I'm gonna guess it's from the cold air intake.

But what do you mean v6 SS?

The battery back-up isn't a battery perse' but it's to make sure the ECU, TCU, BCU etc.... doesn't lose power.

What do YOU mean v6 SS. I own a 2SS/RS. A V8 here.

Good catch tran!

MMMMMMMMM,,,, Makes me still wonder why then if you SAY, ADD a CAI and they say -----to disconnect battery !! not pull fuses to reset.... So where then is this battery between ecm and battery in trunk ???? [in ecm ????] ... Guess i would have to do some wiring diagram study to see this and figure out ????..

Referring to this. I guess a typo.

[JEFF75645]

So are you saying i wasted 30 seconds of my life pulling those fuses by not disconnecting the battery cable also.

I think the phrase v6 powered SS is their way of saying I have a v8 and it feels like a v6. Or at least that's the way I interpreted it

[JEFF75645]

Oh. That makes sense. Learn something new everyday here. Thanks

Exactly what I gathered too

[carls2010]

yes ,,if fuse pull is the correct fix, and battery disconnect doe'snt fix.. Well i guess i would have to look at wiring diag and ecm, as, im looking at it as, --Fuse pull removes voltage to ecm, and after enough time resets ecm.. well disconnecting batery removes voltage to ? and would take fuse away like its not there.-- Hope im explaining what i mean guy' ok... thanks

Crap. I you are right. I guess my sarcasm meter needs fixing.

When I had my car on the dyno and we disconected the battery there was zero change in pulls. It was only after we did the fuses a few weeks later that the change was noticed.

I'm a little slow sometimes.

I know what you are saying. And the GM engineers explained to Scott that the battery won't effect the ECM unless it's left unplugged for days. The battery back-up must just be a item to hold juice for a short period of time un case of a dead battery or something. I've not seen the wiring diagram so I'm not sure but my dyno sheets showed me that the battery pull didn't reset the ECM on my car. Only the fuse pull did.

In fact I suspect that it's not necessary to leave the fuses out for hours. I'd bet you should be able to pull them wait a minute and put them back in.

I broke this open with my vids and dyno runs. I left them out for about 3 hours but not intentionally. Just got busy around the yard and I didn't think the fuses would do anything since NOTHING I tried had worked to that point.

mmmmmmmmm,, still sound's funny... But i was pulling fuse's over nite, and then after that know diff in veh...... AND car felt like a v6 powered veh.. lacked alot of pull after it hit 2200 rpm... So i went ahead and disconected battery for 5 min. hooked it up and took for ride. WOW Major diff ,,pull,power,, like car was suppose to have... - Can only say it worked for me and fuse pull didnt ??
VERY VERY INTERESTING..

I'm going to find the schematics for the system. If yours is an LS3 car then it would make sense that both is required. It is said that the LS3 requires the battery too.

[carls2010]

Yes mine is the LS3... PERFECT EXAMPLE OF SOMETIMES NEW THREAD [POST] NEED TO GET RESTARTED TO KEEP UP TO DATE.. Sorry for cap on,,lol

Well the LS3 was reported early on that it needs a battery disconnect but I can't find a schematic for the 2010 Camaro.

It's not the battery part that makes no sense to me it's the fact that you cut power to your ECM (which is essentially is what pulling the battery does) by pulling the fuses and said it didn't make a difference. And then unplugged the battery and it did the trick.

The part that doesn't make sense is that you cut power to the ECM and it did nothing. Pulling the fuses cuts ALL power to the ECM. You'd have to have two power sources to your ecm both fed directly from your battery.
