    I am not sure how much you need, but I can say that as the high bid auction winner, I am still waiting. That may give you a starting price.

    I am happily waiting my place in line. Poolside will deliver. <label for="rb_iconid_24">[​IMG]</label>

    Just my opinion but having your bike in tip top running condition (valves adjusted, throttles synched) before making any changes like adding on a new device would make the testing results much easier to interpret. Depending on the state of your old air filter changing over to a K&N (probably the most free flowing filter you can get for these bikes) might have made a big difference also.

    That said, I am very curious to know:
    - Did your bike surge before installing the IICE Air? If so, does it surge now?

    I also have a '00 RT and when it is even slightly out of synch it surges badly!

    I can deconn the unit at maintenance. I just wanted to try it out.

    Before , yes, in first and second 3.7K and below it was like the engine blipping in and out of power.
    W/ the Air in the surge is 80% softened.
    Now more like a soft tug.

    Kinda wish I had a spare
    $550 for a kit to convert to a 2 sparker set up I saw on the 'Net.

    Yeah. Unplug, tune, try again is the best idea. When testing anything a known good starting point is the way to go.
    Not sure twin sparking is the answer. I've read about lots of them surging too.
    After a few years of playing around with this and a lot of reading my money is still on the fuel mapping. Ultimately most of the fixes are intended to prod the ECU into using a different fuel map. So leaving the bike stock and changing the fuel map itself (not easy to do) might be a good solution.
    I only know of one place selling performance upgrades that involve swapping the fuel map prom chip. I asked them about surging but have not heard anything back.

    As a point of information&#8230;
    If you move the jumper to the 0º position the ECU is reading the stock air temp sensor. So effectively the bike is running in 'stock' condition.

    UPDATE: I have ridden about 1,400 miles since installing the IICE-AIR, including an 800 mile ride varying from hot, arid, 4000' elevation desert to cooler, humid 9000' elevation mountain terrain. I'm more than satisfied with the performance improvement. I made a change from the -10 degree setting to the -20 degree setting when it became obvious it was running rich at higher elevations (and which had an immediately noticeable positive effect).

    During that ride, I averaged 48 and 51 mpg on each of two tanks of gas, which has never happened before. :dunno:dunno Otherwise, I continue to average 40-42 mpg with this bike even though I am much more spirited with the throttle. I did do a cam chain tensioner upgrade right after installing the IICE-AIR...I have no idea if that might be a factor.

    I've left it at the -20 degree setting since returning to the desert environment where it's been in the 90's, and haven't reset yet. Performance is still much improved compared to pre-IICE-AIR.

    Shouldn't it become richer as the mock temp is reduced?

    Higher altitude = less dense air = leaner fuel mixture.
    Same as... Higher temp air
    We call it "density altitude".

    By saying to use the -30 setting at cold temps means the air is more dense at cold temps so more fuel is needed to maintain the mixture. Hence the more negative the setting, the richer the mixture.

    <table border="0" cellpadding="5" width="650"><tr><td>That's good to hear! Here's a few more words about the differences between the IICE Air, and the other competitive products.

    JJ and Boxerwrench answered in the Vendors thread that the IICE Air is adjustable. Adjustability makes a performance difference but there's something more important beyond that.

    To work with the upcoming IICE Cool product, the IICE Air must be set to -10°C. If the air temperature device isn't adjustable to -10°C then it will not work with the IICE Cool.

    You mentioned that quick throttle response seems a little soft when the motor warms up. The upcoming IICE Cool is designed to address that type of issue.

    Does your bike still have the CCP and O2 sensor installed or was this removed with your previous surge fix? (potentiometer)

    The CCP and the O2 sensor were removed when the Remus exhaust and potentiometer were installed.

    I have 2007GSA. Runs pretty good except for the lug at the bottom. I sync it at 4k RPM so it is very smooth there @ 70 mph.

    Do I understand that your mod is $70?

    What does it do to MPG??

    What will be your 2nd mod?

    Ok here's what's been going on.

    I've been setting up shop to build the upcoming IICE products on a regular basis! And also, fitting in a run of IICE Airs when the current orders are filled.

    Currently there are 106 pieces left to to complete the current orders. Those are going out in 2 batches. I'm finishing up a batch of 54 pieces this week. Then 52 pieces the following week.

    After this week's batch is shipped, the Vendors thread 'buy it now' button will be switched back on for ordering.

    Great news Jim! :clap Now all my friends can have one too. Please put me down to be first on the waiting list for IICE Air's as well. :wink:
