Anyone been running on the stock v5/6 ecu for an extended amount of time without any issues?

I'm thinking about upgrading standalones and running my J2 ecu in the mean time. I'm just hesitant with the lack of knock monitoring.

Well I just installed my JDM STi J2 ecu and I have to say it runs like absolute poop compared to my old custom tune that was on my Apexi PFC. Hoping that it smooths out after putting some more miles on it. Also, I wish I could have a commander with every ECU :(

Overall, idle and cruise a/f ratios seem ok. Boost ratios are super rich. When coming to a stop, it almost stalled a couple times and once it actually did.

Well I just set myself up as an ecutek tuner on the old 99-01 JDM ecu's. So I can start offering remote tuning on these if interested. I am pretty sure these are the version 5/6 Sti, WRX, forester and legacy turbo vehicles.
