Since mine is still down waiting parts, panel exposed, now is the time I guess. Where is that hidden allen screw?

that's got to be the one I didn't find while getting the ignition switch off, had all the bolts out on the front and figured it was just wire holding it in place.
Hmm...I'm not sure if they would be related.p51super10bombay said:
To pull the ECU you remove the relay tray:
The relay tray is held in with 2 plastic push pins from the "front" and this annoying bolt from the "back".

Had the tray loose in order to gain access to the wire ties on the upper frame so I could remove the main switch plug from that rubber sleeve - all the bolts out on the fron but something was holding it towards the back. Didn't pull the relays, just the main switch plug. I'm sure I'll find it now that I know there's another in back.
Hmmmmm....this may be pre-mature since I've only ridden the bike about 20 miles since I installed the flashed ECU, and all those miles were with a passenger, but it now seems that the off-idle stumble is back.
Prior to the ECU flash I'd done the CJM mod and this seemed to fix the stumble and throttle restrictions. When I re-installed my ECU with the new flash I also removed the clutch jumper mod. I assumed that with it in place I would only be using the map associated with that state. The stumble is subtle but obvious and is present in both the Touring and Sport maps.
Thoughts?

Did you PM ac before you posted this? Betcha he has the answer / solution.copb8 said:

In theory anyway, the "stumble" as you call it, will always be there without the CJM. It happens as the clutch switch engages, when you're letting the clutch out. That is the point that whichever map that is chosen becomes relevant, and the slight moving of the throttle plates make that feeling. Give it a tad more throttle as you are first letting out your clutch from a stop and you will never feel it. If you had a third map made for when your CJM is on, you will notice it doesn't happen then.
Pretty much...it really depends on how the maps you chose interact at this crossover point. The other main cause is the stock bike's throttle mapping. There IS a stumble built in.scott123007 said:
I, personally, never really noticed a stumble because I'm a "clutcher". I grew up riding 2 strokes in the woods/rocks so I've always been one to be on top of the clutch.

Tomatocity,
I posted here because the title is 'Results Only....' and not just 'Good Results Only.....'. Posting it here let's everyone see and talk about all results. It's not critical and I'm sure AVC wouldn't see it that way.
Scott123007,
Are you saying that regardless of the map chosen the bike is always set to slightly retard the fuel delivery during clutch engagement, regardless of the map? And that this designed hesitation isn't accessible via the ECU settings to eliminate?
Ok, so stupid question, is it self-defeating to leave the CJM in AND have the ECU flashed?

You are correct that if you left the CJM in you would get only the maps we decided to put in your CJM modes.
To clear up some confusions before it starts...even the CJM is technically "restricted". No free control of the throttle is allowed with the CJM until 4k rpm and 30% throttle.
Can you try to pin point the conditions of this stumble? Throttle opening (wrist) and rpm?
I save every map I flash so I can review them and look into things just like this.

My last post was made while ACV was posting his so I hadn't read his response when I typed it. When street riding I'm primarily a minimum clutcher, which means I come 100% off the clutch as early as possible and let the twins torque do the work. Unless there's someone I need to get around at the light, then it's hammer down ::26:: and I never feel the stumble there.

Posting here is fine. This isn't a Vendor area. You have the flash, you posted a result. I hope you are enjoying the rest of your flash.
CJM does NOTHING for fuel. We all need to get that through our heads. Once again, THE CJM DOES NOTHING FOR FUEL.
Yamaha's fuel mapping is much "simpler" than everyone wants to realize.
The CJM tricks the bike to thinking it is in Neutral and/or the Clutch is pulled in. This LOCKS the bike into the Neutral throttle maps and the neutral timing map.
The maps I flashed to your ECU have what NORMALLY causes the hesitation/stumble removed.
It CAN be self-defeating to run the CJM with the flash, it all depends on what we discussed prior to flashing your bike.

I'll do this. I can tell you the RPM's are quite low and the throttle position very slight.avc8130 said:
I'm also going to try switching between CJM'ed and not CJM'ed to get some side-by-side comparisons. While my ECU was out and during the time it sat on my workbench wait to be put back in I was riding the FJR and maybe, just maybe, I'd kinda forgotten how the S10 felt.
Yeah, that's a real nightmare of a position for modern fuel injection...especially on this big cylinder cross-plane twin.copb8 said:
You need your TBs synced PERFECTLY to have a chance at that being smooth really.
Down that low it will also depend a lot on your wrist. My maps are sharper than stock.
See if you can pin point it.

I was thinking more about hesitation and snatchiness, and I remembered something that I wasn't sure had been posted yet.
The S10 throttle is VERY sensitive to cable slack. Make 100% sure there is no extra slack. This is easy by using the barrel adjuster right on the cable about 4" away from the housing.
When there is slack in the throttle, this slack adds a disconnect between your wrist and the motor. It adds to the on/off experience in a very negative manner.

ECU is out, boxed and labeled to you, will drop at PO tomorrow. Can you pm email address so I can forward USPS tracking message?
Well finally got the Beast out today for a 50+ mi jaunt to check out the re-flash. Just to clarify I had only 250 mi on my 2013 before having to park it and cabin fever still has the brain a little fuzzy. T mode 1-2-3rd gear lag has been totally eliminated 1-6th is very linier and smooth. Seems to have better low end torque especially in the lower gears, a definite improvement. S mode is definitely livelier since the throttle mapping is 60% twist = 100% throttle. I did notice a bit less engine braking in the S mode 4-5-6th gears which is ok since I seem to prefer T mode for town, Tight twisties, Overall driving and S mode for sweepers & highway driving (less throttle input to pass and reduced engine backing). Did not play with CJM mode. Still in break in mode so I didn't really want to flog it yet. For all the farkle money I've spent on this thing so far this is one that's on the podium. Thanks ac,

An unexpected fart is just maximum torque
Not to get off topic, but regarding the "snatchiness" off idle mentioned above...this was a popular topic amongst our FJR1300 brethren. I owned an '07 FJR a few years back and that bike had an extremely binary off idle throttle feel. ECU remapping did nothing to help it. However, a popular mod that most, including myself, had huge success with, was replacing the stock throttle tube with a G2 Throttle Tube. I'd be real interested to know how the S10 performs with BOTH an ECU flash and the G2. Anyone have both?
