I just downloaded TunerproRT (v5).
I'm connected via my serial port thru a DIY max232 and it's working great!

The only other logging s/w I have used is ECM852.
With the ECM852, I got the WB data (displayed as Air Fuel Ratio) in the data stream after I connected the WB vout to ECM pin D8 and used a modified ARAP bin.

I took a shot at modifying the ADX file as follows:
Using the ADX editor, I selected Channel1 under "Values". On the general tab; I changed the title of Channel1 to WB02, selected "Actual Air Fuel ratio" for my data type, set Range Low to 0.00 and Range High to 5.00.
On the conversion tab; I selected "send converted data to lookup table", set lookup table to "New Lookup Table".
For the new lookup table, I set the first input to 0 with an output of 7.35 and set the second input to 5 with an output of 22.39..


While researching this, I found a post that mentioned:

Use the (7.35-22.39 AFR = 0-5 V) LC-1 setting
Use calculation in ADS = mult by 0.05898039 +7.35 offset

The first line I assumed was to setup the "New Lookup Table"
I'm not sure where the second line belongs . Under "equation" maybe??

Am I on the right path here or completely lost?

 

After a bit more tinkering with the ADX file, looks like maybe I need the correct packet offset.
I think I'm looking for the packet offset for TPS2, A/D channel 0, but then again, I don't really know what I'm doing.

 

Without an AutoProm your going to have to find a 0 to 5 volt AD input into your ECM and use that address.

Channel 1 in your ADX sounds like it is one of three channels available for the AutoProm.

Yes the second line (conversion) goes in Conversion Tab of ADX value.

If you have the WB wired to Pin D8 then that is the value in the ADX you want to convert from whatever it was to the now Wide Band.

 

I am attempting the same thing but have not yet selected a WB setup. Dataloging with out Autoprom. However, I am using a USB port and Moate's ALDU converter. Any tips on how to set this up on 165/6E MAF system will be greatly appreciated. You may keep up with the thread I started as well. Or maybe we can combine the two since it's basicially the same issue.

 

I'm using a custom bin (based on the ARAP bin) that if I remember correctly, was modified by Moates back in 2005 for use with his ECM852 datalogging s/w. That bin includes W/B data in the data stream. It uses an prev unused A/D channel (channel 0) 0-5v input called TPS2.

So if I understand this correctly, the data is already in the data stream and I just need to input the correct packet offset to channel 1 to pluck it out.

Does this sound right?

 

That sounds about right.

You need to figure out where in the datastream the WBO2 voltage is being sent, then use that info to modify the ADX, and/or the existing value in the ADX.

 

I went thru all the "values" and "bitmasks" (of my known-to-be-good wb02 bin) making a list of all the packet offsets used.
I then tried most of the unused ones. Started at 0X00 and went up to 0x50, then tried
0A-0F, 1A-1F, 2A-2F, 3A-3F and 4A-4F. With each offset I cycled the 2.5 volts going to pin D8. My "Dash" WB02 reading never changed with the power cycling. I know the ECM is getting the 2.5 volts cause the ECM drags the 2.5v down to 2.45v. If there was no contact with the ecm, the voltage would be at 2.50v. Plus, I get a WB02 reading using the ECM852 s/w on my old laptop.
The only conclusion I can make is the packet offset I need is some odd-ball value I'll probably never find using this technique.
So much for trying the back door...

Do I need to disassemble my bin to find the correct packet offset? If so, what program do I need to accomplish that? Is there a tutorial somewhere geared towards disassembling a bin used on 165 ecms?

 

You might try the easy way and ask Moates? Those guys bend over backwards to help us you know?

Now if this was a hack to an origanal bin to change something into data stream the first thing to go would be Prom ID. Just looked at ARAP in TunerPro $6E and Prom ID was 1023, in hex it is the first 2 numbers. Check yours and see what Prom ID number is, if not 1023 then it has been changed!

Prom ID is 16 bit and in the ADX it's 0x00, I'm not sure what the other half is? 0x01?

 

You don't need to do anything with the bin, you're barking up the wrong tree.

You need to be looking at the datalogging side of it. I don't know what you used before, but if you can find the parameter that had the WBO2 data, look at where in the datastream it was and use that information in the Tuner Pro ADX.

With this being a custom set-up, unique to your car (only), you will need to use your previous files to figure out what you need to do with the new files programs.

The WBO2 input would likely be sent to an already used item in the data stream, just changing it's function. Usually less used items, such as PROM ID, or Start Up Coolant temp, or something along those lines would be changed to send the wanted data through the datastream. Some people use EGR input to have the WBO2 data in the datastream.

You might be able to open a dash board or the data list and while toggling the WBO2 voltage see which value is changing, then modify that value to display the WBO2 data as AFR.

 

I emailed Moates early today, but no response yet.

My prom ID is 1023.

I opened the bin in notepad and saw at the end it is copyrighted by Mike Davis. Is he still around??

 

The only logging s/w I've used before is Moates ECM852. It's a DOS based program. No way that I know of to poke around inside.

I started using the modified bin when I started using the ECM852. The bin was sent out with a text file that reads as follows:


Vout from DIY-EFI WB kit should be connected
to Pin D8 (TPS2, A/D channel 0) on the
1227165 ECM.

The WB AFR is displayed in the "Commanded AFR"
field of the ALDL stream, so it should be
able to be read by AND scan tool/package. The
Voltage-to-AFR lookup table was calibrated to
the published table to within +/- 0.5%.

Last Updated 03-Feb-05


I can't find a "Commanded AFR" or "TPS2" option anywhere in TunerproRt.

I tried watching the data list while toggling the WB02 vout power to ecm pin D8, nothing changed.

