    Advent w/ MicroSquirt v2.0

    Hey guys, is anyone familiar with MicroSquirt v2.0?

    http://www.diyautotune.com/catalog/m...tem-p-131.html

    I am thinking of using it in conjunction with the Advent T4 for my 2008 GP1300R instead of switching to carbs.

    Just wanted to get some feedback.

    Thanks,
    D

    I know that the MegaSquirt was installed on an older SeaDoo. I am still waiting on a response from one of the vendors and just posted a pwc specific question on the MicroSquirt forum. From the preliminary research I have done it looks like it will hook up, just has to be wired in properly.

    The MircoSquirt seems to be mostly applied to motorcycles and snowmobiles and is fully tunable. It is marketed for PWC's, just not sure how much use it has had on the water.

    Email response from DIYAutoTune

    Hello Don,

    Sure, I can help you out with this one, but we don't have much first hand experience with this sort of thing, as its not as common of an application even though the MicroSquirt was designed with stuff like your Jet Ski in mind. First, here is a link to the manual for it,
    http://www.microsquirt.info/


    It should be a pretty easy thing to tune, although I can't say for sure as I don't know what your back ground is. We've had a lot of customers who haven't even changed their own oil before buy one of our systems, install, configure, and tune the system with just the information in the manuals, online, and asking us when they get stuck. Now, I'm not sure if anyone has ever done an install on your exact model here, but the best place to ask would be the MicroSquirt forums,
    http://www.microsquirt.com/

    Here is what we recommend for most normal installs,
    MicroSquirt $400 Assembled ECU (includes short harness & tuning cable)
    GM3bar-map $64 MAP sensor
    GM3bar_piggy $11 Pigtail connector for MAP sensor
    CLTIATwPiggy $17.75 Coolant / Oil temperature sensor
    IATwPiggy $22.25 Intake Air Temperature Sensor
    38NPT-Bung_A $9 Aluminum bung for IAT sensor (Also available in stainless steel)
    USB-2920 $20 (Only needed if your laptop doesn’t have a true DB9 port)
    Subtotal without wideband-- $544


    Wideband Options—

    LC-1 without gauge $199 (you can still view real-time AFR and datalog AFR through your laptop)
    LC-1 with Westach analog gauge $258
    LC-1 with DB digital gauge $229 (available in red or blue)
    LC-1 with G series analog gauge $289
    LC-1 with XD-16 digital gauge $329
    LM-2 basic data logger with one sensor $349
    LM-2 deluxe kit with one O2 sensor $479
    LM-2 deluxe kit with two O2 sensors $669


    I think this will give you a pretty good start in the right direction. If you’d like to place an order, you can do so at
    www.diyautotune.com/catalog and it will calculate exact shipping costs (based on weight of your order) and accept all major credit cards or paypal securely. If there is anything else I can assist with, please just let me know!

    DIYAutoTune response to Narrowband vs Wideband

    Don,

    Sure, with a narrow band sensor, one can really only tell for certain whether they're rich or lean, but not by how much. For a narrow band sensor, the 12.5:1 AFR required for maximum power can give O2 voltage from 0.8 to 0.95 (depending on exhaust gas temperature), yet this same range of O2 voltages can indicate mixtures from 10:1 to 14.5:1. So we cannot use it reliably to set mixtures for full power. With a wide-band sensor, 12.5:1 corresponds to 2.08 volts, and 2.08 volts means 12.5:1. Thus there is no ambiguity over AFR and voltages. We can measure any mixture in the range we are likely to use, from full power through to maximum economy.

    Now, it does require mounting in the exhaust, which I'm not sure if you have enough on the jet ski to mount the sensor in.

    One thing that I would highly recommend doing, since you're new to this, have a read through the MegaManual,
    http://www.megamanual.com/mtabcon.htm
    It has some great information in it about EFI in general, not just the Megasquirt systems, so its a great thing for people who are very familiar with this stuff to read.

    Email response from EFI Source

    Don,

    We have no experience in the PWC market and to our knowledge you would be one of the first people we know of to try a microsquirt in this application.
    FYI the microsquirts enclosure in not fully sealed or water tight.

    Thank You,
    Mike

    Email response from Al Grippo, co-creater of Microsquirt

    Don,

    One of the early uses of megasquirt was on a seadoo turning at 20K rpm if I remember. Other early uses were on sandrails and off roading, both very harsh environments. The microsquirt is much better built than the earlier, do-it-yourself units and the Ampseal connectors are very well sealed. So with proper attention to maintaining a seal on the box there is no reason microsquirt won't work on a watercraft.

    -Al

    microsquirt forum links

    Not too much info here. A guy out of St. Louis put a Squirt on his Seadoo back in 2004. I emailed him but haven't heard back yet.

    I just noticed this thread. That was my ski. I was spinning about 8000 RPM. I still have the ski but it is now retired.
