OK i have my motor trans in my iroc r/t, its not running and drive as of right now BUT it will be tonight i hope. but anyways, I plugged my battery in last night and my overhead consoule said -70 on it. I can't remeber if it was like that the last time i had the motor out when i upgraded things. and also my abs light comes on after about 30 40 seconds of the key being turned on. It also makes a grrrrrr noise from under the battery. I know when i first was driving it it worked fine, after i put my stage 4 cal and all the goodies is when my abs started doin this. Could my cal be making my abs and overhead consule read all gooffy? Any help would be great!!!. I hate things not working propperly.
