1. The display unit is unstable, and cycles through colours and jumps around quite a lot
2. When it's readable the actual values are FAR too unstable, you can get the idea of water temp etc but nothing too accurate. It will go from 75 to 85 back down then oscillate around. There seems to be no smoothing out of the values - and physical water temps don't fluctuate that rapidly.
You can see these issues here
however it seems to be behaving itself today, the colours are only flickering at the top of the screen and the values are relatively stable.
3. EGT doesn't work properly. When i boot it the display goes to 990 degrees C which is crazy, then stays there for a good few seconds after I come off the throttle.
4. The screen is far too reflective so you can forget about daytime use unless you mount it somewhere really out of the way. I did have mine in the 60mm clock hole (facelift) in the centre console but was unusable. It's now "OK" in daytime now that I have mounted it in the right hand climate control vent.
Now, these may be simple problems that can be sorted out, but I have had NO HELP from PLX, last time I rang I was told to send an email to a guy called Nick, so I send a long email and had no response whatsoever.
I've basically given up with having everything sorted out which is a shame.
