There is no "range" control. It is a piezo element in the sensor. It requires a specific knock sensor bolt tightened to a specific torque, 18 ft lbs I think.
I questioned this thread when it started. Then I understood what you meant.
Years ago I read something published, but I do not recall what it was. I believe the steps were 3 degrees until it stopped knocking. I'm pretty certain there would be a max retard and I suspect it would not be more than 10 degrees. No proof of that.
yeah about 10 degrees seems like a reasonable amount. I was just thinking, if an engine had false knock how far it would pull it back. the bearings in my alternator are starting to grumble and the ks is bolted very close to the alt mount. of course the ks is set to pick up only a certain frequency of vibrations. was also wondering if the digifant used a sequential retard set up, or does it just pull timing on all 4 pots at the same time
I'm no electrical designer and I understand every year software/hardware get better.
That said, I believe the engineers found the right type of noise that the sensor was picking up and used that for retard. I would think that it would know what is knock and what is not. I do know that TT Tuning does make an aluminum bushing that will dampen that signal and therefore reduce the sensitivity. I have one on my wife's 2H Cabriolet but it came with the chip. I do not know if it helps or not. With a dual 1 7/8 downpipe and 2.25" exhaust and a chip, you need everything you can to get an automatic transmission Cabriolet to move.
yeah I was seeing that spacer that tt make. my brother is going to lathe me up one. but he's going to make it 15mm thick. it might help, it might not. but it's free anyway the tt one looks about 35mm thick. could you confirm?
I won't be changing the chip and I still have to set the timing by strobe (been tweaking it with a vacuum gauge to find the sweet spot) will be interesting to see how close I got it
not going to bother with the spacer now. have the timing set so there's zero audible knock. really don't want to risk melting an audi 3a piston as replacements seem non existant
does anyone know what the coating is on the 3A pistons? it covers the crown and goes down to between the 2 compression rings.
