I just grabbed myself a left over 22 1000rr.

What's the general recommendation on flash + exhaust for a track rider? It seems that rs2e is pretty well respected based on what I read here. Should I go for an akra S-B10R5-APLT (probably run me about $2k), and send off my ecu for their race map pro BM.S1.B.4P.23R flash (about $800)?

Maybe asked another way, any opinions of better options than the above?

Well, I certainly can provide a proving flash that has won many races and set a few track records. KWS and Top Pro Motorsports will both provide excellent feedback.

The AKRA has shown the best results on my dyno on a 22 in compare to the Arrow and Akra EVO

\do you have dyno graphs for arrow and akra? and dyno of the chinese akra vs the real akra? BT moto just posted a dyno of an arrow vs akra on their youtube channel this morning and showed 9-10hp difference up top which is huge... just wondering how real/credible that really is.... i also saw you post before, the chinese knockoff headers on ebay cheap show same results to an actual branded akra? to within 1hp? i have a arrow low mount brand new not installed and kinda regret it as i do want as much top end power as possible

i am wondering if the Y-pipe outlet on the arrow is just too small choking high rpm power or if it is just overall design

if you are interested in my arrow low titanium system i can sell to you, depends how much power your looking for, i myself am looking to extract as much top end as possible for drag racing and 1/2 mile events

2022 results on the Arrow vs the Akra . 2 bikes, same purchased dates, It was not 9-10 HP difference on the top end of the RPM scale. It was about 4HP however, and the torque was 2 ft pounds less on the Arrow. Could just as easy be the build of the engines. Thats just the way it works on factory assembly hardware. You have to test on the same bike, same day best case, same temperature and humidly.

That is one reason I dont say with 100% of the results as it was 2 different 2022 S1000RR bikes.

If you look at the data I have on my 2021 bike I have dyno'ed on different hardware only, you will see that this bike shows results of between hardware only. I try my best to do days with the same temp and humidity.

This is one of those test days

K67 Akrapovic optional header / long can akra muffler /...

can I keep the original headers, and swap them back when I’m trying to make a claim then lol Thats what I would do!

ya i saw that thread you are posting which is why i am curious to the chinese knock off akra, i am debating on having a local shop make the Y-pipe outlet larger and the muffler inlet larger on my arrow exhaust or if i should source a new exhaust. after purchasing a whole arrow exhaust already i am not rich anymore so i am interested in the chinese knock off if it is worthwhile

 

[BMW_388]

The Chinese knock off is the same in all areas of design overall. Fit and function.. excellent.. The only issue I see that the Chinese Akra has is the outlet neck area of the tube shape is slightly different. This is all hydroformed at AKRA so they can do alot more, where the Chinese are making bend sections and then welding them all together. The chinese is a great header set. I have the SS and Titanium on 2 of my K67.

I see that chinese version has four sensor bungs. But the full (real) akras I'm looking at seem to only have two. I guess the two extra are for self tune or something like that? What do I actually need here?

 

[BMW_388]

All the K67 headers have 4 O2 sensors ports. Required also.

The rear O2's are after CAT and still have to be there on the Full Exhaust headers, but provide no feedback in AFR targets.

 

[testiesalmon]

I've just spent the past couple of hours looking at options here and its doing my head in.

I think I'll just get a second ECU from somewhere and send it off to rs2e. That'll set me back a bit by the looks of it, but at least I'm good for if something far left field happens and I need to take the bike back for a warranty call.

My understanding is you can't simply swap in another DME and expect it to work without issues. The TFT display, ignition key cylinder, and DME are all matched together.

far out

 

[testiesalmon]

I'll just get woolich's system then I guess, and flash to the stock bin if I need.

Isn’t there also something about mileage mismatch between the DME and TFT causing issues?

I recall that being an issue too and why I just used the generic having issues catch all. BMW_388 would know better. When you send your DME to get his flash, he also requests the TFT panel too from what I remember.

ok, I'll throw the bike in the bin then.

Seriously, I've come from Aprilia, and this is way easier when going with their approved akra pipes and ecu unlock codes. And Jap bikes before that, where you can access their factory race tools at a fairly reasonable cost.

No TFT cluster needed unless you want the pretty M logo and M1000 splash screen. Then I can put in target PSI on My Vehicle instead of the worthless 42 and 36 numbers. Then target warning can actually work if you wanted.

I can do mile matching, marry, keys, for all BMW 2006-2023

As far as I know woolich still cant tune an 2022 and on BMW S1000rr.
You are making this more difficult then it needs to be, IMO. 2 best options are take your ECU out and send it to BMW_388 or buy the Flash from Brentune and flash it yourself. No need to remove ECU and can flash back to stock whenever you need to with Brentune.

I realize people think removing the ECU is such an issue. Guys, I do this for the people that want 100% non invasive programming to the ECU, and, FULL writing of tables that the handheld cannot put in the ECU. The handheld leaves residual traces in the map code when you put it back to stock maps. It has to. It loads its own bootloader and checksum. My method of BDM to ECU and writing the MPU directly puts the code EXACTLY back to the stock code as when you send it. That is the maps checksum completely intact, and BMW bootloader completely intact.

So you dont blow up an engine, its never an issue for sure. You put the ECU back to stock maps with the handheld, then go to the dealer for whatever service made you want to go there, and its done. The ISTA loads, the ISTA updates whatever you are there for. Now the issue is if you blown an engine up. Then BMW Motorrad will request a read on the ECU that will find any residual code and checksums that are out of place. Then the conversations start with BMW Motorrad to dealer. Whats on the bike? Take pictures of all 4 sides of the bike. The investigation starts for decision on warranty work.

Woolich cant do from June 2021 to 2023 still. The RSA code is still not leaked out of Bosch so they can get to the bootloader.

Here is the basis of the law in California that will some day spread to the whole North American EPA regualtions.

California's ECU Tuning Policy: Your Questions Answered

Well, all the answers we could pry from CARB and CBAR, that is...

This is a webpage on the CheckSum explanations.

https://www.reddit.com/r/cars/comments/wl0ncn
The fueling and spark tables are set in stone by BMW Motorrad. This creates a checksum that is the same on every ECU in that OSID sequence. That is why OSID is so important. I can get around OSID specific numbers and force program with a bootloader with the BDM. No else can do this. The handheld loads a bootloader, it loads the few maps it can load. It then creates a new checksum in 4 places. Some day in the near future ISTA will look at these checksums and then, it will fail to load. That will result in the dealer telling the customer that the ECU has been tamper with and your warranty is voided. The only way the dealer will be able to access the bike is with a replacement ECU. Its coming.
