not so civic

it's a stock block b18b1 w/ 97 b16 head. the motor sees 8-10 psi's. i have a ls ecu now and with the turbo, the vtec controller just doesn't work like i want it to and it's detonating when the cam switches. i've tried playing with the fuel and timing already. ok, so...i don't need to rev to 8 or 9k...should i just get a reprogrammed computer for the vtec? or is there a stock vtec ecu that i could use for single butterfly and a 1.8l fueling? if not, where is a good place to get a reprogram mainly for vtec control? i don't need a crazy NA program. thanks.
