I'm having big issue with noise on the 12v of the car.
I installed a ms1extra last year. Everything was working fine. Then this winter, the owner of the car rebuilted the engine.
running ms1 with low impedance injectors with a resistor pack
3x MSD twin towers coil pack drive by original igniter.
After the rebuild, the guy was having troubles with hard cuts on with the ms. There is so much noise that the ecu reset everytime he hit boost and fews times at idle...
I double checked all grounds and everything is like before. I'm already using a capacitor on the igniter.
I can add a capacitor to the MS but this wont solve my problem... I will try to add a capacitor near the twin towers coils pack.
But I still dont understand why is was running well last year.
This is what it look like at 1000 rpm. Noise increase with rpm
