[Trigger] [Config and tables ] [Q & A]

2007-09-09

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

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 or more). 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, but disappear without the wastedspark coil.

Scope2: two ignition channel together -EC36pin34 EC36pin36- (stimulated with signalgen around 1000rpm)easy to see the difference between the pulldowns

Az elogyújtás értéke a fent látható módon változik a dwell értékével együtt (scope2). Igazából nem sikerült a kiváltó okot megtalálni.

Ugyanazzal a (Signalgen által produkált) wav-val hajtva véletlenszeruen:
