Emissions tuning
Hi guys,
I need to pass an idle and road simulator emissions test in Vancouver, British Columbia. Any tips on tuning with LT1_Edit to minimize my readings? I would like to make sure I pass well the first time. I have no EGR and a cc305 cam with ported heads. I have header leaks also....
Thanks!

Check out my thread:

Also, your header leaks could cause your problems, as you might be getting extra O2 in your exhaust, thus causing the O2 sensors to read lean, and the pcm to add fuel. That will cause your HC's to skyrocket. So, how do your BLM's look?
If you don't want to or cannot fix the header leaks, you might want to lock your car into open loop mode and run a lean program, 15:1 or leaner. That in conjunction with the info from the thread I pointed you to should get you to pass.
