i just messed my self over. so i was doing ecu swap and i replaced the emobiliser chip i soderd the old one on the new one. but now the car wont crank or star. is it because i disconnected the possitive battery for so long ? i need the car to get to work and i just screwed my self over . the fan just runs high and thats about it .

Disconnecting the battery will cause no problems with the immobilizer. This chip soldering is a bit outside of my knowledge base, but I suspect that is the source of your problems.

if i buy a new ecu were can i go get it flashed

insame1

the dealer for sure but a tuner like eurocharged might be able to help you also.

zuzu_pali

even after swapping the emobilizer ? do you know if you have to get it flashed even if i swap the emobilizer? i kind of know i messed up because when i tried to put the emobilizer back on the original the car still would not start . just the fan turns on

hey im going to stop bothering you after this i swear. but if i buy this http://www.ebay.com/itm/141850896689?item=141850896689&viewitem=&vxp=mtr
do i have to program anything ? or i should be fine because everything is programed together ?

zuzu_pali

please reply so iknow exactly what to buy. so if im buying the ecu with the key what els should it come with so everything can be perfect?
1x ECU/ECM
1x Key/FOB
1x Door Lock
1x Trunk Lock
1x Ignition

1x Steering Lock
?
or can i just use old key to open car and new key to turn on car and drive?
is the steering lock important ?

Rudeney

I can't promise that those parts will be plug-and-play. Also, without the matching instrument cluster (or a new virgin cluster) you'll lose the odometer.

zuzu_pali

meaning the cluster wont work at all? dam everything is connected , its like i hit a brick wall every time something is stopping me .
but when you mean odometer nothing will function on it?

Rudeney

Cluster will work, but odometer will show "-----" .

zuzu_pali

if i buy all of them do i have to buy the stearing lock? is that important ? because i just wanted to use my other keys to unlock and lock door , and new keys i buy to turn on car

insame1

keys are programed to the ecu

Rudeney

The EIS, instrument cluster and steering lock are all tied together. My knowledge of this is more "official" so I can't help much when it comes to cobbling together used parts. Many of these are configured so once they are initially coded to the vehicle, they can't be moved to another vehicle. Of course where there's a will, there's a way. For example, there are tricks to swapping out instrument clusters, such as swapping the EEPROMs or even zeroing the miles on the donor's EEPROM. None of this is easy, and not very well documented, but "possible".
