Trying to Tune...

[qnz]

the eclipse knock sensor is more sensitive than the evo knock sensor. I used a eclipse one before and my knock light would keep going off. I swapped to the evo sensor and it flashed maybe 80% less

All, just want to apologize; I got fed up last night.

Anyways, that's an interesting observation. I've been reading on DSMTuners that someone tried to swap out their knock sensor with an Evo one but it made no difference.

In addition, I don't think anyone over here on Club3g is using an Evo knock sensor, is anyone?

My assumption is that it has to be something with either the Evo knock filters or the sensor itself; I'm leaning towards the knock filters.

If I switch back to my 3rd Gen Ecu, which ROM is most compatible with it?

do you have bad lifter tick?

[itz_tha_dre]

I do not have bad lifter tick.

I'm going to try regapping the plugs from .028 to .024 and see if that makes a difference.

Edit: Nope. No difference. Maybe I'll try from .024 to .02.

[johnsgalant]

try removing the knock sensor and revving see if it still 30+.. try unclipping the connector to the knock sensor and rev the car dont drive it around.. see if u get any knock..

[2000RS-Turbo]

No gap is not the problem. I think what you need to do is set the knock multiplier able higher. The only other machanical things are your timing (as in timing belt), bad coil(s). If you have new plugs, wires, clean/flow tested injectors.

[itz_tha_dre]

Johnsgalant,

How is the ecu going to detect knock if the sensor is removed/disconnected?? Also, what I have to do is what you suggested a couple posts ago; use ScanTech to check my sensors and all that stuff. I totally forgot about it until now.


2000RS-Turbo,

I'm just going to try it anyway; what have I got to lose? Haha, although my knock did go down a bit just revving in neutral after I gapped it to .024; I only (lol @ only) got a knock count of 17 at the highest.

Also, it more than likely can't be my coils because awhile back I got new ones because I thought they were going bad. I switched them with my old ones recently and the same result; so I just put the new ones back on.

If after doing all this it still doesn't fix anything; I'm going to have to have someone physically check the belts because I did do a timing belt change awhile back. Or is there a way for me to do it myself? Or would it be too difficult?


Thanks for your responses, again.

[2000RS-Turbo]

checking your timing isnt that difficult it just is gonna take some time unles you have a timing light. You can either use a timing light or check the marks which means doing everything you would when changing the belt. But Im gonna say you probably just have a noisy motor and will need to set the knock multilier table for low and mid rpm higher, i would turn up the high table just incase its real knock. But i doubt it is.

Just tried to see if it was my EGR (reading this thread got me thinking about it; Disabling EGR and fuel pressure solenoids - Page 10 - evolutionm.net)

After disabling it, nothing happened; same counts of knock.

I'm going to do a boost leak test next because I don't think I'm vacuuming correctly.

What do you guys vacuum at? I'm seeing -15/-16 vacuum from the brake booster line. Is this correct? I've seen a picture of someone at -20 for vacuum, so I'm thinking I might have a big leak somewhere.

my car was always at ~-22 off the fpr

Interesting. I'll have to look into the vacuum leak as well I suppose.

Also, do you have your EGR enabled or disabled? I came across another EvoM forum where they discussed disabling it because of timing issues. (Disabling EGR and fuel pressure solenoids - Page 10 - evolutionm.net)

[johnsgalant]

i was curious to see if u would get knock with the sensor laying down somewhere off the engine block but still connected... did u ever do a compression test?

Yes! i found another thread someone started that explains how to disable other annoying things as well.

Interesting. I'll have to try that as well just to see if it does knock. If it does, then obviously theres some sort of interference.

Haven't done a comp. test as of yet, I know I really should, but haven't had much time to. (haven't really been driving the car lately, either)

I think I'm going to follow these steps moving forward to diagnose the problem...


1. boost leak test/load Tephra v7 ROM
2. undo some wiring that I've done in the past (radio, o2 sensor heater wire, gauges, HIDs) just to see if I did something wrong.
3. As johnsgalant suggested, unplug knock sensor just to see if the ecu still sees knock
4. Compression test
5. If all this fails to provide any insight, have my actual timing checked out.

Anyone else have any suggestions that I could possibly go through?

its not real knock and you need to raise the knock mulitpier tables.

I have before, but it got me thinking.

