Dyno Tuning is high tech tune up of your vehicle, specifically the engine, by a suitably qualified mechanic.

The term ‘Dyno' comes from the specialised equipment used in the tune up, called a dynamometer. Using a dynamometer, a qualified Chapmans Auto Repairs automotive technician can measure engine speed and torque, which can then be used to calculate engine-power output.

All this can be achieved safely and without your car ever leaving the workshop. Dynamometers use rollers to allow the testing of specific speed or torque settings under controlled conditions. This then allows the mechanic performing the Dyno Tune to fine tune your engine based on very specific test results.

Adjusting the air/fuel ratio to better suit your type of engine for example, can greatly improve performance yet maintain maximum fuel efficiency.

One of the biggest advantages of a dyno tune is the fact that the car is tuned based on the results of testing under various driving conditions. This means a Chapmans Auto Repairs mechanic can tune your car to perform at its best when it really matters - while driving it.

A vehicle on the dynamometer, with the driving wheels on the dyno rollers, is tested with the engine running, in gear, and under various speeds and load conditions. The mechanic is then able to fully monitor the engine performance via a computer and compare the horse power transmitted to the drive wheels against the amount of vacuum present in the engine.

Fuel and air levels are closely monitored whilst checking the carburetion throughout each circuit of the carburettor. The mechanic then makes adjustments as indicated by the results of the dyno tuning. The actual adjustments made and the time it is likely to take will depend largely on the type of car being tuned, the normal driving application of the vehicle and any other information you have supplied to the mechanic on booking the car in.
