Wide band data into HP VCM Scanner

Hopefully you guys can help me. I've spent countless hours and i've tried everything under the sun when it comes to getting my AFR readings from my LM-2 wideband into hp tuners. I've read and tried all the things you guys recommend, i've tried the serial cable to usb adapter and still the data shows up maybe once out of 50 trys. my laptop is up to date, all my software is up to date ,unless I'm missing something is there anything else you can recommend? also is it possible to just wire the wide band sensor directly to my pro link adaptor? Or maybe wire an analog adaptor out of the LM-2 to my hp tuners pro link cable which has analog inputs? I'm lost and have a vehicle that I need to re-scale the MAF and trying to do so using the eq-error ratio and I cant do that with out a wide band reading.

Thanks in advance

I admit that the LM2 integration is flaky at best and I've spent more than my fair share of time pulling my hair out. That being said, the two tricks that I used to improve my reliability was to use the square 4 pin LM2-serial cable from innovate rather than the actual USB outlet on the LM2 case, and it also seems very sensitive to the type of serial/USB adaptor. i got the best results with an ATEN brand.

With the pro link adaptor and the pro feature set you could wire the LM2 direct to your adaptor, however while I haven't done this on the MPVI2, on the earlier interface it was very sensitive to ground offsets and this was a whole separate ball ache to work through.I've moved away from the LM2 though and now use the AEM X-Series wideband which has pass through CAN communication via the OBD2 port. This gets you away from issues with ground offsets too and ensures the integrity of the data.

Thanks for the replay Andre,

With the AEM Will that work with pre can vehicle pre 2006/2007 I work on a lot of LS swapped vehicles that use early LIN/LAN low speed communication.

I need to figure something out because at the moment I’m using STFT to get in the ball park but I can’t do any accurate open loop tuning with out having the AFR logged in VCM while being able to see MAF HZ. There has to be a better way than spending days on end driving logging and tweaking MAF scaling just to get it in the ball park. It would be a game changer to have eq error ratios

thanks again

That's a good question and one that I don't have a solid answer for unfortunately since I haven't used it on a pre-CAN vehicle. I don't see why it wouldn't though since the OBD2 pass through connector doesn't rely on the OE CAN bus so the wideband message would be present irrespective. I've found the AEM X-Series gauge to be really good and the communication to the scanner has been rock solid.
