Feedback on BMW Scanner 1.4.0

[jarance]

Just got a new MAF and lambda (O2). Change the MAF and the reading is still the same as my old MAF..

Planning to replace O2 later and see what is the outcome?

Im not sure why no DME software version on my scanner result, maybe this may help :

Jarance thank god! this is the menu im refering to... this is exact mine... what can i do from here??? i cant remove HID warning... now PWM value here...

 

[xcrave]

This is the menu im refering too... its different from jarance menu... (this is from online not mine)

 

[jarance]

raymond, what are you talking about? which posting lar?

 

[Alex5522]

So Xcrave where is your Live Data and software version of DME and EGS of your car?

 

[xcrave]

Wahahahaha... real name im impressed... well its the menu haywire posted thats the menu im refering to... compared to your screen shot you have the PWM value field... this one do not have it... do you still think can remove xenon warnings?

this is the same menu as mine for LCM:

Could air flow speed a variable? i.e. when car is moving or some strong wind continuously blowing towards the car.
I just taken the readings of air mass Vs engine rpm (3 points each with and without aircon) car stationary.
Will post later.

morrogan, the reading are for no load condition on the engine. It the airflow reading when the air-con is OFF and ON.
OFF-15 and ON-20.

referring to my previous test result.

Looking forward to your chart..

p/s.. welcome to being Official Member. Blue look good on you..

 

[morrogan]

here is the chart I did for my car last sunday.
It the MAF Flow vs Engine Speed with A/C "on" and "off".

My chart looks still ok as the reading at idling is close to Mr. Herbert's new MAF. For info, my mileage ~93kkm, just serviced the car on 2/6. Took out the filter and cleaned. Reading taken during car stationary. no noticable wind condition.

Thank Jarance for your kind comment. Noted your comment that the readings were taken w/o engine load. Me did the same but I am wondering whether if external variable like strong wind blowing towards the air intake duct, would the reading be the same?

May be the MAF lifespan is directly proportion to the time that the engine is running, regardless of mileage (i.e. more idling deteriorate faster).

Thanks for your warm welcome too.

did you have any error for O2 sensor. My car have this error. I think maybe the faulty O2 sensor is making the engine
to run a bit faster (idling rpm 870).

No strong wind will not affect the reading unless the wind is about 100 km/hr. Force induction would affect.

I think don't have just these shadow error memories:
DME -> Shadow-memory:
5A/12 - Exhaust temperature before catalyst, bank 1, signal line, short circuit to negative
5B/12 - Exhaust temperature before catalyst, bank 2, signal line, short circuit to negative
5D/12 - Exhaust temperature after catalyst, bank 2, signal line, short circuit to negative
34/02 - Solenoid valve, exhaust flap, short circuit to negative or open circuit

My engine rpm after warm up (temp needle around 11'o clock) is around 700-750rpm. During cold initial start, it vibrate a bit even the engine trying to compensate/adjust the throttle. Not too sure whether due to kaput O2 sensor or not.

5A and 5B is the O2 sensor. You need to change this cos it is use for control.
5D is the O2 after the cat. Optional to change cos use for monitoring only.

O2 sensor before cat cost 350 and 380 each. The price is the cable length.

I think I know why your reading is 15(off) and 20(on). i think it due to your rpm is set at 700 to 750.

btw, when your engine warm up, what is the idling speed, MAF flow A/C on/off ?

Thanks for the valuable comment. But those are shadow error codes, so does it mean that my O2 sensor died or dying soon...? after engine warm up, it is rather stable around 700rpm. During cold condition, around 850-900rpm. Not too sure as never pay attention.

Aiyak....wallet getting burned la....

Shadow alarm are alarm that have been registered in the DME and are still standing.

yup, the O2 is dying or faulty as one of the signal from the sensor is shorting to ground.

Some power loss and higher fuel consumption is expected when running with faulty O2 sensor.

I think 700rpm for the idling speed is a bit low.

Do you feel some vibration on the steering wheel at 700rpm and
the vibration goes away when you rev it up to 800rpm?

Not necessary. BMW have introduce the diagnostic as follows:- see the transition.

1. 10 or 12 pins - OBD-I compliant - oldest
2. 20 pins - OBD-I compliant
3. 20 pins - OBD-II compliant
4. 20 pins Plus 16 pins - OBD-II compliant
5. 16 pins - OBD-II compliant. - newest.

I still puzzle what is the port on the left side of the 16 pins connector.

That is ur gong i guess...

Hahahha 1 for showroom... 1 for if anyone want to make the GB... here is sharing angel light but since it suddenly come to a lot of things at the same time... Hurmmm so more updates on the Show Room for Exterior... here is like rojak ody

BTW im doing my scanning now,... will post some screen shot and data soon... now need to decide t post here or in Jarance specific tech discussion... Alex go open new thread for our comparison can??? For all Scan data and difference in most things i think... this is due to our Japanese Lady

Bro wouldn't be a problem just for the sack of sharing Information for BMW Jpn Spec comparison owner here.

morrogan, can you post the 6 raw data. your graph is not very clear. I like to redraw it for comparison with my graph.
