2013 Scion FRS April 2013 Build date. Had P0018 Code. Replaced the timing gear. CEL stayed on Was permanent. Dealer said I needed a new ECM and to save a few bucks I could buy one on my own and put it in. They said I needed SCION part number SU003-04674. The original ECM is Subaru HE 22765AC813 112700-1235 12V DENSO. I called SCION parts and asked for the ECM... it was ~$500. I didn't know based on comments here and elsewhere if the ECM would fix it or not, and didn't want to lay out $500. I went to the junk yard and bought an ECM off a 2012 Manual SCION... HD 22765AC803-112400-4846. It started but CEL stayed on... Junk yard got that one back and i got my money back. I called Subaru parts and asked for a replacement for HE 22765AC813 112700-1235. They told me that part had been superseded by CW 22765AG511 112700-6501. I got on ebay, found one, and put it in...it works... Not sure what the difference is between the HE xxx and the CW xxx, but the Toyota / SCION dealer told me they had done upgrades to the ECM. Scion could not give me the upgrade part numbers printed on the ECM, had to go to Subaru for that.
Hopefully it sticks and keeps working/keeps me in business, and hopefully someone else finds this helpful...

Glad you got it working.
This is probably a bit too late now, but I'm thinking you were looking for similar information. I just came across this in another thread. I knew I'd seen it before, I just couldn't remember where.

If your solution ended up working out permanently, it would help the community if you could list the CAL ID numbers of your original ECU and of your replacement ECU. That way it can be documented as to what CAL ID works after the repairs that were made by the home mechanic who has access to the proper hardware and software so that they can reflash their own ECU. This would prevent the requirement of purchasing a new ECU.
By the way, what are you doing with your original ECU, if I may ask?
