As I understand it, the dealer will "flash" your RC390 ECU with an "Akra" flash, which I assume gives more fueling, assuming an akra exhaust. This flash essentially rewrites the ECU itself.
If, like me, you have a PCV, which makes adjustments to the ECU, is there any legitimate reason to first flash the ECU and then make dyno adjustments via the PCV to dial it in, or is flashing in this case an unnecessary step given you can also simple dyno tune the un-flashed map to the same specs without first flashing it?
Unless I'm missing something, it seems
1) Flash > PCV and no Dyno
2) PCV + dyno > flash and no dyno
3) PCV + dyno = Flash + PCV + Dyno
Ergo, if you're gonna PCV and dyno to create custom map, also flashing the ECU as a first step is superfluous.
Yup? Nope?
