'99 XK8 OBDII Protocol?
Hi everyone.
I'm hoping someone can answer this, because my research is bupkiss.
I have a 1999 XK8 convertible. I have used my older OBDII bluetooth adapter and a brand new OBDII bluetooth adapter in my cat, but neither can talk to my ECU.
What protocol do I need for my OBDII adapter(s) to have to communicate with my ECU? Worked great on my '98 Lincoln Mark VIII LSC.
They both connect just fine to my smartphone (using Torque) but both give errors saying they cannot communicate with my ECU, and I cannot find definitive tech data to sufficiently identify what protocol the ECU uses.
Thanks in advance!

My Torque Pro app links right up to the ELM 327 bluetooth converter without manual intervention . . . but . . . I have 3 other converters in the junk box that do not work. The Chinese knock offs are famous for being DOA or shortly there after. The eBay vendors will give your money back instantly as this is a well known problem.

Some of the elm327s are clones and don't work, though. You need engine running or ignition II.

With USB connected ELM devices it is possible to control the chip directly from a simple terminal program thereby bypassing the supplied program.
This would allow you to check if the chip (only) is searching and using the corrrect protocol.
I don't know if a modified technique is possible with a Bluetooth device though.
Whether or not the Chinese junk is a mirror image of a genuine ELM device or a botched homebrew version I don't know - any ideas from others?

A BT OBDII Adapter that actually works?

I'm in the same boat with 3 BT adapters that don't work on my 99 XK8.
Can anyone recommend one they have that works?
There seems to be no way to tell via the web which one FOR CERTAIN is a true ELM v1.5 compliant adapter.
I saw a specific recommendation but AmazonUK won't ship to the US.

After reading all posts about bad ELM adapters , I spent the extra money to get the PLX KIWI adapter. Never had a problem with it.

I looked at the KIWI PLX, but had a couple concerns.
1st, a 3' cord? Why? The OBDII port is big enough to hold on of the larger BT adapters. That means I have to tie it up in such a way that won't get caught by my feet. I have some significant mobility issues.
2nd, it has a button I have to press to turn it on?

The on/off feature is a positive to people that like to leave the scanner in their car for live monitoring while they're driving
The on/off button allows them to not have to remove and replace the scanner to turn it off or on everyday, so they just leave it plugged in all the time and turn it on before getting on the road then turn it off when leaving the vehicle
It's a matter of convenience and less wear on the connector.

I like the on/off feature.
