Re: RotaryBzzz's Tricks to Make Your Accord Pass Smog Checks
Nice info here 
I have a H22a in a EG civic hatch, its still a D15 on the log book. Is there anyway a clean running H22 would pass as a 1.5 or am I kidding myself?
I'd like to know how much can be done to reduce emissions if you lowered the fuel values on a current engine map and burnt a new chip. I have a socketed P28 so im able to do this but not if its going to make sod all difference
Thanks
