Just kill that VCM.Just learned of the j35 bank one issue for the 2012 and possibly newer ones too that may have piston ring issues. Just did new plugs at 116k. All were good except 1, and 2 were a little dirty but not trashed. Should I be concerned? Runs like a top. Thanks
Most definitely could be the VCM taking you down to running on 3 or 4 cylinders.Also from other posts I’ve read about vcm there may be a shudder. I feel a vibration but it feels like a wheel balance issue. Is that what the vibration of vcm could be making?
It's the warning of a over heat problem that may concern me since its reading 30° lower than it really is. It can not be the cause. I just check my temp more often. Other things usually start happening before warning light comes on anyway.What are the chances of overheating the engine with vcm delete?
My scan tool reads 166°.How do u check your temp? Scan tool? What do u think about the high speed vib? Vcm or no. Either way I think I’m gonna get thesvcm for peace of mind
If your engine temp reaches op temp, when your eco light comes on the VCM is active.FYI just drove it around from cold. No discernible difference from vcm on and off. Watched for eco light and cannot feel when it kicks in or out. Regardless I ordered svcm. I figure do it now before I feel it. Thanks. Also I know this is not the post for it but y’all know the crush washer sizes for the rear diff, transfer case and tranny? Thanks
The car won't overheat because of the delete, but it may make you blind to the car overheating from other causes. The VCM Muzzler will give you a false reading on the dash and potentially well into an overheat situation - meaning you may overheat and not know about it. The S-VCM and the VCM Tuner II both are smarter and will turn off if the car actually starts to overheat meaning you'll KNOW if there is a problem. Because of this - I'd only do the S-VCM or the VCM Tuner II. I have the S-VCM and have zero complaints with it.What are the chances of overheating the engine with vcm delete? Also will that give a false temp reading on the dash? And I still have the vibration on the highway going 80, which is outside the 40-60 mph. Thanks! I don’t mean to be a bother.
I have the VC Muzzler on my 12 for about 15K miles, not a hiccup one. The only thing that has happened in heavy traffic(i.e. 4th of July at The Indiana Dunes National Park), the Eco light came on once or twice but once I started moving continuously it shuts back off.Used the VCM muzzler on mine. Had to switch out to a different resistor (supplied with the kit and instructions). Was in an extended conversation with a friend while it idled last week. Cooling fans cycled on and off repeatedly. No overheating.
