not strating with new ecu

[rxl]

hello,
got a little prob
today i fitted in a chiped ecu from audi 200 to my s2 3b... wanted some power... the prob is the car does not want to start... whats the prob? is the ecu immobilised or is it just broken?

[rynaqui]

Perhaps the loom is different between the two cars..I'm not sure you can directly swap from different vehicles even though the engine may be the same (3B)

[Pirvu Eugen]

The 200 20v turbo 3B engined...is the same with the s2 3b...should work without issues...I dont know iff is immobilised or not though

[spink]

Ive never heard of an immo 3b.i think its a faulty ecu

Double check the pins on ecu and plug pins arent pushing out of the connector.

Has any car run with that chipped ecu?

did that but no luck... got my ecu about a year ago but never planed to put it in my car... just wanted to keep it as a spare part.. an no i never seen it ever work

Can you hear relay in ecu click when try to start?
Immo should allow the engine to start and kill it after 1-2 sec.
Also conections at ecu...maybe you broken a pin or something?
Try to put eproms in the ecu that starts the car.Do you monitor afr?Is the soft a good surce?Be catreful.

well the weard stuff is i noticed that with original ecu when i turn the ignition only 2 things apear in the dasch(battery and abs) with the chiped one the are 3..
gonna get another chiped ecu at the end of the week and gonna test them..
well i didnt hear a click but wasnt concentraten on the ecu..
