How is your fuel efficiency? Did it improve?
What if by accident you let your friend fill up your car and he'll put 91oct and u got a program for 93?
The thing is that im still under warranty, would an audi mechanic be able to see software upgrade ones im in for a warranty repair?
I heard now the offer an optional switch on your cruz.control incase u want to go back to stock.
Don’t buy into the fact that companies claim possible better fuel economy. I have never seen proof of this. I don’t believe it. People have made the ASSUMPTION that if you have more power, you don’t need to push the gas pedal down as far to get the same amount of acceleration – thus using less gas…. THAT’S A BUNCH OF HOOPALA in my opinion.
Essentially, the chip will be producing more boost, with the fuel mapping to match. The chip may also modify the timing somewhat. Without making any changes to how your car breathes (i.e. better breathing by means of; match-porting, more efficient intake and/or exhaust plumbing) – I really doubt that you’ll get better economy. Without changing the breathing of your car, you still need to burn the same amount of gas to make the same amount of power. A chipped 1.8T has the ability to produce more power because you are forcing more air thus more fuel (to maintain proper air/fuel ratios).
Basically, my point is that I truly believe that there is no potential to improve your fuel economy with a chip - unless the timing is maximized for fuel economy. I still haven't seen good enough documented proof to support this to change my mind.
It is however very possible to maintain the same amount of fuel economy after chipping, providing your driving characteristics are the same. You will consume more gas though if you floor it chipped, than if you floor it stock.
In my case, APR was able to put both the 93 oct program and stock program in my car. They can be switched via the cruise ‘set’ switch.
Also – what the hell are you doing letting your friend drive your car?
Avoid running less than the recommended octane. It can cause pre-detonation which ain’t the best thing for your motor.
As for warranty – if the dealer can detect the chip, and you are trying to get a turbo replaced under warranty – you may have to fight for it. If you’re in for control arm warranty, you’ll be fine. Ask the APR guys about how hard/easy it is for the dealer to detect.
A chipped 1.8T =
a happy driver!