Did you or anyone else have to adjust those knock multiplier tables? From what I know, no one else really had to do that, which got me thinking, why is this happening to me and not really anyone else?

I want to be 100% certain its not real, and if I have to check every single possibility, I will, before permanantely dismissing it as phantom knock and raising the levels.

Sure, I've raised it before, but the knock was still there, just nullified. As stated before, this really isn't a solution (unless it is 100% phantom knock), but rather just a bandaid; I want to be sure of it.

[Ithinkyou]

I never had to mess with those multipliers either you could try this hex for starters. If your ecu is still hittin 36 then youll know somethin else is faulty.

Change Periphery0 to

>>>0x5658-no rear O2, No knock sensor<<<
56D8-no rear O2
5698, no front or rear 02

Change Periphery2 to 0x0DDF

- Changes a few things to not supported within the obdII scan when you get your car inspected , and allows you to clean up all the little vacume lines and solenoids hanging on the back of the intake manifold. It gets rid of all these CEL's P0443 , P0446 , P0403 , P0243 , P0090 , P2263 , P0450 , P0451 , P0452 , P0453 , P0441 , P0442 if your throwing any of them...

Change Periphery3 to 0xC0C0
Change Periphery4 to 0xFE00

Now the wastegate solenoid and fuel solenoid are disabled in the ECU. Without this step you will trip codes P0243 and P0090 for the missing solenoids.

I wish i could find what hexes relate to what periphery bits that would be great cuz you could knowingly turn all kinds of crap on and off for your own personal setup.
I found this on evo in less than a minute plus some other stuff but i wont post it. I will clue that the guy dropped a 3g motor in a lancer.

[itz_tha_dre]

Oh yeah I forgot you could turn off the knock sensor instead of unplugging it.

Good call!

Is that periphery bit for the knock sensor/rear o2 in F9A? -ah wait I think I have to add those bits back in; I don't see them in V7.

[johnsgalant]

at 36 counts i would assume u can hear the pinging but if u roll on boost slowly. WOT u wont hear anything and ull go boom so careful.. I wonder if u still get a reading if u disable the knock sensor? I am using a knock sensor off a diamante and i can tune the knock out.. QNZ had an issue where his knock sensor wasnt flush on the block and gave us a lot of knock maybe urs is too loose or too tight?? Try tightening or loosening the sensor.. Did yours have a sensor stock?

[2000RS-Turbo]

I had to raise the low table and mid from lifter tick reading as knock. Someone on evom said to raise them until you rarely have knock when you are just reving it if you believe its phantom which i think yours is

Yeah i found a map on evoM done by MrFred(ecu guru). I documented them in the Tv7 thread.

[itz_tha_dre]

Well, I haven't updated this in awhile.

Just to let you guys know, I'm currently having a clutch problem so the car is going to sit for a bit until I can get that resolved.

Slave/Master Cyl. or Clutch?

In the meantime, wish me luck... since I've been having none whatsoever.

[qnz]

where did you screw in your knock sensor? theres 3 possible spots that you can screw the knock sensor into. Maybe try switching up the location? Also, have you checked your ground for the knock sensor? My HKS knock amp, which is spliced into the evo knock sensor goes grazy at 70-75 mph. It constantly beeps, telling me Im knocking whenever I am traveling 70-75 mph. The evoscan tho doesnt register any knock.

[Ithinkyou]

Tip in knock is solved by doing the following.....

The "Knock Load" table
Raise the 2500, 3000, and 3500 rpm load values by 10.

Phantom knock is resolved by first fixing any mechanical issues then.....
Lower the "knock sum decay timer" to = 80
raise the "knock multiplier" low and mid by one or 2 points.

I just read that on evoM FYI!!

[itz_tha_dre]

Well, I'll just have to try that once I get my car back from the transmission shop.

Have you tried it ithinkyou? Also, do you have a link to where you read it?

[Ithinkyou]

na, my issues gonna be totally different now. Ill prolly have alot more valvetrain noise, plus i got motor mount inserts, deleted balance shaft. Im sure ill have much more non-knock noise for the sensor to be picking up.
The guy that wrote it's name is Applaud. Hes pretty knowledgeable in the ecuflash section but i was bouncing around alot that day looking for info on MBT timing an saw him mention that to someone.
