Question

I just installed a K&N GenII air intake and some Mopar Performance 7.5mm HP plug wires on my '99 Dakota 5.2L 4x4 Club Cab SLT. It also has a 3" Dynomax cat-back exhaust system I installed 6 mo. ago. My question is this: Will the computer adjust to these changes automatically? Or is there another step I need to take? I've heard about re-setting the computer after adding modifications but I'm not sure how necessary it is or the correct way to do it. Any help on this matter would be appreciated. Thanks.

K&N recommends re-setting the PCM. To do this, disconnect the negative battery cable and leave it off for 20 minutes. There is a condensor in the PCM which will store a little power, so it takes a few minutes.

I didn't reset after minor mods like plugs or wires, but for the TB, PCM ( obviously ), and intake I did. It takes a little time for the PCM to adjust. Most report several days.

dude,

thats very true what Fluid explained. take off the negative side of the battery. i don't know about 20 minutes though. maybe a coupl would do. then tighten it up. you might see a difference right away or you might not. either way after 40 or 30 miles the PCM will adjust to your mods. hope that helps.

MORE POWER TO DODGE
Thanks
Scotty
