So I'm revisiting the same problem I have yet to find a great answer to. Passing emissions and tuning an OBD 2 vehicle. Figured I would find out how ppl here on honda-tech are doing it. I know the right way to get the tuning done would be down convert to OBD1, chipped ECU, and chrome/hondata/neptune/etc. but that's just not an option when the time comes for emissions (yearly here in PA).Additionally I know that most piggy back systems are inadequate for proper tuning. So what do you guys recommend? How are others passing emissions? I need something that will allow me to at LEAST tune for compensation of lower compression pistons.
Preferably I would like to not have to rip off turbo, manifold, injectors, etc. each year. So far the best idea I have is to run OBD 1 during the year and pick up something like the AEM FIC for passing emissions. Pull the wastegate spring and just have a light tune for larger injectors and lower compression.
Comments, suggestions?
