im not saying your wrong it just sounds kinda strange to me. i don't have to mess with inspecitions here so i haven't ever delt with any of that.

 

thius was the only way i could figure out to get them on here. i'll just no put them up there

 

No emissions testing down here in florida to even worry about for me. That's how i beat it.

 

Thanks

 

Buy the guy a 12 pack and give him $100 and you will pass.

 

There is some stuff you can do to pass the test:

1) Make sure the ignition system is in good working condition. Do a tune up. Check and replace if needed PCV, EGR, fuel filter, air filter. Get rid of your K&N, and stick in paper filter. Oil from the reusable filters can drive up the emissions.

2) Make sure your engine is equipped with a working catalytic converters. HiFlow type sux. You want two inline per pipe, as per factory specs. So this means a down pipe swap.

3) Retune your ECU, 14.7:1 is the ideal (stoichiometric) AFR for the gasoline. Both, running rich and running lean will bump up the emissions.

4) As long as you're tuning, retard your timing by 5 to 10 BTDC. The decreased thermal efficiency of the engine will create hotter exhaust gasses, which in turn prolongs the burn and also helps the catalytic converters to operate at peak efficiency.

5) Increase idle speed. 950 rpm sounds just about right for our engines.

6) Increase the ON temp for the electric fan to 200 to 210 degrees.

7) Add alcohol (this is also available as gasoline anti-freeze) to your fuel tank. Start by putting twice the recommended amount for the anti-freeze. Alcohol introduces additional oxygen into the combustion process, ensuring a complete burn.

No. Retarding timing creates hotter exhaust gasses due to decreased thermal efficiency of the engine, prolonging the burn and helping the cats operate in their peak efficiency.

Combustion of air and fuel does not end inside the cumbustion chamber. Catalytic converters suppose to burn the unburned. If you have no cats, you often get a flame.

im sure everyone appriciates the advice and all.. but the whole point of trying to pass is that we DONT have catalytic converters... otherwise we wouldn't be here in the first place

 

i realize how the internal combustion engine works but if yoiu dont have cats and your trying to pass an emmisions test then you would want as much gas burned up in the combustion chamber as possible. there for retarding the timing would push more unburnt air fuel mixture in to the exhaust piping.
