Every car owner wants to get the most out of their vehicle, but few are willing to do what it takes. Notably, you can add performance parts to your engine, but your efforts will be futile if you do not make the necessary changes to your car's ECU (Engine Control Unit). The best and safest way to get more power from an engine is to take your car for dynamometer (dyno) tuning. It involves strapping a vehicle on mechanical rollers for a couple of full-throttle ramp runs. That said, the success of any dyno tuning hinges on proper preparation. This article highlights crucial checks for optimal dyno tuning.
Exhaust System Leaks
One of the first things you must check before delivering your car for dyno tuning is potential exhaust system leaks. Notably, exhaust system leaks, including in the manifold, cause backpressure issues, leading to slow spool and lean readings. It is mainly the case with turbocharged cars. Persistent leaks also lead to calibration issues, significantly affecting a dyno tuning exercise. Unfortunately, such incidences can cost you a lot in time and money. Therefore, check for signs of leaks throughout an exhaust system by inspecting for carbon build-up. It is advisable to replace the gaskets in an exhaust manifold, downpipe, or turbo when you identify a leak.
Spark Plugs Inspections
Spark plugs are commonly ignored when preparing for dyno tuning. However, when a vehicle undergoes the procedure, spark plugs must run within the optimal heat range. Since dyno tuning involves running a car in full throttle mode for an extended period, spark plugs must withstand higher boost pressures. Therefore, if spark plugs are in poor condition, the chances are high that dyno tuning will give an inaccurate picture of your vehicle's power output. Consequently, it is vital to ensure that spark plugs are in optimal condition to avoid calibration issues during dyno tuning. Otherwise, you risk blowing spark plugs when a vehicle is under full throttle.
When your car is strapped on a dynamometer, it is subjected to high speeds for an extended period. Therefore, you must ensure that the tyres are up to the task by inspecting them for adequate pressure, leaks, and tread wear. For instance, you should replace any worn-out tyres before showing up for dyno tuning. Besides, any foreign objects on tyres, such as spikes, must be removed to prevent damages to a dynamometer or injuries to a technician.
