Wira 1.6 ECU

[ylkien]

Hi,

I need to change my ECU unit cause it seems to be giving problems where the car jerks when accellerating. Throttle unit is fine. Does anyone know where exactly us the ECU (that controls the engine and gear box) located? Anyone has a recommended shop that sells original wira ECU?

Thanks.

my opinion is ECU is like a brain.. is Kaput.. engine wont be able to start lor...

try simple solution..
-clean inside distributor cap
-replace new standet spark plug
-remove battery for at least 12hours..

as this is simple one.. why dont u try first..
i always remove my battery more than 12hours every month..
the result after it might surprise you...

cheers..

not much cost... beware petrol price are going to increase...

Sorry, forgot to reply in here.

1) it is an auto car. The "check engine" is always on, and proton mechanics say they can't find the fault^^

2) The car is >10 years old. Auto (very troublesome). My car jerks only after travelling 1 hour +

3) I found the ECU, somewhere near the back of the radio. Got a replacement (RM250) from chop-shop. Still testing :)

4) huak : I don't see a "RESET" button on the ECU box.. Maybe i'll post a picture here.

5) Routerzz : I have changed the spark plugs (including cables), and the throttle. I don't see the reason of removing the battery for such a long period of time.

Anyone has a complete list of sensors in the wira?

Anyone knows where i can get a 1.8 turbo manual half-cut (evo or proton)? I can only find an auto half-cut.

Thanks.

reseting the ecu is by removing the battery...(guess u can combine the 2 advice into 1 =P )
remove how long? its up to the ecu. proton if not mistaken bout 4 hours(test based...)...honda 10 mins - 1 hr.

could not find the fault? but they can plug in to the ecu and check the error code wert...

maybe it could be the fuel delivery. check the fuel lines...change the fuel filter...could be clogged...clean injectors...haha...last time my friend's car jerk...coz of not enuf fuel! =P

anyway...good luck on locating ur problem!

ECU has permanent memory and accessible memory...

disconnect battery is to make the ECU return to its factory setting .. that all.. if something wrong it will be a problem again..

as my car sound really smooth(almost like engine not running) every time i do like this.. just to share...
