ESE's works engine tuner

[Sketchy_Racer]

Hey guys,

I noticed earlier you have knock sensors hooked up to you bikes, I was wondering if they are also suitable for 4T engines and where I may source one?

Cheers,

Its a bit of a pick and mix so I highlighted the dollar amounts so you can see where the prices come from.


$63.50 NZD for a counter from RS components

http://www.ebay.com/itm/Knock-gauge-...b8220d&vxp=mtr

Knock Gauge $49.99 plus option 1 switch to ground for the IgniTec ignition retard add $20 plus option 3 pulsed 0v to 5V for the counter so add another $20

$90 USD for the Knock Gauge part off Ebay.

Less than $200 NZD should cover it.

Good luck with the Deto sensing TZ. I like the little warning instrument!
My sensor has a PN 0-261-231-001, what's yours?
According to this http://www.phormula.co.uk/KnockCalculator.aspx , deto freq for 56mm bore should be 10.2kHz.
According to Bosch datasheets for PN -047 & -120, sensors are able to catch frequencies from 1 to 20 kHz.
I assume all Bosch sensors can sense knock within this range (?)

edit: As for the pick-up voltage, I think it won't be more than +-10V. I had a voltage test yesterday with a data acquisition device in real time! I spinned the crank by hand and recorder the voltage waveform from the pick-up in the PC. As RPM increase, amplitude (and freq of course) of the pulses increase - by hand-spinning it didn't exceed 3~3.5 VAC. Sure it was a lot of fun to watch!

Its funny you say that. I have presactly the same Subi deto doofer & knockgauge. I connected it yesterday & went to the dyno. Rang up like a tree. I ended up ignoring it & feeding in smaller jets & advanced timing increased the power so I can't believe it was setup right.

My sensor is on the side of the cylinder. I wonder it it is just getting too much vibration? Not that it vibrates that bad. . . I turned the dial to try calibrate it & didn't get much change. maybe it is in a sensitive plane to operate the piezo.

I have just been putting on my knock gauge on the bucket and when I run her in the drive with the sensitivity set half way, reving the bucket up the gauge went off like a christmas tree and I am wondering what others have there gauges set to?
The gauge is from http://www.knockgauge.eu and the sensor is off a subaru car. It's mounted on a 100cc LC two stroke on a head stud straight onto the head with nothing inbetween if that is any help.

Ok mine turned up today.

Attachment 263027

And a couple of two wire sensors I picked up cheap from the local garage.

Forget the homemade bullshit, get one of these with the extra wire to ground.
When it sees deto it can ground an Ignitech input and retard the timing automatically.
You get flashing lights and engine protection all in one shot, and cheap as chips - made in Czech so it likes being connected to an Ignitech - same lingo..
Works perfectly - when you get it trimmed correctly it will tell you where to manually pull out timing, then it just operates as a failsafe.

[crazy man]

Our sidecar was 10kg heavier than the Griffiths chair, swingers about the same, riders we made our 10kg back with interest

so your saying l'm a fatty

[Henk]

so your saying l'm a fatty

In a word, yes. Don't you weigh more than your rig?

[Bert]

In a word, yes. Don't you weigh more than your rig?

That might be tooo close call
it could be the next poll (though it could be a close call between a few members of team GPR)

Bert, I'll give you a clue, there is 2 kg in it, you decide which way.

I weigh as much as the Beast, do I get a chocolate fish?? ....

[TZ350]

... it could be the next poll ...

If you are going to run a new poll, I suggest you don't do it on your own thread as polls are real hard to get rid off, I needed the Mod's help to clean up the ESE thread after the Sidecar/Beast poll.

Next time a poll sounds like a good idea I am going to start a new thread just for it and when its run its course, I will let it float off into the distance and post the results here.

And a couple of two wire sensors I picked up cheap from the local garage.

Knock Gauge.... $49.99 USD plus $20 for option 1 "As switch to ground;"

I found some steel head bolts and faced one off, then drilled and tapped it. And made a standoff that was carefully faced off as the knock sensor likes to be securely mounted on a very flat surface. The black goop (silicon glue) on the blue wire is there as a strain relief and hopefully it will stop the vibration breaking the wire where it is attached to the copper head fin.

703TR002N-512D RS part number 183-5952 $63.50 ... 5-12V and less than 10mA so easily self powered and at 500Hz fast enough to count all deto events as seen by the Knock Gauge or similar, as 200Hz in a 2-Stroke equals 12,000 rpm.

Attachment 269008

Knock Gauge and Det Counter ..... $49.99 USD plus $20 plus $20 for option 1 "As switch to ground;" and option 3 "As 0v + 5v output;" frequency output for the Det counter to count.

Attachment 270747

I have just received another Knock Gauge, this one has two extra outputs. http://www.knockgauge.eu/content/blogcategory/22/41/

YouTube links showing the Knock Gauge in action.

The two green lights, the orange warning light then you see the red det light. http://youtu.be/aZkZR-JBr_E and http://youtu.be/vFoZyw_sHmA

Like last time, one that goes to ground for signaling the IgniTec to retard and a new one that pulses from 0V to +5V each time the Knock Gauge sees a detonation event.

The Curtis event counter can then count the detonations. Now I have the makings of a det sensor, ignition retarder and det counter.

I have yet to try the Knock Gauge come Det Counter, but it looks promising.

Seen these today.

antaper Sticks & sanding Belts
This Auction is for one Sandtaper stick with one belt and an additional 5 replacement sanding belts Total $ 23
On completion of Auction choose which grit you want from
120 240 320 400 and 600
What many are doing is just buying one stick and a range of 5x5 papers
But they end up coming back for the set as they work so well
Fast, easy, economical way to reach detailed, hard-to-reach areas. Plastic stick, tapered at the end, holds a replaceable 1/4" wide sanding belt. The aluminum oxide belt is held in place by a patented spring- loaded mechanism that allows the belt to be rotated 360. Rotating the belt exposes a new sanding surface and allows the entire belt to be used.
I find these a valuable asset enabling me to get into those hard to sand areas on my carving or texture on my woodturning
Replacement Belts pack of 5 in either 120 240 320 400 or 600 grits $14
Additional Santaper sticks $8 any color

Thanks for the info guys, sorry I was too lazy to search for it, busy making superchargers an all

Once I get the supercharger performing I will invest in one of these as I'm sure you can imagine boost will encourage det.

Actually, a question for who may be in the know - Fuel, would AV gas be better fuel to run in an forced induction motor? Detonation is going to be the killer of my little chinese motor so I would have thought that Av gas will help this?

Cheers,

Sketchy

[F5 Dave]

I must imagine Av would be the safest when lots of boost is required. You can have a guernsey at my knock gauge. I have to get it reattached when the bike is watercooled, perhaps you can try it out till then.

Totally Legal Good Part.



TeeZee no need to make one, here is a rear pulley sheave with curved slots like you were talking about.



NCY describes some of their parts as "Race".

But there are none of the naughty race words on the manufacturers web page for this sheave, or the sheave itself that would make it an illegal race part.

In spite of what the re sellers might love to call it, it looks like it was manufactured by NCY to be just a better part for a gy6 street bike/scooter.

Now if you could find a sheave with axial slots, that would be someting....

Hey TZ,

What do you reckon the beast is capable of in a straight line? Maybe F5 Dave would stand a chance on his 50.
