Hello guys, just wondering I just install the afr and take for ride just observing on the afr...

since my o2 sensor is busted so I use the brown wire from innovate and connect it to the o2 pinout.

at idle i'm seeing 16.5 average.. then at first i seeing 12.5 at cruise like around 60kph... since i just install it seems the ecu is starting to learn.. around late night it started to go on 14.5 at crusing speed.

when I take a spin on WOT i got 10.4 @ .5 boost.. seems i got boost leak since even i try to adjust my manual boost it don't raise. would this be fine? it seems 10.4 is quite over fueling. so would it be more safe if i increase my boost?

thanks in advance Smile

Absolutely this. Find and fix the boost leak as this will play havoc with your MAF readings (and hence engine load and injector pulsewidth values). Once you fix that you can begin to tweek the maps.

Cheers,
Dave
