I have a spare '01 GS-R ECU from when I did my swap and now have someone with a '99 civic putting in a GS-R that needs an ECU...what is involved with making my ECU work for him? I have not seen the car yet but I would assume that it's OBDIIb ('99 and up?) but not sure what do about the immobilizer (I think only on the 2001's?). Any suggestions? Thanks.

 

All 2000-2001 US Integra ecu's have the immobilizer.. It can be removed by companies such as mine..
