Summary of change:
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..24th'''Gunnar * '''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.

Wiki formatting: * is Bullet list ** Bullet list subentry ... '''Bold''', ---- is horizontal ruler, <code> preformatted text... </code> See wiki editing HELP for tables and other formatting tips and tricks.
