I want to write up a small review about RS2E ECU REMAP for Gen4.
At this stage RS2E offers 2 Power Maps for Gen4
https://rs2e.de/en/services-prices/catalog-bmw-motorrad/
BM.S1.B.5.20R - for Race exhaust
BM.S1.B.5.20S - for stock exhaust
And they offer to shorten throttle grip from 68 to 58 degrees (and calibrate it so you dont need to buy GS911).
They are still working on Racing Maps which, as I understand, will include same features as their's Gen3 map: Wheelie control, TC.
I went for BM.S1.B.5.20R and shortened throttle grip 2 weeks ago with a plan to test all that at Jerez last weekend.
Robert & Rainer were very kind and helpful to arrange a very quick turn-around as my timing was very tight. They got ECU/grip on Thursday, applied flash on Friday and I got all back on Tuesday.
At Jerez, the install of ECU and throttle was plug and play.
Initialization sequence is the same as with Gen3: turn on ignition (all kind of errors will pop-up), turn off ignition and wait 2-3 minutes. After that all errors are gone and the bike starts fine.
I haven't ridden Gen4 on stock ECU, so can't really say how it compares performance wise. Comparing vs. Gen3 - I do feel much better acceleration (or torque I would say) past 8k rpm.
Shortened throttle is a joy, altho took some time to get used to a smaller diameter (I used TGP with a fatter grip on Gen3).
Overall I'm happy and can't wait for their Race Mappings.
