lexus_sc400_n20

After a week or so, i started to notice that every time i started my car in the morning it would be a very rough idle because of the mas air meter i installed from my old sc400 to my sc300. It seems to be fine once it is warmed up, so i was wondering if i should replace my oxygen sensor in my exhaust manifold to a heated one? i have a 95 sc300 and the stock O2 sensor is a one wire sensor, just 12v and it grounds to the exhaust. If it had a heated O2 sensor do you think it would help when the car is cold? Or would an S-AFC work to correct this? Anyone install an S-AFC II?

PS - I will clean up my car and post some pics for you guys, i did my Screen install w/system, rims, eibachs, tokicos, clear corners, a/f ratio gauge, built in radar detector

what injectors are you using?

prolly because you're running SUPER lean

IIRC any OBD2 1uz MAF allows a 2jz-ge motor to run 440cc injectors with minor tuning vs the stock 330s....
if you're running the stock 330s then you need an AFC to richen some stuff up

Would you reccomend the S-AFC, or S-AFC II ? i know the II you can have 12 rpm points, and do them every 200rpms vs every 500

i'd put 440s on it and then just get a AFC

i haven't seen any english setups for the afc2 yet and i won't be recommending it until i see proven results with it; i've seen proven results with the afc1 and i'm all about the idea of not fixing it if it ain't broke

anyone know of a good place to get 440 injectors with a good price/quality ratio??
