time for a revisit (partially cause I was wrong concerning running tsx curves on a 2 lobe vtec k24a1)......

the knock sensitivity curve for 2 lobe vtec motors seems to be correct after all.

I hooked up a headphone amp to the knock sensor with the .1uf cap and 100k resistor like in this thread ...

damn.... so i have to choose between seeing knock threshold in the logs or my dual runner manifold working correctly.

i guess its time to swap on my stock PRB manifold i have sitting there and retune the fuel.

I have my street tuned fuel and ignition values that i have started copying in and I had to change the breakpoints for high cam fuel/ign/etc to get them low enough for the 2200 vtec point of the non performance cam setup that i still have for now. all of the parameters are changed over to what i was ...

i might have figured out why the knock threshold stayed at 0v.

it seemed to affect the PND ecu back in the day but was fixed. https://www.hondata.com/forum/viewtopic.php?f=12&t=2660

Only the base RSX was affected.

Conrad, you must remember that we start with what Honda uses and then modify the ...

yes. i was reading it while i was creating the question and searching the forum and looking at every thread where the word knock appeared and didnt find an answer why knock threshold was 0v in my logs.

the definitions of knock level and knock threshold in the help file indicate that Knock level ...

I have another question..... I see that knock level is a loggable value and its in volts.. and knock threshold is a loggable value but mine sits at 0v the entire time. am I missing something in parameters that causes the knock threshold to not track with knock sensitivity? i have "knock sensor ...

a follow up. I started tuning fuel on my CR-V today on the street using the stock accord kal. with the fueling reasonably tuned and the timing backed off a bit and an entire can of torco accelerator in the tank (this stuff is no joke.... a buddy of mine filled his 500whp dodge spirit R/T up with 87 ...

ok thanks for the answer.

time to see if a TSX knock sensitivity curve works for a K24A1.

Thanks,

Brian

No worries, I have listening device's to determine that.

While I'm new to K-pro, I'm not new to tuning turbo cars or to adjusting knock sensitivity vs rpm tables so that the knock systems still work when the block starts ringing more when the power drastically increases over stock. :-)

Do you ...

I just took a look at all the cals in Kmanager and every single cal in there has similar knock sensitivity..... except the stock k24 accord calibration?

the accord one is super sensitive.

Thanks,

Brian

Hello,

Im new to the K-Pro and tuning Honda's and just installed a K-Pro V4 in my 02 CR-V 5-speed (bone stock) and Im working on dialing in fueling. I started with the Stock K24 Accord cal because it should be close to a K24A1. on my first drive down the road at low load just seeing how it was ...
