Hi there, I did my conversion recently and I was stuck with an EWS ECU with no key etc.
I asked a few mechanics, posted on the forum and did some research. One famous mechanic also told me to 'campak dalam sungai' (he was referring to my engine) because it was EWS version.
I was told my only option was to get a non EWS ECU and harness. After multiple opinions, that was what I did. My mech sourced a non EWS ECU and wiring harness for RM1.5k and that solved all the dramas.
Just to share.
