ok thanks guys, honestly what happened is, i took the sentra to a shop to have it done, two months after they got all the parts in they hadnt even touched it so i pulled out, after all the sentra was my only car then. So i ended up having to buy the parts from them for 2000 which is wayy over priced and now i have a friend thats done these swaps before, i was kinda wondering which ecu is better to use, and since the engine harness on the sr20ve was all there i figured id use that ecu
