Noob Questions... (please be gentle)

But the "hidden" benefit for using a successful serial ECU installation is the BIG differences at partial throttle openings - WOT charts/graphs/claims are the art of pointless.

If you are after challenges...well...you know what to do.

best, peter

I'm still a bit confused... What exactly is an "aftermarket serial ECU" and why would someone want to use it?

Careful.....you're going to fall into the rabbit hole and then you never know what you find; go ask Alice.......

No offense to Peter, but on an R11S, a serial ECU is about as useful as a gold plated brake reservoir.

Before we open this Pandora's Box, look for a thread I started called FRK and the Sprocket...or something like that. It started off pretty normal and then grew. Even has a few useful things in it if you are prepared to dig.

FRK and the Sprockets

Shreddr started one too. Get a cup of whatever and read up.

He has an R12S.

Well, you guys might not rememebr me, but I also played a role in that rabbit hole. I think I actually got in a bit of a tif with our estemed moderator.

It was a brutal Pelican coming out party for me. I came down on the side of not being impressed with whomever was marketing the FRK at the time. It's knid of ironic that I now have an FRK mounted on my bike after all of that.

Rather than open up that can of worms... I guess I'll keep using the FRK at the moment, checking my sparkplugs regularly and decide later when I have recovered from the purchase of this bike if I want to spend the $$$ on a PC and dyno tune or call it all "good enough".

whew!

PS: I still have no idea what a "serial ECU" is... :P

"serial" is an euphemism of mine : means an ECU (or something that claims to be an "ECU" of some sort the likes of RB and/or PC) that plugs in "after" the OEM ECU and modifies the OEM ignition/injection signals according some stored maps (max 2). All these things are supposedly working in open loop. In RapidBike's case there's a great mystery (at last to me) about why works with steady L=1 values (thus requires OEM L-sensor replacement with other gizmos).

In fact only MoTec is an ECU (but...requires the hit the bank plan). That said a friend - Yam R1 retired racer - has an used M400 unit and he's willing to give it to me for free - in exchange I'll give him some concept design for his future home (my BIG troubles may start right now, maybe not he he).

But indeed this whole topic is a gigantic rabbit hole...maybe the best thing to do is to stay away from all that (maybe pointless) mess.
