I have a 1990 EF2 Sedan with a 1990 JDM D15B Block. It was originally DPFI but I converted it to MPFI with a 1992 D16Z6 head. I already have the wire harness converted. I bought a ECU with this code:

PM5-A30MB

Will this ECU make my VTEC crack or what?
Thank you guys for the help.

picks of ecu inside and out. Usdm pm5 = no/fail. I think some of the jdm/edm pm5s ran mpfi setups not sure about vtec.
