Hi kbuckham, Thank you for the note. We will investigate on our end and make a note as necessary. Can you try to connect the switch so that it switches the 5v reference from RCP into the analog input instead? Also, you can also set the GPIO in input mode and connect it that way as well, saving an i...

Weirdness With 12V Connected To Analog Input

While I do understand that the analog inputs are only useful from 0-5V, I understood they were safe to use voltages higher than that. I was using a switch on my dash that activates my methanol injection system and to kick off the RCP logging on Analog input 5. As soon as this input goes high, all th...

Yes, please! That was fast! I just ordered two of the op-amps yesterday, but your circuit is much nicer than mine was going to be.

Thanks, I'd love to say it was my idea but this is where I stole if from: http://www.dsmlink.com/wiki/ecuinputdata

The 15.1K ohm input impedance is considered low by the ECM vendor so I'll be testing all of the inputs. I think I'll build up some buffer circuits for the inputs using a TLV2375IN (http://ca.mouser.com/ProductDetail/Texas-Instruments/TLV2375INE4/?qs=sGAEpiMZZMtCHixnSjNA6Dh9CQmOfcFcb933fWMBL0g%3d) as...

Safe To Use ECU Connected Analog Sensors?

I have several sensors connected to my car's ECU like MAP (manifold pressure), TPS (throttle position), AIT (manifold air temperature) that I would like to connect to Race Capture Pro. The ECU already supplies a 5V sensor reference line that all of these sensors use and of course these sensors are n...

Perfect! Is there a way I can get started on building something soon or will that be after the general release? I'm not looking for special access, I'm just curious.

Logging Serial Data

How easy would it be for us to log data from a serial input? I am in the process of getting my engine computer to spit out it's real time logging into serial data. I would really like to log the Race Capture Pro and engine computer data once and ideally in Race Capture Pro. How easy would this be to...
