Hi, I received my kit# 1 and got some problems.

1. The nanologger sketch is too big during loading. I have tried it with arduino 1.6.5, however you wrote to try it with arduino 1.5 I will try to find that version and try that one.
2 I connected everything according the schemes on the web. I loaded the nanotimmer on the nano.
I connect the uart to the obd port, it blinks, the nano blinks aswell but the OLED doesn't turn on. It remains black.

I checked the connections many times,
vcc- 3.3v
ground- ground
scl-a5
sda-a4

I will try new wires, altought I don't think it is the problem
any suggestions?

Thanks in advance.

gdg,
If you haven’t installed the microSD card breakout then you don’t need the data logging features. Go to “config.h”, line 8 where it “#define ENABLE_DATA_LOG 1” and change it to “#define ENABLE_DATA_LOG 0”. Compile and upload the sketch.

Coytar,

Thank you very much! you made my day.
Now it works, and i discovered that I had to change the lcd type in the config.h aswell.

oled works fine now.
However I discovered that the throttle % stays at 0% the whole time
WIth an elm327 or VCDS I can see the throttle percentage with no problem, but that is another story.
WIll see if I can figure it out.

Again many thanks coytar!
