Wil try,tq Levin 818,by the way,didt u have o2 sensor for bt?
Sorry I don't have it. Now a days it is hard to get a used O2 sensor as most of it will be removed from the H/C in Japan. This is what Mun Lee Auto Parts informed me.

E-manage can solve power delivery/smoothness problems due to slight fueling mismatch when convert from SVT to BT ecu(with trumpet)..but i always want to make sure all sensors and actuators are in good condition before proceed to something else.We need to address the root cause 1st.If all things in good condition,then use e-manage to smoothen out all the problems.
check fuel delivery system.clean throttle and ISCv
Wong,yes you're correct...if your wiring is SVT auto,then it would not have a problem to accept BT auto/manual ecu,also the a/c will not affected because the SVT auto a/c signal to the ecu is same with blacktop auto/manual.
The problem only when converting SVT manual to BT ecu,but so far i've done almost 20 SVT to BT conversions,so far no customer complaint on low idle,for such conversion,it is necessary to use a/c idle up valve.
And also when convert to BT ecu,some may go the 'trumpet' route,hence the low end fueling is greatly affected,a fuel pressure regulator will usually fixed this.Also i will suggest to each customer to fit blacktop O2 sensor for proper running (although most of them didnt bother)..
Those are still from same manufacturer with similar grade. Which mean will have problem after 15 yrs later...I think the caps look different than the earlier svt ecu isnt it Wong...
ALEX KHOO,
if i'm not mistake, i think ur AFM sensor is faulty. last time i also have found this issue before, after clean ISC, throttle body more than 3 day, the idle problem coming back again. after i tries to buy another chop shop AFM, and tries to adjust the bypass screw at the AFM (chop shop), until now more than half years so far no problem.
hi alex,
how many idle rpm during cold start engine? for my case, i had to tune fico part, angle of distributor as well. did u tried as i mentioned part?
Bro alex, how was the problem? Today when I popup my engine hood, take short look at all vacuum hose around charcoal canister. What I found is 2-3 vacuum hose already cracked. I'm gonna replace that soon.
Since your engine is almost about same as mine, why don't you change all the vacuum hose.
Cheap trial and error only.
AFAIK, vacuum hose behind 4 throttle has been changed rite?
Alex, your intake rubber piping's (connected to AFM and surge tank) clip is koyak, and your Open pod filter that mated with AFM doesn't join properly with the rubber piping. You need to sorted out this area otherwise you will always have vacuum leak at the join.
Please also find and put back the missing 4 trumpet (stock).
my SVT idling problem solved..
spray the Carb Cleaner until it chokes the engine and let it run for a minute or two..
i do it a few times & everything OK
my car idling problem still not settle!! haizz....bored go here go there workshop change this change tat and problem still there now i juz unplug the ISCV soket to drive(idling abit high 1300-1500rpm) but better than alway die engine
