I missed that, but for now I'm going to leave it with VTS, seems to be working OK.
But now, I have another issue:
On the same ocasion, I also connected a Phormula KS4 knock sensor (http://www.phormula.co.uk/KnockMonitor-KS-4.aspx
) to analog input 1 in S300 (I had to mount the 0.1uF capacitor in C42). This knock sensor displays the engine noise as a 0-100 value and outputs an analog 0-5v output to connect to logging systems. It was working, I was able to immediately pick the KS4 signal in smanager, showing a minimum 0.2v and going up as engine noise increased.
Problem is, after a few minutes, the signal from analog input 1 in s300 gets lower and lower, and eventually will stick to zero, even when the KS4 displays high noise levels. I mean, after 5-6 minutes, I get a fixed 0v analog input from s300, no matter the value displayed in KS4.
Turning ignition off and on doesn't cure it, but if I try again the next day it will be fine for another few minutes, but will get stuck to zero after a while.
I hope any of you s300 experts could tell me what is going on, and what I can do to fix it.
