I hope I can get some help with the hook up of the Inovate WD to my Autoprom.

I have read all that I could find on the matter and I believe I am doing it right but all I get Is Zero for a #.

Here is what I have done

-comfigured my lc1 to read 1-2 volts on output #2 - this has been verfied with a volt meter

-hooked output #2 of the Lc1 to F14 on my ecm

-made #37 Min iac read - 0035 hex 0x035 calculated

- set bit - wb opt #1 Sensor Select Bit 5 innov

- left the rest of the option 1 and all the option 2 unset

- made aldl def for #37 in tuner pro - 8 bit - multiply + offset (factor 10 offset 0)

I must be missing something, Please help

 

I had trouble getting that to work as well - so I set the LC1 to linear output 1-5v and used the "Plex Linear" selection and it works fine.

 

I'll have to give that a try too.
You said your WB was in the same place and it reads. Mine just jumps up/down full scale.

 

Yep, mine reads fine. Had to put it on the slowest reporting period though so I could even read it

 

Tried it on the Plex with 1-5v, and it did not work. Just have zeros.

Will look at it again another day.

 

And you did set the LC1 output to 1-5v, right? Are you sure you're using the right output wire from the LC1 to match up with the output programming you did (brown vs. yellow wires)? Everything else sounds correct. I'm using the A3 input instead of F14, but that shouldn't make any difference. I tested both ECM inputs for Z69 when he developed the S_AUJP V3 patch and they worked the same. I couldn't get the 1-2v Innovate (or was it 0-1v?) choice to work correctly is why I'm using the 1-5v Plex setting (plus better resolution).

I'd take a step back, relax, verify you're using a WB patched BIN, and then slowly go thru the entire installation, wiring, calibrating, etc. of the LC-1 as well as the ECM connection. Any chance the ECM connection isn't making a good connection? What did you use to install that new contact on the harness side of the connector?

 

Yes I will have to go at it again. It will get fixed with time and effort.

My conection is good as I took a pin and the wire from a old wiring harness and place it into my good harness.

Somthing that i did not do with the plex idea was disconect my autometer led gauge. I just fed it 5volts and it survived. I would not think that it would have a voltage drop being hooked in paralel with the ecm but it is possible I a dropping the voltage on the gauge. I will try disconecting it and trying again.

I really don't understand what is being done on #37 Min IAC.
If I look at item summary I have 0035 in hex and 0x035 in calulated.
If I go to #37 Edit xdf item Info it says original value $002d. The adress is i 915 in hex. Is this correct? I have no idea about this stuff it is over my helment.
The data stream defintion I may have to change my math a bit for the Plex scaling but until i see some #s comming out of #37 I am not able to use my wide band very effectively in terms of logging with my other inputs.
This patch will be great when we get it working.

 

Your looking in the right spot, the value at 915 should be $0035 to show the WB output at position/word 37 of the datastream.
The original value at 915 was $002d to show the IAC parameter as word 37.

If 915 is $0035 you would be reading the right item.

 

IF I right click on #37 in the constant scalers in tunerpro - then go Edit xdf item it gives me a tab for aldl asociation then I can select my wide band o2.
Is this nesecary, I have not tried it after doing this.

 

I want to jump in here, as I have the same problem. WB reads fine with the NB sim plugged into the O2 pin on the ECM (I'm running a '727). Ground reference is wired to the O2 ground from the ECM. This functions correctly, as it shows up fine in the datastream.

Now, I do have my .bin file patched using the WB patch for 8D that is out there.

I created a new XDF item referencing address 915, double-byte constant, and it reads $002D. According the the post above, it should be $0035. Why did the patch not take care of this?

To verify the patch was installing correctly, I reinstalled the patch again after I had set up the word1 and word2 values (for WB type, and pin/raw data respectively), and when I reopened the repatched .bin file, the values were reset to 0 across the two bytes. So assume the patch did work.

So, the final answer is, change address 915 to the value $0035 to read in the WB data to the ALDL stream byte 37, as opposed to reading in the IAC min value to ALDL stream byte 37. Correct?

 

It helps if you list what bcc your working with.....

If you need to change 915, then the patch didn't apply correctly. You can only use the patch on bins with the same exact BCC.
You could also use one of the bin's that's already patched.....
I checked several of my files and all of them have the change to 915 in them.
So far, every problem has been with the car or the driver. Not the bin.....
Doesn't mean one won't pop up. Just that it hasn't yet.
AFA the 1-2v problem, I don't recall if I checked that function specifically.
But the original author of the code did. So I suspect an LC-1 problem.
I did verify several of the conversion options though with a fluke sampling the test voltage. But it's been about a year since I did that....

And I thought it was 0-5v.....
Do some digging in the original thread or on the SyTy site.
That is where most of the conversion work was done.
I have to get back to unpacking...

 

The SyTY site does have alot of info and will read threw it.

A quick question on the Datastream Definition stuff. It was said to make the Wide Band definition similiar to Fuel Pump volts (35).

Word 35 is 911 and 912
Word 37 is 915 and 916.

Both are 16 bit. Why does my Item Size say 8 bit In my ALDL Definition Editor for Fuel Pump Volts? It works but does the wide band (37) need the whole 16 bits?

 

You're right, Scott, the LC-1 and LM-1 both use 0-5v, with 0 volts = 7.35 AFR and 5 volts = 22.39 AFR

Please write the 1-5v comment off as a "Senior Moment"...

 

Yes,
The patch for AUJP is at that location, I haven't confirmed the others personally but I'm pretty sure they are in the right places.
To clear up a little confusion using the AUJP as the example,
The "Address" location 915 is $00, 916 is $35 to output the WB value.
The "Stock" IAC min will be 915= $00, 916 = $2D.
The address is a double-byte. The item "AT" that address ($002D or $0035) to be displayed is only a single byte (8 bit) value.

To verify you are looking at the correct location in any of the patched bins, check the addresses before and after the suspected 915-916 location.
Before "should be" = $0043 Diagnostic Mode word 4
---> $00 $35 New WB
After "should be" = $01BD Oil Temp (Linearized Value)
That is the same ALDL definition for all the $8D bins.

When in doubt, use the "Raw" output to see if you are getting data.

I've always heard to go with 1-2 V range from the LC-1, need to get a real confirmation on that. Others have had it working that way (I think)
I'm still fighting with mine BTW.

Ed: According to the AFR master voltages spreadsheet that I believe was used to make the functions, It indicates the Innovate Linear is a 1V-2V range to show 10 to 20:1 AFR.

 

If I check the raw in option 2 does this mean I have to use pin a3?
Raw has a address that is asociated with 2001.

 

... Different than I thought although it should be 1-2 volt input range.
----------
No, that is another bit (bit 7 of the second option word)
RAW is bit 0.

 

Went at it again, changed to pin a3, checked the conector tightness to the ecm pin, tried another ecm, disconected my autometer led gauge from output 2, changed the output voltage to 0-5v, then emulated changing bits and changing aldl definition math hoping to get a combination that worked

NOTHING but ZEROS

Looking for sugestions

 

Did you catch this?

 

Yes I don't understand "excact bcc" but I have been just changing 915 to 035 in my modified bin.

Downloaded aujpwb off the moates site I will uncheck the vats and try it.
