Remapping ECU 2010 GSA

[Balders1450]

The downsides to the remapping, as I see them, are that it might at some stage be possible for the dealership or indeed BMW UK to detect this and void any possible future warranty claims. Also, some ECU's have a flash counter which only enables them to be reflashed so many times. I don't know if this is the case with the BMW one. Any future revisions to the OE fuel map would obviously overwrite your custom one. It was certainly the case that there were a number of fuel map revisions to the earlier bikes, although I haven't encountered any on my '09 GS.

As I said, I'd be inclined to fit a Power Commander V with the Autotune wideband lambda sensors which after initial setup on the dyno should enable the bike to constantly remap its fuel requirements on-the-fly. You'd also be able to remove it for servicing or warranty work and sell it to recoup some of the costs when you sell the bike. The initial outlay is, however, likely to be more than the cost of a remap.

I think the important thing is that people who fit full systems, at the very least, have the bike run on the dyno and are prepared to do something to change the fuelling if, as is highly likely, that's necessary. That's why my bike is currently fitted with my Remus can and the headers are languishing in the shed until I fit my Power Commander and book some dyno time.

Let us know what you decide to do and how it works out - I'm interested to know the results.

A number of "Tossers" are having their bikes "tweaked" on Saturday, see "harry the cat's" original post Hilltop Motorcycles, Earl Shilton That's where I got the idea from

up to and including the 09 bikes ave a flash limit of 14 with a counter. This is according to the makers of the GS-911. No idea if they have changed anything on the 10 on bikes but I wouldn't have thought so.

Thanks for the information. That would suggest that BMW dealers can tell, via the GT1, how often the EPROM has been flashed.

And the date when it was done

Re map

I put de cated Bos headers and zard exhaust baffles in on r1200s and took to hill top for dyno and remap. On dyno bike running very very weak and making 85bhp and 77 tork at 6700rpm.after remap bike mixture spot on 112 bhp at rear wheel and tork increased plus max tork now at 3800rpm mate had his s done got 124bhp at rear wheel so had 08 gs decated Remus rear box he got 109 at back wheel and better tork lower down rev range on all bikes fuel cons improved as did throttle response
