S2 Cutting Out Issues
#23
I agree, the pressure sensor and relief valve are the likely obvious culprits... it's very unlikely to be anything else I think.

You can watch both 'ECU' values on PP so I'd just watch them while it fails.

Or better still get a decent multi-meter and log the actual voltage from the pressure sensor, log a failure event.

Then do the same on the duty cycle from the relief valve.


It is a weird one because if the RP drops it'll make the valve close up to increase RP, but if the sensor is reading low any way, then how does it know to cut out?

So it might be a half second or second where it reads low, then returns to normal to see the RP has risen massively, and so cuts the injections.


If you log the actual sensor and then the sensor feed at the ECU multi-plug (possibly at the same time), then you could assure the ECU is seeing the same signal as the sensor is seeing, and look for any odd readings around failure (ie, a dip before a sudden rise)


Hmmm
