1.1.27 works well I can make spark everywhere :)
Q. : The pulse width always 1.6ms or less ( with firmware 1.1.27 ). The used config is the same with 1.1.23. (with 1.1.23 and the same config and tables I get the right pulse width -around 15-20 ms for crank -). What could be wrong?
A : Did you update the vemsv3.ini in your current Megatune directory to version supplied with the firmware distribution e.g. in \firmware_1.1.27\doc\megatune\vemsv3.ini ? Pulsewidth variable was changed a bit in 1.1.27 (higher resolution). - DB
- I was my fault, problem solved. THX

The engine is runing. Both VR sensor needed 15kOhm pullup.
Q.:Problems with spark advance -tested between 800-1200rpm- . Engine runing, LCD (Megatune too) shows the right advance angle, but I get spark around the rigtht (plus-minus 5-10 degree). I tried with signalgen too .
Scope1: crank signal(stimulated with signalgen around 1000rpm) with one of the ignition channels.
Those pins looks not too good for me
Scope2: two ignition channel together -EC36pin34 EC36pin36- (stimulated with signalgen around 1000rpm)easy to see the difference between the pulldowns
