I have been thinking about the ECU's and what Stephen RC45 said about depending on what unit you use, I have 2, both PGM2, but with different manufactures and numbers. Ones an OKI electrical industries model and the others a Shingenden. I assume they are both the same spec, is there a resource here where I can find out this info, as in the parts manuals or workshop manuals with out hassling members for info.
