Thanks.

I found a few threads here and on rennlist

Start engine, idle cold for approx. 2 min, 10 secs.

Accelerate to 20-30 MPH, Maintain steady speed for approx 3 min, 15 secs.

Accelerate to 40-60 MPH, Maintain steady speed for approx 15 mins.

Decelerate and come to a stop. Idle in gear* for approx 5 mins. (manual in neutral)

don't exceed the max speed in any step or go over 3000 rpm or you need to start that step all over
Apparently the steps are cumulative and can be done separately (YMMV)

So far I have gotten the catalyst to reset, now just the evap is not reset.
From what I have read, you need to have between 1/3 and 2/3 gas in the tank.
I am pretty empty right now. Gonna put some gas in and try the drive cycle again
