Hey all- Just ordered a PowerCommander 5 + the autotune module. Im looking for any advice with the install on my 08 vegas.
I've reviewed the PVC instructions and it seems straight forwards, I figured it would be wise to start a compiled guide and track some things to assist myself and the all the users here.
My initial thoughts are:
- Prior to install update firmware on PCV and load a close base map thats fits my mods. I'll check the maps that come with it as they seem to be expanded from the downloadable ones on PC website.
- Mounting the PCV, Insure the USB port is easily accessible, possibly different from whats suggested by the manufacture.
- PCV Fuel injector Harness- Hardest to remove, Some people suggest using a butter knife or needle nose plyers to assist
-Autotune 02 sensors, insure to use anti-seize when installing these and be careful to not strip the old Narrow Band sensors when uninstalling.
-Auto Tune Power, I have a mini-fuse inline fusebox tap, I plan to tap into the switched accessories fuse circuit inside the fuse box. A self tapping screw can be used for the ground or the neg battery terminal
3. Tuning notes (Gathered from multiple site)
-If deceleration backfiring occurs after loading base maps and tuning-
"Try zeroing out your 0% and 2% columns, both in the AFR table and the main fuel table, then just set your idle AFR to 13.2 (0% at 750-1250rpm) only. I think the Autotune tries to lean out the 0% and 2% columns too much because most of the time spent there is decelerating."
Thanks in advance
