i'm using the bin file axxdwb from z69 and i set 37 for the aldl and it's reading 160.00 something, it's not close to the afr, what am i doing wrong?

 

It may be correct - the way it displays the AFR is you have to divide the displayed value by 10 to get the actual AFR. So a display of 160 is AFR of 16.0, a 147 display would be 14.7 AFR. Hope this helps.......

 

Also be sure to set the output of the LC-1 to 1-2 volt range using the Innovate sensor selection bit. Might have it defaulted to the 5 v range and its out of range.
Set the "input pin select" bit to match the connection point depending on which pin you are using.

 

in tunerpro i checked wb opt 1 sensor select bit 5 for innovate, do i have to select anything under wb opt 2 select sensor and pin? the wb is in map 2 it was working fine under the $58 code, although i do think i had the lc-1 set default 1-5v

 

You need to do two things :
1) Set memory location 0x2001 to 0x00
2) Make sure there is only one bit set in 0x2000. For your LC-1, it should be Bit #5.

This should enable reading and output of the WB sensor.

If you still have problems after setting the above, you might want to enable the "Raw Output" option (0x2000 = 0x00, 0x2001 = 0x01) to see the number of counts being read by the ECM. Compare this value to a reading obtained on a multimeter at the MAP2 pin. The ECM ALDL value should equal 255 * (Mulitmeter voltage / 5). I.e. a reading of 2.5 volts should be 127 or 128 counts. If the two are equal, you either have a bad sensor or the engine is at the AFR the sensor is indicating!

 

Quick question for those who have succesfully integrated the wideband output into the ECM. How exactly did you connect the wideband output with the ECM? Are you doing it internally or at athe connector? Did you get a connector from the boneyard and use one of the pins? Any help appreciated. Pics would be great also. Thanks.

 

I transplanted my ECM into the car. So, I used connectors from the junkyard with ~6 inches of wire attached. From there, I just spliced the sensor wires into the connector pigtails.

 

I did the exact same thing. Used wires from an old connector, spliced that to the WB output wire, and plugged it into the ECM connector.

 

Thanks for the fast replies! Looks like i'm going to the boneyard soon.

 

guys i cant get this to work for some reason, it worked in $58 i got my LC1 Analog out 2 into map2 on the ecm, i set the LC-1 for 1-2volts

i'm using the axxdwb.bin file, and i set the innov bit, and i followed someones instructions to add the min iac output to the aldl file, and i get readings that dont match the lm programmer readings. can someone give me a step by step, maybe i'm not doing something right, do you have to do anything with the option2 stuff in the xdf?

 

i tried again today the lmprogrammer is showing 12.1 in tunerpro its showing 160 i must be doing something wrong, who else has this working with an lc-1?

 

160 sounds like the IAC steps that would be there if you were not using the patched bin.
Double check your bin against a stock one in TP to confirm there is a change at the location where the word is in the datastream. Should be somewhere around 8915 (0915 in the compare table)

Could be 0916, look for something in that area (not sure on that bin)
The value should be 2D in the original bin (IAC counts) and 35 in the patched one (WB value).
That will show the WB at word #37 in the ALDL definition.
HTH

 

ok checked it, it has a 0035 at 915-916, i dont get it, the wb works great on the $58 code but i'm not using the $58 right now.

 

DOH! thanks guys i set it for 0-2v, i set it to 1-2v and now it works

 

Glad you got it working
