I'm just going through 12P now, Spark Reference Angle is ~70deg in the stock V6 bin. Does that mean spark is set to 20deg BTDC? (90-20=70?)

[festy]

It means the CAS reference notch signal is at 70* BTDC. It does the same job as the missing tooth in the 36-1 or 60-2 trigger wheels.

12P was based off code originally used on cars that had hall effect modules rather than reluctor. on a hall effect module, the spark fires on one edge of the trigger blade (10 deg) without the ecu there, but when its in EST mode with the ecu controlling timing, the module sends the other edge of the tooth to the ecu as its reference point, which is at 70 deg.

on a camira/pulsar reluctor module, the module mode spark of 10 deg and the EST mode reference pulse of 10 deg are the same, and you use 10 deg as the reference angle. when the reference angle is less than the target spark advance, the ecu actually counts forward to predict where to fire the spark before it receives the reference pulse.

[BennVenn]

How does that relate to a reluctor based setup where the trigger is set at 10d btdc? Should I be setting this to 10d?

Single fire option - This should be enabled because I'm injecting every trigger pulse, and there is no 'inbetween' trigger?

for the single fire mode, this is a quote from the guy that made 12P:

Yeah it wont have double fire in TBI mode, it fires on every pulse so it cant skip a few between injection events. To be totally correct you really should set it to single fire and then halve the kinjflow you have now - it should end up being the same injector PW as youve got now. There wont really be any difference in the running of it but will take out an extra divide function which is open to math rounding errors.

[BennVenn]

Man it's frustrating when you hit save after changing a value and it jumps down to the bottom of the parameter tree.

[Jayme]

yeah you learn to work around it. it jumps to the last one you opened that is still open. so I tend to open something random nearby where I want to stay and leave it open so it always jumps back to that. also when you are emulating with OSE plugin, the save button doesnt close the table, it just uploads that table direct to the nvram and stays open.

Ahh I was wondering why it went to where it went.

I've transplanted the VE to 12P, aligned 800rpm to 800rpm etc. I'm left with columns and rows of 0's. Is there a function to interpolate the knowns to populate the 0's?
Smooth @ 0.5?

Just go to 3D view and smooth it manually.
