ECUs, which are designed to allow live adjustments. It’s these ECUs that the term ‘full custom map’ genuinely applies to.
Remapping is primarily about optimising the software instructions of your car’s ECU to enhance performance or efficiency. The process doesn’t necessarily need a dyno because it’s about adjusting software, not making real-time mechanical changes.
While dynos have their place in the automotive world, especially for certain diagnostic or performance tests, they aren’t the quintessential requirement for a successful car remap. It’s essential to be informed and ensure you’re receiving genuine value for your money. Remember, a good remap can transform your driving experience, but it doesn’t require the bells and whistles of unnecessary dyno tests.
