There are two tools available for datalogging on Honda ECUs from www.moates.net and they include the HULOG and the HondaLog.

HULOG: The HULOG comes in a plastic enclosure and ONLY requires a pin swap if it is an older unit. All the new units come with 1:1 connector pinning, so will differ from the pictures shown in that no pin swap is required or will be present on the extension cable. It can be mounted externally or internally, depending on whether you want to pass the 4-pin header cable or a USB cable out of your ECU.

HondaLog: The HondaLog can be mounted directly to the ECU with no interconnecting cable It can also be mounted at the end of a 4-pin tether cable. Either way, no pin swap is required (note color of wires and their order in the pictures). The unit is shipped with two pinning options in terms of the attachment header. It also comes with a piece of shrink-wrap tubing in case you want to ‘wrap that rascal’ when you’re done. Either way, it goes to your USB cable and PC on the other end.

Pictures are shown below for the two units. The installation header is a 4-pin latching unit, and comes with the moates.net Honda Chipping Kits. You can alternatively use a 4-pin 0.025″ square-post breakaway header. Please take note of the directionality of the latch on the interconnecting cable though, since that is critical.
