VEMS Round Fuel pressure alarm output feature request (+ VT ini change. Under evaluation).
- VT ini August 2nd - Gunnar
- simple numeric entries (
- firmware + 10days (~August 12) - Marcell
- test VT +5days August 17 - Dave
- upload / confirm August 22..24thGunnar
- Analog 1 = MAP note: button-press might effect this value
- Analog 2 = Fuel pressure
- Speed = Tacho = RPM
- Threshold curve (X=RPM, Y = Fuel pressure/MAP threshold value)
- appr. 0 .. 4 range would be acceptable or rather 1..5 range more reasonable ? (8 bins fixed 1000 RPM or max 16 bins with fixed 500 RPM steps should be perfect)
- eg. activate output if (Analin2 < Analin1) or (Analin2 - Analin1) < Analin1 * Multiplier_threshold(RPM)
- To be able to activate a LED / light when delta fuel pressure goes below a certain threshold
- no problem, if LED lights on/off temporarily while button is pressed (on round to switch display slots)
- for a rally car so there is no chance to be staring at gauges while flying through forests/mountains etc.
'''Why is it a ratio (or multiplier) ?
- Normally FP = MAP + 3.8 bar (appr, based on some mechanical fuel pressure regulator),
- and reasonable to activate warning light when FP < MAP + 3.3 bar or so...
The right comparison is Value1 - Value2 = EvaluationValue
Then OutputLed = if EvaluationValue > ThresholdCurve
I have received the gauge so I can perform the testing at any time.
