I'm running JDM Legacy EJ20X/Y heads/cams on a USDM Legacy EJ255 ECU and loom, with AVCS working, meaning the USDM cams must have the same slots as the JDM Legacy EJ20X/Y have (so the JDM Legacy EJ20X/Y cams differ from for instance JDM STI cams regarding AVCS pick-up).
That would have been great to know when MZM was working on my WRX with EJ20X swap that that couldn't get to run correctly without the proper ECU.
