Lexus afm and 550s

He doesn't know if it's rich nor lean, that is speculation because he doesn't have a wideband.

Speculation or not, it isn't rich nor lean from the Lex meter and the 550's. Unless he installed wrong some how.

^ This. The whole "resetting the ECU to fix problems" thing needs to die.

Good luck trying to kill that one.

No, I'm agreeing with you. He's just assuming the car is rich because he's read that lex/550 goes rich.

He doesn't need a WB to determine mixture. How do you think cars were tuned/repaired before them? They're a relatively recent development you know. Few professional mechanics own one because there's no need.

You must be referring to the spark plug magnifying glass.

Speaking of plugs you guys running a range or two cooler with the your upgraded turbos and boost?

I run stock ND plugs at the Toyota specified gap.
