I was really tempted as well, but I've done some research on Coober and the company is so dodgy I'm feeling very, very reluctant.
@barbagris advocates a lot for them on this forum and states that they work (among others) for ktm doing engine analysis but the only info I could find that connects them with KTM is that they sued KTM at some point not too long ago because they stopped selling them empty ECUs to program, or they found out and shut them down. I bet that's the reason they switched to LM devices.
Add to that that anything they say on forums/facebook is either incomplete or confusing or straight up does not make sense in English. If you say that maybe it's a language barrier, but honestly for a start these guys have an entire branch in US, and second anything they say is so far away from sound engineering and logic that it absolutely baffles me that they can put together any kind of device that can do anything.
I have had an email exchange with them and after they answered with nonsense, I tried reformulating the questions more specifically and they just did not answer.
For the record they are saying that some 890s are showing the check engine light with the LM because the "signal structure is very bad", I interpret this as "the lambda sensors are broken and the LM can't work with them". Now imagine if that was the case surey these bikes would have some problems even without the LM?
On their FB they posted a year go that they have up to -10hp on 890Rs after a certain delivery date, with a number of them having low oil at delivery. Not sure if these bikes are brought to them by customers in Austria right after purchase or they collaborate with a dealer. They do not offer any explaination as to why this could be the case (where's the engine analysis?).
I was especially interested in knowing since I saw Cycle World measuring only 2nm more torque at the wheel on 2 different 890Rs compared to a stock 790(!!).
Also, I noticed that they do not offer returns for LM devices in europe. I said I'm willing to buy it and try if you have a return policy if I'm not happy with it. They said no. This is obviously in contrast with EU law (that states that they must allow for returns within 14 days), but also their excuse is that the device is "customised" and "sealed" and locks itself up after calibrating on the bike and cannot be resold etc. Needless to say, a load of absolute crap. Note that the owner himself (Brani Stojakovic) is answering the emails (with this bullshit).
Oh well, I even tried researching the parent company owned by the same guy, Innalpin gmbh but there's nothing on the internet. If these guys were doing research and engineering for manufacturers surely they'd advertise it on A website?
My conclusion is that their piggyback devices after the KTM lawsuit are very much in danger of being pulled due to KTM/other manufacturers suing and that's why they keep a low profile. I'd also argue that this is their main business. Their engine analysis seems limited to pulling data from dyno runs. The only data about their devices is coming from Pirate Racing and it's not clear their affiliation, I'd argue it doesn't count as an independent test. Yes, some people had problems (eg. throttle stops working).
Maybe
@barbagris can chime in if he knows more
