What is that sensor that you can adjust mounted on the left front strut tower? I vaguely remember someone saying it was something to do with the fuel mixtures.

It is a bosch the number is 0280101012

This mounted on all hyundai lantras/elantras I have seen.

If it does adjust fuel mixtures then surely we can run high octane and lean it as long as it don't det and may give a fraction more power and better fuel economy.

I have access to a dyno but the car this is on is not currently in a dynoable state.

If it is what I am thinking, I can test it later on in the year and let you guys know what differences it does.



Or Am I just wishful thinking of an easy tune and it does nothing?

 

Lol its our knock sensor

No such animal as a cheap way to tune

Cheapest way I've seen is back in the day I found a buy one get one free coupon for the smt6, me and patreezy iirc split it 50/50 and I don't think either of us ended up actually installing it lol

 

That is the acceleration sensor, long story short it tells the ecu about the state of the car's body, so it can filter out phantom knocks caused by potholes or rough pavement/gravel roads.



Rest assured, I am still working on getting the ECU's tuneable.

 

Its not the Knock sensor that is mounted at the rear of the engine block.

Acceleration sensor? related to knock sensor then.. Why is it adjustable?

 

I've never seen an adjustable one before...



Got a pic of the offending beastie?

 

How do I load pics?

 

didnt i already explain that to you once?

 

Yea haha. I did it once but can't seem to do it again.

 

I think i got it

does that work? Top right is the sensor

 

very very close



you have to add the image tags



when you post it pops up a window with options like smiley faces, bold underline etc



click the one that looks like a picture of a tree and add the link to that



its 2 to the right of the smiley face
