I noticed the knock sensor plug didn't look seated properly. As I touched it, the plug fell apart, obviously degraded from the heat. I would bet the connection was poor for some time. Any body know the plug part number please post up.

MF'er! My ex-man's aren't even off yet!

Shortly tho'...

I got the KS # on a CD that Steve / WeGone made for me. If no-one beats me here, I'll post up by the AM here.

Looks like it is AM...

Thanks Schrade, Found the part number on Rock auto ACDelcoPT308.
Have Patience, Ive Been working on mine for quite a while now. Removing them was by far the worst part of the job.

I missed the step-by-step with photo-snappics???

This grasshoppah is runnin' short of patience...

PT # must be a RA # ??? Different from the edit above?

I finished the installation of my headers / exhaust today and it sounds awesome. I'm very happy with the sound. I think the cats mellow out the sound a touch, as it has very little drone at cruising speed. When you get on it every one around will notice. Not a stealth system for sure. I think the Borla that this replaced had much more drone than this system. I drove it around a bit to see how the exhaust settled in the hangers, one final adjustment and then its time to clean the garage, I think I have every tool I own on the floor.

Yep. I like it. Sounds good looks good.

Schrade · 03-10-2014

Sounds great!

(and you get stealth mode by exceeding speed of sound

(might need new rubber for THAT tho' ) )

If you need tuning help to pass emissions call Rod Dewile at 720-284-4965. He is in Denver about 10 min from your place. I will be out there some time this spring to visit a friend at Wheat Ridge so may give you a call. Rod is very familiar with the LT 5.

Been a few weeks since I posted last, had a relative in town , a ski trip to steamboat and a business trip to LA last week but finally got a chance to spend some more time with the Z. She didn't pass emmisions on the first try, not even close. The car is running so lean now , its causing the HC to be over double the limit. It thought the headers and exhaust would lean it out some but not to this extent. I used an infrared thermometer on the inlet of the Cat and the highest temp I could get them to was about 380deg. New Plugs (ngk FR-5) are white after about 50 miles. I ran about 20 minutes while data logging with DataMaster but this is my first time using so I dont know how yet to post the log. I also have tuner pro but have not figured it out yet either. But it is definitly time for some tuning.

Tyler if you plan on comming to town, let me know as it would be great to meet up.

Looks like I will be there the week of 4 May. I am hauling a car there then going to NCM to pick up my 88. We will leave here 4 May so hope to be there the 6th or 7th. Hopefully I can take you out to meet Rod Dewile so you will have a local LT 5 contact.

Yeah, looks like the plugs are almost blistered. Datamaster logs can not be posted as they are (raw) since the program will only allow a download into Excel or similar file. The spreadsheet can be customized to any parameters.
