Not exactly today but over the last few weeks, I have got all the parts from my White '15 transferred to my Red '15. I have also picked up an SCT X4 and a GH tune. Started messing with FMods to further modify my Sync3. They have a method that does not require disassembling the APIM any more. After running a couple tanks through, I plan to datalog and get in touch with GH. Have a couple questions and requests. It honestly doesn't feel much different. Not as noticeable as I had hoped. They said that datalog is not needed but, I am hoping for more of a custom tune than a can tune.
So after getting my tune installed, I started having issues with the car breaking up at about 45-65 under heavy load. Occasionally, it would do it from a 20 roll if I laid into it. I have MSD coils and they are 13 months old. This is about where I have heard of people having trouble with them. I had a P0303, P0300, and P0316 code. I have not changed plugs since I got the car so, I had no idea the condition of them. Today, I pulled all of the coils and plugs. Being lazy, I started on the front then moved to the back (in 1, 2, 3 order). Why I have no idea because 3 was obviously the problem cylinder. Plugs didn't look terrible so, I cleaned them up and gapped them to 0.026. Last plug I did (#3) I pulled out and held it up to look, it looked pretty good. I flipped it pointing down as I went to grab my gapper. I heard/felt a *tink*. So I looked at it again. Pointing up it looks fine. Pointing down the center ceramic isolator is broken and it slides down to make contact with the ground electrode completely shielding the gap. So either my spark was occurring way deep in the plug or inside this new ceramic shield. Unfortunately, I am on duty and only have Napa, Autozone, and Advance close enough to use. They had limited selection so I went with NGK 6510. I pulled all the plugs again, gapped the new ones to 0.026 and reinstalled them. I also swapped #2 and #3 coil just in case I had 2 issues. I cannot wait for the drive home in the AM to see how the car feels on all 6 cylinders!
Not the SHO, but went to a car show today lookin for 3 row suvs for the wife. They had a small owner section in one corner and I found a Factory Five GTM. The first one Ive seen up close. The desire to trade the sho for a minivan and build one of these is strong.
