ok so i got a 2006 JDM Evo IX. i got it second hand doing 10000kms. so far i have changed fluids.

so i started logging with Evoscan and realised to my suprise i am getting 20-25 counts of knock. DAMN!!

so with the help of a very knowledgable tuner in trinidad we started adjusting timing only (no WB).WB going in this weekend.

we got the knock down to 10-13 knocks when in WOT 3rd gear pull.

but from there i tried a couple maps and the knock wont come down!!!

after seeking help ppl told me to do a boost leak test...Done! no boost leak.

changed spark plugs....good...still getting the same knock...

the only thing i can think is a bad knock sensor?????

there is one more factor that is out of my knowledge, my car is a GSR but i have a GT ECU in the car (long story!) but running maps suited for the GSR....will this cause a problem?

i can post my rom and log i did last night if u guys wanna see....i am completely lost.

did you check the knock filters in the GT rom to see if it matched the GSRs rom? that could be the factor, cause the threshholds could be off, post your rom and i will take a look at it.

What is your list of Mods? Try adding race gas or toluene to the tank of fuel and see if the knock reduces.
Are you 100% sure the ECU is GT or just the mapping? Because I have the JDM evo9 gsr also and the ROM ID is 88570008.
You have PM.

check the attachment below u will see a zip file containing my log and the .xml file.

the car is bone stock, and the rom id is not 88570008, it is 89980000...

Here is the log and .xml file. i need ur email to send ROM, its too big to post!

paste the xml file here so u can open the rom in Ecuflash and PM me ur email

Looking at your log your timing is really bad. You have 8deg at 3800 which is too much, it then drops to -1 by 4000 and back up to 11 by 4250. No wonder you have knock.

rolly1818

yeah john i was looking at that but i am no pro at this...can u assist? if u want i can email rom and xml file.

That's exactly what is going on. Your timing numbers are all over the place...


Edit: If you send me your ROM, I can tweek it a bit to get it to stop knocking....

email is thomas dot klemann @ forceprotection dot net

OK. I can have a look at your ROM. PM sent with my email address.

rolly1818

One thing I thought of also is the GSR and GT have different turbos also.

So you're using a ROM that's mapped for a different turbo than the one you have.
edit: Nevermind I just noticed you said you're running maps suited for your car

rolly1818

lol.... never knew the GSR and Gt had different turbos!!
oh well learning everyday

the only difference in turbos is they had an option for the titanium shaft and fins were as the RS's came stock with them and the GSR doesn't have them at all i think. looking at you rom it seems the def. is all fu%cked up, but that may be my computer. i looked at you timing and its really low in your rom and your fuel map looks normal at spool and then really rich, but your not even hitting really high load according to your log. i would put a stock JDM RS map on there and then see how it runs. i will check your filter settings here later and go over your rom again when i get a chance and i will get back to you.

The knock filters are correct
A JDM RS map runs more aggressive maps. The car logged 21 counts of knock on a GSR map, it will be even worse with the timing on an RS. It's a step in the wrong direction imo.
The rom might look messed up if you have a different evo9base definition to read the 89980000 rom.
