Normally Aspirated Engine Tuning.
Evolution Chips have been tuning and modifying normally aspirated engines for over 15 years. We have upgrades available for most petrol non turbocharged vehicles.
Understanding engines is key to power gains...
The normally aspirated engine, whilst not the easiest of engines to tune can still benefit from up to 15% more power and torque by careful programming of various engine parameters within the ecu such as its fuel and ignition maps, and in some cases the cam timing can also be tuned within the maps.
In many cases, conventional tuning items such as exhausts, air filters and camshafts need to be optimised for the engine via careful ECU remaps. Engine remapping will almost always unleash further power from fitment of those type of items on a modern vehicle so always have you vehicles remapping done last. .
All our normally aspirated engine remaps are programmed to give a strong, linear power delivery right across the rev range.
Rest assured that we don’t just look for a torque and power peak to make the numbers look good. We aim for maximum safe improvements everywhere so the vehicle feels like it has a bigger engine. Take a look at this video of our BMW 335i stage 2 remap for an example of how the gains should be nice and linear across the rev range.
How is the extra power achieved?
The power and torque improvements above are all achieved by very careful matching of parameters such as fuel delivery rates & Ignition timing along with adjustments to maps that electronically limit torque, throttle response and cam timing. All this information in your ECU calibration file is carefully optimised to our exacting standards and then programmed back into your ECU. The vehicle is then tested before we send you on your way.
Buy with confidence...
All our normally aspirated petrol engine OBD tuning comes as standard with a lifetime warranty against defects and corruption of the product and of course our standard 30 day no quibble trial period.*
|A 30 Day No Quibble Trial Period Available|
|A Lifetime Warranty On All OBD Port Remaps|
All remaps are not equal...
As a final note, please, before buying any turbo petrol performance chips or having any OBD turbo petrol remapping done, please take a look at our "Remap buying considerations" page to ensure you don't fall into the trap of buying from a turbo petrol tuning company that may damage your vehicle.
