Yup - similar to the older roms, but one annoying and significant difference - the older roms had a set of bits after the ECU id that told you which SSM pull routines (and hence parameters) are used in the rom (e.g. 10111111 - P1 is used, P2 is not, etc.) This made the SSM routines the starting point, since it always followed the same order. Not so with this rom

All the SH7055 and SH7058 roms had a so-called engineering parameters routine that converted certain key parameters into 2 byte or 1 byte parameters (this allowed for more parameters to be logged in days gone by, when bandwidth was more constrained with respect to logging, i.e. before fast poll or the mode 23 patch)
