What Do I need
 

Hey guys, car is almost done and now I need an ECU.

First things first, my harness is SHOT.

With that said I wanted to get a used (with a harness) e6k or e6x and wanted to know what im going to need. My car is also non seq and all my emissions are removed and the OMP.

Any help would be great

thanks

What kind of car?

The EMS's out there will be able to run the engine as if it were on an engine dyno, spark, fuel, timing, etc.. So if you need something that will run the engine they will work, and they run the fans, ac, etc..

is it a complete replacement for the ecu in the car????as in ill be taking the old one out and pluggin directly into the new one or no??
