how daily drivable is that? emissions possible?
Very daily drivable...I daily drove it for a few months.
Emissions....I guess you could run it to pass smog, but I would recommend staying with a honda ecu / harness if you care much about it. Little bit easier and less headache. S300 is a good choice for serious tuning.
I would say that SDS is a little more "hardcore" and not for the guy that needs it to pass smog instead of making all the hp/tq. Again, as an example, the program isnt designed to run an 02 sensor all the time....versus a honda system.
Does that make any sense?
