Tesing of new code.
Hello all
I have written a few lines of code into the aujp prom to allow for datalogging of the wideband o2 using Craigs software. It runs on the simulator but this does not mean it will run in the 7730. I need help testing it. The WB signal will be input on pin A3 and will be seen as the canister purge signal. The standard 0 - 255 = 0-5V applies. I have attached the bin if anyone wants to look at it or try it out.
Thanks in advance for tips or tricks

What ever happened to this? Are people still working on this? I am saving up for a WB O2. I am very interested in this idea of adding the WB O2 to the ALDL data stream.

Would it be possible to use one of the other pins that the SD V6s use but are FREE on the SD V8s? Like D13 which is the input for the Power Steering switch that only exists on the $88 V6 calibration. The actual "driver" for D13 exists in ALL 7730 ECMs. This would allow ALL SD users, including those retaining all their emission equipment to take advantage of this change.
Alternatively, there is D12, the "High Pressure A/C Switch" for Fan 2. In the AUJP code, this switch is ONLY informational, the calibration doesn't really do much with it as the 7730 cannot turn on Fan2. I've "manually" set it on and found no differences in the operation of my engine except for my scan tool reporting "FAN 2 Request On" (even though Fan 2 still was not on). I did a lot of testing on Fan 2 and basically the input does nothing other than "reporting" from what I've can see.
Lastly, how about some "outputs"? I have found an output F5 from the V6 that is for a "Third EGR Solenoid Control" that is not used on the SD V8 calibration. I am thinking that this would be a dandy one to use to FINALLY make the ECM actually control Fan 2 via the CTS or other criteria like A/C, Temp and VSS....like I truly believe the ECM was intended to have, but go "nixed" by someone in GM. I guess someone at GM didn't want too much "reliance" on these "new fangled computers and wanted a "hardware solution" incase the ECM/software didn't function properly.

no man the fan thing was al QC. they f'd up. if you have an open
swtich on yr ecm can adress it direct the ecm to turn it on. you have the code you have the know how.

Thank You

I think you misunderstand what I did. I have taken the input on pin A3 (an unused a/d port) and used that to get the voltage into the computer. I did not disable the CCP I only used the byte reserved for it in the ALDL stream. Emmision comliance is fully retained.
I am currently working on version 2.0. It will look up A/F ratio from a table and output it to the Batt voltage Byte so that A/F ratios will be displayed correctly. The No CCP data was never a problem because I always turned it off to tune.

First, I think this is really useful, what you've done! Thanks for sharing!
I noted that you have a 25.x lb/hr injector constant, and that you have VATS disabled, when compared to AUJP1615. Let us know if I am mistaken, but the testers might want to note this (If they're like me, they investigated first
Third, a question...AFAIK, the good ol 1-wire GM o2 sensor chemically produces about a 0 - 1v signal based on the lack of o2 running down the pipe... On your test bench, are you using a directly connected WB, a GM o2, a "DIY_WB board"'s output? or just a pot(wiper from a TPS?)
After I look at what you have at $2000 for a bit (looks like might be chip channel select and sensor read?), I'll test it out with a spare TPS and let you know if my aldl package sees it... I assume you've written it to the datastream, therefore any package that grabs the canister P% will see it, not only Moates. I may be a while before I get back with the results, but I will.
Lastly... something neet to think about doing.. spare OUTPUT! yuummm... :-))
thanks again!

You are correct. I would hope that everyone would look at whats on a bin before just burning it and trying it. This was kind of meant as a key on but engine not running test.

I plugged in values to a hc11 simulator. Later I used a wiper for testing as the WBO2 output can not easily be varied though the whole range.
After I look at what you have at $2000 for a bit (looks like might be chip channel select and sensor read?)
That is exactly what I did. The WB output is 0-5VDC the same as TPS or MAP. Using a spare channel meant that all that was necessary was to read the channel. Then I stored the value in a spare RAM location and changed the CCP ALDL byte to read that RAM location.
Good luck with it

To be clear, are you saying the WB itself is 0-5v, or the COMPLETE DIY_WB setup is 0-5v?
thanks.

