Q: Why doesn’t ECU Tuning Group tune my car on a dyno?

A: Manufactures don’t have an engineer sitting at the end of the production line with a laptop to program each car individually. All cars arrive from the manufacturer with identical programming on board. Once we know the limits of each make and model we can then program accordingly.

Q: If a customer from California buys a car from New York does that mean that the car has to be programmed for 91 octane fuel as well as the California climate?

A: No, the car will automatically adapt to changes in fuel and climate.

Q: Will I notice the difference?

A: Yes, you will notice the difference right away but the car will continue to get faster and faster as it goes through an adaptation period that usually lasts up to 100 miles.

Q: My friend had his car tuned and he couldn’t feel the difference. Why?

A: It really depends on which tuner worked on the car? Most tuners have a limited amount of knowledge when tuning cars. Obvious signs of amateur workmanship can be gleaned by asking how many car manufacturers a shop covers. If the shop is capable of tuning one type of car, logic follows that he should be able to tune any car. Software is software after all. Beware of those touting allegiance to one particular manufacturer.

Q: Will it affect my warranty?

A: Our software is completely undetectable. Most of our customers are actually factory supported dealerships.

Q: What if the dealer updates the software in my ECU?

A: This can happen occasionally during routine service of any car. We offer 2 free re-flashes; for 3 or more re-flashes there will be a charge.

Q: What if I wish to keep the speed limiter?

A: The speed limiter will be removed unless a customer specifically requests that it be left in place.

Q: What about servicing the car?

A: The service schedule and procedures remain the same.

Q: How is the software tested?

A: All files are created and tested using a Cartec LPS2810 dyno. This ensures that we can make correct measurements with DIN, ISO, EWG and other corrections. The dyno uses correct cooling fans (a $30 fan from your local hardware store is not going to simulate the same airflow when driving on the freeway). The variables in a non-controlled environment such as airflow, fuel, temperature, etc make a huge difference to the results.

Q: What If I have other modifications done to my car?

A: Other after-market modifications do not pose a problem for our software. We can create the file accordingly to facilitate seamless integration with any other performance enhancing modifications. If you decide to add an exhaust or intake, the car will adapt after 30-40 miles.
