Time to take on Kawasaki in choppy conditions! NEW VTECH tunes !!
So we all know that Kawasaki skis are fast when there is waves in the water..
But why are the Sea doo slow?
We part of this is caused by the stock ecu have a slow way of controlling the RPM and it also detects that boat is "jumping" and then reducing the power.
You can actually feel how its loosing speed in every wave.. like its almost breaking.
A stock ecu will reduce the RPM from 8040 to approx 7500 rpms..
We have spent a long time to make the RPM control tighter and faster and avoid ecu to reduce power to much.
We still want the rpm limiter there but it must react faster.
So after long testing we now have 2 version of this special tune that are now ready for public use / testing.
With these files you can expect the speed if you ski to be higher in waves / choppy conditions.
WOT from 0 will be better/safer since not so much overshoot of the rpm limiter.
So faster / safer and more fun with these tunes.
These tunes are for ALL , Racers and normal rec riders but of course racers will benefit the most from them..
These are still BETA tunes so use at your own risk! ( but should still be safe)
For skis with stock injectors and 8375 RPM limiter.
So far only for 2012/2013 Bosch ecu
You can find these in the menu system.
(if you dont then email us at firstname.lastname@example.org )
BETA 8375 Special R-1
BETA 8375 special RACE A
We want your feedback on these tunes so:
Before you test these tunes, please notice what TOP rpm you got on WOT from idle.
And how it feels like with your old tune when going WOT at max speed / rpm and compare it to these 2 files.
See how much your rpm dips in waves with stock / old tune and then compare to these.
Try too feel the difference.
All feedback are welcome, We have tested these tunes but need more feedback!

What is the difference with R-1 and Race A?
06-09-2013, 05:46 PM #3
A small difference in rpm control . I need feedback on both files .

No tune in the world will increase hook up that's why the dooo suffers the most. Lack of hook up.

dont forget about the siemens ecu guys!

Tommy, hook up isn't the only problem on the seadoo. My GPRXP hooks up like a mutha but still has the delay, i'm using the riva ecu. It's like hitting the brakes when going over the chop on each hit. From flat to mild chop all is good but when you 1st come unhooked you feel the loss when getting back in the water, then the next hit lose more till you're going 60mph and no faster and it's the most frustrating feeling! Brakes is the only description I can think of. A larger nozzle will only help recovery time to get the R's back up.

Vtech describe it well, the ECU is taking way to much control over the user.
It might not really increase hook up, but sure will make it faster in rough!

What sensors does the ecu use to know if you are in choppy conditions?
