I'm having the same problem on my 2019 Toyota Camry it's got the smart charging system keeping my voltage at 13.8 steady even with subs amp lights ac etc. I have upgraded literally everything except the alternator and the only reason I haven't done that is because several major alternator companies have told me unless I figure out how to do this and bypass the ECU controlled charging system that no matter what size alternator i use it is going to recognize it as stock and charge at the same voltage im wondering if you can please help me start the process of figuring out what steps of this that I need to charge my lifepo4 and agm batteries any advice would be greatly appreciated
I don't know, but I wouldn't be surprised. Get one of those cigarette lighter adapters that also has a voltage gauge in it and watch your voltage as you drive around. If it drops below 13V with very little load while you are at highway speed, you probably have VVCS crippling your alternator.
Hey great info....
But can you show me how used, the Torque lite app to
correct ecu in your 2015 QX60 Sir.
Thanks
Great video..... Thanks for the information and keep on representing Space City and its miserable weather, ...

Does a 2010 FX 35 have a VVCs?
