Ok, i just installed all the mods in my sig and took it down to a local tuner here. He says that my battery was low and he couldn't get into the stock ECU to tune it? Does this make sense? Is there some "secret code" to get into the ECU? Thanks.

 

How long was the car sitting. Just go for a spin or charge the battery and then try read from ECU.

 

heard this before i think its true never happened to me. if ur battery is going down then get a new one and retry.

 

Yea, he says he put a charger on it and still couldnt get in?

 

ur battery is probably gonna fail anytime change it,

some batteries get soo bad u cannot even charge them

 

Alright cool, just trying to get my tune done.. Any recommendations for batteries?

 

interstate battery is an awesome battery if you can find one.
They are green

Or you can go the mini battery route, and then you can rule a straighter upper intercooler pipe. xs-engineering sells a mini battery and holder as a kit.

 

Im going for a stock look, the mini battery just looks funny. I found an interstate near me and will pick one up there. More to come as i get my car tuned... hopefully, lol
