Hi! I have a manual Volvo S60 MY01 with a B5244T3. The firmware i pulled with OpenMoose (Thank You BTW!) was 20FMFP. The engine is stock, Stock injectors (Bosch Browns), turbo is mostly stock (DO88 silicone pipes and a aftermarket wastegate with a 10psi spring).
From what i have learned the 20FMFP software is well... old. All i want to do is to completely delete the boost limits and raise the rpm limiter. id like to run a manual boost controller. i was wondering if it would be easier to switch over to 20FWHJ. Can someone help me out???
I don't want to offend you but all you said from "aftermarket 10psi spring" and on means you don't know what are you doing.
Let me comment it just to let other people no to do the same "mistakes".
10psi spring is way to hard for stock turbo. You loose all boost control with it. Turbo will do almost full boost all the time.
Even if you have proper WG spring like 5psi at most then you can't just replace stock boost controller with MBC because ECU will try to keep tuned boost/load/flow level and you will get torque interventions/limp-home modes.
Not to mention with 10psi spring any boost controller would sit doing nothing

And what do you mean 20FMFP is "old"?
You will gain nothing switching to "newer" software. Changes are very minor between sw. updates.
And if you so much want "newer" software why do you want to mess it up "completly deleting boost limits"? Why do you want newer software just to make it piece of useless crap then... that is the most interesting part in your comment for me actually
