Engine Calibration or Mapping

Should a potential customer damage their engine, we recommend either sending the car to us (collection service available if required) or they remove the engine and send it to us.  Customers who opt to strip the engine and carry out their own investigation can end up costing themselves more in the long run. 

If you were happy with the way your engine was previously running prior to the failure and you’ve suffered an engine / component failure we will aim, where possible to simply rebuild your engine to it’s original specification.  As a lot of the engines that we work on are supplied with a locked ECU, this means we cannot make adjustments to accommodate changes made to your engine.  However if you decide you would like changes made where adjustments to your calibration are required, we can supply a new unlocked ECU and a new calibration can be produced.  If budget is an issue then rebuilding your engine to it’s previous specification and using your original ECU is the cheapest way to get your car back on the road.  You will, however, find that manufactures of these cars use generic calibrations for the engines, and try and keep their costs down by not testing and setting up every car.  We have been involved with re-mapping some of these cars where customers have had driveability issues.  To give you an example, we’ve had customers bring cars to us that have a flat spot when driving in traffic.  This is where the car appears to jump from the slightest throttle pedal movement.  We would put this car on the rolling road and initially produce a power and torque curve at full throttle.  The locked ECU would then be removed and an unlocked version fitted and a new calibration produced.  At the end of the test a new power and torque curve would be produced.  As a result of this, the cars generally are much nicer to drive, are more fuel efficient and in some cases, we’ve seen some good gains in top line performance.  I guess this could be compared to having your own road car “chipped”. 

Where possible, we produce calibrations using supermarket 95 octane fuel.  Customers often prefer to run the engines on super unleaded.  As a lot of these cars are used for touring, if we mapped the engine on super unleaded and super unleaded was not available at some remote petrol stations, putting 95 octane in this car could damage the engine.  However mapping on 95 octane means this situation shouldn’t occur.
