I'm running the smart 91 octane map from the web so I don't have 40's, I ended up changing all the zeros to -100. Seems to run fine now.

Thanks

 

I just caught up on this thread, and your wiring seems to be wrong...

http://www.grippybits.com\random\xed...artInstall.jpg <- 56k death, you have been warned.
The picture is my Smart install.

My wideband install =
Brown from wideband - purple on xede (the update wire)

Green, white, and blue on wideband - ecu ground (connected to the xede black)

red from wideband - cig lighter brown wire

pink from knock sensor - pink on smart buffer
yellow from smart buffer(SB) - pink on xede
red from SB - tapped into xede power
black from SB - tapped into xede ground

Shiv himself did my install of the smart buffer, I finished it off later with hooking up the LC1.

 

I have read your update and i'm a bit confused -- I understand Shiv did your install and he knows his stuff. However, on their website for the wideband / Knock Buffer install -- no where does it mention anything about the yellow wire on the knock buffer. What does that yellow wire do? Only reason I ask is -- I'm having some serious problems with SMART timing working. Could this mystery yellow wire be my problem? Here are the directions below off of their website -- so what should i do? Do I need to connect that yellow wire to the pink wire on the Xede and my problems are solved?



V. The grounds for the LC-1 wideband are Green, white, and blue. The ground for the knock buffer is black. Combine all of these grounds. Also include the black side of the LED supplied with the LC-1 kit in this group of wires.

VI. Strip off a small piece of insulation on the xede ground, which bolts to the ECU. This ground will be solid black.

VII. Connect the grounds from the wideband and knock buffer to the xede ground.

VIII. The power for knock buffer board will be red, this wire to the xede power. This was the wire stripped in step VIII of the firmware section.

IX. As for the Red power wire on the wideband harness, connect that to the wire that came from the cigarette lighter.

X. The only remaining wires should now be, black and yellow on the wideband, and pink on the knock buffer.

XI. Tap the pink wire to the pink knock wire on the xede harness. This wire will be in pin 4 of the black connector.

XII. The black wire on the wideband is the calibration wire, and the yellow wire is an un-used output wire. Connect one side of the momentary calibration push button to this black wire, as well as the red side of the LED. The wiring is complete. Please note that the other side of the calibration switch is disconnected to protect against an accidental calibration while driving.

 

if you look at the photo behind the link that is the way it was hooked up. I know that the smart buffer is just that, a buffer to queue up the knock readings to allow the Xede to read knock with 100% accuracy.

I suspect that the pink and yellow wires are inputs and outputs to the buffer, make sense to you? The pink wire is the input to the smart buffer, and the yellow is the output to the xede. That is the way it is wired into my harness.

Dustin@vishnu,

I cruised over the latest install steps and saw nothing that tells you how to hook up the smart buffer. Is that normally patched into the harness? I suspect this is the cause of these problems mentioned in this thread.

 

...the yellow wire location is insconspicuously stated in step II



<SPAN style="COLOR: black"><FONT face=Arial size=2>II. Before placing the orange locking piece back into the bottom of gray connector, place the yellow pin of the knock buffer into pin 9 on the gray connector.

 

WTF I can not post the text below in my post it gets scrambled up
Wideband and Knock Buffer Wiring

I. If you used the purple wire for updating, remove the Purple wire, and using the same process as before, move the purple wire back into the pin that it originally came from. (Pin 10 on the gray connector)

II. Before placing the orange locking piece back into the bottom of gray connector, place the yellow pin of the knock buffer into pin 9 on the gray connector.

 

Looks likes we have conflicting information. On Chris W's post, Shiv install, they have the yellow wire from the knok buffer connecting to the pink wire on the Xede. On Jorge's instructions, he says you put the yellow wire into pin 9. So which is it???

 

These are not my instructions these are posted on Vishnu website the knock buffer(KB) has both a yellow and a pink wire. The pink KB wire is spliced to the pink wire on the xede and the yellow KB wire goes into pin 9 on grey connector on xede

 

i had to read the instructions SEVERAL times, luckily i had the time to take my time, they aren't crystal clear. jorge has it right, pink on the buffer to the pink wire on xede harness and yellow wire into pin 9 of the grey connector

 

Jorge, I have followed those instructions & smart timing is still not working. In Chris W's pict, Shiv installed it differently. He has the yellow wire from the knock buffer connecting to the pink wire on the grey connector on the Xede. He also has the pink wire from the harness going to the pink wire on the knok buffer. That is where the confusion lies (see link below)

I did not have to update my Xede to version 3.2 since it came that way from Vishnu. I have cut the purple wire and have it connected to the brown wire on the wideband. My confusion is coming from the written directions, the SMART diagram, and now Chrisw's post (since Shiv did the install of the knock buffer)

Can anyone verify which installation directions are correct???? HELP!!!!

 

I have not confirmed this on my install, but I belive pin 9 on the grey xede connector is the yellow wire

 

Your picture you posted earlier shows the yellow wire from the Knock buffer going to the pink wire to the Xede. Can you confirm what your installation truely is?

 

Well guys I think I found out what my problem was -- just waiting on Vishnu to call me back to make sure my guess is correct.

 

confirmed, pin 9 on the grey connector has the yellow wire.

 

I see what you mean, some knock buffers were sent out without a deusch (sp)connector on the yellow wire and a pigtail with connector had to be used.

I hope you solved your problem.
