What's available for this varies widely between different cars, so that's why we don't have it selected by default.Presently, there is not a boost video overlay within the app, so you would need to use RaceRender to show it on a video. The best way to overcome this is to change the OBD channel selection to one of the Throttle Pedal options, assuming that your vehicle offers this. the engine computer is using your throttle pedal input to determine how much engine torque output it thinks you want, applying various other adjustments to that, and then commanding the engine controls accordingly. This was simpler with the old cable throttles that were a direct relationship to your throttle pedal input, but in many modern vehicles, it can have a mind of its own. The first speed in the list will be GPS, and the second will be OBD.Īssuming the OBD-II adapter and vehicle ECU are reporting properly, this is likely the actual throttle plate position, rather than your throttle pedal input. In RaceRender, it should default to the OBD speed (tends to be better for detecting gearing), but you can switch between the two by double-clicking on the data file in the "Input Files" list, going down to the "Vehicle Speed" selection, and choosing a specific data field. In TrackAddict, most everything will be based on GPS speeds, although its in-app video player can be switched to show the OBD speed instead. GPS speeds can jump around like that if there's poor signal conditions (in which case your driving line data might look a bit rough too), and OBD speeds may do similar if there's communication or compatibility issues with the OBD-II adapter or vehicle. Any ideas what might be happening there? Not a super big issue since it works in RaceRender.This is most likely a difference between the OBD and GPS reported speeds, with one app using one and the other app using the other. I thought it might be because I do have one of the generic $15 OBDII adapters, however, if I export that video to my PC and watch in RaceRender, it's spot on. ![]() It has me doing 5-6mph when I'm doing 30-40, and then goes the other way as well, sometimes showing 60-70mph when I'm only doing 50. When viewing the videos in TrackAddict on my phone, the OBD speed is WAY off. In TrackAddict, I can Gear+1 to accurately reflect the gear my car is in, but when in RaceRender, I can't quite figure out how to do that. One last thing, I'm sure this is in the documentation somewhere, but I haven't been able to dig it up yet. When I finally hit WOT coming out of a turn, it jumps up, but then settles back down to about 50%, even if I'm on the long straight where it's 100% floored for quite a bit. The other thing I've noticed is that my throttle indication, even if I select percentage, it doesn't accurately reflect the current throttle position. Any ideas what might be happening there? Not a super big issue since it works in RaceRender. ![]() The first thing, and the one that prompted an account to ask: I recorded my first outing but I am experiencing some strange behavior. Just started attending track events in my Focus RS.
