How to bypass electric power management .

[ToddB]

Hi I have a 2011 camaro and I installed a DC 270 amp alternator for my 2 amps. Problem is the computer controls the voltage that the alternator puts out. When I start the car and drive the first 10 min or so i get 14.3 volts then it drops to 12.3 to 12.5 for a while then it goes back up to 14.3 . It is so the car saves gas and shit like that. Anyone no of a way to keep the voltage up higher? I also have 3 XS power battery's in the trunk.Thanks

Might be possible to get a PCM tune and set the voltage different and gains some hps at the same time, not 100% on that though

That voids a 5 year 100000 mile warranty.

talk to mechman or dc (this first...since you got the alt from them)

edit: probably every option you do will void the warranty. im not 100% sure on this, but you will more than likely need to add a module in your car to bypass the pcm

Turn your driving lights on, see how that works out

This, if I turn on my headlights on my '09 Equinox, my charge voltage climbs back up to 13.9ish. Not the auto headlights either, but the actual headlight position on the selector switch.

Not low beams or anything, just the one before that

Blinker lights and tail lights- this one

Low beams and blinker lights and tail lights.

Try it on the parking lights and see, on mine it has to be the low beams as far as I've seen.

warranty is really important, see what you can come up with talk to the people who sold you the car check your warranty and all that good stuff, later on contact whomever sold you the alt and talk to them see what they can help you with.

I was going to post the exact same thing i have an 07 gmc yukon and the charging voltage is also regulated i think because it fluctuates from 12 to 14.

Is there a part that makes it a constant 14?
