03 Jul Is engine remapping safe? The answer to your questions
Have you thought about improving your car’s performance?
You’d like more power, better fuel economy, and a better driving experience, but are you worried about the potential impact of remapping your car’s computer (the electronic control unit) on your engine?
Here’s our guide to the process:
How does an ECU work?
Your ECU controls different systems in your car’s engine. These include the ignition timing, the ratio of air to fuel, the timing of the variable valve and its control.
It uses information from your sensors including those for your throttle, manifold absolute pressure, air/fuel ratio, and the Lambda sensor measuring exhaust gases.
The car’s manufacturer has written the software for the ECU and decided on the parameters which show the engine is running normally. Any signals outside these parameters would show up as faults, and fault lights on the dashboard would be triggered.
The problem is that manufacturers must factor a lot of things into their calculations when devising the parameters for your engine because they must assume a worst-case scenario – including neglect, a lack of servicing, and poor-quality fuel.
If you’re using good fuel, like we have in Britain, and take care of your car the parameters don’t have to be so loose.
So, is remapping safe?
The quick answer is yes, this is a safe process.
The longer answer is this: remapping modifies or replaces your existing software which is optimised for cars which run on good fuel and are cared for by their owners.
The new software remaps the pattern of how the ECU controls the points between the car idling and throttle cruising.
This means the air to fuel ratio, calibrations, the ignition timing, and boost pressure can all be changed.
The key to making this work well is getting experienced remappers to carry out this process.
Each car is individual and engine tuning should be carried out by experts and be bespoke to your engine.
Always call in the experts
You must ensure remapping is carried out by experienced staff.
At Eco Techs, we’ve successfully remapped the engines of vans, lorries, and cars and have testimonials from our happy customers. You can read them here and here
We have thoroughly researched the remapping and retuning methods we use and can advise you how best to ensure the extra torque and power you gain doesn’t put a strain on your engine and components.
Many drivers who use their car on the track or want maximum power choose to upgrade other components like the injectors, turbo and intercooler at the same time their engines are remapped.
