yup. better in response. the hissing sound is loud after running for a while. i scare AFR too rich. i wan to install piggybak, but currently no budget for tat. so asking if no install piggybak at the moment ok or not
i also have this idling problem..banyak sakit kepala now...haiz...my car tat day done
- Clean ISCV
- Clean 4-throttle (strip into piece)
- Check all vacuum leak and change many hose
-clean airflow meter
after drive 2/3 day then the idling back to b4!!!
auto or manual?I m having odd problem with my BT too. If AC on to the max. When I slow down to stop. The engine will mati.
Anyone knows what s wrong with the car?
Sifu Levin 818,can you identify that ecu,i also came across this ecu once...Hi all, just wanna share my experience.
I've converted my car to this spec:
SVT wiring mated BT ecu with BT aircon compressor.
And my stock SVT ecu is like this, donno early or later model.
What I notice is idle up valve is not active anymore after using BT ecu.
Thus, I've also experience engine stall intermittently.
From my observation, my engine will stall immediately when I release throttle pedal.
After sometimes, I've DIY narrowband O2 sensor for monitoring.
What I get it, at the time I release throttle pedal i saw the narrowband sensor is too lean.
This is becoz fuel cut at that time and I also noticed that RPM gauge is at around 600rpm.
Sometimes it goes as low to 500 rpm and engine jerks a while before fuel is supply again.
What have I done is I increase fuel pressure using FPR (my AFR is still ok after tested with wideband).
So as a result, my engine is less stall now but still I felt it jerk at fuel cut time.
TPS setting is out, or O2 is dead.My b.t also need help,engine slumbing during 1st and 2nd gear,rpm below 3,000
But high rev is ok,did any one know wats going wrong?I already try to adjust ignition timing,replace s.plug,s.plug cable,fuel pump and sard fuel regulator:......
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.Wow... this is brand new ECU that previous car owner bought from DENSO. Date code could be 1999 or 2000. Much more newer than stock (1992~1994)! From DENSO code, it looks like mated with 89661-12771. If you can show the internal picture, i will be able to identify.
Rahmat, my car is running with '92 A/T wiring but it can run with all auto and manual ECU w/o any problem on the A/C system (run manual ECU with converter). So i still think that those ECU deliver tha same level of signal to the A/C controller... But thinking of which, there are R12 and R13 aircon gas being use in Silvertop so signal level might be difference in difference gas. But jus that i did not experince any significant difference on those ECU.

I have run a converter on my silvertop wiring to accept BT ECU. The result is good on the idling and eventhough with A/C turning ON/OFF.
If your idling is too low probably your conversion of the signal is not right or ISCV is clogg.

Alex, go find back your ori trumpet and rubber hose clamp (for AFM and Surge tank). Those are the area that you have vacuum leak.
I think the caps look different than the earlier svt ecu isnt it Wong...Here is picture as per requested
