2014 stx 15-f ECU flash (ANYONE)
Looking to get my STOCK 15-f ecu flashed to a higher Rev limit.
The 2014 is not the same as the 2012 and earlier.
Not looking for timing, have the SATO slotted trigger to do that.
Any info would be appreciated OR an alternative.....

I think he has a 14 ecu and wants more revs. How high do you want to spin it?

I have a 14 and need more revs.
Looking for about a grand or so, nothing major.
Working on pump cone and props now need just a little more.
Don't need any timing or fuel seeing the motor is stock, (kinda)
Suggestions would be great.

Yeah... A grand on a stock motor wont last. I spin my motor to 8500 hard limited with forged internals and much stiffer valve springs and thats pushing it. My operating rpms are set at 8200 but I run a full standalone.
What have you altered on the motor? The stroke on these things does not make them really condusive to spinning them high and staying together.

The plan this winter is for FORGED pistons (12f) and a deck lift.
Full spring set equiv to the 310r with aftermarket valves.
Cams (possibly worked lobe's on the stockers).
Isolated water routing with visual over boards.
If I can get another 5mph I would be happy.
So I would say if there is a way to get between 500 - 1000 rpm's I should be in good shape.
If to high I can adjust down with prop work...

Just so you know, there isnt really a gain using the 310r parts, they are the same, just different materials, to keep the motor together I would keep the rpms under 8600 hard limit. You know you will need race fuel woth the 12f pistons, they put the compression at like 14.5:1 in a 15f motor.

Race fuel yes, gonna ms 109 prob.
As for the 310r parts, both kanamori and warner said it was the way to go.
Same as far as type, but stronger materials due to heat from sc system.
And with the 12-f forged, my deck lift will be at 13.9-1 comp ratio with a custom base gskt.
This will be a secondary motor set up, the original motor will stay stock......
Thnx for the info

Tuning this motor isnt going tp be as simple as keeping the fuel curve the same and just adding rpms. The second you add cams into the mix the stock tune is gone.
