What ECU for LS swap in '99 Civic?
whats up fellas, been a while since ive been here,ne way im thinking of trading my 93 talon for 99 civic si. the friend im trading with blew the b16 up and got a 94 ls motor for free and put it in it, knowing what i know i thought the engine harness had to be changed but he said everything hooked up but it need a ecu, what ecu should i run for it, i was thinking a p74 but i havnt been around a honda in a while. how hard will this thing be for me to get running. the talon runs and drives like new with no problem and a nice body, the si is clean inside and out and miss my hondas. thank u for any advice

As long as he kept the original 99 Civic Si engine harness, I would get an OBD2 P75. And the P75 was available in OBD1 and OBD2. Know that I think about it, being a 99, you may need a OBD2B ecu.
thank u for answering me, i think the ob2b is correct bc its for manual transmission i believe, i got a friend sending me one so i can at least get the si running, im kind of skeptical about trading as my talon runs and drives like new
