    athena stage 4 map need help ASAP !!!

    hi guys

    this is my first post in seadoo section , although i have a turbo FX-SHO :P

    okay back to topic

    my friends have a 3 skis they are RXP-X 260 2013 model

    2 skis have a full stage 4 parts along with ATHENA

    1 ski is a full stage 3 parts also with ATHENA

    now on all of those skis i did the programming and downloaded the maps correctly and followed the instructions .

    now the main problem in all of the skis is that all of the skis are VERY VERY RICH

    for stage 4 riva instructions for the FPR is to set it at 58 , also stage 3 the FPR is set at 58 , both of stages uses 100 lb injectors .

    so at ideal the ski was very very rich so we had to lower the FPR till 48 psi just to get a decent ideal and good RPMs , BUT on all of the 3 skis we had a problem (plugs dying from the rich fuel at idle) so the plugs are only lasting 2 or 3 weeks , NOTE this is happening when the FPR is lowered to 48 psi .

    so i opened maya and to be honest i didnt like the software at all .

    so i opened the fuel TABLE (BFUELT) and i had to lower the fuel 25 percent so that the ski idles correctly (afr was 11.8 ) ill post the pic of the table and show you all how to lower the fuel at idle .


    are you guys in the states having this issue with athena ?

    also i started to play with the timing table (BIGNT) does anyone have played with it ? can anyone share his experience ?

    Do you have the dash logger and Lambda?

    Do You have the vent fitting on the FPR? No boost reference line connected?

    What 100lb injectors are you running?

    IMO you should try not to use the reg to change fueling, keep it at 58psi and use the software to change fueling where required. Thats what is for.
    You can also change fueling across the board by % in the EOL settings which is somewhat easier than changing the table.


    Can you give more detail on setups, or are they EXACTLY as per Rivas s3 and s4 parts list?

    Also you do realize that if you send Riva a log file they will take a look and even adjust a MAP file for you.

    Get the logger as Sayers said you can't tune properly without it

    Pointless to me to not run lambda and logging with that level of mods. You could take one dash logger and lambda kit from ski to ski to set them up.

    There's a few questions I asked above that you did not respond to and provide details for. Can you confirm those things please.

    What AFR gauge do you have installed on these skis ?

    I have never found a good way to tune an EFI motor without data logging. Things happen way too fast. When purchasing EFI tuning devices, the important questions to ask are...

    Does it have high speed data logging?

    How good is the adjustability in the SW? What can I change? And what can't I change?

    Are you hosed if the parent ECU tuning device company goes out of business?

    Ask other people how the tech support is? Get advice from people that have experience in several different systems.

    Always assume a base tune is just a place to get the motor started and up on plane and must be verified and tuned.

    Price is one of the last things to think about. Fails with almost any one of the previous points and the money you spent is worthless.

    Keep in mind that these are 1500 cc motors making about 280 up to about 400 hp. That is a bunch of HP/CI. Your motor is most likely running fuel way different than the fuel the tune was set up on.

    update :

    ok guys i played with ignition timing table in athena ecu , and all i can say is that im impressed !!! we gained a lot of acceleration and power in all of the 3 skis .

    stage 3 ski was doing 71 mph (GPS) , now its doing 76 mph
    stage 4 ski was doing 71 mph , now its doing 76 mph

    i only raised the timing 3 deg in the top end (8000-8800) rpms
    and the mid range 6 deg (3500-7000) rpms

    the skis when you drive them they were so light like a feather !!! alot of acceleration !!!

    note though : i didn't change the fuel table and it was still so rich , we raised the fuel pressure to 60 psi to see the AFR gauge what will give us , and it was soo rich that the motor was chocking from the extra fuel , AFR gauge was reading 10.3

    next time i will adjust the fuel table and i will update you guys about the results .

    the weather temperatures were very high :

    air temp : 38 Celsius
    air pressure : 999 (hpa)
    humidity : 51 %
    water temp : 34 Celsius
