Vehicle Dyno Tuning 101

Vehicle dyno tuning is an engine modification technique that adjusts the ECU settings to improve the power and torque of your vehicle. This article details some considerations and safety measures that you should take when conducting the modification. Ultimately it will help avert risks such as a blown engine. 

Your Tuner 

Working with an experienced tuner is the unwritten rule of vehicle dyno tuning. You should not attempt a DIY tune regardless of how well you think you understand the subject. So, why do you need a professional to tune your vehicle? Over the years, the professional has tuned similar cars and understands how various cars react to a light ECU modification. If you opt for a DIY tune, you will be confused by the many red lights on your dashboard as you adjust the various settings. 

Additionally, the professional will know how to prepare the vehicle for the tune. Remember, dyno tuning is all about results. The car should be well-prepped to get accurate results. For example, a faulty fuel injector will not squirt the required fuel in the combustion chamber. In this case, the dyno readings will be inconsistent with the ECU adjustments. 

Any Problems

There are instances when the tune does not go as planned. For example, it could affect the functionality of the transmission system. These changes are hard to detect if you have not driven a tuned car in the past. Your tuner will identify such problems during testing and develop viable solutions. For instance, in the above case, you could use a performance flywheel or detune the car to ensure the transmission is in sync with the engine. 

The Figures

You must be sure about the amount of power that your engine can handle in stock condition. Remember, the ECU is a computer that can be adjusted to any parameters. However, the engine is set to handle a specified amount of power while running efficiently. Your tuner will assess the engine and inform you of the figures you should expect after the tune. 

If these figures are not pleasing, you will need to modify the engine before tuning the vehicle. For instance, you could opt for a cast iron or reinforced aluminium block to handle the additional power. Performance cooling, intake and fuel delivery systems will ensure more boost without ruining the engine. Your tuner should advise which modifications are ideal for your car. 

The secret to a successful dyno tune is working with reputable and experienced dyno tuners. Look for a professional who understands dyno tuning.
