Sounds like a question for Management.
Ahhh... Well...  I think we're operating without any adult supervision.
<table border="0" cellpadding="5" width="650"><tr><td>Others have answered this above, thanks guys. Yes, the IICE Air and IICE Cool are two different things. And they work together.
If you are interested, here's a little more technical detail about what's going on inside the ECU. And what parts are affected by the IICE Air and IICE Cool
When you crack the throttle (aka: throttle tip-in) and accelerate at a constant rate, two unrelated things happen. Not at the same time, but one after the other. The IICE Cool modifies the ECU control of throttle tip-in, and the IICE Air modifies constant rate acceleration.
Fueling for motor acceleration is a one-two sequence. First, the rider advances the throttle, then second, the motor accelerates. They are two separate events, and the ECU controls them separately. An ECU controls the two events separately because the fueling requirements for 1. throttle tip-in, and 2. acceleration, are unrelated. The control algorithms to manage those events are also unrelated.
Throttle tip-in is a destabilizing event in the intake port, and requires a very complex control routine. Throttle tip-in and its opposite, throttle tip-out, upset the equilibrium of injected fuel vs. vaporizing fuel. In this case equilibrium means that the rate of injected fuel is equal to the fuel vaporization rate. A state of equilibrium is present in the intake port during steady speed and during constant acceleration. But when the throttle is moved, it upsets that equilibrium.
If you would like to read more about it, here is a relatively simple paper on the topic, Transient Fuel Control. If you take a look at figure 11, it sort of summarizes the operation. Any type of Transient Fuel control algorithm is designed to maintain a relatively constant fuel mixture during throttle transitions of tip-in and tip-out. Maintaining a constant fuel mixture during throttle transitions is a complex process based on the fuel vaporization rate, which is based on a host of dynamic variables such as Manifold Absolute Pressure and Intake Port Velocity, which are outlined in the paper.
Ok, so that was Transient Fueling in a nutshell. The control of fueling during Constant Acceleration is an altogether different thing. The control algorithm for that is simple by comparison. It's a simple air mass calculation based on air temperature and local barometric pressure. That's it. See, I told you it was simple.
The IICE Air has a simple job in modifying the ECU control of constant acceleration. The IICE Cool has a dynamic and variable task and requires a microcontroller.
The batch is going out in just a little while.
Thanks, I almost thought I would have to go after my mailman and check his bike for my ICE.
<BR>Ok, the following shipped today.
33 pieces total.
J.B., FL - addition to the previous list
Can you estimate when shipping will start for the current-ongoing AIR sale?
I don't see my name on the list. Is there a final sales list? just checking in.
Darn,Darn,Darn,its still not ready yet.Get my hopes up then drop em like a ton of bricks.
<table border="0" cellpadding="5" width="650"><tr><td>Frogy, what are you talking about dude? It can't be a surprise to you. I mean, the list from the batch that just shipped was posted on the 18th, and you replied to it on the 21st. You're just so excited, is that it?
There's only one more small batch and that completes all the 'original orders'.
You are in that last batch. Then I start building the Final Sale orders.
<table border="0" cellpadding="5" width="650"><tr><td>Here is the last batch of the original orders! I started on them yesterday, and it looks like they ship next week!
Orders for the FINAL SALE will be accepted until then!
Enjoy them before THE MAN enters the scene...
Sorry about that Chief (Maxwell Smart agent 86).I thought it was the next batch,never compaired it to the earlier post.:huh
HMMMMM....want me to DETUNE that machine of yours You better be quick on the trigger cause I plan to be first on the order this time
:huh Well, you dang well better order two if you beat me to it. If not, there will Hell-to-pay. I'll have your name officially changed at the courthouse to "Monique" before you can blink.
"Monigue":huh WTF!!! You been hanging with BigDave too much
Mine got here today thanks.
