Hi peoples, I just found another thread about this in aftermarket parts and bits, but I see someone is trying to combine the threads, so apologises if Im adding what is already known or has been discussed...🤔
Anyway, just as a 790 owner, I have the full AR system, with wiring harness, ATOM module and air box mod, and have done probably now over 1200 road miles with it....and I can say it has improved fuelling, as I can now ride it in sport mode almost all the time, without the original low rev snatchiness, and the mid range power has improved significantly, but I’ve have actually forgotten how good the original standard bike was in the 1st place....
I originally just wanted an end can that looked a little better than the original, but when I got my bike in early may there wasn’t anything available other than AR who were still developing the system at that point. I spoke to the guys there, and was told that for the full system (removing the cat) it needed the ATOM to stop it running hot/lean, and for optimum performance with that system they had just tested the air box mod which was the restricting factor in getting more/better air quantity into the bike.
I then got sucked in! Pardon the pun...🙄
I guess, with a new bike, as always there’s a lot of behind the scenes development, and people trying to mix and match pieces, and yes, I would say that the comber ECU is physically the same as the ATOM, and is probably the same part, although unknown, certainly to me, if the mappings are different...but just putting it out there, that at the moment the AR system I have fitted (myself by the way, it’s okay if you take your time, especially with the wiring harness-all very good quality connectors..etc...) does what it says on the tin so to speak...although I’ve not dynoed it, and don’t intend to as it’s made a fun bike even more fun....😁
Sorry for the long post.....Paul
