Freestyle Need help setting up total loss

[fast superjet chase]

hi I have a dasa 863cc 8mm stroker motor with power valves and trying to setup my msd total loss up for flat water freestyle can anyone help. I need it to be competitive thanks chase.

state race gas or pump gas

Did you take at look here :

static 30 degress. start retard 5500rom retard to 16 deg at 8500rpm (Rev limit) this should be a safe place to start

It's race gas

32* static for long rod crank
start retard 5000
max rev limit 9000
max speed retard 24*
max timing all on
max retard +15 on
elec start on
start retard on
all others off

So you're running only 8 degrees of advance at 9000 RPM?

 

[Dartman]

what 2 stroke in a ski runs at 9000 pump loaded?
on the msd graft, yes
this allows for over rev on high compression setups

So why not lower the rev limit?

The lower timing works as a rev limiter. I guess it just comes down to whatever you like better.

i dont want the rev limiter to ever come on

i dont want the rev limiter to ever come on

To include when the pump is out of the water?
When I switched from B-pipe to PFP, I hit the rev limiter; so I increased the rev limit 250, but more importantly increased the pitch on my prop...

Isnt the max speed retard, the timing at the end og the rev limit? Ex 24deg max speed retard.
Then the Ignition Will be at 24deg at 9000rpm?

No. All the timing setting are relative to the actual timing your pickups are seeing from the flywheel. Your pickups may be set to 32 degrees. You can then retard up to 8 degrees from that for your base timing, so as low as 24 degrees in my example. Max retard is additional timing taken out as RPMs increase. So Dartman starts at 32. He is subtracting 24 degrees, so his advance at 9000 RPM is 8 degrees.

that is correct...
i don't think you can go -8 from base timing
-7 is most you can retard for static
