I got the cable in today but I am trying to figure out how to get virtual box to forward ports so I can use the serial adapter. Anyhow, I hope to get some readings once I get over this last hurdle. Should have just bought one with a gauge, but I wanted the better range of readings.

I am trying these links to install the driver. This open source driver installed properly over the one I installed from the manufacture.

Now I am trying to get my virtual box to boot so I can test it out.

I have wasted enough time trying to get these serial ports to forward through virtual box. Screw it, I am going to use bootcamp and just install windows in another partition. oi.

Well I have spent a lot of time getting the pc sorted out today, but I think I have a short somewhere in the system. For whatever reason I may have burnt out a fuse. I was going to save it till I was done with the O2 tests, but I think I need to redo all my wiring now. I know my code 54 setup got mangled by the first painter, so I think that is the culprit. I will double check everything to be sure though. Sigh.

Seeing this question is a bit of a worry... you should do some research on general engine tuning theory if you need to ask this.

You dont "take" EGO readings.
With a in-car installed wideband, you drive around as per normal and make sure the EGO readings are appropriate for the conditions at that moment in time.
Dont log the EGO data (its meaningless unless you also log everything else the ECU is doing).... just watch the gauge.

I Have a book on engine tuning I will crack open once I get the gauge running. I think the gauge may be what keeps killing the car so I need to check it's wiring too.

Fuses look good, but something seems to drain the battery. It all started when i hooked up the aem, so i will start there.

EDIT: I removed the gauge and everything is back to normal. I was sharing a spot on a distribution block to power the aem and another device. I think this was overloading something somehow. When I would hook up the computer it would seem to drain the car shortly after. I am busy with work now, but I will try to get up early in the next day or few and sort out the wiring while it is cooler out. Sucks being stranded. My Z has been at the body shop for over a month, and I don't want to drive the alltrac till its done. Luckily I work from home.

Also I found that I still have the plug for the LEV sensor on the 205 harness, so rather than fooling this like I most usually do I want a working water level sensor in case I ever spring a leak in the intercooler system.

I took apart my dash wiring solutions. Looks like I had two hot wires sharing a port and one did not have a ground. I need to get some components but I am going to setup a distribution block for grounds to make a more reliable point. Hopefully I can get this all sorted this weekend.

So I started on my wiring. I am not sure what the official name of this would be but I will call it a ground tree.
Rather than the twisted mess I had before when determining my wiring solutions I am now at the stage to do everything proper so it can be finished. The plan is when I say I am done and I install the dash, I do not plan on removing it again. I will need to hook up a few things then I can put this all back together. I need to wire up my water temp gauge, and I need to decide where I am going to mount the power distribution block and switch for ignition power under there. I might need to see how much room the radio would leave me then make a bracket underneath. I also want to add a second power point in case I decide to use it for something like charging ipod, or running my wideband, which i am going to install a car plug onto from an old cell phone car charger.

Like the tree. I will probably steal that idea when I start wiring up my new gauges.

Dont....

If any of those draws a decent amount of current, youll end up with a voltage drops on the other cables as well, and introduce problems.

What is the difference of using this as a ground over placing a few grounds on a single point on the chasis? Are you suggesting every ground have its own spot behind the dash?

So I stripped all the extra stuff out and am back as my normal baseline before the short issue. Now to fix code 54 again, then I can slowly move to each additional item.

Because the chassis acts like a friggin huge cable which has very little voltage drop across it at large currents.
One point/bolt with many cables to it is fine, as long as they all have good contact to the chassis & bolt.

What youve done is fine if its for some simple low-current gauges (dont do this with a WB02 gauge!), but its not a good idea to do it with anything else on the car.

Ok thanks. That makes more sense. So I will reserve this for my low power things, like code 54 ground and mechanical gauge light bulbs

Speaking of code 54, I have been taking the whole circuit apart and trying to figure out why it is not working.

I started testing things, since one thing that never happened was the lightbulb never came on.
So I tested my bulbs, and all work. Then I tested my relays and they work. So I hooked things back together and I noticed that the INT wire from the ecu is not working as it maybe should. When I replace INT with a ground the relay works. So I need to figure out what INT needs to do in this equation and I might resolve the issue.
EDIT: I just looked at the 205 BGB and between the oem relay and INT is EA1, which I is earth/ground. I think I run a ground between these it will solve the problem with the relay.

I also ran across this page that I will go thru and see if there are any hints.
