Mike, why shoot down anyone who offers tuning advice in the interests of your own, rather shameless, self promotion? Do you realize I post under both Hondata and dstevens?

 

that was not my intentions and i apologize if i came off that way. I've thus edited my post. Thank you for catching what I wrote & I Didn't know you were Dstevens! Now for my questions

What is the reason to only look at knock count? Knock count increases based on noise the knock sensor picks up. So it could be ghost knock, right?

 

you can adjust knock sensitiivity with flashpro! One of the things k-pro should have

 

I just checked that out, I missed it the first time. Definitely a great thing to add in there when working with a stock motor S2000.

You want to worry about knock count instead of knock retard because if you read the post linked above, when the ecu sees knock at say 4000 RPM, it will apply a knock retard the whole way through the RPM range, not just at the point where the knock was recorded. It will do this even if the knock sensor is no longer picking up anything.

So essentially you want to limit knock count throughout the RPM range, and in return you will have a lesser knock retard.

 

thanks for the clarifications. I guess the knock sensor is engineered a different way compared to a k20 knock sensor. That's where I was wrong and I admit my wrongness. My apologies to Hondata (derek and doug) and to the s2k community.

Less knock count and retard, the better! Right?

 

Exactly.

What I mentioned above is definitely a simplification of how the knock control system works as a whole, but should be easy enough for most to understand when starting out.

Hondata's post up above has some good info in it.

 

Hondata's method about removing knock and helping the rest of the powerband didn't hold true on my clients car today on the dyno. Maybe it does on others, but it didn't on this car. Lost power when adding timing and didn't lose when removing 2 degrees from the knock areas.

I'm not saying they are right or wrong. I was just stating that it didn't hold true on this particular motor.

 

whats the most ignition degrees most are using around 7-8k? my map has around 26

 

I am not sure what you are getting at with this. Did you mean didn't gain when removing 2 degrees from the knock areas?

Did the knock go away when you removed timing from the car? How many counts were you seeing? What was the knock retard level through out the powerband?

I am not really surprised that it lost power when you added timing to it.

 

i really appreciate the help with the knock, my tune is looking clean no knock and keeping my WOT a/f around 12.5-12.7 this sounds good to me but im very new to tuning. the reason why i mentioned the question above is because i was wondering if there is anymore power i could eek out with ignition timing. i wouldnt mess with the timing myself but my tuner said he could mess with it but if theres not much to play with i was thinking of keeping the tune like it is for a few months until i boost. please any advice would be wonderful
