if you bought a b16a swap you should have got the b16a ecu with it, and its set up for vtec you'll just have to modify your harness and hardwire it into the ecu, sounds complicated but its really not that bad, i have a turbo b16A1 crx with a 50 trim and its awesome love the car vtec works fanntasstic

oops didnt see that it was an si, should just be plug and play basically ive never heard of chipping the ecu to run vtec if you have the b16 ecu its already set up for it

u can chip the ecu to drop the vtec engagment points, set rev limits,disable certin sensors,actviate 2 step and reprogram your low and high maps.u can control bigger inj,reprogram the bin to run a differant map,
