    Honda r12x help needed fi & warning light

    Please can someone help or point me in the right direction, my ski ran fine until I flipped it upside down. I gor it overturned again and it ran good for about 20mins. Fi & warning light comes on constant, my ski is juttering bad & will not go past 5-6mph. Rpm will not go past 1000 either. When ski flipped it never took in any water. If I take lanyard out and let it sit for a minute or two it will runn fine for about 5 seconds then back to the usual. Turbo is good along with no corrosion on the waste gate shaft. I tried pulling codes with a jumper wire. It's giving 8,10,9,11. It's really bugging me and my friend has an f12x with same symptons. My ski is not overheating and oil and level is fine. Would sand in water box cause this to happen? Ski is always flushed and mainly fresh water use apart from the very odd time. I'm not sure if these codes could be stored on the ecu/ecm from previous owner as it will run perfect and rev on the hose. No warning lights when out of the water.

    Hi,

    I know this is an old thread, i have a 2007 R12x it has FI code 2 which has now changed to FI code 12 what should i be replacing or doing to fix? I know code 2 is map sensor ive ordered a replacement. the code 12 is an injector i think but not sure if its gone or is a result of the map sensor? The ski stioll rides but only upto 3000-3500 and max speed is 40k's any help advice would be great as ive literally just picked the ski up so desperate to actually get out on it properly. Might als be worth mentioning that the ski revs to 6000+ when on the trailor??

    Thanks in advance

    Sounds like a bad ECU

    Did it start doing this about 15 mins or so into the ride and if you let it sit it will go back to normal and do the same thing again .... That will be the ecu
