New S-AFC2 - knock sum how accurate?

[mosul210]

Purchasig some 550's and New S-AFC2 (soon), how accurate is the knock sum feature? Can I use it to tune? Intend on getting a true data logger in the future (when money allows) but for now can I go solely on the S-AFC2 to determine if I need to adjust my boost?

Thanks
Danny
ps: turbo setup is small 16G with Alamo SMIC

Since the datalogger just reads the knock signal from the ECU, I'm guessing the SAFC knock count will be just as accurate, because it also just reads the knock count from the same ECU signal. This is only an assumption, there might be something screwy with the way the SAFC interprets the knock signal.

I think on a 1g it will be accurate .. on a 2g it won't.
