Does the AF-XIED have a single adjustment? And, does it then add fuel throughout the rpm range based upon the setting?
The AF-Xied has I think 9 settings that can be selected from 1 to 9 by turning a potentiometer with a small screwdriver, anti-clockwise direction from leanest to richest. It is a simply fitted plug and play device with an additional earth wire required that connects into the lambda sensor wiring.
Lets say our TR's target AFR (air fuel ratio) is 14.7%. The ECU gets this information from the lambda sensor and makes adjustments to the fueling maps to keep this target on track. The AF-xied manipulates this information, giving us the ability to richen things up just a little bit.
· # 1 = 14.7:1 (stock)
· # 6 = 14.35 +/- 0.15 AFR (2% richer)
· #7 = 14.15 +/- 0.15 AFR (4% richer)
· # 8 = 13.80 +/- 0.20 AFR (6% richer)
· # 9 = 13.50 +/- 0.30 AFR (8% richer)
I need to try #7 out for a while as #8 didn't really work out for me.
Cheers,
