b series ecu

k my friend just got a swap in his 5th gen sedan with a b16a2. the problem is that the ecu he got was for an auto. he wants to know if he swaps in like a sohc vtec ecu, if it will work for now then he can chip it later. or could he chip the auto with one of those chips they sell on ebay, i dont know if they work for the auto ecu. would a gsr ecu work on the b16a2. or if you guys could just tell me what ecu will work and what are the problems with each of them

Use a pr3 or pwo for manual transmission only...no shortcuts.
