Thread: KR sensor,running lean and oil psi

Ok so the 97 gtp has pod gauges ne way it has what I believe is a kr sensor its cheap and it goes from green to yellow to red. Without taking it out what would that run off. The pcm or the knock sensor.

It has a narrow-band air/fuel. The car seems to run lean when it is first started up but after it warms up it seems to trim out and run about perfect. But after I put the boost to it it seems to run to the lean side for a min to two. Kinda funny.

I don't have the 200+ for a wide-band as ive just replaced the whole rack. I think the car was tuned at some point b/c it shifts out of second gear at like 5k rpm at wot. Would someone doing a ****ty tune on it have anything to do with all the stuff that seems messed up. Im pritty sure it would but is there anyway to tell if it has ben tuned w/o having to pay someone like 300 bucks to get into it or is there a way to reset the tune and see if that helps.

The KR gauge runs into the red sometimes and it scares the hell out of me that it is going to blow up. I have only filled it up once with 92 octane. I don't know if the KR gauge is correct of if its a pile of crap they put in there for looks.

The oil press says its running like 75psi at idle I'm guessing that's way too much and when i get on it it runs about 100psi. What is the correct oil press. How would I fix the massive oil psi. Would I have to drop the pan and check for a high vol oil pump or could it be too heavy weight oil making it run extreamly high like that.

All I know that it has had done to it is a dp catback and drilled and slotted rotors and k&n cone. My wife has the car atm and I don't have a tape measure to check the pulley size by measuring it. I got some pics I will post of pulley. There is no markings on the pulley itself.

the flashing lights gauge that moves form yellow to green to red is a AIR FUEL RATIO GAUGE, not a kr gauge, the flashing lights do nothing, it just reads the narrow band signal off the front o2 sensor wire and gives you pretty lights too look at and is completely inaccurate.


At start up the idle COLD psi should be around 70-75, and HOT idle( after its fully warmed up and roughly 5-10 miles of driving) should around 40 psi give or take a few.

If you start it up and its at 75 and then you go WOT right away I do not doubt that it would 100 psi, and it your the kind of person that does that your a ****ing retard, and you will blow your motor up. The Knock sensor's dont even turn on till 160* and befor that there is no way to hold back the car from killing itself at WOT.

as for the picture it looks like a stock pulley size to me.

no no going wot off start-up yeh no **** that's stupid lol. I mean after it is warmed up it still has high oil psi. My narowband air/fuel gose from red to yellow to green.

The KR GAUGE is from green to yellow to red and they are single led's not a band like the air/fuel and it says KNOCK on it. My air/fuel is a autometer phantom series so is my oil psi and the other one dont say it just says KNOCK.

If I flip the switch on the kr wherever the led lands it locks that in and dims the led's out. As to say here is how high the kr is. Forgot I got picks of it not sure if they are good picks or not. I figured it was a stock pulley just wanted to make sure someone didn't royally f the car up by being a moron. The top one is the gauge in question if you cant tell

This knock sensor...

bam nailed it cept it is white lol didn't know if it was ne good

I cant tell if each one of those lights is 1* of timing or not cant find anything on there website about how it works
