bassn_07

I monitor knock on my car with my Dashdaq/Zeitronix and I get the reading in voltage. What would be acceptable voltage numbers in regards to knock? My numbers will fluctuate between .02 - .06, this both during idle and at WOT. I had no idea what safe values to use but I put 100 octane gas in my car with my 91 tune. Doing this allowed me to see what numbers I should be using and what's typical for a run with no knock, I am assuming that I'm not knocking with 100 octane gas. My results were the same as my WOT runs with 91.....

I've done this a while ago and after reading a few articles it just got me curious to know what values are acceptable.

i have no answers on the knock voltage, but how did the 1-step colder plugs work out for u?

I still haven't installed them yet. I'll hopefully get it done this week and I don't foresee and problems.

While I hate to resurrect an old thread I too have the same question. Are you able to monitor knock with the Zeitronix successfully? Or are you having to use something like a Vishnu Knock Buffer in tandem?

Can we not log what the ECU is seeing as knock ?

Has anyone with the dashdaq/zeitronix combo been able to successfully log and filter the factory knock sensors to be able to provide a useful analysis? Or is an aftermarket knock sensor/logger the only viable option?

Aftermarket is the only viable option, I tried with the zt2 and it just doesn't work, actually look at other threads from bassn and you will see it never was working 100%, don't waste your time

Bummer

If you log all parameters real time and then only use the timing via obd you will see very clearly if there's knock, if your timing is at 17* for example and then it goes down to 4 or 6 for example, that's knock

Good point
