I'm considering the following to use with my 730 ECM:

http://www.moates.net/product_info.p...products_id=88

Is this a valid option?

Any pointers on where to get the info to do this? Wiring changes? I figure I can find the aujp version that uses the wide band and modify my bin, however, I need to find the necessary wiring changes. I did a search but most of the info seems relatively old.

 

That's what I run on my 91 with the 730. It has two programable outputs either of which can be made to replicate the stock 0-1 volt signal. Wiring is easy, solid switched 12V and clean engine ground.

I added a second 02 bung but ended up putting the WB in the stock location.

I pulled the bulkhead connector and added the extra wires to the factory harness.

consider the http://www.moates.net/product_info.p...roducts_id=103
and you would have programable realtime (very close to realtime anyway) AF display.

 

I must say it is fairly worthless...other than letting you know when you're crossing over. This looked good since it says that will supply analog outputs, which I suppose include a simulated NB signal?

Is there a manner to wire this into the 730 ECM so it uses this instead of the Narrow Band? If so, where would I find such info?

 

It will display what your AF ratio is, what do you mean worthless?

Yes, it has two programable outputs, either can be used to replace the stock NB's output.

It will come in the box with the unit or you can download it from http://www.innovatemotorsports.com/s...LM1_Manual.pdf. In either event you plug the analog output into the O2 Sensor wire and go. If you use the connector off of an old O2 sensor you can plug it in just like the NB sensor plugged in.

 

the LC-1 has 2 separate analog outputs, I can use one of those for my analog NB gauge, and the other I can use directly as an input to my 730 ECM?

That just sounds too easy!

What I meant by worthless on my NB analog gauge is that it only lets you that you're crossing over...not that there is anything wrong with the gauge, it just doesn't really help for tuning. It sounds like this LC-1 unit would be able to feed an input into the gauge. I really like the gauge because it is analog and kinda matches the rest of my gauges. I bought it off a friend of mine who didn't want to play with cars anymore:

You can use the same output for both your NB gauge and your ECM or you can use the two outputs separately. Personally I would ditch that unit for the one I linked to. It reads the actual AF ratio based on the WB 0-5 volt output.

If you look at the graph on page 13 of http://www.innovatemotorsports.com/s...LM1_Manual.pdf
you can see what a narrow range of the available spectrum you are limiting yourself to.

 

is there a way for the 730 ECM to use the "wide" band application of the wide band sensor? Or is all the tuning done with an independent meter but the 730 still uses the NB signal?

I was reading the LC-1 manual:

http://www.innovatemotorsports.com/s...C-1_Manual.pdf

It says to connect the output to serial port on your laptop....are there any laptops even made with serial ports nowadays?
I don't really want to buy another WB Gauge, so I guess I could use a digital multimeter to monitor wideband.

 

You can use a USB-Serial adapter if your laptop does not have a serial connector. You can log the wideband data to your laptop to do your tuning.

The ECM only needs the NB signal to do its job as it only works around the 14.7:1 area.

 

So, I really don't have to do anything special to MY 730 BIN? I had always previously imagined that something had to be done.

 

Nope, you need do nothing to the bin.

 

there is a way you can wire the wide band output to the ECM for data logging in TunerPro,
https://www.thirdgen.org/forums/diy-...-new-code.html

but even with the wide band patch, you still must have the narrow band output hooked up to the O2 sensor input to the ECM for fuel control.

i haven't been able to get the WB patch to work quite right with my ZT2, but it seems with the LC1 or LM1 it works fine.

 

So... You can totally ditch the NB for WB and datalog the wideband through ALDL with TunerPro but the ECU will only use NB "area" to make fuel corrections. Am I understanding this correctly? Would this be wise to do?

 

I have a Moates APU1 with my wideband output wired into it. It merges the WB with the datastream so no need to for me to hack my ECM.

I use the NB output from my WB as input to my ECM on my daily driver. It is more accurate than my NB ever was.

 

So I wire the WB input to Pin A-3 and then when I datalog on TunerproRT I can actually capture the wide band value? That just sounds too beautiful!

