Either that, or to let you know you're insane. =)

Ox sensor not affecting on the engine that it can stall. I runing my silvertop without any Ox sensor and it run wery well just eating a little more fuel...

I've put the Ox sensor, and things got better.
The engines after 3-4 times of hard acceleration works just fine, but now I get the 21 error code (about Ox sensor).

Finally the Problem was solved!!!
I've re check every line from and to the ECU and I've found out that the starter signal wasn't reaching the ECU.
Since I fixed that, a different engine was pushing my car!!!
No more lag and much much more power at the whole rpm band!!!
Thanks everyone who tried to help me out and especially Domi!

hey, sorry to bring back this topic, but i need to know how to diagnose the problem.
Im having the same problem with my BT 20V, and i think it can very well be the same starter signal problem. The reason i think so, is because when the electrician was wiring my car (ECU was already wired, but fusebox and internal wires needed to be connected) i noticed that when i switched off the car, sometimes it wouldnt switch off!!!. He supposedly fixed the problem and i havent gotten the problem since. But i DO however get this same bogging problem. If giving a little more gas, or more commonly with decelerating slightly, it gives a bog, and i believe im losing power on the whole. It's also very sluggish on acceleration from under 4K.
Im going to do the tests stated above later today, so with that said ill update whoever seeks interest in helping me.
Thanks.

If you check your starter you will see two cables...
The one (big) is for current and the smaller one is for the relay...
You will take a line from the small one and you will connect it to the ECU (str).
Or you can take the signal for the relay from the switch (where the key goes) and again sent it to the ECU.
It's not a big deal, you should manage doing it by your self...

Will do, thanks for the advice....
After some investigation, i noticed that the car wont shut off now, once the rad fan is still on. The car turns off once the fan turns off. Kinda like a turbo timer. So im thinking there something electrically wrong there.
any advice so i can check two things one time.

It seems that the engine relay is taking power from the fan line...
You have to separate those two...
