VY V6 Flashed ECU runs great until VATS Light starts flashing

Post by rossi1959 »

Hi Guys & Gals, As in the subject heading the issue is that randomly the VATS light on the dash starts flashing and the engine gets a bad miss which feels more like a very quick total engine shutdown and restart and then sometimes total shutdown. If I remove the ground cable over night the issue is gone until the next time the VATS light starts flashing again. I have "The1's" Enhanced tune which already has the VATS removed and runs and shifts great except when the VATS light rears it's head. Any pointers would be appreciated. I have checked all the grounds and installed a new CAS.
Cheers.
Rossi.

Do you mean VATS or CEL? If CEL, try reading the codes to see what the logged fault is.

My VY will randomly run with security light flashing but i dont get any running issues can you post a vid of the light amd it running bad. A log would be awesome if you have a lead and software to plug in
