yes you can have the haltech datalog the voltage and have the gauge......that new gauge is nice i might have to order it lol

 

where do you get the sensor and controller?
and about how much will it cost?

 

well I've still been researching around, and so far it sounds like the Megasquirt guys are developing a WB02 controller that can interface with EMS's and using the LSU4 sensor which can be had for $30. I'm gonna keep an eye on its progress. The big issue seems to be with controlling the heating of the WB, its very important.

 

You can pick up the bosch wide band sensor cheaper from the VW dealer.

 

Cheaper than $30?

 

 

scope www.wbo2.com

 

I was looking at their site before but was a little confused about how all this hooks up...so If I buy the "WBo2 (2.0) unit & cable only (for 7057)" and the 7057 VW o2 sensor, I can use the Spare A/D or Trim inputs to connect my E6K to the WBo2 unit and display and datalog the readings?

 

PvillKnight7, That's how I have it mine setup (for the most part.)

 

So your WB has to be linear? If its not linear can you still hook your WB up??

 

Well my new plan is to get the M-300 from www.plxdevices.com and use its linear analog output to the E6K. Are ya'll using the spare A/D input or the O2 sensor signal wire, and when you datalog are you able to get A/F ratios or just voltage display? thx... look for the updates on this.

 

Does anybody know how to get the datalog to display AFR numbers instead of voltage? Or just do the simple (voltage * 2) + 9 routine? thx

 

Im running the plx m300 also, has anyone hooked this up yet to there e6k? It has two extra wires that can go to a computer, one is narrow band and other is wide. Rotarysc, let me know if you figure somethin out.

thanks

yeah just run the wide band to the spare A/D input wire (3 prong connector by the ECU itself... two of them so be sure to get the right one, use schematic to determ color) then enable it in the software.... Still gotta figure out if there's a way to display as an AFR.

 

I am also wanting to hook up the M-300, but I am using the spare for the aux-rpm. Is there another way to hook it up, without using the spare.

 

Could I hook the white wire (wideband) directly to the grey o2 wire on the Halteck? Would it read correctly?

 

You can hook the analog narrowband output of the M-300 to the Haltech O2 wire, yes... just make sure the M-300 and Haltech have good grounds so that they're on the same level.

 

here's a calculator I found on their site for figuring out AFR based on the 0-5v aux input in datalogs.

Here is how you data log from the PLX Device M300 to the E6K:

-On the M300 connect the red wire to 12V ignition power.

-On the M300 connect the black wire to the same ground location as your E6K ground cable.

-Connect the wide band wire (white 20 gauge wire) from the M300 to the Spare A/D wire on the E6k (that would be the Red\Blk wire on the Spare A/D connector)

-You will NOT USE the Blk (ground) wire on the Spare A/D Connector

-You will NOT USE the Org (+5VDC) wire on the Spare A/D Connector

-Connect your laptop to the E6K (thru the serial cable), run the haltech program, and connect to the E6K.

-Go to Input/Output Setup (Ctrl + N):
1 - Highlight Spare Input Function
2 - Click the Tab Key on the keyboard
3 - Select General
4 - Turn off the engine (or accessories power if you didn't start the engine in order to connect online to the E6K)
5 - Start your engine, and verify that you can see the voltage of the wide band on the Engine Data Page (Ctrl + E)

- In order to data log it, you will need to remove one of the data log "Displayed Data" option, since the E6K will only allow for "UP TO" 8 Displayed Data. Since I know that the Battery Voltage is ok, I removed that one for tuning purposes, and added up the Spare A/D.

- In order to get to the Displayed Data page and select the Spare A/D, you will:

1 - Go to "Data Log" (Ctrl + D) under options.
2 - Select Data Log to Disk.
3 - Select "Config" by pressing the letter C on your the keyboard.
4 - Under "Displayed Data" highlight Battery Voltage and press the "Enter" key on the keyboard. Noticed how "Battery Voltage" now shows at the "Non-Displayed Data"
5 - Under "Non-Displayed Data", select "Spare A/D" and press the "Enter" key, Noticed how "Battery Voltage" now shows at the "Displayed Data"
6 - Click the "Esc" key on your keyboard, and start data logging.

***I just finished this late last night, so I haven't been able to data log anything yet, just see it on the engine data page.

***The wide band info will be shown as voltage on the data log and\or engine data page. My plan is to import the data page into a spreadsheet, and convert the voltage to AFR (2 * voltage + 10)

***If anybody knows how to setup the formula on the E6K so that it will be converted automatically on the data log and\or engine data page, please feel free to help!

***I know that the instructions are VERY basic, but I also know that it might save somebody a couple of minutes or maybe hours of researching

 

Great write up bro, this is exactly how I told a friend via phone to hook it up and it works great, thx for taking the time to document this thoroughly it will be very helpful to people of all skill level. As far as converting AFR its pretty easy to convert in your head once your familiar with it, you'll know where you wanna be voltage wise.

 

Is there another way of hooking it up? I use the aux for the 2 step when launching.

 

I went ahead and got the whole FJO kit , it has a 0 - 5 volt analog output, can this output be connected to the signal wire of the O2 sensor connector and just select the 5 wire sensor option ?

 

You can get a switch to just toggle between options.
