Converting from resistance to voltage

Forgive what is, I'm sure, a dumb question. I'm switching to a Bosch oil temperature sensor. The datasheet gives calibration information in ohms: http://www.bosch-motorsport.de/content/downloads/Raceparts/Resources/pdf/Data%20sheet_ID0EQ3EZ.pdf But clearly I need to configure my RaceCapture in volts...

Hi Paul, Still seeing crashing problem with the latest firmware? (2.9.2) Sorry Brent - I should have reported back ages ago. No, I'm not seeing the crashing problem any longer, but I can't be certain that the new firmware was the fix. We suspected an installation problem, so at the same time as upd...

Will do, Brent - FYI we're going to be testing the car on Friday 10th.

Thanks!

First off... that is a BEAUTIFUL looking Lua script. As a fellow programmer... thank you for doing it right and well. Thanks - one of the downsides of providing an embedded programming language for this kind of thing is that you're going to get a lot of scripts written by non-programmers. Pleased t...

I've attached my configuration to this post. I don't see it. Damn! Sorry about that - it looks like the forum software throws away an attachment when you click the Preview button :-( I'm traveling at the moment and won't have access to the file until Friday - I'll upload it then. The issue I mentio...

Thanks for the reply, Andrew - much appreciated. I've attached my configuration to this post. I am (as you will be able to see from the uploaded configuration) starting logging via Lua. I doubt that this is the problem as the problem first appeared on Friday when I was running exactly the same (very...

On the plus side, even though I was racing without a dash or shift lights for most of the time, and deliberately ignoring the big red "your engine is about to destroy itself" warning light, I came P2 in race 1 and P3 in race 2 ;-)

RCP continually crashing :-(

I have an RCP that I ran all last year with no problems. It also ran fine in the first race of this year, but suddenly it's started repeatedly crashing :-( I would appreciate advice on how to diagnose the cause of the crashes. Here's a detailed description of what I'm seeing and what I've tried so f...

Here's a capture at 5MHz instead of 625KHz. There's clearly quite a bit of noise around zero, but all seems to be below 1V. Given that the setup is working, I guess the RCP2 is filtering it out?

Thanks, Paul for the update! What is connected to each of those channel inputs, just to be clear There's only one channel input—it's the tacho output from the ECU. The top trace is in the digital domain, the bottom trace in the analog domain. There are some strange artefacts in the digital domain, ...

Multiplexed ShiftX lights

This weekend I've been testing a script which multiplexes the ShiftX so that it operates as both shift lights and an error light. If there's an error condition (temperature too high or oil pressure too low), only the central red light is illuminated. If there's no error condition, it operates as shi...

A scope would be super handy to see exactly the pulse rate at a given RPM. Mystery solved—I got a scope on it, and the output was a perfect square wave, one pulse per rev. I've attached the output from the engine while it's idling at around 1200rpm (which gives 20 pulses per second, exactly as you ...
