General 97 Non Eprom to 95 Eprom Swap

[Slo2gn]

I recently got my hands on a 95 eprom ecu had some cap work done and resistor work as well.. I have a 97 GST that had a 97 Non Eprom .. Long story short I installed the ECU and did the plug swap and my car wont fire up it just turns over.. I checked the fuel pressure it has good fuel pressure while cranking I am getting spark and just bought new NGK BPR7ES plugs and still have the issue persist.. I did a quick google search and came up with the same answers also noting that some have to invert their CAS also some mentioned changing the injector signal at any rate I have a triangular CAS I dunno if i am supposed to invert it. I also have no idea on how to change the "injector signal"

Please help thanks!
