Tech Article: How to Setup and Datalog with CROME PRO

First, make sure you have the PRO or DEALER version of Crome…you have to purchase this from the TuneWithCrome.com website or from my website. Receive your Registration String and enable the datalogging features in your version. Once this step is complete your “About Crome” screen will look like mine.

Next, install the USB Device Drivers for the datalogging cable you are using. Hondalog, Hulog and my Data Cable all use the same FTDI Drivers, you can find them at the FTDI website here:

User the NEWER, Auto Installing Drivers FIRST, before you plug in your USB cable, find that auto installing driver here:

Use the OLDER, Auto Installing Drivers if you have problems with the above:

http://www.moates.net/zips/CDM_Setup.exe

Install the drivers and make sure they INSTALL CORRECTLY before going any further.

Plug in your USB Cable, and watch as Windows automatically installs the Drivers.

Verify they are correctly installed by going into your device manager and seeing the driver setup as a COM PORT

Note this COM PORT #, Write it Down for LATER.

Next, go into that COM Port within your Device Manager and check all settings, go into the ADVANCED Properties.

Make sure the Latency Timer is set to “1” as it normally defaults to 16. This should be the only change you have to make. Click ok and close out of all of those open windows.

This will then show you what COM PORT # your Burner has been Assigned. You can see on my computer it is COM5

Right Click on the COM, and choose PROPERTIES. Click on the PORT SETTINGS Tab and choose ADVANCED which opens this screen.

Make sure the LATENCY TIMER is set to “1” instead of 16 which is the default value.

Now, ok or close all of those windows and unplug the device and then plug it back in. This resets everything and as long as you plug it back into the same USB spot, it will always assign the same COM Port #

Now go back into Crome. Upload your ready to go file to the Ostrich, make sure datalogging is added. If you are using a chip, make sure to burn the chip with datalogging added. Also make sure checksum is removed, and “J12” is removed in the ECU if you are using a USDM ECU, and if you are using a JDM ECU make sure J4 is removed.

Next go into your Crome Settings, make sure you enter in the proper COM PORT # that you wrote down earlier.

DO NOT CLICK “DETECT CONNECTION”…IT DOESN’T WORK, at least not at the time of me writing this article.

Click OK and exit out.

Now, turn the key to your car to the ON position, make sure all cables are plugged in correctly and start datalogging.

Troubleshooting Tips:

- Make sure J12/J4 removed from the ECU

- Make sure your USB Cable is plugged in the CORRECT direction on CN2 port. Ground is ALWAYS pin #1

- Make sure checksum is removed

- Make sure Datalogging is added to the chip you are running in your ECU and make sure the chip was made with CROME, the most current version

- Make sure you are not getting a SOLID CEL from the ECU or Chip, this will never datalog if this is happening

- If all fails, UnInstall All programs and drivers and re-install EVERYTHING, and try again.

If you are STILL having connection issues, this is how you test if your cable is working. DO THIS AT YOUR OWN RISK, I am not responsible if you fry your cable performing this test!

Download REALTERM or another Serial Terminal software, here is the current link:

http://realterm.sourceforge.net/

Install the program, plug in the USB cable to your laptop (with no other software running) and start the newly installed software.

Click on the PORT table in the software and set it up to look like the following, making sure you are setting the COM PORT to the same one that appears in the DEVICE MANAGER for your logging cable, mine comes up COM 5

Make sure BAUD is set to 38400, Port is set to the proper COM #, Receive and Transmit both have check marks, Parity is NONE, and Data Bits is 8.

Next click on the OPEN button and the Port status in the bottom right hand corner should change.

Now, take your datalogging cable and connect a wire in between the TX and RX pins on the cable. On my cable, the Hondalog and Hulog, these should be pins 2 and 4, see the following picture.

Now, click in the MAIN black screen of realterm and hit any key on the keyboard. If the cable is working correctly, you should see RXD(2) and TXD (3) light up in YELLOW on the right hand side of the program.
