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 '''Q:'''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. '''Q:''' 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:''' '''Q:''' 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 beside of all is mentioned: ''...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!''' ++++++++++ Update '''early 09.02.2007''' Remove c30 and able rev up to 9200 on my bench test on sound. I use Audi_270&1_4690Rpm.wav. Trigger errors is still present: more than 16/sec@7100. It becomes actual little over 6000 and most serious is ~@7000. Strange: @~8000 W counter on LCD became slower. Here is datalog: http://www.vems.hu/files/GintsK/9200Rpm.jpg Cursor is at 6528 Max peak is 9375 ''' ''With new 1.1.11 firmware is unable rev up higher than 6500 and counter jumps like messed!'' ''' This relative success achieved with 1.0.53 and http://www.vems.hu/files/GintsK/Trigger%20test_1.0.53_01.msq msq for new firmware: http://www.vems.hu/files/GintsK/Trigger%20test_1.1.11_01.msq '''Q:''' '''Plese help me with any sugestions!''' +++++++++++++++ *WikiAdvert: mailto:gintsk@inbox.lv
