you'd really need to include your rom and a log of the car to get an idea of how well its running.

that's the rom yes, but also need to see a log of how it runs along with knowing what modifications to the car?

The car is driving well, since it is the first experience of configuring the SD, so maybe someone will see errors in the ROM

can't see your wideband readings in this log - you can't tune it properly without that so ideally you'd have the wideband logged as well along with a decent 2nd gear pull in the logs to get an idea of how its running. The front o2 can't really be trusted once you get anywhere near boost - even moved to behind the turbo like most JDM cars I wouldn't trust it enough to tune off it.

I set it up by AEM, the AFR on the fuel card is +-1%. I have a question about the correctness of the "injection time" setting, taking into account AVCS. And there is a problem on cold start, AFR 18:1 and low RPM

on stock 550's the default values for warm up should work fine. look at your VE table though as high idle/cold start will be a different RPM/MAP location vs warm idle. If your fuel is too weak then the RPM cannot rise to target.

injection angle you can use a flat 360 to start you off and make fine adjustments later once your other tables are all dialled in - some excellent information here:
