Re: Knock control value
Ah, not obvious, but OK. So it sounds like my interpretation of what’s shown in the logs is correct; knock it detected, knock control spikes which pulls back timing, then gradually falls until/unless knock is detected again. It does that a LOT on track even with the stock tune and premium fuel. It w...

Knock control value
I understand the overall ignition timing and knock control calculations, but the actual “knock control” value used in those calculations and displayed/logged as KNK.CTRL is still a bit of a mystery. On a guess I expected to see it driven by knock count, rising when knock is detected then falling qui...

Re: OnBoard Logging Fields
I’m not at all surprised, indeed well aware and of course I log it on the dyno as we tune. My little crack was that it’s not really measuring AFR, that’s just a calculation backed into based on the remnants of combustion for a given type of fuel. Some might describe that as a fake calculated value. ...

Re: OnBoard Logging Fields
Well, I’ve had my own dyno for over a dozen years but I certainly don’t consider myself an expert in all aspects of tuning. I personally do very little tuning of OEM ECUs, a bit with Hondata but this is my first work with KTuner. Other Honda/Acura vehicles typically on standalone going back to my 1s...

Re: OnBoard Logging Fields
This interests me as well. Too bad, it would be hugely useful to log certain OBD data on the V2 while on track, and we haven’t had any success connecting both at once with a Y cable (which would be less useful anyway requiring sync with the V2 data). As for the “fake calculated” cat temp I don’t und...
