Mr. WRX

Hey all,

Had a go on the Rollin Road and the air to fuel ratio was out (was to high)

Can this be adjusted with out the ECU being unlocked?

Cheers all !

Too high? Do you mean too lean i.e. too much air, compared to fuel?

Mr. WRX

Cheers wrighty338!

Bet they are akward to fit hmmmm im a bit stuck here, i want my Afr to be correct, the rest of my car is running sweet! No point paying for ECU to be unlocked if i just want to change my afr to 11.1 .... there has gotta be a way with out to much hassle

You need a remap, end of. If you don't want to use ECUTek, find someone that will Open Source map the car.
