1st Gear shift -> Engine light Flashing

brainrain

Thank you for your response.

I use SP98 of ESSO ( I think for you it's 91 or 93 octane). Maybe previous owner drive short trip. The owners of the 370z in Europa does not drive often due to the high price of gasoline, we drive it just for fun or track from time to time. I have another car for daily drive (diesel car)

But when I drive my Z, I take this opportunity to drive well. So that I understand I can remove driving with putting engine good load.
According with Spooler, I can also install oil catch cans but it's too expensive now (shipping costs are high because of COVID).

Do you advise me to remove the knock warning light by Ecutek ? Do you agree with my mechanic that I can destroy the engine if I go full load ?*
A t the moment, the Knock warning light only blink when I go full load on 4th gear. But after several minutes, I no longer have this problem.

According to this post (and my mechanic says), it could also come from a bad software:
