diconnecting battery after tune
If I tune my car, then I have to disconnect the battery? Does this have to be don at the battery? Or, does disconnecting this jump post under the hood perform the same function? Thanks.

disconnecting the jump post won't do it... that's just a remote jumper cable location - power will still be going through everything because the battery is connected...
you need to do it at the battery itself... |

Tune doesn't affect how you would handle a battery disconnect. If you disconnect the battery the only thing you will have to mess with is the window indexing, and there is directions in the owners manual on how to reset that easy.
To disconnect any car battery - do it at the battery, negative cable first. Then when reconnecting - negative cable last. |

When BOTH positive and negative cables are OFF of the battery, touch the two cables together a couple times to down power the keep alive feature in the ECM.

Yeah, I disconnected my battery and it had no affect on my tune. But yes, my windows had a little trouble indexing. But that corrected itself. |

If you decide to go the tuned route, SCT's programmer will reset the trims/learning for you. No need to disconnect the battery or ecu. Which in my experience does not immediately clear anything. I've disconnected it, logged the car and still saw the same learned values. After using the SCT I don't have to worry about any of this.

Intersering, how did the 2.5 bar tuning go. What sensor you use?

Is it safer to disconnect the battery? Wondered if unplugging the ecm runs any risk of a voltage spike. It would be more convienent to just unplug the ecm.
