Ecm

Just wondering if a ECM from a 90 Civic Hatch (1.5 ) will switch to a 90 Civic SI Hatch (1.6)....thanks

No it wont, the 1.5 is dual port injection, and the SI is multiport.

the si had a pm6 and the hf has a pm7 i think and how those are the ecu's you want for a 1.6 si or a mpfi swap.

Thanks for the answers...just trying to see if I had a bad ECM....Pappy
