Failed emissions today

RE: Failed emissions today
you could try to burn all your fuel down, so your pretty much empty. then RIGHT before you go get inspected put some 85 in, the fuel will burn a lot faster and hopefully more completely. BUT you have to be careful to NOT build boost(which they shouldn't at testing) or at least any sort of load. if your running in vaccume and part throttle you should be able to pass without causing any detonating.
can you tune your engine yourself with the tools you have? it sounds like you can't otherwise it would be easy to pass.
one last thing, i have had UNCONFIRMED reports of people stuffing steel wool and fiberglass in their exhaust to help pass emissions, the theory is that the packed exhaust will slow the unburnt fuel, then heat up and burn the rest of the way, like a cat.
try at your own risk

I thought of something else...by a "perfect" a/f ratio did you mean stoichiometric, or perfect for making power at altitude? Because those are two different things. Actually, you shouldn't be at 14.7:1 anyway, you should be richer than that. That's how car engines work. But i'm rambling.
I still say turn up the boost, if all things (like fuel being squirted) remain equal, more air with same amt of fuel should give you a more emissions-friendly ratio.

RE: Failed emissions today
ok i solved my problem. im changing my cars registration to a different county in the mountians where they do not require testing. they pluged into my obd2 port and the tail pipe. ya i can change my a/f ratios with the AFC but i dont wanna screw with that, i guss i could put the stock injectors back in but that again would mess with the tune

Just a thought...... Run the highest octane fuel you can find get some irridium plugs (or any top quality plugs) lean your car up a bit... not too much that it blows but just enough. If your running a BOV go put a DV on it. The lesser the octane, the less flammable/explosive. The higher the octane, the more fuel gets burned. Thats what i'd do (worth a shot).
