Hondata Knock control study

All testers, could you please weigh in on the Knock control values in your vehicles. This will be useful for all Accord users in this forum.

Firstly, install on your mobile device. and connect to your FlashPro. Take a screen shot and post here with
Vehicle (10AT or MT)
Tune (Stage 1 2 or three)
Fuel supplier (Shell, Arco etc)
Octane
Knock Control %

If you are really advanced, take a datalog with FlashPro of a 0-60mph run then generate an XY chart of RPM vs Knock Control. Here's a quick 60 second video on

Ok, I'll start off with two Accords,

Accord 10AT
Stage1
Mobil
91 California
54.69% Knock control

Accord MT
Stage3
Shell
91 California
62% Knock Control

I have a 2.0 touring AT and Iím running stage 1
I love the throttle response with the mountain of low end torque that just pulls u back into your seat. Then the midrange kicks in with even more pull. FYI the rapid changes in the AT tranny make this accord accelerate with no interruption and with the added tq and hp the tires chirp in what seems like 1,2,3,gears. Gears change so quick it might possibly chirp 4th too.
Changing back an forth from eco mode (oem tune) and normal (stage 1) Iím able to tell the difference and itís night and day for me. (I canít imagine what the MT folks feel in stage 3!)
Iíve done lots of pulls on the freeway and up a local mountain pass for the last three weeks now and havenít seen knock pass 62. In regular driving it hovers around 56~58. I live in LA and itís been around 85 degrees lately so itís seen some heat.
This tune has changed my car and I love it even more now.

Vehicle - 2.0T 6 speed manual
Tune - Stage 2 non CARB
Fuel Supplier - Esso (Canada)
Octane - 91 octane

iOS or Android? If Android can you test with an iOS device?

Great graph. Very flat all the way through the rev range. Turbo Civics typically see an increase in Knock control above 5500 rpm due to back-pressure in the turbo. The Accord does not which speaks very well to the design of the turbo system. You have maximum engine performance to the redline with our tunes. This indicates the tunes are not stressing the engine.

This is really good - and you are running Stage 2 with 370 lb-ft torque as well. Tha'ts fair amount of cylinder pressure. If we were going to see an increase in knock level, it would be with this calibration. The cold Toronto air has to help a little bit. 54% is about as low as this will go. When we first picked up our MT Accord, it was running 87 octane with a knock control of 100%.
