Knock sensor - Mitsu or parts store

[turbotalon1g]

So i got a longblock from nick, it has an o'reillys knock sensor in it, i don't believe in parts store stuff for some things and this is one of them.
My friend was telling me that mitsu uses rebadged stuff for their sensors, but i said i don't care its worth the few dollars to know that i am getting something that will work with the rest of the car guaranteed.

Anywho i have my old knock sensor so i am planning on switching to that.

REASON: Been trying to tune the car for the last couple of days on and off, and no matter what, anything past 10-15% throttle between 2000-3200 rpms the knock sensor basically eats its face up to 15deg knock retard.

PLAN: switch out knock sensor, double check everything is in check, pray this fixes it and maybe turn knock sensor up.

Settings are: above 20% throttle and 2000rpm.

Thanks

Aaron

I am sure the same manufacturer that makes Mitsu's stuff also makes the generic OEM replacements sold at parts stores, but I agree with you on using "Mitsu" stuff for the important parts since at least you know you're getting one of the better quality sensors since the part stores sell so many different brands (some good, some bad). Also, make sure you torque the knock sensor properly.

Agreed on proper torquing. I don't remember what it's supposed to be, but it's pretty light. If you torque it too hard it will be too sensitive and read excessive knock.

[turbotalon1g]

maybe i should try torquing it correctly first then put the other one in if that doesn't work.

Any tuners care to guess? This shit is really fucking my day up.

Swap it out, torque doesn't make enough difference to peg the sensor for no reason. I only like Mitsu stuff for sensors like that.

sweet, switcheroo countdown 10 mins.

Thanks.

I wouldn't try using anything but a real OEM sensor for something like knock. They need to be calibrated exactly for what the ECU is looking for. I can't say I have ever seen a problem for a knock sensor being too tight, maybe from being too loose.

Sorry
I would normaly put a Mitsu sensor in but I was lazy and didn't think I'd be selling the motor, don't worry I wasn't lazy with anything else. It's all mitsu except teh knock sensor. It did work fine on the 14b and stock parts. I wonder if the swap messed it up.

[turbotalon1g]

OK - Thanks for chiming in with the advice all, i put the mitsu one in and basically no change, not as bad.

I think i have Phantom knock, but i have no idea how to tell, it knocks between 2-3k.

Would you all like some logs maybe?

logs would help
