    You could alternatively use an external Analog to Digital converter that has a higher resolution; there are cheap 16 bit i2c AD chips available; integrate that on the board and have the communications between the board and the Arduino just be digital could be very interesting.

    I definitely would recommend some changes to PCB.Start with a standard Arduino Shield Layout and make sure it fits on that. The current layout was just a linear line that made sure the pins would plug into a an Arduino directly. But at least for the smaller boards (non-Mega) it hangs out the end and also isn't secured with the other pins. With this I would also add a few pins to the other side just for mechanical structure when connected to the Arduino.For my motorcycle, the vacuum did exceed the range but only when I increase the throttle to near 66% which happens only quickly (blip of the throttle) and isn't really needed when synchronizing. Vacuum at 50% throttle should be fine and most instructions don't even ask you do anything other than idle.When ever you increase the range ...see more »I definitely would recommend some changes to PCB.Start with a standard Arduino Shield Layout and make sure it fits on that.

Vacuum at 50% throttle should be fine and most instructions don't even ask you do anything other than idle.When ever you increase the range of the sensor, you decrease the resolution of the readings. The Arduino only has 10bits of resolution(0-1024), spread that across 0-50kpa versus 0-100kpa for example you would loose half your resolution. Ultimately its design decision also based on what level of vacuum you need to measure; for my application the one I picked was good.

    You would have to use a different sensor. They do have the "same" sensor with different ratings and several of them do positive pressures.

    Finding the port is a hard problem that is finiky based on how many comm port devices are attached.This is where the code starts, https://github.com/Makuna/Tbs4RpmWin/blob/master/Tbs4Rpm/MainWindow.xaml.cs#L291and it calls this to enumerate portshttps://github.com/Makuna/Tbs4RpmWin/blob/master/Tbs4Rpm/MainWindow.xaml.cs#L228and uses this to identify the port as being the TBShttps://github.com/Makuna/Tbs4RpmWin/blob/master/Tbs4Rpm/MainWindow.xaml.cs#L262You would have to debug the code to see why its skipping the port you have it on.

    Weller WES51 Soldering Station. I have had it for many years and they still sell the same model today.

    In the method private string FindPortName(List<string> portsSkip)you will see this lineif (portName.Length > 4) // skip COM5this is the problem. I had to add that due to have other USB devices that exposed a serial port that would choke if probed by the code in another place. This is suppressing all com ports that are single digit.

    In this [picture](https://www.instructables.com/file/F9K6S5XH2G5ZUVS) it shows the board layout, with labels showing connecting to the Arduino A0 - A3 directly.The board was designed as a shield, so it just plugs directly on the top of the Arduino.

    There is nothing specific in the code about the connection to computer. It treats it as a serial device. But I have never tested this configuration.The connection to the sensors also follows standard pin setup so it should work if plugged into any 5v Arduino.
