Jerkiness or throttle "snatchiness" at low rpm speeds, whether accelerating or decelerating. Most apparent when creeping the bike through slow traffic. That's the rpm range where I'm thinking the Cool will really have to work on. I had not really noticed that issue on higher rpms thus, my question on your rpms.

Ok so you asked for it

RIGHT?



YES!

I see. But I'm still trying to figure out what you mean by those terms. And I hope to do that without using more of those 'colloquial' terms to describe them.

Here's what to do. Try and describe exactly what you're doing when the "jerkiness" happens. So far I'm not getting what you're talking about. I don't see how something that happens "whether accelerating or decelerating", "creeping", or "whacked the throttle from zero throttle position" could possibly be describing the same event.

For example: "Most apparent when creeping...through slow traffic." What are your throttle movements associated with "creeping".

[opposedcyljunkie]

The symptoms while creeping in traffic at a low rpm are like you are slightly opening and closing the throttle quickly and repeatedly. I liken the feeling to riding a bucking horse. I'm quite sure it is a result of a lean mixture condition, and that many others have also experienced this. It's just something that (well-tuned) carb'd engines don't do.

To ease the problem while creeping in traffic, one will have to add more rpm and slide the clutch for more smoothness.

I get what you mean. Here's something. A number of the drivability issues at the low speeds you're talking about are related to the minimum speed that the bike can travel. Idling along in 1st gear is still a little too fast for very slow stop and go traffic. The thing is, the ECU will not allow the motor to idle at a low RPM. I mean, the motor can easily idle at 600 to 700 RPM, that is to say that it's mechanically capable of doing it. But the ECU isn't programmed for a low idle like that. Fueling has a lot to do with it, but it's also the high idle speed.

No fair! Comparing the poor independent butterfly throttle EFI and emissions-tuned ECU boxer, with a CV diaphragm slide carburetted inline four. Especially if you adjusted the idle air circuit on the carbs and raised the slide needles a couple of millimeters. Really though, if it's programmed that way, an ECU fuel and spark system will outperform carbs on all fronts. Efficiency, emissions, power and drivability. Compared to carbs, an 'unrestricted' ECU wins hands down. But that's not really a comparison. A heads-up contest between carbs and EFI isn't really a contest. The carbs are so outgunned that the contest isn't fair. But, say you compare an emissions-tuned ECU with a drivability-tuned ECU. The difference between the two feels like night and day. The IICE Air and IICE Cool don't amount to a new ECU, but together they take a big step in that direction. Back to the drivability issue you described, OCJ. I think I understand the issue correctly, and I would refer to the problem as Hesitation. At least that's the ECU's part in it, the emissions-based fueling causes hesitation at throttle tip-in. The hesitation causes the "bucking" you described, but it's a secondary mechanical and suspension effect initiated by the hesitation. I'm glad we sorted that out, thanks for taking the time. I wanted to be sure we were talking about the same thing. So regarding your first question a few posts ago. Will the IICE Cool fix the hesitation problem? Yes.

I want to ask Marketing how Production is coming along. I'd like to join the discussion about how the product works but, alas, I haven't received the Aire yet.

My '11 GS includes that it's tired of pinging on tip-in/advanced throttle.

Uh, Production is 3 doors down on the left

This is Marketing where we ALWAYS say

YES!

ps in other words I really don't know the details, sorry 'bout that

Yea, Marketing knows better than to check up on Production. You remember what happened when you guys installed the surveillance cameras. I've got about 80 of these assembled up through the epoxy potting steps. I'm potting a batch of 30 on Sunday and another 30 on Tuesday. The full cure for the 2 steps takes 48 hours. The Sunday batch will be cured on Tuesday, and the Tuesday batch on Thursday.

Excellent product (work) guys but there’s one thing wrong
Remember those 70’ vintage Texas Instruments calculators smell... O the smell of new electronics
And after months of anticipation for the IICE Air I tear into the bag and sniff sniff nadda no new electronics smell But it did have a little hint of beach air




Can’t wait for the IICE Cool get it right more voc.





Never mind I forgot it’s made in California no voc
