RomEditor V3.5.4 & HondaLogger V3.5.4 are available in the user download area.
There are some minor changes and fixes, but the main change is to fix a problem where datalogging a ROM would show the ignition timing increasing with RPM. The actual ignition timing used by ECU was correct; only the datalogging in HondaLogger and RomEditor was incorrect. ROMs will need to be updated (to version 36) to correct this problem.
RomEditor V3.5.3 had one bug fix, where table tracing was not working correctly for 3 bar MAP sensors (stopping at the 10th column). This was only a datalogging issue - the ECU was adding fuel and retarding ignition under boost correctly.
