I am looking for rotary fuel injection timing data for a sequential end-time setup. Any suggestions? Does anyone know how the factory 20B ECU operates?

i asked about it a few months/years ago and the response that i got is that all the manuals are written in Japanese and above that, not too specific either. if i recall, i believe he (DMRH) told me that the reason was Mazda didn't want people bringing the Cosmo to anyone but them for work.

 

okay, i wasn't sure if my memory was failing so here is the post i made after i spoke to DMRH. it's in the FAQ sticky of this section.
