Lexus AFM and Stock injectors!!!

justin1642 · 08-14-2006, 10:17 PM

ok i do plan on getting 550 or 680 cc injectors with the Lexus afm. but for now i am going to have to run on stock injectors and i was wondering if i just adjust it with the screw if i should be fine or if i don't change what problems i could have. also i was wondering if anyone recommends getting the walbro fuel pump upgrade with it. thanks!!!!!!1

you could run lean and fry your engine

do you have an air fuel gauge to measure the mixture you are burning now ?

no i don't but what about tuning the afm down.

without some kind of air/fuel mixture gauge you will have no idea if you're running rich or lean

another question is the lexus afm electronics in the black box on it should just be plug into my sensor plug and be good to go right? and should i buy the apexi s-afc when use this upgrade.

but an air/fuel unit , or meter, even a gauge
they have plug and play ones now
you can plug it or hotwire with your afm
so at least this way you wont be guessing

tunning the afm down what you mean? so you can run rich?
what if your running rich enuff already? or lean enough already?
jus get the gauge at least first

i dunt wanna hear about another car thats gonna go down bcuz of something like this
