Thread: help me to understand

okay, so forgive me for being ignorant, but i would just like to understand this whole concept on pcm's. i have a few ?'s that i would like answered that i can't seem to find threads on...

#1 - is it worth getting a tuned pcm on a N/A car?
#2 - if it is, should i get one with my only mod being a custom FWI?
#3 - can they be retuned as you upgrade/add mods? (i have heard that some cannot be retuned)

thanks for any help with this. pardon my noob-ness, i just really want to understand this stuff before i get neck deep in it...

ahh i dont remember his screen name. 99prix??? he has a gt with an overkill pcm. said it woke his car up, better shifting and what not.

most pcms are not locked, if they are, like overkill, you can send it back to him for a retune.

yes
yes
yes

it will help with a bunch of problems the n/a cars have and make it more fun to drive.

just remembered another ?, do i have to get one year specific to my car, because overkill only goes up to an 05 GT, and i don't have a GT, does that matter?

they droped the name and badges after 05+ they dont have tunning software for the 06+ so he will have to send you one from an 05, they all will. sometimes the gas reads the oposite way. he might have it worked out now

I doubt there's anything he can do. I believe that at some point the internals of the fuel level sender were changed. The readings off the potentiometer were reversed, for whatever reason. I do believe that if someone who's fuel gauge is reading backwards would swap to a 04-05 GP fuel level sensor it would correct itself.

Edit: After checking Rock Auto, the part number for the fuel level sensor in GPs changed from 06 to 07.

no way to set the gauge to read backwards?? im not much of a tuning person.

i'm confused, so if i get one from will (or anyone for that matter), my gas gauge is going to be backwards? thanks for responding though, i emailed will about this 3 or 4 days ago and haven't gotten a response yet...

No. Unless he has a some custom tuning software it's not a usual parameter you can set.

this is another noob question, but can you just get your stock pcm tuned by someone locally?

yup. with a tunner.

how does one go about finding someone with a tuner...lol?

well you can try the south east division on the forum to try and find some locals. if not maybe ask tdcracing. he lives in georgia and if your willing to make the ride and pay up for the tune, he might work something out for ya. but idk. you would have to ask.

but a custom tune would be way better then a canned tune. you would also have to get an 05 pcm. i forgot about that. no software for 06+

it should work just fine.

thanks blowfish, i would def. make the trip to GA. not that long of a drive for me. it would be worth it IMO.
