I am pretty sure that I am fighting a case of phantom knock due to a bad case of lifter tick. Pretty much everything on my car is stock - and I was wondering if anyone could explain how to ground / bypass the knock sensor (for testing purposes). I have done a few searches, but haven't quite figured out how to do this. Someone said that they ran wire from the threads to the chassis....do you just wrap the wire around the threads? how do you attatch it? Any help would be great. :coy:


fyi - it feels like my ECU is pulling the timing when the lifters tick. This happens the most in 1st gear at low -med RPM's - but if I let off the gas and then floor it, then the car takes off. Same scenario in 2nd gear - the car bogs in 2nd gear with low to moderate RPMs. It also happens in 3rd gear. The problem is pretty intermittant (it does not happen all the time, but is seems like it happens a lot). Unfortunately, I don't have any logging tools, so I can't get a knock count. If I have a laptop, what is the easiest and cheapest way to log my data? I found a few posts with some info, but they were pretty old. I was looking at Tunerstein, which only seems to require the obd ii / serial adapter for the car to communicate to the laptop. Any other suggestions?:sosad:
 
If you check on ebay they sell loggers for OBD I, I just got mine for around 80 bucks and it should be here today actually. I belive they sell cables so you can log on your laptop too, but I would check into that.
