I have a complete Powerbox system, Pioneer, PBR-26D, igyro SAT, GPS III and a SparkSwitch PRO in a GP38 gas engine.
Telemetry on Core display from sensors Sparkswitch pro RPM, Voltage, Current is not stable, it flashes between 0 and whatever speed the engine is running and voltage from 8 to 0 volt, look at log file picture. When engine is stopped the Sparkswitch pro voltage has a stable curve on log file, when engine running its a mess. You can lay these two curves on top of each other and trouble is only when engine is running on the Sparkswitch pro voltage and Current.
Temp sensor readout is stable.. Capasity not so bad as Voltage.
I tried everything (hopefull not) so far, removed temp sensor, remover choke servo, removed LED cabel, moved ignition battery everywhere. No cabels are crossing each other, seperated dirty side and clean receiver side as pictures shows. Tagged all cabel on attached pictures to easy see this.
Any chance the ignition module is too close to the throttle servo??
