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?

G2?

Well, had a nice talk with avc last night and mine is on its way to him. Looks like I will be a bit of a guinea pig as he will be doing a map not previously done. Since I tend to not be real aggressive when just out for a cruise on the back roads and need to keep my license clean, (CDL) after we talked it was settled to try the following:

• 
  T mode - half way between stock T mode and the avc version
  S mode - his normal T mode flash
  CJM - his normal S mode flash

This way I'll have access to everything he normally does and less but still more than stock. Didn't see much use for the stupid aggressive map he's been putting on the CJM so this should be good. Report to follow once I get the ECM back and put all the other goodies on the bike.

Fuel injected bikes all seem to have a snatch about them, guys on the Triumph Tiger 1050 forum use to switch I think Speed triple or Daytona Tubes to solve the snatchy throttle response.
Someone on this forum modified his stock tube.

Looks like a nice compromise, can't wait to hear what you think of it.

I recently re-flashed my ECU (more development is always underway) and I successfully CREATED the "stumble" pulling away from a stop.

I am 99% sure the "stumble" is from the stark transition from the neutral/cltuch map to the 1st gear map.

I left the stock neutral throttle map, and installed my "enhanced T". There is definitely a stumble at ~2k taking off. Crossing the 2 maps, it appears plain as day that the throttle "jumps" maps as the clutch switch disengages and this makes the "stumble".

So, depending on what is chosen for the CJM map, this stumble might exist.

Knowing that now, do you think that your flash cures that particular issue? You recently did mine, but I have not had a chance to ride it (#!%@ snow!!). Mine had a pronounced stumble before the flash, even after syncing the TBs and adjusting the throttle cable slack, which is what drove me to run the CJM.

It really could depend. Since every flash is custom to the rider's desires, if the maps you chose for CJM and the "regular" ride modes have similar off-idle response than THAT portion of the issue would be "fixed".

A couple of weeks ago I happened by a BMW dealer (the closest dealer is over 3 hrs away) and stopped in to see what all the fuss was about on the new 1200GS LC. I came away impressed. It has nice handling and the engine is very responsive. Made me even consider trading my Super T in. I love my bike, but it has never felt like I thought a 1200cc bike should. By the time I got home the fever had subsided, I really like having a super reliable bike and great dealer network and super local dealer too. It did get me longing for more though.

So I sent off my ECU to ac last Monday and hoped for more performance. It was back by Saturday (Thanks for the quick turnaround). The hardest part of reinstalling was just hooking the battery back up around my crash guards. That stupid little nut on the positive electrode just wouldn't stay still. After a small shower of sparks (I believe now when I hear stories of emergency welding with batteries) I finally got it to hold still long enough to get the bolt started.

On Sunday I was able to get a 40 mile ride in before the snows came in (spring in the Rockies). WOW what a difference! In T mode, it is smooth and responsive in all fears now. It revs so strong I was at 6k rpm in 2nd gear before I realized it. In S mode I love the snappy response. There is slightly less engine braking now, so I love the burbling as you are slowing down, especially in the upper gears. Overall couldn't be happier. This mid made the Super T the bike I had always hoped it would be. Thanks ac!

One tip for the battery nuts: fold a small piece of cardboard up and jam it behind the nuts to push them to the top of the terminals.

That burbling is most likely since the injectors are still fueling on decel now. I switch that on in an attempt to further smooth on/off throttle transitions.

I'm glad you are liking the flash. It's pretty fun having what Yamaha locked away from us initially.

One way you might find out if its a map jumping issue would be to load the same map for T and S and see if it goes away.........ya think?

Yup...correct.

So the question becomes: what is it worth to have 3 modes? The stumble is easily avoided in my opinion.

Another tip is to hook up the positive terminal FIRST, then hook up the negative terminal. That way, if you ground your screwdriver while trying to tighten a terminal screw, there will be no sparks.

Haven't set my throttle adjustment or had the TB's synced yet but today I put it in Sport mode and when I pulled off from a stop I held a constant throttle and eased the clutch out until fully engaged. You can feel a very distinctive pause in the fuel delivery at a specific point in the clutch release. It's repeatable and consistent. It's like Yamaha programmed a slight retardation right at clutch release but for what I don't know.

I haven't had time to put the CJM back in and ride but when I do I'm sure this will be gone again since the bike won't know where the clutch is. Quick question. When the CJM is in place does this mean it ignores all settings stored in T & S? Is it an either/or or does it just affect certain aspects?

With the CJM the ECU is "stuck" in the neutral throttle and ignition maps.

Ok, so that's what I expected. Now, if I put the CJM back in and the stumble is gone wouldn't that lead us to think that the throttlebody sync and throttle cable slack aren't the issue? Would it then be possible to look at the S & T mode settings for a given throttle range and set them to the CJM settings?

I am not convinced the slack in the throttle cable will cause the stumble. Throttle cable slack has more to do with "snatch".

Throttle body sync is definitely a good practice and one of the things that must be squared away before you can fully diagnose.

Sure. But if I set S and T mode throttle ranges to be the same as CJM...then you get the same maps.

As I have said from the start, the flash is an evolving project. With the latest development, I have been working on this issue.

One thing that becomes and issue is the human interaction. The EXACT way each rider commands both the clutch and the throttle create many variables. Even the clutch lever pivot setting is a variable.

Sent mine out to avc on Monday and hadn't got tracking from USPS, he PM'd the number Friday and said he was a jerk - wouldn't be here till Monday. Well, I beg to differ, USPS and I say it ain't so, ecu arrived in today's mail...........west coast to NJ and back in 5 days, pretty dammed fast if you ask me. Will have a report on how it works once I get everything put back together.
thanks

Finally got to ride my brandy new S-10 today for the 1st time since the test ride at the dealership in November - but, this time it had the reflashed ECU in it.

All I can say is that I'm glad it is no longer neutered! AC, My dog wants to know if you can de-neuter him too!!!!!!!!!

Just what I wanted - 1:1 throttle input to throttle output in T-mode and a progressive ramp up in S-mode. I forgot to bring along a mini fuse to check out the 3rd mode - something to look forward to!

I got about 125 miles on today and couldn't be happier. And, BTW, I don't notice any off idle stumble like I remember from my initial test ride - If I remember correctly, someone complained about an off idle stumble and AC said he would address it in future flashes. Mine seems to be just fine!

Bottom line - money well spent!

Thanks again AC

Jim,

I still don't understand why Yamaha chose to use the clutch switch as the map actuator. At any rate, having a "neutral map" is questionable at best, and using a clutch switch to change that map to whichever one has been chosen when letting the clutch out, mid stroke, is retarded.

Sorry AC, for the hijack, just had to get that off my chest. LOL
