Need Help With A Few OBD 'Quirks' and HLT

[jmciver]

My question has been if the VIN of your Ford is part of the Ford's vehicle definition already. In this case, LT will certainly not ask again.

It might be, but since the VIN was not automatically added to the vehicle description field (like it was for the first car that I added to HLT) I have no way of knowing. I will try deleting the Ford and create a new vehicle, which may "reset" HLT to query for the VIN from the vehicle.

Just select Vehicle List and the Ford afterwards. The VIN is displayed in the Vehicle Details (if set).

The VIN was never "defined" for the Ford as you are describing in the Vehicle Details section. But it was defined for the BMW X3, which was the first vehicle I added the last time I uninstalled/reinstalled HLT. During my troubleshooting, I deleted that vehicle profile in an attempt to get the VIN for the Ford vehicle profile without any good results.

Just before I made this post, I deleted the Ford vehicle profile and created a new "Unspecified" profile. I then connected HLT to the Ford and the popup window asking me to link the VIN appeared. I said yes, and then I got the second popup window asking which vehicle I wanted to link the VIN with. I linked it with the new "Unspecified" vehicle profile and it worked (the "Unspecified" profile no has a VIN defined to it). Of note, I did not use the Unspecified profile that is always in the vehicle list, I created a new one. I am guessing that HLT may have already associated a VIN with the Ford vehicle profile, which is why the VIN link popup window never appeared. But for some reason, the VIN was never added to the Vehicle Details section.

I will test this same procedure again on my BMW X3 (the profile which previously had a defined VIN but I deleted during troubleshooting) to see if I get similar results.

Can you please select any vehicle, press Export, select All and send the result to me (Harry@gps-laptimer.de)?

Sure, I can do that. But before I do, I just successfully added a second VIN to another vehicle (my BMW X3) and here is what I did (very similar to how I did the Ford):

1. I created a new vehicle profile called "Unspecified (1)" by default. The car was not running nor was HLT connected to the car.

2. I changed the description from "Unspecified (1)" to "BMW X3"

3. I went to the car, started it and connected HLT to the car via my OBDII Bluetooth adapter.

4. I was asked if I wanted to link the VIN and to which vehicle. Upon which I selected BMW X3

5. The BMW X3 now has a defined VIN in the Details section of the Vehicle Profile.

Once the VIN was defined I added the rest of the specific data (HP, TQ, etc) for the BMW X3. Did you still want me to send you that file (either the BMW X3 or Ford Expedition)?

Well, I don't know how to explain this. I used HLT with my eBay Bluetooth OBD II interface at the track for the first time today. Based on initial testing before going to the track, the throttle response with my BMW M3 was very choppy if not non-existent. RPM response was adequate, but not great either, at least when compared to the testing I did with my Ford Expedition where the RPM and throttle response was pretty much instantaneous.

I recorded two track sessions (30 min each) and during each session the throttle response displayed in the video was smooth like it should be. RPM response in the video was better as well. My only explanation is that the CAN bus in the BMW updates the data quicker when the engine is loaded. But I have no real way of knowing for sure of course. I am just happy that everything appears to be working the way it should with my hardware and car.

Reason is a different one.

While driving, LT gives you a kind of preview of the later video - but displays data in real time. As the BMW delivers throttle very slow, the display is choppy and all other PIDs are slow too (because they are slowed down by the TPS request). LT v16 will allow selecting alternative throttle PIDs for BMWs.

The reason the display is smooth in the overlaid video is LT uses data interpolation excessively here. Even with pretty bad data, the videos often look very nice
