Summary of change:
AUDIS ---- '''08.02.2007''' So reality is: my first Genboarded cars will be Audi 20V turbo and n/a. First '''question''' is about R48 2k7 resistor on V3.3 board: http://www.vems.hu/files/GintsK/P1260412-1.JPG http://www.vems.hu/files/GintsK/R481.jpg So becomes LM1815 output signal to uControler comes 5V high and ~3.9V low? (pullup is HW modification for AudiTrigger) --- Second '''question:''' I imitate Audi Trigger using WAW file: 270 pulses on right, 1 pulse on left chanel. 1.0.53 firmware. Everything works OK until ~6000Rpm. Then starts trigger errors. After 7000 - no sync at all. It seems thigs goes even worther with new 1.1.11 firmware. How to sort out what is cause: sound card resolution or something with Genboard? Disquiet is because '''2 of 3 Audis must rev up higher than 7000!''' # Audi have restricted turbo by rules ~300hp max. I think ~500Nm@~3500 and ~300Hp@~5000 # is project with big turbo and target power >500Hp # is n/a engine with deep modificatons for rallying ~250Nm@~5200 ~230hp@~6900 All 5L 20V using InputTrigger/AudiTrigger here is my waw files: Audi http://www.vems.hu/files/GintsK/Audi_270&1_4690Rpm.wav Audi http://www.vems.hu/files/GintsK/Audi_270&1_6840Rpm.wav 60-2 http://www.vems.hu/files/GintsK/60-2.wav 36-1 http://www.vems.hu/files/GintsK/36-1.wav I use http://www.goldwave.com/ Goldwave sound software. They have evaluation version: free and very sutable: simly loop .waw say 8000 times. And under tools is easy to control playback speed evenly. --- third '''question:''' c30 cap between primary 135tooth VR input and ground? Is't it too big?? http://www.vems.hu/files/GintsK/C30.jpg This document: http://www.vems.hu/wiki/index.php?page=MembersPage%2FTonciLoncar%2FQuestionsAndAnswers beide of all is mention: " ''...if there is noise C30 (which helps shape the input signal) may be broken, try replacing it if you don't have a scope '''1nF is will give you a 16kHz filter frequency''', you could easily have a bit more here for most applications....''" '''But 16kHz is 7111Rpm for audi 135 teeth Wheel!''' WikiAdvert: mailto:gintsk@inbox.lv