I started poking at the code patch you made, and after I documented what you did I have a couple questions... (I still have not tried it on the car, I have to port it over to my application exactly)
Q1: I see nothing done to the datastream in the chip. What VIN are you using with the software (moates, I'm not familiar with its operation sorry but I have been wanting to get set up with it ) to get location $0034 to spit out? It does not look (codewise) that it will ever spit out of the datastream but again, I have not put it on the car. I plan on changing some things beyond what you have done so if you tested on a hc11 simulator and looked at the ram location directly and saw it working... I still need to take it foreward to the datastrteam.
(edit: - OK, I re-read more.... if $0034 is already in the datastream then that's why there are no changes there. "Canister purge" huh... ok!.. but isn't that written-to in the code already?) - I'll shut up now.. this post is almost moot except that I say I'm working on it!)
Q2: I can go look this up, but what PIN is channel 0 on?
(duuh-- A3 - I re-read the thread.. nevermind) :/
PS, whats version 2? Did you address any of the above? I don't see a reference to version 2 in this thread.... ?
{edit: (smack) I see that now too.. I think the WB is *nearly* linear... might be close but never perfect}
Thanks again and I hope to have results for you at some point.

Did someone get the WB02 logging to work with a 165 / 6E hack? I missed it I guess...
...but would be interested...

Question,
is the checksum disabled on the 8dwbo2.bin.
I was making some changes to the TCC at 0x610F and was wondering if the checksum needs to be recalculated.
TunerCat's CS utility dosen't seem to work with this 8dwb02.bin or mabey its been disabled.

If the prom ID is located here it looks like its set to 8A.
0000: 8A C6 L0000 ORAA #$00C6 ;..
L0001
0002: FF FF FF STX LFFFF ;...
When I run the TunerCat CS program with the WBO2 bin
nothing shows up at all on the screen, works fine with my .bin files

32V_DOHC,
I just finished Installing and hooking up my DIY WB and transfered all my settings to your 8dwbo2 bin and my Vout to A3.
It works just as avertised, really cool stuff its going to make data loging and tuning a breeze.
thanks for all the info.
Any more work being done on ver. 2

This is great stuff.
Ok have it all hooked up and running, I show a CCP vout value of 51 and the WB02 A/F meter is showing 14.6 to 14.7 at Idle I show a CCP vout value of 48 and the A/F meter shows 13.8.
How do I calculate the A/F ratio.
is this how it works
CCP values 0-255 = 0-5v
So that being that 255/5 = 51
CCP vout value 1 = .0490196 vlts
so I just Multiply the CCP value by .0490196 and that = the Vout and that converts to AFR using the chart.
if thats so.
Then a CCP value of 40 X .0490196 = AFR of 11.96.
Dose this sound correct.

Mike has hacked the following calibration using 32V_DOHC info:
$8D - AUJP ('92 TPI 350 w/A4)
$8D - AXXC ('92 TPI 305 w/M5)
$6E - ARAP ('89 TPI 350 w/A4)
$6E - APYP ('89 TPI 350 {vette} w/M6)
You can download the bin’s here:

I've got it working with a few mods to the 6E code. Just bring it into MAP2 and route it to MAT2 on the ALDL stream. Or I guess you could just send it as requested AFR same as the 730 deal...

Hey guys. I am code stupid but a longtime programmer. What all do I need to do this and can someone explain what this is actually going to do and how I will receive the WB data?

I haven't done anything with this yet but plan on it. I guess the first step is compairing the code between this .bin and the stock AUJP to see how they put this additional table in there. Or if someone has an ECU that has that table it would make my life easier...????
Never played with code before.

Hac for AXXC WB
I tried it and it worked great, it read out on the Datamaster air-fuel value box. I use it with the LM-1 WB. Only now I have a problem, the next time I hooked it up I can't link from the ALDL connector with anything I try (Datamaster, Diacom, OTC) I have tried different PROM's and everything, adding the WB hac and removing and reinstalling ...nothing works anymore. Until I put back the regular PROM (29c256) I have been using, then everything is fine (but with no WB).

Just to confirm, the output of a WB02 system is being wired to an ECM pin, not just a wide band lambda probe?
