ok, I've tried to figgure this out for 2 weeks and I've burnt out over it. I'm stil trying to get dataloggin working with Uberdata 1.70, I havn't tried ECU control yet, I just found out about it today. My problem, my datalogging IS working, but my ecu isn't getting the narrowband signal from from my Innovaative LM-1 Wideband. So, it has nothing to do with my datalogging cable because I'm getting the correct rpm values and temps, ect...., so please don't waste your time and tell me that. So far I have Programed my Lm-1 analog outputs to match my Uberdata 1.70 version voltage readings. I programed them to 0v 7.29 a/f
5v 22.09 a/f
then I checked the voltage from analog wire from wb and it read 2.52 and would fluxuate alitle if I hit the gas. I also checked the connection to d14, it's great, I sodered it and the voltage reads the same there. The Stock o2 wire is cut in 1/2, with red analog wire hooked up to the wire that comes off the ecu, d14 (red with white line), checked it lke 6 times according to this link... http://www.plxdevices.com/ECUDatabase/H ... _92_95.pdf
then I grounded it out about 1 inch from ecu on A24 (black wire) then pluged the the analog wire into analog spot on WB. I also have tried hooking the other analog wire off the wb to the d14 pin. I have also checked where the d14 wire goes into the gray ecu connector and it's in there tight. I have also played with the datalogging txt doc in Uberdata and changing the numbers in the void timer part did not help either. When I start datalogging, I will click on low fuel map and lambda log and rpm is working but all the boxes just fill up with 18.63 which means the ecu isn't getting the wb's signal. I have run out of ideas, can anyone help.I can't think of ANYTHING else to do.

isn't the narrowband signal 0-1v?

Same problem, but with stock O2 sensor. Shouldnt the stock O2 still read even if its not accurate? All the other guages work, but no a/f readings and the charts dont fill.

I don't know much anout OBD1 and if there are different series of NGs but in my OBD0 I have the same when using NG60 rom, but when I us NG55 everything works - it logs correct voltage
