Well yes and no. They do have a low tolerance for low voltage starting but that goes for any electronic engine Once started the charging system keeps up with the demands. We have sold a few of the Honda DTS engines with no issues. I believe Honda’s system has been available for 6 years or more.I heard these need healthy and charged batteries or they refuse to operate, leaving you SOL. Is this true?
What is a bit ironic is in a lot of cases (the outboard crew can correct me if I am wrong) the throttle has been technically fly by wired for a while. The only thing the cable controls is a TPS sensor which via an ECU tells an actuator how much to open the “butterfly” and tells the fuel system how much fuel to give. That’s the short version, there are also inputs from other sensors that come into play as well for proper fuel mapping. Anyway to get to my point. In the case of the throttle all they have done is removed the cable and put the TPS in the control lever. That’s the simple way of explaining it.
