Damn, it was in some guys AIM profile a few years ago. Something about "Westminster Bums"

I am very jealous!

Dude, I actually spent an hour+ reading this whole thing. I admit it had me on edge, but I guess it's just fiction in the end. I googled this topic a good bit and apparently it's based on a short story from the 80's. Oh well, it was enjoyable.

Wow Tom, that medical keyboard is something else. I had in mind those keyboard covers you always see when you're at a mechanics shop...only thing is I'll probably have to buy it with a keyboard. Guess I'll just look on ebay.

OK, so who's tired of stopping in the middle of a project, having to go inside, wash your hands, refer to some electronic document or website, and then return to the garage to continue working (hopefully not forgetting what you just read). I know I was, so this simple yet utilitarian PC was the answer to my problem. All these pictures depict is a computer that has been taken apart and reassembled on my garage wall. Internet access is made possible through a data drop pulled through my storage room. I built a hinged keyboard tray with corresponding hinged braces that can be lowered out of the way when not being used. I only have to secure the keyboard to the tray purchase a trackball that will also be secured, and find a keyboard plastic overlay that can be washed to finish this project off.

One final note, of a more dubious nature...having this cable hooked on to your ECU and having the ECU in diag mode kills signal to the speedometer and the odometer. So, if you want to keep the miles looking low you can just leave the cable conncted at all times.

I forgot to mention one very powerful tool in "Collect Data" mode. You can build custom triggers based on the variable values to accomplish logging tasks. Say for instance, you wanted to start logging when the Engine RPMS became greater than 4000.00. You could program a trigger to start graphing Engine Knock and Engine RPMS when the trigger value was met. There are tons of combinations available, all of which conform to a certain scenario.

I used the TMO datalogging software that is written for 91-93 Stealths/3000GTs. This is a Windows app and is mainly navigated by single left-clicks...perfect for the touchscreen.

Launch the app and press connect

The collect data, DRB2, and Review options work correctly, the Describe Car option does not work and the makers of this software folded awhile back so that's just for show

Clicking DRB2 data brings up a window with several important tabs. These tabs show you live stats on most of the sensors that feed into the ECU. Most tabs also let you switch back between voltage and value readings.

This is when the motor is off, but the power to the car is on...notice no air flow value and the battery reading around 12v

Here's where the fun begins, data gathering. This is accomplished by selecting "Collect Data" from the main menu

The data select allows you to choose one or multiple values and capture data based on those values.

This particular capture will monitor engine knock in relation to engine speed. Time is always the x-axis value in these graphs. This would be a great test to see if the engine is retarding timing because of too many knocks, thus robbing power.

You can barely see the knock count of 1 at around 30 seconds into the capture. This occured around 2150 RPM. Also, noisy valve lifters can trigger the knock sensor, thus inadvertedly cutting power.

One of the handiest features of the tests is that you can save the data in TMOs proprietary file format to be read by the TMO Datalogger, or export the data to a .csv file and work on it in Excel. This is an example of an Oxygen Feedback Trim and Oxygen sensor test I ran.

Finally, you can graph the data in Excel in various ways. Here's the Oxy Trim in relation to time. The oscillations hover around 100%, meaning it's reading a stoich value for the trim data. The oxy trim is used by the ECU to build the actual long-term fuel trim tables that the ECU uses when in a closed loop environment

So now I have a bunch of tests to run and document. This should be a great way of monitoring the health of my car!

I made an OBD1 to serial datalogging cable with some instructions off of dsmtuners.com. This cablet hooks into the serial port on the back of my car PC's docking station and connects to the diag port of my car's ECU. The only difference I made to the cable was switch pins 2 and 3 as the design on the website is geared for a Palm Pilot

Just need one 10K resistor and one 1N914 diode, plus the serial female RS232 connector

I actually had to hacksaw the back of the connector to find something to solder on to...I honestly thought this was too scetchy to work.

I ended up replacing the alligator clips with female connectors...just wanted the clips to test to make sure it worked.

The transmit wire comes off of serial pin 3 and connects to pin 1 on the ECU diag port. Pin 5 on the serial splits at the end and shorts pins 10 and 12 on the ECU diag, allowing for serial communication on pin 1.[/img]

hahaha, that's awesome. "Hey Randy...what are some links you have?!"

Yeah, that is some crazy shit! I couldn't believe the clips where they show the speedo creeping, racing rather, from like 60 to 160 in a couple seconds!

I just did some googling on the MMCD cables...looks like I'll be hitting up the local Radio Shack for some supplies - thanks! Let me know your e-mail and I'll send you the TMO software.

Damn right, can't wait! I'll probably be taking up residence at the Holiday Inn once more. Let me know if anyone wants to stay there.

Dude, that's too much! Off to the bookstore for some Diet Coke and Mentos!
