slightly old thread that I'm about to bump.
Thought I'd share some of my experience with Ohio.
My Evo is on E85 and does have a high flow cat and the stock ECU.
1. I get P0420 CEL w/ or w/o fouler & recently Evap leak
2. The OBD2 forced inspection pass ECU reflash data didn't work for me, emission computer wouldn't talk to my ECU
3. Drove the car a little over 50miles, still wasn't 'ready'
4. Drove the car 230miles today, periphery bits for P0420 turned off, OBD2 forced inspection reflash is active, no CELS. I will go to emissions check tomorrow and tell you how it goes.
