S-afc Tune

[Lexus_Rex]

I know this is a little similar to the a/f ration thread but here is my problem..

I have intake/exhaust/s-afc setup.

the s-afc has yet to be tuned :( . I really dont have the time anytime soon to go get it tuned but this is my problem.

When hitting the gas half throttle I feel as if I have major lag. I hear the exhaust tone and intake tone going real deep but nothing really happens.

For some reason I feel if I go maybe a couple points up or down on the s-afc i can knockout this problem..

help

Try going negative 5 (-5%) in the high setting. If you hear strange noises or notice some jerking then change it back immediately.

did you do all the intake exhaust and sfac at the same time?

first was exhaust ..

month later intake

month later s-afc.

did you only notice the check engine light after the sfac was put in

it might be a bad splice job

or a wrong wire on it

causing a draw instead on a sensor wire to the ecu

with the false reading giving it a lean mixture

if you disconnect the battery what happens

does the light go away and come back right away or after a little bit

after trying that disconnect the sfac and

redo the battery again and see if the light comes on again

i might be more prone to say it is the sfac wiring than an intake or exhaust

just a thought though
