While attending charity event at Austec racing last weekend , i decided to put my car on the dyno.
My car is a facelift j spec running hybrids on 1.4 bar ,with 440 injectors, uprated fuel pump,colder plugs, hks fcd, hks double decat exhaust , hks boost controller and FMIC.
Ashliegh from austec racing ran it up on the dyno, But he was reluctant to run it any more as the car was running lean on the second turbo. He said that the fuel cut defender was probably on wrong setting and it should be on 8 or 9 and this should cure it.
After checking it i found it is set on 9 already. My question is can i put the fcd on 10 would this rich it up when the second turbo kicks in.
What other ways are there to correct this? Would fitting a Air fuel Ratio controller be the best way to go?
