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:
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 turbo restricted 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
here is my waw files:

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.
