i have a 1999 civic ex and i am planning to swap in a 2000 ls motor soon. what kinda ecu should i get because i heard i cant use the 2000 ls ecu becasue of the immobilizer????

If you plan on getting the motor BAR certified you can swap out the guts of the ecu that the LS comes with(i dont know what it is) with a b16a2 ecu and it should run the motor for the BAR test.

If not, i believe 99 LS did not have the immobilizer.

1999 ls ecu does not have a immobilizer but its obd2A and my civic is obd2B. would it run normal if i got a jumper harness and ran a obd2a ecu with my obd2b motor?

I have no idea.

Immobilizer can be removed but a CEL will always be on which wouldnt work if you plan on BARing it, if youre not, then do a search for the removal of the immobilizer.
