TUNING FAQ'S

General preparation is key to a no hold ups, successful tuning session.
This ensures you see the most benefits.
A quick checklist guide - 

Check Fluids - Make sure your Engine oil and coolant are topped up.

Check for leaks - Not only Oil and Coolant leaks, but also Exhaust leaks (big one!) and Boost leaks. (if applicable)

Full tank of Fuel - We will require the vehicle to have at least 3/4 tank of fresh, correct RON fuel that you will be running the car on. (your regular reputable servo)

Wheel lock key - Remember, if you have aftermarket wheels with lock nuts to supply the key in an easy to find location for us to get your wheels off without holdups.

Bring receipts/Specs - Any engine performance modifications we need to know about on the day of the Tune. (Cam Specs, diff ratios etc)

Engine codes - If you have an engine light or codes present, these will need to be sorted prior to the Tune. 

Dyno tuning is usually fairly straightforward. Depending on the vehicle, engine modifications, general condition and ECU access. It can usually be completed in several hours. Ideally, we aim to get every vehicle out the same day its booked in. 

Different dynos measure differently, this is true. It becomes almost impossible to tune a car on 2 separate dynos and achieve the exact same result. There are many factors that contribute to this from the day to day external differences to the dyno itself. This difference can be considerable so if you are needing a comparison Tune, its best to do all runs on the same dyno.

Some workshops will lock the ECU after they tune it. 
We have software that allows us to unlock most factory V8 Holden ECU's. 
This can take anything from a handful of hours, to days. Once it is unlocked, its a blank canvas to then get the car on the Dyno for a fresh Tune Corp tune!

This process costs a small fee and adds more time to the job. Generally unless difficult to unlock, will push your Tune booking over 2 days.

We don't lock our Tunes here at Tune Corp.

When your tuning session arrives, its best practice to have fresh fuel in the tank. You will need to have at least 3/4 of a tank minimum. We usually recommend you fill up from your usual service station. Best to stick to reputable brands. Make sure you have the correct octane fuel required for the Tune. 

If your vehicle has been modified or even if you notice decreased engine performance. Some engine modifications require dyno tuning before you can properly drive the vehicle. These include most if not all performance engine upgrades. 

Short answer, Yes. 
Both are significant changes enough to confuse the ecu leaving the vehicle running poorly. Both exhaust and intake modifications are done to gain performance, that is only achievable with a Tune.

A Tuning session on the dyno puts the same load on your car as driving at full throttle on the road. If your car cannot handle this normally, it has underlying issues that a dyno may reveal. Ensure your vehicle is well maintained and prepared before the Dyno session.

This will depend on what numbers you are relying on. Keeping in mind different dynos result in different numbers. Every car even differs slightly!
If numbers are genuinely low, the Tuner can investigate and be able to advise if they think there are any issues that require attention. These could include exhaust leaks, faulty injectors, fuel quality/pressure issues, Bad spark plugs. Most issues don't allow for a proper tune until fixed.
