Rob Humphris - Cambridge, UK.
From a VEMS user:
"My LCD seems to have taken a s**t. It works fine for about 5 mins then the screen changes to loads of weird characters and jibberish. I turn off the car and restart and it works for 5 mins again, then does the same..."
He's running Version 1.0.23
Today the problem seems to have stopped, which is in its self rather worrying.

The closing times are also needed (it is the function of injector current and flyback voltage). The flyback voltage actually makes a huge difference.
The opening times are not (by far) enough to calculate GenBoard/Manual/Config/InjectorOpening parameters. You can start from other's values, make sure
- injopen=00 (or very very short for low-voltage flyback, max 100 usec)
- battfac=10 (256..700 usec is usually OK)
- injocfuel=2C (500..1200 usec usually)
- injrampup_battfac=FF (IIRC 4082 ... in MegaTune, it does not have a simple physical unit like "usec" or similar)
