Getting the $0094 when trying to update firmware. Went back to the 8.4.82 version and it's fine. 8.4.84 did the same thing.

Hmm, that should have been fixed in this current release.
Can you save a *.htx trace file from the EFILive Control Panel after getting the $0094 error?
Send the trace file along with a support ticket here: https://service.efilive.com/new-ticket

Paul, can you take a look at why V8 doesn't allow changes to how the VE is represented for the E40 ecu's.

No matter what i change in the settings, it looks like the fuel map stays in Default units. Same file in 7.5 will show % theoretical maximum.

Forgot to add the VE "flags" to the E40 calibration definition.
I've attached updated E40 *.cam files.
Unzip them into the folder: \Program Files (x86)\EFILive\V8\Cam\E40 - overwrite existing files.
You may need Windows admin privileges to save files into that folder.

Half Sorted, might need to tickle the A0001 boost ve map too.

I've also encountered a bunch of module error crashes when changing controllers in the scanner when i change between dashes. Only way to get out, is to kill v8 exe processes completely.

I.e If i logged an e38 data file. I would clear the log, then try change to say ls1 or e40 dash & i'd get a module error with an ok button that wont go away.

Will post screenshot when it does it again.
