Knock sensor, any other solution? standalone knock sensor log or visual?
Hello
Is anyone running something like a standalone knock sensor with a gauge to display knocks or pings? i am just wondering. I have a open wastegate and it gets really loud i am not able to hear anything besides the exhaust. i don't want to blow something up if you know what i mean. i read about some DIY gauges that you can make to display when the knock sensor is activated. would this work for mazda? anyone have one? looking forward for some input. -jasko |
Shouldnt it throw a cel if it picks up knock?

I use this with the stock '99 sensor. Works like a charm. Just tap it into the stock ECU harness and have fun. Come with an LED so you can "see" when knock occurs. You have to tune it to your sensitivity liking. When connecto to MS you can retard iginition based on knock.

As far as I know, only NB's had a knock sensor.

I've been using this for over a year now, great product:

http://www.vividracing.com/catalog/p...ducts_id/15475 looks pretty good but i am talking here a HOME BREW something cheap it don't have to look good just do its job. any other takers? |

For me, it's down to either that or the KnockSenseMS, though I like the fact that the sensativity scales to RPM on the TurboXS unit. On the downside however, the TurboXS unit does not appear to be tunable to the knock frequency of the engine, unlike the KnockSense. Decisions... |
hey guys sorry i havent been around i just got married & got back from my honey moon.... (p.s avo kit is now on also :)
the million $ question i would like to ask is why cant we get the knock sensor on the emu to work... & could it somehow be connected to one of these units to retard timing (like a standard ecu) ........ now that would be great :D |

The alternative: Find a standalone knock sensor that will be fed into the EMUs AFM input line, and used to drive the IGN2 map. Gonna try a KnockSenseMS to see how that goes. |
really usefull parts...

You can try to get a J&S and see if you can adapt the knock signal to the EMU.

dont mean to steal the thread, but i'm actually looking for one too. i've got an NA though, with EMB. any suggestions on that one?

I think that one has already been done, it's just too damn expensive. The KnockSenseMS is under $100, and I think that for those of us not using the AFM/MAF input on our EMUs (which should be everybody) that you can feed it into that input and drive an IGN map with it.

Any reason not to try it with the stock '99 knock sensor on a '99 motor that will soon live in my 92 with EMU and AFM removed.
That's basically what the KnockSenseMS is, along with a comparator to drive the outputs. *** whenever you mention removing the AFM you have to credit Joe Perez |
I was just giving you a little grief. I am really happy without my AFM and know how much work you put in to make it possible.
I am wondering how much I am going to have to adjust the Airflow Output Map to compensate for the different flow characteristics of the 99 head being force fed from a 1.2L whipple supercharger. And to keep this on topic, I guess I will just log the stock knock sensor output. |

What about the OP and his cheap standalone knock sensor that requires no other aftermarket parts (not everyone runs emanage) There isn't anything cheap that does not need to log or be plugged into a fancy computer or anything?

knocksense or knocklink
your ears work too. |
