Hello,

Main issue:
I'm having issues with advanced protection activating when it seems like it shouldn't based on what I have set the conditions to. Every log I've recorded post updating to 4.1.5.0 has instances where it activates, where as before, it didn't.

My first calibration and data log (08-18-1000), I have only one condition set to:
Oil Pressure < 20 "/psi
AND
RPM >= 3000 RPM

In the associated log, you can see it activates pretty much anytime pressure drops below 20 "/psi

The second set (08-24-1715) I have 2 conditions set:
Oil Pressure < 20 "/psi
AND
RPM >= 4000 RPM

Oil Pressure < 5"/psi
(Left the remaining fields blank)

The associated advanced protection issue log shows it activating pretty much randomly.


Second issue: (see "Fuel Cut Issue" log)
I'm getting fast on/off surging at low throttle. I would assume something with my overrun cutoff needs to be tweeked, but I'm not understanding how just yet. My Overrun cutoff (low cam) is set way lower than when my injectors are cutting off.

Never mind on my overrun issue. Did some poking around and looks like most with K24s set all the fields in the low and high cam overrun cutoff to 15 kPa. This fixed my overrun issue.

I understand the concept of turning off the injectors under a preset manifold pressure, but I have not been able to find a good description of what the difference is between the low and high cam tables in KPro. I read "low cam" to me means when the low profile cam is being used and "high cam" when the high profile cam is being used. Is this correct?

Change your analog input unit to 'psi'. On the second protection set the second term to 'AND rpm > 0'.

Made the changes suggested, but still having an issue with advanced protection activating outside the conditions I have set.

My conditions are:
Oil Pressure < 50 psi
AND RPM >= 4000

Oil Pressure < 20 psi
AND RPM > 0


When cruising around 3500-3700 RPM it seems to activate anytime my pressure drops below 50. Lower RPMs, it's pretty much random.

It is because the oil pressure input is mostly intermittent.
