Flying by to say that after about 10 months since I bought the car and roughly 5 since engine swap began, it is finally on the road awaiting registration paper (local bureaucracy thing). I had some issues as is with any big work, but nothing that's related to putting CTH in previously CAV driven car, things like a leak here and there or mistake during assembly. It's worth mentioning that I have final stock CAV software ver.9971 Engine managed to complete all readiness codes. Pulls like it should both on compressor and turbo. Anything that I logged was within specification. No overheating, no undercoolling, no exhaust noise, no misfires, no smoke, fuel consumption within expectation, no rattles or knocks. What remains is a bit lumpy idle on cold weather starts due to NGK BKR7EIX plugs. It did noticeably improve after running full 45 liters of fuel with pulse gt injector cleaner which I opted to run because injectors were used with unknown past. Second thing is I had twice p0420 catalyst system efficiency below threshold (mind you, after successful readiness). At first I thought it's an exhaust leak on cheap FA1 clamp, but no, second error was with pipes done by the book. Right now I'm thinking it might be aftermarket diverter valve with flat orings, but that doesn't fit the picture much. Alternative suspect is secondary O2 sensor with 170'000kms on it. My Renault Megane mk1 also had O2 trolling around constantly but not setting codes so I'm willing to guess a lazy sensor can be good enough for self-test but not for normal operation. Took me for ever to get around making a log of O2 sensor, I have about 2 hours of it but as luck would have it, with lackluster cheap scanner instead of VCDS. I'd like to post a photo, but there isn't any obvious CTH feature to show when it sits in engine bay.
