Racerender sync tool1/8/2024 Sorry for the long post, and sorry if this has already been posted. The GPS accuracy is not down to the inch so it's difficult to analyze the different lines one drives but it's cool to look at none-the-less. For fun, I have tried exporting in KML format to put in Google Earth. CSV format which I've been watching my test trial data run through. The video overlay software also uses the. There are other formats listed along with compatible software in the instruction manual. I'm not sure how this works on other data acquisition devices, but this is the only limitation I have found with this system.įor exporting data, I've been using the CSV format as it works with Excel. I quote, "Most ECUs run at 3-4Hz" with this software. Upon further research, it turns out that this is a hardware limitation of the car's ECU itself (E36 M3). Engine speed seemed consistent but it's also first on the list of channels (Data points) to record not sure if there's a relation between that. Upon reviewing my test trial data, I noticed the "choppy-ness" in RPM and throttle position. I was logging RPM, speed, and throttle position. Vaguely put, that's 3 data points a second. The data acquisitions from the scanner are only at 3Hz. Here's where I thought I lost the gamble on being cheap. With the new receiver, these random spikes are almost non-existent and very minute. There was some random movement, expecially when sitting still. It was pretty impressive and worked out nicely for a 'stock' GPS antenna. The phone is a Sprint HTC Touch Pro 2 and the other harware is what I linked in the description above.įirst, before all the extra hardware came in, I tried the app out with the phones GPS. To add, my phone is all kinds of hacked so I was kind of surprised everything went smoothly and is running great on the phone.Įxcuse the mirror screen protector on the phone, it sounded cooler before I bought it. Or, a premium software like RaceRender 2:įirst off, this worked out nicely for me since I had an old Windows phone laying around. There is software out there to lay the logged data over video. I took a gamble on buying a generic, 'Made in China' one as the software developer advises to use the rich-man's device that the software was developed with. I had no idea Bluetooth OBD-II scanners existed until now. Plus this one has a lot of good feedback from around the web. Here's the one I bought there are cheaper one's out there but not by much. In my case, I purchased a 10Hz receiver, meaning it will log the GPS coordinates at a rate of ten times per second. Well, the answer is a Bluetooth GPS Receiver. Compatibility includes Android phones (still being developed) and older Windows phones and a few others.Īlright, so you might be saying that a cell phone GPS antenna is insufficient. There's an instruction manual to explain the basics too. The app for the phone is kind of a no brainer. (It also has the ability to log OBD-II data as well.) Racechrono is a GPS lap timing system for Windows phones and Windows computers. It was kind of hard finding answers to questions about the software/hardware so here's what I have found out/learned so far. It may or may not be 'new' news, not sure. Hey folks, I just wanted to share this with you guys.
