im doing a 13b swap on my fb amd i was wondering what this is in the picture below. if you cant see it let me know i could make it out to an extent but my moniter is messed up.

 

Ecu, the brains of the stock fuel-injection system. I might be wrong but that looks like an N/A ECU from the numbers.

 

Where did you find it? Was it in the first gen or the the 2nd gen? We need this kind ofinfo. If it was under the storage bin in the first gen it is the stock ECU yes

 

Thats the engine computer for a 88 non turbo...

 

dam ur good 82transam, well i dont know i was helping pull this motor and i had to leave when i left a guy who was helping cut everything that could have been cut and just handed it to me, thanks for all the help i thoght that the cpu was the engine controll center and this was something else. thanks for all the help,

 

Yep,S4 N/A ECU.

The 326 and 327 are basically the same unit,covering the 86-88 models.
The 326 is used on the early S4's,with the 2-3 ohm injectors and an external resistor block.The 327 is used with later cars that have the resistance built into the injectors.
Either ECU will run either engine,provided you come up with the correct,12-13 ohms of total impedence.

I hope you get everything you need for the swap.Honestly,if you didnt already know that was the EFI computor,you might have some trouble ID'ing all the rest of the stuff youll need for the swap......

 

probubly but i just got a lil confused because the wiring digram labeled it as the egi control unit, and chances are that i will need to get some more parts providing that the original donor car hasnt been smashed yet.
