That engine looks massive! I'd love to hear that thing run!
Well, I'm TRYING to upload a video to YouTube, but everything is fighting me tooth and nail. First my system was crashing HARD whenever I would try to render the video. That eventually healed itself, apparently. Then Comcast dropped out all last night until I just gave up and went to bed. Now I'm trying to get the video up into YouTube and their site just hangs and kills my browser as well. Same thing happens when I use another computer to try to do the upload.
I'm about ready to strip down to my birthday suit and go running off screaming into the woods.....
Well, come to find out that the problem trying to upload to YouTube was being caused by my virus checker program...
Anyway, here's a video of the car idling. You will likely note that the idle is very smooth until the coolant temps got to be around 110 degrees or so. Then it obviously becomes very rough and loping sounding. I should have run this longer, because it appears that the exhaust gets rather smoky towards the end, and I am curious about how badly it would get the longer I ran the car at idle. Maybe next time....

BOY, does THAT sound nice! It looks, to me, like the "smoke"
towards the end of the video is carbon buildup being blown out of the pipes.
I'm wondering if it's running a little rich when the coolant temp comes up and
loading up the pipes with the carbon that's associated with a rich mixture?
Anyway, it sounds like it's VERY HEALTHY, and seems to rev very quickly. Must be
a handfull when you get on it!

This video was taken after trying a new tune on the C5Z. Didn't seem to improve much and the throttle actually seemed more sluggish to me. So I didn't rev the engine up very high at all. Just didn't sound right to me. I also cranked up the data log capture since I had the laptop and cable hooked up to the car.
At around to 50 second mark, you can see the overlaid log file captured with HPtuners (but you may need to go directly to YouTube, full screen it, and use the highest resolution of the video) and it shows some puzzling results. Notice the misfire sections. There is something cyclic going on there, apparently. Got to figure out WHAT is causing that....
Has anyone seen anything like that before to point me in the right direction?
Well with my car being in a couple of shops for over two years, I guess it was inevitable that some things would get broken. So the driver's side hood strut got stripped out of the lower catch. I went and JB welded it together, but darn if I can compress that thing enough to get both ends on. How in the world do you do that? I've tried EVERY curse word I know, all to know avail...

MAN.......I've got NO idea how to do that! Maybe put the top portion on and leave
the bolts a little loose, then try to work it up far enuf to get the bottom in.
Depending on how close it is to going on when you install the top, maybe use
a piece of wood and a bunch of protective rags/cloths to protect the finish, and
pry it up from the bottom. I'm sure that they make a compressor for that, and maybe
one of the local parts places (NAPA, Auto Zone, etc) may have them for rent.
Good luck, and whatever you do, DO IT SAFELY! Those things are under a BUNCH
of pressure, and we don't need you or the C5Z getting hurt!

Well, had a guy out of Texas (Bret - BLOWNBLUEZ06 on CorvetteForum) that I met through CorvetteForum willing to help me with the car, and he wanted to be able to look at the tune and scan results in real time using HPTuners, so we set up my laptop via a program called Team Viewer which allowed him to take over my tuning laptop remotely. Only catch was that my car needed to be close enough to my wireless router in the house so my laptop would have access to the internet so he could do that. That meant I needed to get the car as close to the house as possible....
Notice the "high-tech shadetree mechanic hood holder opener" I used. The hood strut on that side got broken in all this stuff, so I had to improvise...
** I can make these available for sale for ONLY $29.95, but you MUST ACT NOW!! **
Anyway, I couldn't really follow everything that Bret was doing, because for one thing the car is do danged loud that I couldn't really hear much of his comments. Plus he is WAY above my pay grade with knowledge of this stuff. But he did point out some things to me. Evidently the passenger side O2 sensor isn't working properly. He thinks that it may because of a cylinder not firing on that side of the engine and that is keeping the O2 sensor from heating up properly. So before we go any further, I need to troubleshoot that problem and try to figure out what is CAUSING that problem. Looks like I might need to buy a few tools to help me in this pursuit.
He also helped smooth out the idle, as best he could with the above in mind.
But heck, I got to drive my car today. Even if it was only from the garage to the front porch and back again. Don't think I want to drive it any further than that anyway, all things considered.
