software #100528 is the stock mode with Turbo, which we are discussing about in this post..... And yes you are right!! LPF can use normal stock mode, namely #100422, which is CERTAIN, as you said.
Thanks for your detailed referral, anyway, ching. That was helpful....
I dont own a LPF, but in rctech.net (western forum) people upgraded LPF with v.528 firmware without problem.
My understanding is that LPF is a 60A, while the PRO is a 120A. They share the same circuit, except PRO has more FET. So if PRO can upgrade, then LPF can upgrade as well.
