Hey Guys

Just wanted to make this video that many were askign about...

I have got 16 channels going full blast... Here is what's possible with an LM-1, and LC-1, LMA-2, and TWO LMA-3's (AuxBoxes). This video of my the playback of an earlier log (which I always put up on my NAV screen with my in-car PC going). It's really a tremendous, end-all setup that allows up to 32channels going at the same time, each recorded at 12 samples per second.

Here is the video (rt-click...save as..):
VIDEO

So far:

Now, this is a work in progress of sorts..didn't quite make it before the car went under the knife again. So, the following as you can tell are not working yet (BTW..all of these were fixed in the beta 2 version of the AuxBox, just haven't had the time at all to load it in yet... but the firmware is about to go final int he next couple of weeks):

1. RPM
2. Timing Advance (which is refering RPM..hence not workign by extension)
3. EGT/CHT (cyl head temp)

ATF1 IS workig, that's just how the sensor fluctuates while the car is running (as per the service manual). Accel pedal is off only because I haven't head the time to calibrate it 9takes about 2 minutes)...

The video may not be up for long if I hit my bandwidth limit soon.

Just wanted to share...this is truly an awesome setup...I also have two XD-1's that i use when i need. Overall, this is a modular setup, and you get only how much and what you need. They also have two more unique modules coming out, for multi channel thermocouple readings and non-sensor AuxBoxes...

Take care guys...let me know what you think.

 

Wow, very cool. Wish I could show that on my Nav screen.

 

GurgenPB,
Checked out the link you posted. That is a pretty slick set-up!! Pricey but seems like it's well worth. A system like that is perfect for tuning on the street and coupled with, maybe an HKS knock amp, you could come pretty close to that of a dyno tuned car. I'd be interested in hearing more about this..

 

Trust me, knock AMP (or any knock sensor) is by far not a very good and reliable indication of knock...and it is certainly rendered useless as soon as you affect the size and material of the combustion chamber, i.e. pistons, sleeves, overbore...etc.

The other reason that you will want to have Innovate! is their upcoming ion sensing setup...what's currently used on the SL65AMG, and ALL formula1 cars. google it, you'll know what I am talkign about. It will revolutionize the way every car is tuned, period.

 

very sweet setup gurgen...interesting how the a/f differs that much from bank to bank!
keep us posted, good luck on the current project

 

Beautiful setup! Keep up the great work!

 

Gurgen
So are you saying that going over bore and new pistons effects how the knock sensor works ? Meaning its it picking up more or less knock ...that is or isn't there ?

 

Hey booger I'm only making an assumption here but he could be talking about the increased noise due to piston slap. But, from what I understand about knock sensors is that they're usually tuned to pick up a certain frequency range. Something like 6200Hz for pinging... Supposed to alleviate false readings from other internal engine noises out of that frequency range..
It would seem to me that all the guys here with built motors would be experiencing severe timing retard if what Gurgen said is true.

 

I have lots of piston slap , even on a warm motor . [ block getting re-done soon ] and my timing seems to be pretty stable at 22 btdc at WOT . WHen the CAS wire wasnt wired quite right...the ECU was pulling tons of timing out...but its good now

 

That too..increased noise from piston slap CAN be interpreted as knock, as least certain kinds of slap. This is a fact. Here is why. When I had the J&S Safeguard (on my stock motor with TT), which is tuned to recongnize knock the same way as the stock ECU, as soon as i took my foot off the gas, the deceleration-induced piston slap was seen as knock according to my J&S display.

What I was talking about above, and you can find htis info by googling it, is that hte frequency of the sound produced by detonation is dependent on the factors mention (material, etc)...so it's not a set frequency just by virtue of being knock..it depends on many other factors. At least on my sleeved block, trying a multitude of timing maps never got the timing to be anywhere above 12-13 deg BTDC until I reached the end of te knock feedback region (5200rpm and above).

I may be wrong on thsi, but that's the evidence so far.

 

Gurgen:

I'll bet you left the pressure port on the back of the unit open.

Piston slap on decel is common, so the unit is programmed to ignore the knock sensor when the vacuum exceeds five inches.

 

Just watched that video for a second time since you posted it, its amazing, but i'm not going to lie...watching that gave me a headache

 

Hehe. Well the downside to having that much data is , well, the data. It's all in the organizaton, the left most column is all temps, etc.... I am adding another 6 channels soon, s organization is going to be more of a concern.

 

Oh yeas I know, I was just trying to illustrate a point.
