Jeff, try RaceChrono. It's what I use, and I know you've commented that my refresh rate is a lot better than yours.

Can't thank the OP enough for the overlay! I use it constantly.

What do you use for obd port...i have obd link mx

The cheap-o blue one off Amazon Prime.

My refresh rate is very fast/near instantaneous. I use racechrono as well w/ a obdlink mx. I could be wrong here, but I think the faster refresh rates on one car vs another is due to the 06+ faster refresh rate vs. the previous years. Someone feel free to correct me if I'm wrong. The '06+ have a faster bus speed (I'm sure partly due to it being necessary for VSA) but perhaps it was just overdue.

FWIW, skatebrian is still rocking humbucker's overlay on his AP1, you just lose the last 1krpm of resolution. The refresh rate is much slower now on his ap1 compared to his old CR, which points to the pre-06 being the culprit for the slower refresh rates.

For the ap1 picture, I can work on that.

As far as sampling rates, I wonder how much is has to the OBD2 adapter you are using. I know many people use the cheapo versions instead of the recommended. Also, regardless of the adapter the serial bus on the older cars may only be capable of limited refresh rates. As stated above. If you reduce the channels does that improve the sampling rate?

Here's my setup:
QStarz 818XT
OBDLink LX (Not MX - I've heard the MX's sampling rate is slower from another user, but I haven't been able to verify this)
RaceChrono
RaceRender3

Works perfectly, but there are a few important things to note:
-I've heard the cheapo OBD readers have major QC issues - that's why I splurged on the OBDLink LX
-before uploading your data file to RaceRender, delete the GPS speed column - RaceRender defaults to reading your GPS data first before your OBD data, but I've found the OBD data for speed to be much more accurate

The link to my metric template is old. If others would like it, I can post it again. Here's what it looks like: https://www.youtube....h?v=DbJNo5CaIlM

It does and also i use the obdlink mx. Ill try the racechrono sat

Will this work?



Maybe this, but the flash washed it out.

Thanks Apex. I gave it a quick stab, but I don't have time to actually test any video out. If you don't mind trying it out and let me know if needs any tweaks...there's a chance it could be really wacky

I actually don't have race render. Can someone else give it a shot?
