while just cruising around and stuff knock will be at 2-4 or if it's really hot could get up to 30 or so.. but lately herre at wide open throttle im seeing like 200 or so. i run meth injection with a/f from 11.6-11.9 everything seems ok as far as a/f and everythign under the hood. plugs look decent but might just buy new ones to weed out the problems (makes sure the plugs arent fouled) if anyone knows or might have an idea of what could be wrong that would be great. thanks in advance, RJ

your getting knock that high then obviously the knock sensor is seeing knock of some sort.. How much boost you running?

you got a wideband monitering those AFRS or what it tuned for those afrs at one point?

aem wideband in my face so i can see a/f all the time.. a/f are good. its not a lean problem

wow, i dont see much knock at all unless like you said its REALLY hot(ill see 30 or so). 200 is definately not good lol

yea dude i know.. that is how mine was.. no knock ever only at idle and when i would open it up the knock would go away.. but just recently i started haveing the high knock (last week or less) so i was thinking possibly the plugs being fouled out from running rich. i've been on these plugs for about 6 months now.

well i never used safc2s knock moniter so 200 could be completly normal but it could be becuz its getting hotter. but expect higher knock readings on full thorttle anyways becuz of the increase in engine noise under full power... But it could also be some slight knock idk someone with experience with afc2 will have to help ya there.

turn down the boost and get the motor to last till you can build it. If its doing that all the time and your afrs are good, then its not sounding good for the motor. Any noise you can hear thats out of the ordinary

if your plugs were fouled and the knock was coming from a misfire you would prob. feel it missing. I dont think foul plugs will give you knock.

the way i see it is if it was a multiple missfire i would see an engine light.. i havnt calibrated the knock on the safc in about 8months so im going to recalibrate that and then get new plugs and i guess go from there.. i cant think of anything else thats why i made a thread to possibly get more ideas.. thanks all and if anyone can think of anything then let me know.

Def. recalibrate it. Its really picky when you calibrate the safc2 on the spec v. its really touchy. So ya, try that and grab some new plugs and go from there.

ok new issue.. got new plugs NGK coppers gap'd to .030 (for sti) installed them and when i got WOT as soon as i hit boost it cuts out and feels like a misfire.. so i took them out installed stock plugs (had some on hand) and runs perfect.. any ideas?

srt4 plugs arent colder than ours.. sti are. i used the pt# off the spark plug sticky page. and that pt number is for sti. im going to try to gap them like stocks and see what happens.. i was just wondering if they were too cold with the meth and all??

Like we said recalibrate it and start from there. Tell us what you see. Also what your seeing on the calibration screen for knock numbers.

at idle on the calibration screen i see 50-60 then wot i see as much as 250.. as far as the plugs not sure what the hell is going on.. im going to gap them tomorrow afternoon a little wider and see what happens.. like i said it's odd bc i throw those stock plugs in and everything is good.. runs good and strong but damn when i throw the coppers in at .030 as soon as i make boost feels like blow out or mis fire just studders.. pull them out and everything looks good.. same gap nothing contacting them.. so yea gonna gap wider and see if it comes out with better results..

Back on topic, did you rest your knock setting yet? Cause the numbers your getting on the knock setting screen dont seem to bad.

knock is based on what the calibration is set at....
Depending on the temperature outside when the car is started, the knock sensor, in the monitor screen, might show 15, or it might start out at 120. The corresponding voltages based ont eh starting voltage will vary a good bit, but will typically stay within a range of 200-250 from the knock sensor voltage the cars shows when initially started once you hit WOT. If you set the "knock range" when the initial range is low, on an occasion when the initial readnig is high, there is a good chance almost everything will show high knock.
I never watch anything other than the knock calibration screen. 275-330 or so isn't knock. 700-1000 will be audible knock. 30-190 while cruising is fine, 220-350 is fine under WOT. If your car is actually knocking the voltage will spike to the 500-1000 range or so, 800ish you'll hear knock, only heard it once.
is it possible to wire in a 500k resistor and just eliminate the sensor all together?
