mpg

 

Does chipping it really use that much more gas?

 

not really...like 3 mpg, i just that it might be a reason for stock

i've had mine on stock for the last week because i bought it with the chip and want to see what it feels like stock compared to chipped

 

No I do it.. No probs at all... All your doing is just telling your ecu to change up the fuel/air ratios.. and allow more boost...or vice versa

 

Actually, I got improved mileage when I chipped my car. Of course, if I punch it, that is something else.

 

it's hard to lay off the foot when its chipped too

 

depends if your ecu was soldered or flased. flashed you need to switch with car off, if its soldered you can switch on the fly, but APR rep did tell me its better to switch while stopped, not sure why but it wsa for mechanical reasons not just safety.

 

Noooo... Don't switch the programs while drivin!!!!! High boost to low boost is ok but low boost to high boost will spike the turbo and can cause you to throw a rod. I found this out the hard way here's some pics of what happens

This used to be a Boosted K20








If you want to change it while driving throw the clutch in let it idle then switch the program then go back to driving.


*That 3rd picture- Yes that is a screwdriver holding the engine on the stand. The rod blew off the engine mount when it went.*

 

nice pics man, must have been one hell of an experience from inside the car... so driving, putting the clutch in and coasting and then switching the chip, and letting the clutch out is cool?
