Thanks it was all due an incorrect jumper. Rpm works fine.
So today i decided to setup my ignition system but i got a little confused about the going high and low.
Tunerstudio says the correct setting is usually the opposite of megasquirt and i use a 4 channel ignition trigger like the bosch 211. These modules need the setting inverted again? Or is this only depending by the transistors in the speeduino/megasquirt?
I guess the 4channel ignition controller ignites when no signal and charges the coil when it sees the 5v from speeduino? I had it set like this.
Anyway i had spark and the engine fired but fried the ignition control module when i tried to set the base timing. It got quite hot and now there is no spark anymore.
Speeduino signal looks fine so i think only the module is damaged but i how can i fix this problem. Maybe it’s the dwell timing in my tune?
I use a bosch 90492255 coil with about 3 ms dwell timing if I remember correctly.
