Re: b20b problem

Check the dizzy that bolt holding the rotor comes loose and then falls out could be causing your problem

I had that same problem until I got my car tuned. I bought Hondata S100 and got a B20 basemap and now it runs fine.

Re: b20b problem

B20 is 13% larger than a B18, so therefore it needs more fuel and the timing maps are different. I don't know alot about tuning, but I can tell you with my B20 tuned it pulls harder and gets better gas mileage.
