As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.
When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.
Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.
Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.
Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.
Thanks for your patience and support!
Thumpa, it sounds like they did not do an adaption reset, go back and advise them of what has occured re the uneven idle and stalling
EngineerK9, relocating the AIT is bad news and will cause problems, as for the DynaBoost, very doubful it does anything
The AIT is supposed to monitor the temperature of the air actually entering the engine not the air temperature elsewhere around the machine which may be hotter or colder than the air in the air box as it enters the engine
With the AIT mounted external to the air box it is not possible to do an adaption reset and build a valid adaption table because the air temperature values do not reflect the temperatures inside the air box as it idles building an adaption table
There are other factors as well such as circuit loading with what you have done which are another story entirely
As for the DynoBoost, take a look at the claims
"Gain 15% additional horsepower, 15% torque combined with explosive acceleration."
Then when you read the specs it claims that it is increasing fuel to the engine and at the same time claiming a 6% improvement in fuel economy
Believing that is around the same as believing in pixies at the bottom of the garden, a glance at the specs and claims on other products they sell is enough to know to take any claims with a very large grain of salt
There is simply insufficIent information provided by DynoBoost to make rational decisions and the product provides no ability to look at or monitor the actual air temperature or O2 signal values
All of these snake oil products are based on the false assumption that all problems in the OEM ECU's are due to a leaner than optimum mixture where the problems may be either richer or leaner in different situations or even simply poor combustion due to ignition circuit problems. It is not a one size fits all situation and different firmware versions in an OEM ECU may well behave quite differently
A good example is the random stall, that is a problem of the ECU turning off the injector during over run too aggressively and it is a routine external to any mapping table so richening the mixture across the board is not going to do anything of any real benefit to resolve the problem
Other test results show what was presumably the earlier versions firmware on the rich side causing problems
Coupling the AIT with the DynaBoost together means any real time values for either AIT or O2 from diagnostics are meaningless
Or it may just build up fuel in the pipe to damage the cat, ignite and coke up the 02 and scare little old ladies as you stop at traffic lights
One of the challenges with the AIT in the airbox directly over the motor, was that in Sydney traffic the airbox temp was in excess of 53degC, thereby leaning the fuel mixture, making the bike virtually un-rideable & certainly unsafe, by positioning the AIT to the front of the bike, ensures that that situation cannot occur, all other times the airflow over the new AIT location & in the airbox are virtually the same
From my experience, the Dyna boost has certainly improved the running of the bike - I'd never make any excessive claims, as I don't have dyno figures
I'm still achieving 25klms/litre -my bike is running better than it ever has, accelerates cleanly from 1,600 rpm & "pops" occasionally on the over-run, wheelies with little effort, no stalls etc etc - so I'm happy
I saw the same problem when I got stuck in construction traffic going through Rocky Mountain National park. The air temp was about 55f and the dash was reading 102f. It ran terrible until my dash temp lowered which took way longer than expected. I am sure my problem was caused by the pod mod. The iat sensor sits right behind the pod mod blocking it from clean airflow. I would like to keep my iat sensor in the air box but move in up in front of the pod filter.One of the challenges with the AIT in the airbox directly over the motor, was that in Sydney traffic the airbox temp was in excess of 53degC, thereby leaning the fuel mixture, making the bike virtually un-rideable & certainly unsafe, by positioning the AIT to the front of the bike, ensures that that situation cannot occur, all other times the airflow over the new AIT location & in the airbox are virtually the same

I just got off the phone with the U.S. DOT National Traffic Safety Administration (1-888-327-4236) they issued me tracking # 10825606. I tried to file another complaint but no so I asked for a supervisor. He came back and said that he was instructed to forward my complaints to the technical staff for review. I also told him about the recalls in Canada and Australia. So if there tech staff calls me can someone on this forum confirm that with an updated ECU from numbers 8543015 or 8543016 changed to 8532185 the random stall is eliminated. This will change the air fuel mixture to richer and will stop the random stall? Who should do this KTM? BMW? or Husqvarna? I also tried to contact Tyson Tyler at KTM NA

Relocation of the Ait sensor worked ok for me.Thumpa, it sounds like they did not do an adaption reset, go back and advise them of what has occured re the uneven idle and stalling

Thanks to Paul C, Wayne C, and Mark H for your insight. So what your saying is if I can find a US East coast dealer with an OSS tool computer able to install or upgrade my ECU firmware to # 8543016 I'm good to go? Any dealers out there close to Maine able to do this? Or do I need to remove the ECU and ship it to Husqvarna NA in California? Or KTM in Ohio? Or can a BMW shop do the firmware rewrite?

I asked for help from my dealer Gateway BMW in St. Louis last Wednesday. He was a Husqvarna dealer prior to the breakup. He said he has no influence regarding getting authorization for the upgraded software.
He stated that it isn't a question of doing it and that he could load the software but it was question of the legality of doing it. He added without the official authorization he isn't covered in case of any liability arising from the new software bricking the ECU or the newly flashed ECU failing and causing severe injuries or death...wtf? Isn't this what we are trying to avoid in the first place?
This seems odd since he was a Husky dealer and remains a BMW dealer. What a freakin runaround. I can honestly say that I am happy with my bike after the installation of the LC2 but that isn't the point.
