1. Since i have a 99, when i go to emissions testing they just hook up their computer to my ecu plug under the steering wheel and in like 30 seconds its done. To tell you the truth i cant even remember if they turn the car on. Anyway, with my DSMLink and 95 ecu, will they still be able to hook it up to that plug..or will they have to put my car on the rollers?
2. Will a walbro 255(low pressure) pass emissions? I was told it would not but i dont understand why.
3. My dad told me that if i put rubbing alcohal in a tank with little gas that i would lower my emissions big time. Anyone tried this or no if its true?
4. Alot of people have said they passed emissions with cams, big turbo, 660cc injectors, etc etc....but if they just hook up the comp to the plug in my car, do i have to even worry about this? if the car is tuned right it should pass correct? I guess my only worry is that since the car will have a 95 ecu that they will have to put it on the rollers.

in IL, on 96+ OBD2 compliant vehicles if the OBD2 port is non-operational, the Vehicle will be issued an automatic FAIL. Smog test is for 1995 and older OBD1

make sure you have a cat or something that looks like one though, they check that with mirrors. Also don't reset your ecu right before you go, you'll have to go back and do it again. As long as you have no trouble codes, you're fine. Gotta love OBDII!!!

You'll pass just fine. I passed with 550 injectors, running lean as all hell. They don't sniff or anything, didn't even look with mirrors on my car, DSMlink had no problems.
Before I went in, I walked in and told the guy I had an aftermarket ECU on my eclipse, and even the Mitsu dealership couldn't plug into it. He says their machines are a lot better, but if it can't read it I will have to replace it.
Read just fine...passed...$26.50, thank you very much.
Gonna try it again in 1.5 years with no cat and see what happens.

Rubbing alcohol is 70% isopropanol and 30% water. Isopropanol burns really poorly, gives off tons of smoke, and the water does not combust or compress. You'd be killing your engine or cat by doing this IMO.
What I'm sure he meant to say was to use pure grain alcohol (ethanol) like Everclear, which burns with very few emissions.
Emissions don't matter at all though, unless you're getting a probe stuck in your tailpipe with the engine running.

Just go see if you pass before you take anything off. Worst comes to worst you pay another $14 or whatever it is. Just got my emissions stuff Friday so I gotta do that to before I get rid of all my cats and put on the downpipe. -Dave
