AFR goes <9 when I touch the throttle
Car has just been upgraded from wasted spark to cops.
Starts fine and runs fine as long as I'm extremely gentle with the throttle.
As soon as accelerate a bit, AFR goes pig rich (<9) and car boggs. Black fumes, so it's really going rich.
Anyone care to take a look at my msq because I can't see anything obviously wrong with it.
I don't think that it's related with the cops though.
Car is a 99 miata with MS3X.

It happens.
I changed a bunch of stuff that would require tuning and also updated my firmware.
I proceeded to spend an afternoon tuning IdleVE and having massive drift. I then remembered a little sentence about how the Gair corrections had changed. I was running my old settings as they had loaded from my old msq. I fixed it and had everything running in an hour.
