will a usdm ecu work on a jdm motor?? i have a 96 jdm prelude motor in my 97 accord and the ecu that came with the swap was for manuals (i left it auto). i've found a couple 96 usdm A/T ecu's but was wondering if it will actually work on the jdm motor?  

hm..let me rephrase this now... will an h23 ecu work with an h22 motor?? both are 96's..my car is automatic..and from what i've been hearing..the vtec models for that year only came in manual...true?? my motor is a jdm motor.  

no you cannot use the h23 si non vtec ecu on the h22 vtec you reaally need to find an auto ecu or convert you car to 5 spd  

also no not true my gf just bought a 96 prelude automatic h22 from the original owner.. and any 92-96 h22 ecu will work on your swap as long as its for auto and vtec
