Remove the knock sensor and run it on 100 octane?

Don't laugh I know people that have done it...

 

[MADVR4]

wont the sensors ECU crack the shits if u get rid of it??? and where is it... is there a wire i can disconnect?

somehow I dont think thats phantom knock? phantom knock usually happens when your on cruise, not WOT. It seems like when your flooring it, your getting knock, and the ecu is pulling timing to suit.

what fuel are you running? What temperature was it when you were doing this log?? See how it only pulls timing in 1st and 2nd?

hey i run BP 98 or the highest octane fuel i can find...

that run was at night.. so pretty cold

tis pissing me off... it feels like i hit 3rd gear and it like... levels off... no more power to give

TD06 turbo should have more in it.... running a T-piece to make between 12-14 psi

any clues

 

[CLuTZ]

maybe your 02 sensor is dead, its not giving a reading? or are you running an aftermarket ECU?

 

[MADVR4]

yea o2 is dead... clutz u got msn add me we talk there [email protected]

cheers

the o2 should effect WOT,
what injectors do you have?

what tdo6 do you have?
what ecu do you have? chipped?

hey just stock jspec injectors...
and stock ecu none chipped...... the td06 is a hybrid made one...
has a td06 comp cover with t4 wheel but the other side is Stock VR4

i wanna get it ported =[

anywayz i got quoted $120+ for a new o2 sensor

any1 can do better would be good....

If you are running stock injectors with a td06 you are more than likely running out of fuel and getting real knock!
I'd set up your fuel system to suit the turbo befoe anything else

i didnt pay that much for my o2 sensor, i think it was about $55 or maybe even cheaper.. i got mine from bursens, u could goto global auto spares or who eva is local, 120 is pretty steep tho.

yup, thats definately real knock. Are u logging injector duty cycle? Plus u might be hitting fuel cut as well with a stock ECU.
