In you digging through the maps did you figure out if there are two different ignition timing maps for primary and secondary spark (for twin spark engines). I am running my primary spark plug from the secondary coil (stick coil delete) and I am not seeing any major power difference due to the timing (but others say otherwise).
Maybe if you compared single vs double spark data (2.2 vs 2.4) you could figure it out without too much effort.
Thank you

No there is not double maps for ignitions. Be sure for that. You can change all ignition coils from R1150 twin and fit one 4 plug ignition from fiat punto GR or peugeot 106 Ralye.
Here is a ignition coil from Fiat punto GT. This coil have 3 pinouts. two for ignition signal, one for 12V. So if fit the one signal of primary ignition coil, and one from secondary, you can take out two pairs of ignition wires for 4 spark.
Here are thw ignition coil from R1150 twin, there are many problems to these ignition coils, because the registor is in to spark pipe. Very hot, problems with water poorr electrical performance spark.
Look what happen after many miles .. :
A best tip is replace all ingnitions from R1150, fit the ignition from puntoGT and fit 4 wires going to sparks.
The improve by this modifications gives more volts than poor BMW ignition coil. (from 14.000 Vlots to 15.000 Volts).
That gives much better consumptions, no problems, water proof (is under tank), better ignition, for the entire life of the bike.
So when or if will have problems with primary ignition coils, one solution (low cost) is this :
Take a look at this thead, a guy fit a ignition coil with wires to his R1150 twins, like the standard one of r150 single.. :

Anyway, you ask for maps.. There are 3 types of standard stock chips for R1150GS. One for R1150GS single spark (1999-2003), one for R1150GS twin spark (2003-2004) and one for R1150 advendure. These files are very seams, same power, same poor (very lean) AFR, same problems (low torque at low rpms) poor performance at high and more else problems. The different is only to the bin file of advendure. This file has double sets of ignition timing advance maps, one set for CCP 30 87 (normal petrols 95+ octane) and a seconds set of maps (low quality, low octane or enrons petrols, by CCP 30 87 86. Also this funtions by CCP at 30 86 87a 87 works at all R1100- (The R1100 to switzerland has CCO at 30-87-86-87a low performance) , but for R1150 works only at R1150GS ADV. To other R1150 (non ADV) a tip is to connect the 30 87 87a, this setup gives more fuel, a little richer AFR. A tip for R1100 fo use low octane petrols, is to connect (like swiss model) for R1100GS,R CCP 30 86 87 87a and for R1100RT the 30 86 87 (not 87a).
For R1100 the pins of CCP is : The 87a for narrow tubes, the 87 is for lambda, 30 is ground, 86 is for low ioctane.
FOR R1150 the pins of CCP is : The 87 for lambda, 30 is ground, 87a for a little richer afr and 86 (works only for ADV) is for low octane petrols..
There two type of ECU for R models. The Bosch motronic MA 2.2 R1100 GS,RT,R) and the bosch motronic MA 2.4 for all R1150 (RT,GS,R,RS,RT) and for R1100S, R850C and 1200C..
All motronic 2.4 are same to all R1150, to R1100S and to R850C and R1200C.
BMW just fits twin spark at 2003 to boxers engine and make a poor bin file for ECU., just for compliance with the
European emission standards.
My opinion for these different bin files at stock chips for R1150GS is this one.
It is preferable to use mix of maps from r1150rt-rs in conjunction with a map of the r1150gs single, to have maximum torque at low and medium revs of rpm and maximum power at high revs.
This is exactly what I try to do to my chip.
Bmw just made different file types for reasons marketing, due to modulation of the motorcycle. There are many types of bikes, with the same boxer engine.. (RT,GS,R,RS,S).