 

Did you read the other thread that had this link?

https://www.thirdgen.org/forums/diy-...band-data.html

 

Yes, I downloaded the zip file yesterday.
I had prev downloaded that zip file, viewed the ads/adx file, and noticed it was the same config I had already tried. Now I'm thinking if I used the bin that was included, it might work.
It will probably be next week before I get a chance to try it..

I've been told the bin file isn't the issue, but isn't the bin file responsible for where the WB02 data is located within the datastream??

 

Yup! If the hack isn't in the bin then the data isn't in the stream...

 

If you used this, the offset should be 53 in the datastream to view the D8 pin value.

 

That's good to know.. I stopped trying at offset 50 with my original bin.. Makes me wonder if I had kept going would I have found it..

I've made contact with author of the hac'ed bin I'm using. Hopefully he'll be able to provide the offset info I'm looking for.

 

If you are using my APYPWB or ARAPWB, then you need to modify the packet offset to 0x35 as JP mentioned.

 

Just for a little clairfication, I understand the "WB" adx has to be used/created to view the WB data when datalogging but why is it necessary to change the bin?

 

The way the BIN is set-up will control what information is sent through the ALDL diagnostic connector, this is especially true when you're adding a previously unused input to the datastream.

 

Got it to work using the bin here:
https://www.thirdgen.org/forums/di...band-data.html (APYPWB ARAPWB Wideband data logging are here)

Thx for all the help guys!!

 

Ok there may be an all too obvious answerr to this question. How do I connect to D8? I am right at this point, WB installed, WB bin, WB ADX with corrections made. I go to D8 which is "unused" and of course there is no connection. I suppose I get an appropriate female pin that will fit into the connector and attach it to my signal wire from the WB, right? Don't know where to find the wire end. Are there any "unused" connectors I can rob or just get something close. I presume as long as it fits into the "plug" and makes contact with the pin in the ecu I got it made. Like I said this may be too obvious but any tips here will be appreciated.

 

You can get a connector from a local wreckers and use a pin from it.

If you can't get to an auto wreckers, you can also go to a local Car Audio specialty shop and buy a Metra 71-1858 Harness. This is the car side, not the adapter side (70-1858), you can use a pin from the 71-1858 (or equivalent) in the ECM connectors for new or repair connections.

 

The terminals/wires from the EGR & AIR are usually available

RBob.

 

LOL!!

 

Ok tuners I need help. I have done everything within my abilities to get the wb data in the log stream with no success. Here is what I've done to date.

Downloaded the arapwb/apypwb/ads from the zip file linked in this thread.
Converted the ads to adx and made the 53 offset change.
Within the xdf made the explicit link to the converted adx.
Made connnection at d8.
Verified vout from wbo2 gauge is present at pin at d8 location.

When connected to aldl all data is present and appear correct except the wide band data. It displays 7.41 and doesn't move. It does toggle a bit 7.41/7.64 but doesn't seem to be related to afr~ just a wiggle.

I am at a loss. The only thing I haven't tried is to use the arap file. There is something I am missing and would greatly appreciate some imput here. WB data is great but if I can't get it into my log stream it is hard to use. Any ideas???

Update: Tried arapwb bin. no differance.

 

OK thanks to zz28zz I got it working. Strange, the fix was to leave the offset at 0x34 instead of the suggested 0x35??? Oh well whatever works huh? Still have a tiny issue that is a slight discrepancy between the MXT-L gauge and the value shown in the datalog. Looks like about +0.2 on the datalog vs the gauge. Gauge shows lower. Probably a fix in the math but I don't think it's going to be a huge deal Just thought everyone should know. Thanks again to all.

 

0x35 is for shift light? The ADS/ADX comes with 0x34 for wideband.

The differnce of .2 sounds suspichiously like a ground issue, make sure all grounds for ECM and wideband are good and clean to same engine block surface.

 

Yes, this is likely. I will check it first. Also, I noticed there is a formula in the converson (in the adx) for afr display. I checked with my MTX-L's manual and the bottom end afr is the same as the formula, 7.35. But maybe it's still in the math somewhere.

And if 0x35 is for shift light why were we directed to change 0x34 to 0x35? I suppose it's a mute point now but I spent a lot of time chasing my tail at the 0x35 location. From my experiance anyone using this WB bin/adx should leave it at 0x34 to start.

 

I don't know but you were directed there by someone who is very good with this stuff and I read his posts and watch his work, so I am curious too?

For instance, look at the dashboards now in the adx, JP made most of them, I collected them and some others and cut and paste them in adx files. Just have to right click and choose the value for each gauge to what you want.

The conversion math on WB was close, unless my math is off I corrected it.

I noticed that in the ads import to adx there are no pause or extra byte in return command? Not sure this is needed in $6E like others for glitch free data. There is also an updated TunerPro out and I don't know if this was addressed? So may have to add a pause or byte, the $6E guys will know.

 

Thanks, will check it out. And I must clarify, I am only curious as to why it is/was/may be necessary. I am in NOOO way implying that someone was wrong or didn't know what to do. I am so ignorant to most of what is going on in the background. There's "more than meets the eye" and I am attempting to understand.

I have tuned many cars via seat of the pants, drag times and typical hot rodding gauges and tools. I'd like to think I was pretty competent among the hobby crowd. Most of my work was pre-computer and I'm an old fart really behind the times when it comes to computers in general and computer tuning. I'm still making the association between things like power valves in Holleys and PE enrichment lol. You get the idea.

My deepest appreciation and respect goes out to all of you in this forum. I have learned more here and tweeking my old 'Roc than I had in years and years of changing accelerator pump cams, distributor springs and looking curiously at spark plug through my loop!
