i tot ae111 the o2 sensor is located at the cat con ?
u remove that thing, don't u get like high FC or something ?

 

[xMika]

usually theres two o2 sensor .. one at the exhaust manifold and one after the cat-con ..

 

[monsh]

those using 2 o2 sensor is the new cars iinm .
the old ones just use 1 .
and for ae111 design, i think its located at the cat con .

 

[FGT]

I got mine removed coz it's clogged. Naturally it became more responsive and no FC issues.

No sensor or wiring whatsoever at the cat con -- AE111 1996 4AFE.

 

[monsh]

do u have o2 sensor at your exhaust mr FGT ?

 

[FGT]

do u have o2 sensor at your exhaust mr FGT ?

Yes, but it's not at the cat con.. If it's there, I don't dare to remove LOL

 

[monsh]

Haha :P
like mr levin818 said, use it for our future generation .

anyway, what is the difference between cat con and bullet thing?

mid box and back box is the resonator to absorb the sound right? and also to filter the smoke coming out

another thing, if the outlet of the extractor is 2", can we use 1.75" piping ?
I'm planning to redo full exhaust piping soon . but most parts comes with 2" inlet or outlet. scared lose power cause piping become bigger T_T

i just want to have better power band on low to mid end. city driving only.

thanks for all ya replys, maybe my BT got other problem, the choking feel when full press really make me kecewa la... feel like want to sarong back the old 4afe engine

 

[monsh]

send for diagnostic then .
not gonna cost much ^^,
BT dude, my dream engine .
u shud be grateful u got 1 .
hehe

 

[ipul_AE111]

ok i'll go for diagnostic 1st..
i DIY the transplan before hari raya, until now did not tune back the engine
is there possible to harm my engine?

 

[monsh]

not sure .
must ask sifu .
try do diagnostic first to know if there's any sort of electrical problem, sensor problem and whatnot .

 

[lkeong88]

Midbox will not filter any smoke. Cat con is just to catalyst to help convert unburnt hydrocarbons into co2 and water (secondary school science).
Almost all transplanted blacktop out there do not have Cat con and nobody got the same problem. What do you mean tune back the engine? Is your car originally ae111 or 1.3?

my car is corolla ae111, 1.6 A, but last owner change liow to manual gbx still with 4afe engine.
now i've transplan to BT 5speed. really no expirience with BT. when 1st time drive it, feel choking2 when to start acceleration, that time, feel 4afe better. but after RPM3500 above, hehe baru can 'Get The Feeling' now i still want to find out how to solve the choking2, or BT engine is like that de.

i mean tune back the engine is, i never usik the other part. i juz plug n play the halfcut into my corolla.
is it have to go tuning the 4 throtel or anythings else? but idle timing is ok. easy to say, not yet go to any foreman or workshop. juz DIY me n my buddys here. want to save cost la hehe

 

[monsh]

chill, just try to solve the problem .
the engine is made for mid to end power .
that's y u feel better at high RPM i guess .

This is why the trend now is moving towards hybrid and even full electric design. For the next 10 yrs, combustion engine will soon become a history.

The one at the manifold is O2 sensor, at the cat-con is Exhaust Temp Sensor.
This is the layout for Levin Ae101 and Ae111. I'm not sure for local SEG's layout.

Choking = not enough fuel.
Check your fueling system ie: fuel filter, fuel pump and FPR
