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!

  1. Audi have restricted turbo by rules ~300hp max. I think ~500Nm@~3500 and ~300Hp@~5000
  2. is project with big turbo and target power >500Hp
  3. is n/a engine with deep modificatons for rallying ~250Nm@~5200 ~230hp@~6900
All 5L 20V using InputTrigger/AudiTrigger

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.
