It will give you an additional 5 % more BHP. BUT YOU WILL LOOSE OUT ON FUEL EFFECIENCY. The normal setting we have found is the best you can get of both worlds but ofcourse it depends on a persons taste.
BUT , if it improves perfomance without a loss in fuel efficiency then why do the car manufactures not setup their ecu's with the same settings as the tunning box ????
Good point - Points to note in regard to this;
1) Some cars do have this option like for e.g. The Alfa Romeo is doing a special edition 147 with a Power Box. .
2) Some Countries have tax and insurance proportionate to the original power of the engine, so a more powerful car pays more tax and insurance.
3) Some manufacturers in certain Countries propose an increase as optional.
4) The ECU’s for a particular Car are usually manufactured in one of the plants for the whole world. Certain countries cannot accommodate excess power due to the low quality of fuel so the car is manufactured with a lower power output for the whole world to reduce overhead costs of making different ECU’s for different countries.
5) Hey and you need the knowhow - Guess Skoda and hyundai dont have it . JUST JOKING
So taking all these parameters into consideration I guess SKODA or HYUNDAI had some economic problem. Moreover the Skoda is available abroad with both the 90 BHP and 115 BHP Engines.BAsically same engines with different ECU's.
tsk1979 i have one query. Did you guys go for an emission test. I am just curious wether the octy remains an Euro III after the box too.
Next surprise - Try an emmission test and get back with the results. In the normal setting the car WILL PASS.
