Lawson's 818C

  • Engine
    • Coolant pipes have all been switched to silicone couplers. No leaks yet! They seem to have a better seal than the FFR provided adapters.
    • Did an oil change and have mostly filled with coolant although some bleeding still needs to happen.
    • Installed JDM ECU and ran wiring for AVCS (variable valve timing in Subaru-speak)
    • I got the engine and transmission in the car and everything hooked up. Engine runs well! I was a bit concerned about the large quantities of smoke that came out initially but it went away after 30 seconds and nothing after that indicated an issue. I found out engine codes are quite hard to read with the JDM ECUs because they don’t use an OBDII standard protocol since that’s only a US requirement. You have to get an adapter that supports the SSM (Subaru Select Monitor) protocol which is the manufacturer-specific diagnostic protocol and works on all Subarus globally. The Torque app supports the protocol if I can find a bluetooth adapter. Thankfully, I was able to borrow a snap-on scan tool that did the trick for this weekend. Only code was for rear O2 sensor (Which I don’t have). Hoping I’ll have it back together soon and drive it around a bit.
