I am trying to figure out which pin on the ECU is responsible for selecting between the two different map sets. Based on the schematic from this '08 HRC manual (http://www.firebladezone.com/docs/08CBR1000-HRC.pdf) it seems like the mode selector is pin24 on the gray connector. This pin is not connector to anything on the non-HRC schematic. Can anyone with access to a newer HRC manual see if you can confirm the mode switch pin, or better yet, post up a schematic? Thanks.

For 2017 SP2 HRC ECU pin 29 grey connector is FI\IGN Mode switch which is mapped to left of Hazard Switch when using stock left bar switch cluster or Map Selector on HRC left bar switch cluster.

Pin 29 on the street SP2 ECU grey connector is open.

Thanks. Pin 29 is in use by something else on the 08-12 havent looked at newer models. On that 08 HRC schematic the ECU pin is called "MOD SW" but is also connect to the hazard switch. I wont be able to test this until my order from cycleterminal arrives.

In this discovery process I should imagine the actual pin across model years is not important, just that the same pin being used for an HRC specific function is not being used for anything on the stock ECU is probably more important.

I think the pin is going to be consistent on all the standard Keihin (non-HRC) ecus. All that you need to do is connect the pin to ground and the second set of maps kick in after the next gear change.

EDIT: Pin 24 on the 2006 HRC schematic goes to an empty connector.

Pin 24 for 2017+ is a common ground on both stock and HRC grey plug.

I think it fair to say that nothing on the 2017 is going to be similar.
I don't think that is the key take-away here - I would not be so concerned with finding literal matching pin outs across years.

That thought process may limit your discovery. I might focus on common use and vacant pin outs across stock vs HRC ECU for the same years to narrow down on functionality discovery.

But that's just me.

Maybe its just late and I need to go to bed, but that is what I am doing. The 08-14 schematic only has a few empty pins on the gray ecu connector (which is sensors/inputs) and pin 24 is one of the empty ones. So far the 07 and 08 HRC kits use pin 24 for the mode switch so it seems like that is the best bet to start testing for me to get mode switching working on my stock 2012 ECU.

My ECU connector came and it has way more pins than I will need for my bench harness. I should be able to use one of these pins to add the map switch to my factory harness.

Hello. I also want to switch my ECU to MS0 to MS1.My bike is cbr1000rr 2006 sc57. In the white plug of the ECU, pin 24 is empty.

If you have the ability to tune the MS1 maps try grounding pin 24 and go for a ride. I think the maps switch after the next gear change.

I will test, I hope there is no way to kill the ECU. I was wondering if you know a factor and an offset for the IGN tables,
I think the factor is 0.351563 and offset -20, but I'm not sure. I am working with winols and I found TPS Map, IAP Map, IGN Map, injector balance map and REV limiter but I do not find Launch control map and top speed limiter.

So on the 06/07, the French 1000rr's are restricted to ~106hp and they do this running the second mapset as default with a highly detuned map. In FSM for the French model there is a ground wire going to pin1 on the gray ecu connector. This pin is empty on the EU/US models. Pretty sure this is the map selection switch for the non-HRC ecus. Unfortunately only the 04-11 appear to have the dual map sets, the 12-16 only have 1 set.

I have a Cali bike and B connector pin one was grounded. The wiring diagram showed this is only on CA bikes but all ecu's support it. wired a switch in and the bike now revs faster and runs lean with it cut, ground it and it runs like stock. I have yet to do a rode test but it definitely appears to be a map switch.
