rs2 engine problem!(help)

[UrS4boy]

by the way can g40 sensor position cause this problem?

The G40 Hall sender (in your "3B" distributor) will stop a car from starting (and sometimes make a running car stop) but it won't make a running/starting car miss like yours is.

[UrS4boy]

thank you for your opinion but this car is still a rs2

No ADU = not an RS2 any more, just an Audi with Porsche wheels, brakes and mirrors.

I have no more words...
"mapper does not accept this situation and blames the problem on crank sensor "
I am getting old or poeple changed?

Or VEMS detect trigger problems?

OK, tomorrow send me it.

Hi,

I have equal problems with 4 cyl engine, in VW Polo G40 too with VEMS unit.

Have you Scope?

If yes measure PWM in first injector and secound... to five.

I suspect you have bad configuration in Injector division by X injectors...

See it please

could you please explain briefly i could not understand?

i can send you my config tomorrow to the mail that you^ve given. by the way can g40 sensor position cause this problem?

Send me your config file to: Info@chip-fuse.pt

The sound seems valves leaking in intake.But it is not relevant in a video recording.Could be just the misfire(timing,fuel etc).Who maped it?

i also think it is bacause of the map. but the mapper does not accept this situation and blames the problem on crank sensor

first time i see rs2 with an old 3b engine... IMO its not rs2 anymore its just an 80 avant... but good luck with your problems.

this is the current motor but in the future the motor may change beacuse we think to have high horse power. most probably if the car works without problem it will surely be broken down in the future and than the motor may be aby or adu again. thank you for your opinion but this car is still a rs2

Have you got oil pressure sounds like the head is dry

there is no problem with the oil pressure. actually the motor does not work very loudly but maybe because of the recording it sounds noisy. oil pressure seems normal.

Post your config or email it/pm it to me so I can have a look. It may be a lot of things from improper can alignment to poor enrichment etc... I didn't see the videos

i can send you pm tomorrow and would be very glad if you have a look at it

[fatiii]

why do you say "RS2" and then say the engine is a 3B and not an ADU?

You have a serious miss on at least 2 cylinders. Could be plugs, coil packs, injectors, who knows.

Can't help you too much because of VEMS.

I know at the end it wouldn't start. With Motronic it would be because the Motronic wants > 13 RPM before it will trigger the fuel pump relay (which powers more than just the fuel pump). J17 Fuel pump relay info: http://forums.quattroworld.com/s4s6/msgs/22583.phtml Not sure if your VEMS is set up the same way.

the original engine of the car was rubbish. i preffered this motor because it was the only choice here if i try to start the car with matronic would it help me to solve the problem? there is no problem on fuel pressure or on ignition. does cranc sensor or camshaft positon causes this problem?
