Brent, That's exactly what I did. It took me a bit of time to figure out how the analog gauges work but I found a schematic someplace that made it clear. For the analog temperature gauges there are two wound coils inside the gauge that act as electromagnets to deflect the needle but basically appear...

Howdy, Brent helped me debug an issue getting my MK3 connected via cellular and I wanted to post it on here for reference in case anyone experiences the same issue. After installing my SIM card, setting up RaceCapture and powering up my unit via USB I would not connect and kept seeing the following ...

Brent,

I've got it figured out I think. It's actually pretty cool and i am pretty sure I know how to piggyback my gauges. If I get organized I'll write it up.

Thanks!

Dave

Brent, Sorry to be needy. My weak electrical engineering skilz are showing through. I'm wondering if the work I did characterizing the sensor resistance as a function of temp isn't going to help because i need it to continue to function inside the circuit with the existing analog gauge. I was assumi...

Sorry.. A bit more information. I feel like I'm pulling the thread on a sweater here. I checked the output sensor terminal on the analogue gauge without a sensor attached and its 5V. However when I hook up the sensor, the voltage jumps up. With the sensor at 220 degrees the voltage is is at 8.14 vol...

Brent, Thanks for your note. Very helpful. I have just finished characterizing our temp sensors using an inductive hotplate and a hot oil bath. I have a thermcouple I used to measure temp. I did a curve-fit and have equations for resistance as a function of temperature. The (good) news is that I che...

Hmmm... a bit more information and another question. We just noticed the statement on the web site that Low resistance gauge type sensors are not recommended. Which is the type of sensors we have. Cany anyone expand on what's meant by "not recommended"? Is that "not recommended" ...

if I put it on 1 it shows 660 at idle, the engine idles at 1300. At the limiter 6500 it shows 2700rom. Everytime I go up it splits the number in half. Just pointing out that 2700 isn't 1/2 of 6500 right? Might have been a typo but i thought I'd point it out in case you're waiting for a fix that's n...

Howdy, Chumps endurance race team running a 1996 Dodge Neon. We've ordered Racecapture Pro and are excited to hear it's on its way. First race in is a month so we've got some work to do and will certainly need some help from this forum. A few introductory questions. The Neon is pre-OBDII so that's n...
