Chevrolet Suburban 7.4 1999. problems with immobilizer
 

Hello dear friends!
I'm from Russia, I write to you through an interpreter, so ask forgiveness for the errors in the text!
We bought the engine box, wiring and computer on the Chevy Suburban. The body itself and the immobilizer unit has long sold for scrap.
We have established on all Nissan Patrol is now the engine starts and stalls in a second.
I tried to find a bunch of ECU + Immo + keys in Russia, but could not find.
What can you advise me? Is it possible to start using the emulator IMMO?
I will be glad for your help!
