any SDS users?

what system are you using?
what mods. are done to your vehicle?

i know you can pass smog through closed loop, correct? but do any smog techs say anything during visual inspection?

 

4F or whatever...the one with the included ignition is the only system that is worth it.

smog guys should not even know you have an aftermarket ecu other than no longer having a distirbutor. just get your car tuned relaly good then turn on closed loop and you should be fine.

as for the upcomming Smog Dyno in California i don't think any aftermarket ecu will work on a OBD2 car due to them plugging in that socket into the ECM reader or whatever.

 

i just asked this question 2 weeks ago, do a search.
