  1. Hi Guys, Just thought i would be the first to post in here of our plug & play adaptor for Honda Aquatrax F15x (turbo) watercraft. Thanks

    How did this go, did you get it working correctly?

    Hope this works with the vipec, if so I will add it to my ecu kits as a option. Keep us updated thanks Bruce

    See if this might do the job for you, not sure how it interfaces with the vipec. We use them on Honda jetskis and wire to the dash. http://www.jegs.com/i/Auto+Meter/105/5289/10002/-1

    Ecu power requirements

    So for the double up on posts bloody iPad makes it hard to edit post. I have ran theses engine on a land and sea dyno, at 15.5 psi they make 260hp at 6700rpm. The std engine produces 200 hp at 10 psi, if the tune was too rich to cause a failure there is certainly no performance issue with being too rich. Also ther is no lagging of the engine it is clean right through the rev range.

    Ecu power requirements

    Hi tony, would this only be evident on one cylinder? The afr at full boost 200 kpa is around 11.5-11.7 I would not call that too rich, yes there is about of timing but we are suffering no knock from this and the high oat is caused by ambient temp being around 25 degrees with 80% humidity. The turbo is only very small on this ski it is a ihi built for Honda. We have fitted a larger intercooler but it still might need to go larger but there is also little room in the ski. There is very little air flow in the hull as it needs to be as watertight as possible. The map pressure bounces around due to the ski coming in and out of the water all of the time, these engines get loaded and unloaded lots of times as the jet unhooks. The ski has also never consumed oil and it only runs 98 octane fuel.

    Ecu power requirements

    HI Guys, Â I finally have the ecu in hand and have pulled the last logs from it. (Please note these logs are not of the low voltage problem the ski had. These are the last moments of this engine life. Â I have also attached the PCL file for you to look at and see if anything jumps out at you. I also had a good look at the rest of the cylinders and the pistons they are perfect no pitting around any of the crowns and no lean burn either. I also tested the injector outputs from this ecu in my ski, all 4 cylinders fire perfectly. Â

    Hi Ashley, just got the injectors back from cleaning and testing all are fine, they were a little dirty but nothing too serious. I will have the ecu tonight to check logs, I don't think this tune is lean as checking plugs and log files all showv good figures when I have the ngk afx 02 sensor connected. I will check the logs and let you know Thanks

    Ecu power requirements

    By the way the ski only has a 26amp charging circuit, so.I am thinking that if the battery had a bad cell there might not have been sufficient voltage to run the rest of the electrical system as the main fuse fuse for the electrical system is rated at 30amps? I have not pulled any logs yet as the USB cable was not on hand to see if there was any low voltage.

    Ecu power requirements

    Hi I have fitted several  G4 Storms into Honda jetskis, last week I had one of my units that has been in the same ski for nearly a year burn a hole through pistons number 2. It has had the same tune in it for that long roughly 70 hours. One thing that did happen, was the weekend before the piston failed the skis battery was dead flat, it would not even power up the gauge cluster. Even after hours of riding the battery did not charge up at all. The ski was jump stated every time it was stopped. The question is does 12 volts low have much impact ont the injectors or fuel system enough to lean out the fuel table? The next weekend the ski was ridden hard at 17 psi boost and it failed at the end of the day. When the engine was stripped 1  3 and 4 cylinders look perfect in actual fact a tad bit rich, but number 2 had the crown melted away at the edge of the piston which appears to have leaned out. The far that the ski was tuned to was set at 11.7 to 1 and up till now has been fine. There is no room to fit get sensors to each cylinder as the ex manifold is water jacketed, so it is not possible to know if each cylinder needs trimming applied, however I have just had 4 injectors flow tested and they are within 1% flow of each other.the only other thing I can think of is possibly a faulty or blocked injector. I can post pics of the plugs and pistons if needed. Thanks BruceÂ

    Map Sensor

    Map Sensor

    Hi Guys, I have a quick question in relation to the internal map sensor on the storm, Is it 4kpa or 2.5 because there is no selection for the 4.0 in the software?? Â I am having trouble calibrating the internal map, as it keeps saying that it is either <5kpa or >5kpa and can not be calibrated. Â I have the smae engine running the same ECU just older and the two map pressures are different the old ECU is set to 2.5kpa. Any ideas???? Â Thanks
