Thanks very much. Thats kind of what I thought, but I didn't want to go shoving grease where it didn't belong.

So last night my car's rear end clunk got tired of waiting for me to fix it. The inner left half shaft u-joint snapped. So I have my new u-joint here and it has a note saying to make sure it is fully greased. But I pull off the bearing caps and it looks like there is already grease in there. Do I add more? Also, there is a threaded hole in the side and along with the clips is what looks like a little valve. Do I need to do something other than just screw in the valve? What is this for? Do I fill it with extra grease first? Sorry if this has been answered before. I tried searching and couldn't find anything specific about greasing these things. Thanks!

Yeah, I was kind of confused about the purpose and hoped that you folks could shed some light on it. Guess it is just something that is supposed to look cool. I do wish I got to see it in person though.

My friend went to a local car show this week (Hot Rods at the Beach in Santa Cruz)and took a picture of this Z. I have never seen a hood like that, is it something custom or just obscure?

Oh cool. I didn't see it on my first pass through their site, but I found it now. Thanks!

Haha, right you are. Thats what happens when I am half asleep, I forget that L28s aren't the only motors in the world.

http://alloutofwine.com/cgi/logview.pl So this is an online log viewer that I am in the process of writing. It is very, very basic at the moment, but I will be working on it whenever I get time. Right now you can only look at one variable plotted against time. Soon I would like to have maybe 4 lines on a plot that you can pan left and right on. After that I will work on getting .vex support so you can see what cells MegaSquirt is using at any given point (for now it just says the time and variable value for a point under the plot). After that I am hoping to have some auto VE correction when comparing to target AFRs. The way it works is you can select a file listed on the bottom left, or upload a new one to the public directory (soon each visitor will have their own directory based on IP or perhaps a username). When you know what file you want, hit "Load", select the variable you want to plot from the lower right box, choose colors if you want, and hit plot. I wrote the graphing library using HTML5/Canvas which means that this is for new browsers only (no IE at all). I am not sure how helpful this will be to anyone since there is plenty of log viewing software out there, but I thought I would share in case anyone can make use of it. Any suggestions would be very welcome. EDIT 2: -OK now you can plot up to 4 different variables on the same plot. EDIT 1: -I took out all of the color options to help remove some clutter. -Now you can look at many plots at the same time. Every time you select a plot variable and push the plot button a new graph will generate at the top of the screen, pushing the old one down. -Moving the mouse around on a graph will make the value of the closest point show up in the lower left hand box. You can also choose a MAP and RPM variable to be displayed. This way you can tell what you engine was doing at a particular point.

The biggest problem is that I have run out of time and money. It seems that megasquirt has done a really good job of making this system work well. Moving the injectors upstream would most definitely help, but that will need to wait. The car is very drivable in this configuration, and I need to focus my efforts on the head and exhaust system for now. I had thought of mounting the injectors on the runners, but because of the intake design and the cost of the injector holders I am using I decided against it. I think the TBI type configuration has potential to work very well once I get everything just right. The supercharger will be upstream of the injectors. I wanted to eliminate the possibility of fuel building up inside of it and having a very expensive explosion.

Just wanted to update this thread. I have done a lot of work tuning the car with the injectors in the pictured location. I have been able to stop the fuel puddling and been able to hit my target afr's under most conditions. The idle is still pretty rough, but it doesn't die and fuel doesn't puddle, so it seems to be in a good spot. I will probably leave the injectors in place for a while. I have bigger fish to fry right now and it runs fine.. well, fine enough. Also, as bjhines pointed out, the fuel distribution is not great. However, I wouldn't say it sucks balls either. Cyl 2 and 5 run the leanest, but as luck would have it, MSA put the O2 bung on cyl 2's runner. I will leave my wideband here as to ensure the leanest cyl has enough fuel under boost.

That is an interesting idea. The more I look at moving the injectors past the throttle plates, the more doubt I have. It looks the If I do that it will make the distribution even worse unless I add a spacer, which I don't really have room for. Before I put this together, I had done a bit of research and found people saying that 45 degree angle was good. That is the angle the injector holders had when I bought them, so I didn't really thing about it. I can definitely see how moving them upstream and angling them more will help atomization. Thanks for the suggestion.

I know, Ill just add a Vortex Valve http://www.vortexvalve.com/catalog/all.shtml . That will help, right? Hahaha

Well I have put about 250 miles on this system and it is far from undrivable. It runs rich, but I can see that each time I drive it, it is a bit better, so I guess autotune is doing its job. The #1 issue I am having with this now is that at idle with the throttle plate closed the fuel is sprayed right onto the plate, condenses, and pools. This makes my idle ridiculously rich and I have not been able to adjust the VE table to fix it. I can still drive it, but I will definitely be relocating the injectors when time/money permits.
