I'm bigboring a 97' 916 Bipo to 955 with SP heads and G cams.
So I'll need a more accurate injection.
The best solution is P8 with SPS TB (dual injectors per cylinder / sequentially command).
Problem : difficult to find and many parts to change (loom,flywheel, alternator cover...) and sometimes expensive...

Some 996 had dual injectors per cylinder TB with standard ECU. Even if this injection is less accurate than a P8 SPS one, it may be a solution.

You'd need the 1.6M B1 ecu, but it can't fire the injectors on the same cylinder sequentially likw the P8. I think it was SP or SPS that had this set up.
I'd be more concerned about the exhaust side.

[jejemg]

OK, I was awared about non sequentially fire.
Of course P8 would be the best solution but...

Then,the bike is fitted with 1.6M but cannot talk about version (B1???).

[Wozzap]

The standard 1.6M cannot fire two injectors at all. For 955 even with G cams, twin injectors aren't necessary unless you are after race bike revs. Just get a good exhaust!

[jejemg]

I've seen 1.6m A0 /B1,...
There are different version of this ECU?

[Shazaam!]

Weber-Marelli IAW 1.6M ECU
One injector/cylinder: 748, 916 Biposto, 916 Senna, ST2

Weber-Marelli IAW 1.6M B1 ECU
Two injectors/cylinder: 996 Biposto, 996S

Note: The IAW 1.6M uses a crank timing sensor at the cam jackshaft whereas the 1.6M B1 ECU takes it's timing firing points from the crankshaft.