So, I figure that I can copy that BIN mentioned in the link and make the necessary changes so it matches mine and it's all good to go? I had disabled all the CCP stuff in my BIN since I don't need any emissions stuff....I gather that I'd have to re-enable some of the CCP stuff?

 

I haven't been able to get that bin to unzip. Some sort of archive issue.
It's been 3 weeks now that i've been trying to get my WB to work through TP. No luck as of yet.

 

if you want, let me know, and I'll send you the one I just unzipped.

 

Please do. Maybe my zipper is having issues.

Thanks

 

let me know if you identify the location of the change for the WBO2...I've gotta figure out where to look.

 

Will do. I'll try it in the car with some minor changes in a few minutes.

 

No luck. I must be doing something wrong. ZT-2 reads ~12.2 and the ECM is reading ~14.3 with BLM and INT bottomed out.

 

I have an LC-1 datalogging into my 730 but so far it doesn't seem to want to correlate to the stock NB O2... It tends to read really lean when the stock NB O2 (BLMs) are near stoich - and the engine tells me that the BLMs are correct and not the LC-1. As in exhaust smell, eye burning, plug read, etc). I am still troubleshooting right now, but I am not the only one to encounter this. I do not recommend using the LC-1 to simulate your NB O2 to run your engine. At least not until you really know it is reading an air fuel ratio that is correct.

I have one output logging in the datastream and the simulated NB O2 output running an Autometer air fuel ratio gauge (the one made to run off a standard NB O2, with different colored LEDs). The datastream LC-1 air fuel ratio and the Autometer gauge readings correlate perfectly.

I attached a zipped file with the Super AUJP .bins and ecu file for use with the wide band patch already installed. Read the text files in them for details on getting the LC-1 to show up in the datastream and what pin to use for the LC-1 input. It should be F14 for use with this patched .bin file. It works perfectly on my car.

 

I downloaded the info and was reading the text files. I believe I understand the predominant message throughout, but I did NOT understand what statement #7 is about:

"7)The S19_PAT command line would be:

s19_pat xxxxwb.s19 0x8000 File2Patch.bin x=BCC used
I used ashc11 assembler for the patch.
You may need to rename the patch to something less than 9 characters.
One way to apply the patch is to move your bin, the s19 file and S19_pat.exe to the root directory.
Then go to the start menu and select run. And type c:\ and the command line above.
example- c:\s19_pat aujpwb.s19 0x8000 mybintopatch.bin"

Would you please explain to me (in bonehead terms would be best....so I can understand!). Thanks

 

Are you trying to apply the patch to an existing .bin? If so, I did not do it that way so I can't give you an experienced take on how to do that... I used the supplied AUJP Version 3 with Wide Band patch already installed and then configured the constants and table calibrations to what I had from a previous tune for my engine. Using TunerPro, it is easy to compare the fields in one .bin to another (3 actually) and set them accordingly.

But it seems straight forward to me... Put the .bin you want to patch and the S19_PAT.exe and aujpwb.s19 files in the C: drive root directory (as in not in any other folders, just in C. Then go to the command prompt (in WinXP go to Start, All Programs, Accessories, then click on Command Prompt) and type that sequence of commands... The executable, then the actual patch file (the .s19 one), then the hex number 0x8000 and then the name of the .bin file you are patching the Wide Band patch into.

I assume you are using an AUJP based .bin file? This will work with a couple others, but you need the appropriate .s19 file for each one.

 

but I can, since it's so easy to make adaptations in Tunerpro. Ok, I understand the purpose of the S19_PAT.exe. Thanks.

 

I thought the manufacturer says that it needs to be off during engine cranking. I heard a few people talking about the controller croaking due to engine crank voltage. You might want to look into that before your WBO2 controller stops working.

 

I read that as well. I ran mine off the radio fuse power circuit which cuts out during cranking to avoid any issues.

 

Ditto on the radio power circuit.

Using the WB inserted into the ALDL datastream together with ScannerPro is a dream come true.
