know that for a fact :)

vince sends mace tunes as far as I know for mail order type scenario...

where as dale tunes them himself and only needs vince when a new os is found

First name basis says it all really lol. ;) So they kinda help each other out so they both benefit.

Yeah, Grunt the only way to remove the "BUFFER FULL" error is to go purchase a "OBDLink" from the scantool.net bunch since thats a MASSVE upgrade in terms of buffer size, processing speed ect.
Also, in the next version, ill add a filter.. so the elm will only pick up frames we want.. but, we need to know which devices are what responses so that we can focus on there responses!
Once we do that, less information will be sent over to the computer.. stopping that annoying buffer full message!

Make sure you run the cable at 115200 baud too. This will stop alot of buffer full messages. I've found this with CAN as the network is sending data at a very fast rate but the connection to the PC is too slow so the cable has to buffer it.

No worries, I think Ill just have to set that as default preference. And whenever anyone changes to something else, will just save as new preference.

My ELM won't connect to pc at anything other than 38400, would be great to have it at 115200!

You have to set it to do it in the PP settings mate. Page 63 of the ELM327 manual

Instead of using the PP settings since that permanent, Iv gone with using ATBRD, which is just a temporary baud set and will reset on next power up.

So, the 38400 baud (or whatever the elm current responds back to) needs to be selected first off. App will then verify the elm cable is there, next it will then request for the faster baud rate (115200), waits for the em to respond with 'OK', then app will switch to new baud and then waits for the elms response of "ELM327" to verify the new baud is working.

Hopefully the code Iv implemented works. Frustrating to not have a cable let alone a car or bench setup to test on.

Awesome work!!!!
Perfect & not 1 buffer full message yet!

;) J1850VPW is just 41.6kB/s

HSCAN though at 500kB/sec is where you will see dramas without filters
