anyone have a read on a riva tune or modified tune for seadoo?

[kaineoutlaw]

just wondering if someone has a riva tune file for a seadoo or any modified files? everyone claims riva gets better fuel economy but looking at the commanded af, i feel like seadoo is lean as is. i am used to automotive tuning tho, but the commanded af for a supercharged engine of any kind is normally richer than what i see in the seadoo tune. mainly mid throttle and rpm. so id like to see what everyone else is doing to the fueling. since there is no o2 sensor, im reluctant to even adjust it. guess youcould tap the exhauhst for one but w all the water in the exhaust idk how a wideband would work really lmao

the stock tune for a 300 is lean to begin with.
Riva is tuning via injector PW, not VE...
if you have access to the Riva map editor you can just copy the injection correction table into HP tuners.

I don't feel the way they're doing it is the best way, it works, but I feel tuning VE table is the "proper" way.
of course, you'll need an O2 sensor installed in the exhaust maniforl if you want to tune it with VE.

You could read the .bin on any ecu, then convert to HPT file & read that way

how do you do that?

[MRRPMBRP]

Use any software that will read the .bin then use HPT file converter to convert

like ktag or something like that? wich pcm uses this aplication?

There are many computer programs that can read a .bin file, pick one that you like.

Really is that easy? I and the definition we're they get it??

I Don't have a file. You can tap the exhaust and do a single test. Once done take the sensor out and screw on a threaded cap. I do this on my builds. Once the Afr is set l, it's set. If you're not a builder then leave it in it should last a year or so.

I have dashPac on mine, so I'm always looking at AFR's.. LOL

How are you extracting it from the ECU?

As far as the Riva tunes they mostly use the injection correction table and keep the lambda stock. So it is lean.
