let me know what you see when you get it.
If it does not have an external serial comms port, then I do apologize, it looks to me like it does.

Look at callout # 5 under Technical Specs:
Wideband-O2-Air-Fuel-Ratio-Sensor-Module-p/897346002726
It does have serial output, but it's not compatible with EFI Live.
I tried to get it to work, but couldn't get it operational with the serial port. Analog works fine. I ordered the RS-232 TTL converter. It was only $4 bucks, and if I can't get it working that way, I'll just use the analog inputs.
FYI this is the latest version of the PLX SM-AFR, GEN 4.
Hmmm, that is a bummer...
do you have any output captured from the serial port (e.g. in a HyperTerm or PuTTY window after playing with speed/parity/stopbits)...?
And I do apologize, for some reason I had understood it to be compatible at the serial port socket.
No biggie Joe. I have everything working fine with the analog inputs.
I fitted twin PLX SM-AFR Gen4, Bosch LSU 4.2 sensors with twin gauges a couple of months ago (with help !), currently use the 0-5v analog output to feed into a HPtuners MPVI
data logger...seems to work fine. I was hoping to use same way to connect to my Flashcan V2 when I eventually migrate to a EFILive tune. Have to say with my limited experience
the response times look very fast.
Stumbled accross this thread........are the analog signals really that bad ??
UK spec 2009 HSV VXR8 6.2 LS3, E38, HeartBeat Supercharger running ~9psi,1 7/8" long tubes, cat back exhaust.
Upgraded cam and springs of unknown specification, all I know is, it's a small cam with no overlap, suits the s/c.
ATI damper, LS9 twin plate clutch, 548rwhp. twin PLX widebands to twin gauges.
Currently running dismal HPTuners....NOW DUMPED !, Completed migration to EFIlive and slowly mapping it in.
628rwhp.....with a lot of tuner help
Not typically... we just like to use serial comms wherever it is supported (for various reasons).
i've got one in a drag car. it reads 1 afr leaner through the analog over the serial/guage display.
it came with the car when we purchased it, but wont be in it very soon.
Please can somebody point me towards the guide for setting up the analog 5v pids for plx wb's, specifically how to program the V2 aswell ?
Thankyou.
