Will disconnecting the battery for a prolonged period of time effect the new timing parameters? Or is it there pretty much forever?

 

anyone?

 

I don't know if anyone has tested it yet.

It seems like an eeprom change in which case it would survive a long term battery disconnect.

If it's not an eeprom then all bets are off but most people feel its an eeprom write.

turbo dreams
woosh

 

sounds good, anyone else? reason i ask is that i just got mine advanced but then accidentally left the batter d/c for a few hours while messing with the intake

Don't worry about a few hours. The ECM has a battery backup that lasts at least 24 hours (for 2K2 and later).

 

thats reassuring, thanx
