GM knock sensor thread Options

is that an ATS TB inlet? looks nice. i ordered one last week!

Yup, I ordered that and the GM Knock Sensor Conversion for Doc to install. Along with the healthy dose of goodies that he's putting in the car.......should be really niiiiiiice.

i woudlnt recomend using the GM knock sensor. it dosnt work correctly for our cars and ats should stop selling it imho. keep the stock sensor.

thanks for clearing it up jay, im going to have to say that i would definitly go OEM with a sensor like a knock sensor, but at the same time fastbird and tweak are big boys and if they choose to go that route even after reading the warnings then that is between them

I agree. But, Doc's attacks on Art were out of line, IMO. Art does more for this community in providing information and troubleshooting advice than ANYBODY! Plus I like his hair.

I'm going to have to see this hair I think

Back to the subject at hand, jgreening, you're still going back to the issue of using the GM knock sensor to "fix" a knocking engine. As I agreed, that's not the right reason to use this and would be a bad idea. The problem has to be fixed, not the symptom! But from the research I've seen and my own experience, there's no problem using a GM knock sensor as a less expensive replacement.

A good thing to think of is that if you purchase an MSD knock monitor, it comes with a GM sensor. Since this is a device that a tuner would use on a dyno to watch for detonation, and it's accurate enough for that, then wouldn't it be accurate enough for the ECU?

If it can be used to "fix" a knock problem it can let that same problem exist where a stock knock sensor would alert the ECU. That's not something I want to happen. I'll stick with a sensor that is designed for the frequency that our blocks resonate at.

MSD knock monitor is just another tool. Just because it can detect knock doesn't mean it was meant for our ECU... This has already been covered in the MR2OC post that Jay linked to.

Fastbird and Doc:

Your logic escapes me here. Please explain why this statement from Justin does not concern you:

Thanks.

Hey now, thats not true. I tightened a battery tie down once.

It can't be used to fix a knock problem. It never was intended to either.

QUIT PLAYING WORD GAMES! You know the word "fix" was in quotation marks. Justin wasn't saying that the GM sensor could fix a knock problem. You know that. The question is: Why aren't you concerned (based on the information that we have all now read) that the GM knock sensor which is designed for a larger bore cylinder will not pick up some knock and possibly result in engine failure in a 3sgte?
