TRE FOR 09 BUSA

[GRUNTMAX]

If the O2 Sensor is not important, then why, when you've got a bike on the dyno do you have one in the exhaust stack that takes an average Air Fuel Ratio of all 4 Cylinders ????
Torque is more important in the first 4 gears, not top end HP.
With the PCV you can make AFR Maps for all 6 gears, train your fuel map with the Autotune & real road riding, not the dyno. Then trim the AFR on each of the 4 x exhaust headers with the EGT meters & the PCV.
Can you trim all the injector pulse withs up on each of the 4 cylinders with the ECU Flashing Interface Pete ? Would be good.
