I just installed my midpipe and was curious as to if I needed do anything other that kill the airpump?? I'm not ready to take the AP off just yet, so can I just unplug it so the clutch won't engage or will that screw w/ the computer?? I do have a PFC (should I reset the PFC and relearn for MP?)and the following mods already are installed:
STREET PORT (MILD)
HYBRID SEQUENTIAL (PETTIT)
STOCK MOUNT IC (GREDDY)
DOWNPIPE (GREDDY)
CAT BACK (N1)
INTAKE (APEXI)
PFC W/COMMANDER
now:RESONATED MP (PETTIT)

any suggestions are appreciated. Thx.

 

i don't think that the power FC will "learn" that you have a midpipe. and if you reset it, i think it goes back to the base map. i think that you'll have to tune your Power FC for the midpipe.

 

i think if you are not going to remove the air pump yet you should just leave the harness plugged in and just leave the hose under the car next to the mp hanging there. if you unplug it but leave the belt in place, i would think it would place extra stress on your other auxillary components.

and the power fc doesnt learn anything unless you type something in. im pretty sure there are plenty of maps you can enter in the pfc specific section in the forum.

 

I guess I'll just go buy a pulley set and head off to the dyno,,hehe.. I had it tuned as close as possible from the maps on the forum, so I should be fine till dyno time. Now, once I remove the AP is there anything else that needs to be done?? Plug any hoses, block off anything, etc.??

 

The Airpump is clutch driven. Go ahead an just unplug it. It will just free wheel. Also The air pump provides secondary air injection into the manifold under light throttle so you will see a loss of low end response and a richer mixture.
