Can't the power FC tell you the same stuff as the SAFC? I would have thought it would seeing as how it is a full ecu not just a piggyback.
Then you can sell the safc to pay for some of the power fc. That is what I would do.
The power FC does tell you the same stuff I think. But I like the look of the SAFC for minitoring things. The Power FC hand controller is very small and plain.
