LX9 reluctor demystified

[Jonpro03]

I spent a good part of the day researching the LX9 reluctor and it's events. It is in fact the same reluctor as the LS1 (it has the same pattern).

The question stuck in my mind is whether or not it has the same phasing (is TDC #1 compression stroke).

From this point on, I will assume that it is.

I started by plotting out the entire reluctor in a word processor.

You can see that I found 72 pulses. 72/3 is 24 events. Which means that each event is three pulses. So each cylinder gets 8 events or 24 pulses. For example, the first event for cylinder 1 is low low high or Y. The next event is low high high or X.
I used the following to determine phasing with the CMP sensor.

And this is the result:

Just the red markings. Ideally, the picture would be of the other side of the reluctor.

Updated to explain the pulses and events better and to clarify why it is a 24x sensor. If anybody has a reluctor laying around, would you do me the favor of taking a picture of the other side of the reluctor?

I'll scan in the other side tonight.

[Jonpro03]

I appreciate it. Do you think this would make a good article?

[bszopi]

I think it has potential. I'd like to see the full size version of the scope, as its hard to read.

[Jonpro03]

There's a link underneath the image to get the fullsize picture.

Totalling missed that one... Saw the others.

[Jonpro03]

Haha, I just realized I messed up the decoding. I'll fix it and edit it.

EDIT: fixed!

Whats interesting is that the LS1 reluctor is split into 4. So it decodes to

YXXXXX YXXXYY XXYYYX YXYYYY

That's pretty cool. On a side note, you run a lot of stuff in the background, lol.

[Jonpro03]

Oh, haha. That's not me, I don't use windows (much). I stole that from LS1tech forums.

[pocket-rocket]

Lol. I thought it was yours. Heck, I run only what I have to in the background, gives me more available power when I need it. I go as far as to disable stuff like Adobe update, iPod junk, ect in msconfig

[Jonpro03]

Whatever you do, don't disable Java Update service. I did that and about 3 weeks later I was so badly infected that it COMPLETELY wiped out my windows7.

[pocket-rocket]

Really? I do you recall what it was that did it in? I'm running 7 pro (hooked up from a friend in IT school with a legit copy ) and I run ESET NOD32 for antivirus. I even subscribed for both my pc and my wifes after doing uninstalls and reinstalls monthly for some time once our tax money came. ESET treated me well, so I felt obligated.

[Jonpro03]

I can't remember the name of the virus. But I know it was a java exploit. Nope, here it is... Java/CVE-2010. That's what i got. It tore my laptop up. Within 4 hours Windows7 wouldn't run for more than 2 minutes. Then safe-mode quit working. Now I run Ubuntu.

[Jonpro03]

I got a reading from the crank sensor (finally). Still not picking up the cam signal, so I can't determine phasing for sure. Hopefully I can get that sorted out tomorrow.
