Ok I have been fighting a missfire/breakup for the past couple weeks. Car runs great besides this break up. It will do it while cruising and while under boost but id say its more while under boost. I Have a few datalogs of when its doing it and ill attatch them. When it happens my RPM signal goes away and either my voltage spikes to like 17-18 volts or it drops to like 3-4 volts. Ive cleaned all my grounds and my battery terminals. Also on 3 different occasians my Firmware has been erased. All my maps and settings, everytthing No damage to the ecu i just have to reflash everything.
My question is do you guys think my voltage regulator is going bad and causing the problem. Or do you guys think that my CAS is going out and causing my ms to mess up or something? IDK here are the data logs.
On the data log it did it on record 132,163,412,418,428,4399,4453,
