Re-reading your response and yes, it happens when I hit run to restart the script but I only get the error when I change the pulse to any value below 1. If the value is 1 or greater it works fine as you can see prior to the error as once three error is thrown the script stops running. What error do ...

Brent, I have the RPM lead connected but it was displaying half of the RPM value and when trying to set the pulse to half it would lose the channel and error out. This happened when trying to set it to anything below 1. What I ended up doing was multiplying it by 2 in my Lua Script to get the shiftx...

Brent, I upgraded the firmware to 2.11.0 and increased the frequency to 50Hz and the RPM's stopped displaying in the dashboard but I couldn't mess with it as I had to get to grid. The car is very loud so I try not to turn it on in the neighborhood (non street legal). I've wired a shift light before ...

Brent, I continue to be plagued by this issue where it only reads the RPM every so often and the biggest problem is that as the car is moving up in the RPM's it only reads it every 400 RPM's or so which is an issue. I didn't have this problem when using EcuTek for logging on my other Miata. Below is...

A PID read error means RCP did not receive a response from the ECU. Worth noting, the ECU can only service one PID request at a time. Do you have OBDII channels also enabled in the top level configuration? If you don't have the top level OBDII configuration enabled, could you enable that for say, R...

OBD2: PID read fail:
I'm seeing numerous OBD2: PID read fail: errors when polling the log (1 every 3 seconds) and it seems to get worse the more PID's I try to query. I increased the tick rate to 25 and it helped a little. Is this a bug or is there a wiring issue somewhere? I'm running RC Pro MK2 2.10.2?

Thanks Brent, you are correct the issue is that at times it's failing to obtain a reading for that PID and returning the nil value. I modified the script to account for a nil value but why am I seeing so many OBD2: PID read fail errors? I seem to get one every 3 seconds or so and it does'n t matter ...

Only Works on first run
I'm just getting started with Race Capture and want to output the data to the console to later build other scripts and when the script runs the first time it shows the correct value which is 0 for RPM and 127 for engine temperature but then it states that it can't read the values for several iterati...
