I've dealt with older vehicles in Illinois & it wouldn't fly.
Obd-II cars just get scanned for readiness tests here now.

Mega- HC's at low R's.
What kinda testing exactly there , do you know???

I.E.;idle /hi idle, dyno testing etc.

This is for an LS1/A4 swap into my 91 RS.

Well the car should be OBD-II scanned...where I live they are as likely to sniff it since it's a 91 RS as they are to scan it. Friend put an OBD-II set up in a car he swapped an engine into...they refused to belive it was actually OBD-II and sniffed it.

Sniffed at idle for H/C limit is 220 PPM

No rollers, car will get sniffed warmed up.

Not too worried about OBD-II scans.

It would surprise the hell outa me if you could get that cam past a sniffer. I've heard 224 on 114 is about the limit. That's what I have, but they just do the OBD2 scan here. I'd show them what you have under the hood and try and get them to do the OBD2 scan.

I've heard of hot cams with slower ramps and nearly the same exhaust duration passing with a 112 LSA

That cam should pass the sniffer test with tuning. If I understand you correctly, testing in your state is at idle speed with no load only?
Reduce ignition timing and lean out the IFR table in the lower MAP values (25-50kpa). Lean out the IFR until just before lean misfires occur. You'll be amazed how much fuel you can pull out and still have a running car. I've seen cars with much bigger cams than MMS's229 pass the CA test. We however, have rollers and only test at 15 and 25mph.

Good luck,

Richard

I just faced off against the sniffer:
220/220, 564/564, 112

Failed the first test but passed the next....to pass I:
1. Tuned car w/ls1edit
2. added 12 bottled of dry gas (methonal) to 1/4 tank 93 octane
3. changed oil
4. cleaned oil catch can
5. raised the idle tp 910rpm


...It all really depends upon the required emmissions fo rthe test


my hydrocarbons were high; if the hydrocarbon limit is 60PPM then that cam is not going to pass...

if hydrocarbons need to be only 70 or so, you may pass...

Hello,

I saw your post and thought I'd give you a little hope. I own an automotive repair facility in Chatsworth, Ca. We have some of the most astrigent emissions laws here and experienced a pretty cool thing the other day.

I think you guys are also a loaded mode testing state. But I heard they poo-poo canned the program up there?? Maybe my info is wrong.

I had a factory 2002 ZL1 427 Cu.In. Camaro in the shop the other day for a smog check. And guess what?? It passed with flying colors. The cam is around the 230's @ .050 and has to be around 110-112 L/S, full length headers, C5R block and heads, and an ZO6 style intake. The thing idles like an old street racer (rough idle), but passed squeeky clean. If you have LS1 edit, I can send you the factory file. It may give you some programming idea's. Just lemmie know.

dude, send me the ls1 edit file. im gonna try and get a 224 112 to pass and i'd like to see the tune. also, how did the car pass visual

Scott

John, can you also send me the ls1edit file.... I'm up for testing as well and would like to update my tuning since my top end set up is close to what you described above. Thanks!

John,

Please send me the file because I know I'll be fighting the emissions battle here...and probably on both fronts sniffer PPM limit is 220 and/or OBD-II scan. Friend of mine installed an OBD-II system in his older car and the tester refused to believe that was possible so the car got sniffered instead of being scanned. I have to cover it both ways.

Where in Carolina do you live? I asked a guy that has done my inspections before, what the test he performs is. He told me all they do is the visual and the OBDII. So I am pretty excited about getting a cam for my car. I am thinking of a 228/228 .588"/.588", 114 LSA. I think that this cam will pass with good tuning.

In Gastonia near Charlotte. The correct way would be visual and OBD-II scan...some of the testing folks in Gastonia pretty much do whatever they please...if they don't like performance cars.

Of course one can always get inspected in Charlotte...

Hi ya John! Welcome to the board
I've thought about how that ZL-1 passed am still impressed. One thing you should also mention is how the fuel trims were pegged at +25%. I think that's gonna be key to passing any smog test with a rough idling cam. Gotta lean out the engine until just before missfires start to occur.

Good luck with your smog tests guys.
