Struggling to get this downloaded and installed right.  Downloaded the fully functional version off the github.  But cant seem to find out how to get it installed.    THe .msi installs the 1.9.4.3 version of the flasher, but still cant see any fast write part of it.

"fast" is actually "diff write"

Thats what I normally use when flashing.  Normally takes in region of 4mins 30seconds.

Thought you could get it much quicker than that?

The less you modify the less it will have to write. Also you can try increasing baud rate.

even a 1x1 KRKTE byte will take the same amount of time Sad  Normally have 10400 baud rate with a VCDS lead

That's about as fast as it will go, since even a single byte change alters quite a few checksums.

Also, because of the way flash works, changing a single byte requires erasing and rewriting an entire flash sector.

It shouldn't take 4 minutes 30.  Single/small changes typically take ~1 minute for me.

Sure, it's open source.

In its current form, no. It's hard-coded to use FTD2XX and the FTDI driver DLLs. OpenPort 2.0 is J2534.

Hi!

What could be a problem with my car if I cannot read the flash with max baudrate? Only the lowest speed is working. With other baudrates it fails around 15%. I havent tried the write because of the reading issues.

You may need a dedicated k-line or pull the cluster fuse. Also try bench reading it if you dont have immo.
