Are Modern ECUs Too Complicated?

Why can't you tune any ECU however you'd like or fit any aftermarket ECU to your vehicle without a care in the world?

Ryan Nicholls Powertune Australia answers these common questions and more in relation to what can be done with the right skill set and tools, in this case, MoTeC's M1 Build and knowledge of C# (C Sharp) development language.

Some key takeaways from this chat include some insight into CAN Bus, LIN Bus and FlexRay, plus the fact that reflash tuning is not equal for all platforms, and some are much better developed than others. Ryan also mentions how you are often relying on an interpretation rather than an absolute when it comes to reflash tuning software vs the lack of OEM information, as well as sharing encouragement from Ryan for anyone interested in learning the skills he has to do so, even at a hobbyist level.

This interview was recorded at GTR Fest Australia, where we somehow managed to film more about EVOs and MoTeC ECUs than GTRs, and had a ball doing it too.
