would this help with setting up dave?

This write-up should serve as a fairly definitive way to get your data logging cable and software to work for you.

Let’s begin with the needed components:
Laptop: My setup is a Compaq Presario 705US/ 256ram/500ish Mhz/20gig HD/2 USB ports
Cable: Xenocron’s USB data logging cable. (You can use a Moates cable like HondaLog or Hulog as well.)
www.xenocron.com/products.php?page=rs232 , or www.xenocron.com/products.php?page=moates

Drivers for the cable: www.ftdichip.com/Drivers/VCP.htm The second one on the list is the one for Win98/2000/xp, the one for my setup. All the drivers can be found at the bottom of this page:
www.xenocron.com/products.php?page=rs232

ECU: P28 chipped and setup for data logging with 4 pin header inside the ECU. J12 is cut for Crome
Code Chip is burned with: P72 base with Crome Pro with datalogging+RTP enabled and CheckSum removed
Datalogging Software: Freelog v. 1.0.78, Remember to unzip or decompress everything in these folders. I separate my files so that I don’t corrupt one and can try another version. Just put your newest version into a new folder right below your old version that way if one freaks out you have a back up.

So you have downloaded all the stuff above and bought one of the suggested items or a known working item. Make sure you know where every software item is, you will need it right now. So put it on your desktop so you can get to it easy or know its location.

You got that datalogging cable handy? Download those drivers yet or have a disc with them on it? If so, plug your cable in the USB port. Windows says: found new hardware. If XP finds the driver already, good. If not, like mine didn’t, then click install driver and click on the tab that lets you pick the location. I have mine on my desktop so I click browse and select desktop and then select the file it is in and click continue. It completes and says its ready. Hit finish. If you have the disc, just put the disc in and click continue and then finish. You should restart your computer at this point, but I didn’t!


Alright, lets get the application open and see what it looks like. So you opened Freelog and you found the “settings” section. You chose either Cui’s 1.8 or FreeLog and then saw the Comm box with 1 and all the usual data 38400, 8, N, 1. Right?

Ok so now click Start on windows 98,2000,XP and then select settings, control panel, system. In system there is a tab called “Hardware”. Under Hardware will be a section called device manager, click. Scroll down to Ports(Comm/LPT). ***Now plug in your cable again. Did you see a new Comm appear? Mine was 4. now adjust the settings for that Comm that just popped up. The settings should be 38400,8, None, 1. Click apply or ok and then exit that screen.

Still have Freelog open? Go back to the settings area and adjust the Comm box to what just popped up in Device manager. Click Apply. Plug your cable into your ECU in your car. Turn the ignition to On, don’t start the car, just On. Now, click Sanity check. If your cable is hooked up right, mine wasn’t, then it will say opening port, detected John Cui’s datalogger, closing port successful. If all goes well and you have your cable correct you can go out to the main Freelog screen and click Start and see the upper header change to “Connected!” and see rpm at 0, IAT =how ever cold it is, ECT cold as well. Crank the car, the values should start to change and be accurate to what your car is doing.

Just a note: If you have a Xenocron cable, the correct way to connect it to the ECU is with the black and red wires towards the car wiring harness and the white wire towards your chip. So it should be #1 black, #2 Red, #3 empty, #4 White.

Kinda exciting isn’t it? Ok, so youre still in awe… now drive the car and see what you would like more of then look below for the answers or read the forum for other possible solutions.

No data in boxes or slow to get data filled in: Click the Wideband tab then select a number less than the 15 already entered in the “minimum Hits” box. This will allow the boxes to be filled in faster but the lower the number the less accurate the information is. Use 4th gear for low rpm pulls and 3rd gear for high rpm pulls.
