Please delete found answer must of had bad copy reinstalled and works

Innovate gear is as handy as it is quirky or buggy.  Seems like you always have to jiggle it just so before everything works great.

JD thats exactly what i was thinking. when it works its great but the headache before just gets rather annoying.

well since this is already open got some different questions. i was testing logworks and the SSI-4 on my blazer. i noticed some spikes in the rpm pickup?


as i was increasing rpm it would spike real fast. even at idle (800rpm) it would spike up to about 3-3500rpm? is this an indication of a bad coil possibly? letting it sit at idle it would look like an oscilloscope. i have it tapped at the tach signal below?



Moving forward im loggin maf volts and logworks dosnt have grams per second just grams. i am unfamiliar with maf tuning so does the first diagram look ok? I have it set 0v = 0G and 5v = 100g well at idle it says 42.1g on my log then adding rpm (no load) it drops  34.9g's at 4,190rpm. basicly do i have this set up correctly i am assuming i am.


here is the pinout i tapped into.



And last question i wanted to log knock i dont know if my knock sensor isnt calibrated right in logworks or just damaged. when logging it was at 5v's constant. I have tried volts and frequency hz nothing correctly logging it could be damaged but car isnt throwing a cell for it either.

you can see in the pic above i had it on V and you can also see the HZ table equation.
I can log this and post up shots if needed. also its real easy wire to figure out to tap into.





Hope i didnt discourage people from reading this novel of a post.

Look at the spike in the tach signal and the corresponding dip in MAF signal.  Makes me think it is a missfire.

As for the KS, if should read volts where you have it tapped in.

Maybe the ECU provides a reference voltage out.  I dunno as I haven't honestly messed with a GM knock sstem in quite a while.

I've only used LogWorks for generic OBD2 stream stuff.  I'm zero help.  Knowing Klaus, he's produces nine well detailed user manuals on the subject and the Innovate forum would be a top notch place to ask advice.  If you get a thread going there, do provide us a link?

I see no dip in MAF when the RPM pickup gets flaky.  I don't see where you're getting that.  I think I'd rather try an inductive clamp or sythesized digital tach feed as the place you've chosen to pick up from is unfiltered and looks like it's a noisy signal.

AFAIK, all KS are piezoelectric aka produce their own voltage.  Treating them as an amplitude signal aka volume meter is NOT how to deal with them, but if you do it will usually indicate actual knock - that you could have determined readily by one of several other methods anyway.  Still, fucking with it might reveal something interesting that I, who belligerently do not pay attention to raw KS outputs, am unaware of.  If you run up on something interesting please share.

It broke up elsewhere without quirks, and stayed low while rpms increased.  Without more detailed logs (TPS, etc) or experiencing the vehicle, that could be normal operation.  Hell, look at it - MAF "dips" inversely proportional to the increase in RPMs with no hiccoughs where the tach feed is obviously breaking up.  Insufficient information to make any statement, sorry.

[snm95ls]

lol.

I guess that is what I get for trying to make some sort of correlation with the info provided.

 

[Joseph Davis]

50% chance you're right and I'm wrong.  LOL

There wasnt any dip in maf it was functioning fine (just dont know how to read grams correctly, buddy who owns the dyno i use uses grams per second he is currently on his way back from Wisconsin but i will also be asking him.) I can always log tps JD and do some more logs. My blazer is just a daily and im testing to make sure i have everything working correctly in logworks and have all sensors hooked up accordingly.

JD would digikey (or equivalent)  have a small inductive clamp i could buy and use with this i think that would work 10x better as well.

I will update my innovate forum post and link it over here for all to see. I posted here mainly because this forum gets faster results then others. i will also log TPS tomorrow instead of knock and post some more pics.

here is the full shot of the log as you can see idle (900rpm) maf is fine at 42g and when rpm spikes no effect. but you can also see it spikes to 3000rpms every so often at idle. this is where i say it looks like an oscilloscope.



Thank you JD and snm95ls for all info and theory's in this thread! if i do find other information on other forums i am sure i will inform you guys first.

[snm95ls]

What the hell was going on in the part that I circled then.  Did you blip the throttle or something?

I am so  now.

haha.

I am sure tapping into the tach signal at that point is pretty damn noisy considering it is directly connected to the primary side of the ignition coil.  any variation on the secondary side will be reflected on the primary side, and with how Logworks interprets the signal, it wouldn't surprise me in the least to see errors like that.

What GM vehicle is this on?  The only v6 with a distributor, and running a speed density setup that comes to mind is the Vortech 4.3 V6.

Lol thats what i was doing in the part you circled. I wrote that was under the picture that you actually circled. yes its a v6 vortec 4x4 blazer with spider vain injection (just test car). im hoping if i buy a inductive clamp that might filter out alot of noise. would like to see working knock though, ill see if anyone on innovate boards know anything about setting up that sensor. if not fuck it if the tq graph doent move on the dyno stop adding timing lol.

[snm95ls]

I need to learn how to read apparently.

 ;D

You will still have to deal with knock retard unless you can disable it.

[Joseph Davis]

I have an inductive clamp that was part of an old Road Dyno setup I could never get to work right.  It just ended in a 2.5 or 3.5mm audio jack, may or may not need circuitry to process it's output.  I think I still have the cable - I might have the whole Road Dyno affair somewhere - I'd be happy to drop it in the mail to you if you PM your address.

Thank you sir PM

I could disable it with HP tuners but im just making sure this is working correctly on my truck before i try this BMW E36 again.

[snm95ls]

Try tapping into the purple wire with a white trace coming from the distributor for cleaner tach signal.

It's worth a shot until you get an inductive pickup to mess around with.

I will also try the other rpm pickup tomorrow. and have more logs up aswell as tps reading.

[FreshDA9]

Ok i did some logs but i think i hooked up to the wrong tps wire.

here is log one.


and here is another log


Doesnt look like the tps signal is changing when the spike happens. but i might need to hook it up to the 5v wire and not the tps signal. i will try this tomorrow.

I hooked into the red wire and i am thinking i should have hooked into the green. i will try the green and see.

I will try the purple wire from the dizzy when i get more time. its kind of buried in the back (thanks chevy for putting so much shit in a small place).

[snm95ls]

You tapped into the correct TPS wire as you want to see what the ECU is reading for TPS signal.

Your MAF signal looks inverted for some reason.  Where did you tap into the MAF signal at?

EDIT:  BTW, your MAF units on Logworks is only in grams because it is being plotted against time, thus grams/second.
