Data Logger / ECU link

Bruce G

Recommended Posts

Hi there,

I own a Race Tachnology DL1 datalogger, and I'm tyring to get engine speed data to the unit. As I understand it the CANBUS system in the car carries this information, and it's accessible from the plug socket in the footwell, but which pin is it? It would be nice to know what other data is available from the socket. Any info?

Does anyone make, or even sell, ready-made harneses for this, or know where I could get a suitable plug for the socket?

Support at Race Technology should be able to point you at the fitment you need. Otherwise, try and charm the information out of your local Hammer expert or, speak to Motec. Their data logger works with sensors, the CANBUS and the Bosch ECU, so they have all the interfaces and might be able to supply you with a cable that you can modify one end of to connect to your low level RPM input on the DL1. Motec supply the Data Logger for the Carrera Cup cars, so they know all about GT3s

I have a cable ready made. It's not as simple as it seems. You need to build a frequency converter in the wire. See details at


I recommend that you e-mail Christopher Brown at CB Racing

He did it for his Boxster and sold me the same that he had done (version 1 did not have the frequency converted and did not work well)

All the best

Any other Mac users out there using a DL1?

I am still waiting for Virtual PC7 to come out so I can run my DL1 on my Mac. (my whole life is Mac based, so I can't see getting a PC just for the DL1). Very frustrated to still not be able to use it, the software works fine in VPC6, but it can't read the flash cards or the unit iself :-(

Microsoft admit the issue with VPC6 and say it will be cured with VPC7,

Hello Macfly,

I'm a happy GT3 owner and a Mac computer user. I have VPC6 on my powerbook and have run the Race Technology s/w on some test data files with no problem. Compact FLASH mounts ok.

If you would like to consult about this problem I'm happy to do so via email (plima@ix.netcom.com)
