how can i tell it isnt a stock ECU please help ASAP
 
hey im meeting up with this guy in about an hour and he says he is switching to the AEM and will sell me his pettit for 400 and my ecu. i dont know the guy too well and dont know if i should trust him how can i make sure the ecu im buying is the pettit not the stock. he ways it is about 4 years old. also will i notice a diff when i drive the car/? please if anyone cen tell me the diff i would be very grateful. also i heard something about the sodering into the ecu if i unscrewed the lid would i see anything noticable inside.

Pettit ecus should have a "pettit" sticker covering the edges. If it does not or the sticker it torn then i would not trade him!

did you search? i think there was a thread a short while back that had a pic of the 2 opened up side by side. but yes, pettit puts a sticker on the ecu.

EDIT: I'm an idiot

Mine has a big pettit sticker right in the middle of it.

no you don't! The pettit is just a reworked stock ecu. It is a plug in, just like the stock but with richer fuel maps.

I thought it plugged into the stock one....damn

does pettit give you something for giving them your stock ecu or did the previous owner of my car just sell the stock ecu?

:o:

ttpowerd 10-25-02 09:19 AM

you send them your stock unit and they soder (sp?) in a new chip or chips that richen the A/F mixture. You can't do anything with the stock unit because it is now the pettit unit.
stock ship ---> pettit
pettit puts in new chips
now the stock ecu is considered a pettit ecu :)

MazdaMike 10-25-02 09:35 AM

so wait he says its gonna look the same b/c he got it a while ago b4 pettit moved to fl either way did pettit always put the sticker on?

ttpowerd 10-25-02 09:39 AM

Look up the page that shows what the stock looks like internally vs. the pettit. That will be your best bet because it is possible to order just the chips from pettit and install them yourself.

As far as the stickers go, they did it 2 years ago when I bought mine and I think it is a safe guard for them as well as anyone who sells it after the fact so I would assume they should have always done it.

k nm i just called pettit. incase any of u are surious, there is a pettit sticker on the ones modded from 07+ i thinkk he said but the first 2 years they did em, they put a skull and crossbones and wrote for off road use only :) i thought that was a nice touch heh thanks for the help. im off to yell at a scum bag

Mazdamike: Let us know if he tried to screw you. You may actually want to put the ECU in your car for a test. Take it out and see if it performs differently. You can tell when you put in a new ECU from Pettit.

Snook: your ECU came from Texas. It was traded with someone who upgraded to the APEXi unit. It is a genuine Pettit ECU.

MazdaMike 10-25-02 05:15 PM

yea i dont know there were no pettit decals stickers he was willing to swap em for me b4 we sealed the deal but i decided not to go for it too fishy

Snook 10-25-02 06:16 PM

I had the right idea about the pettit ecu I just thought that it plugged in to the stock ecu instead of being soldered on as a different chip. I thought you could just buy the chip but I guess pettit solders it on for you.

Wow Joseph you know more about my car than I do.

btw remember that trailor hitch thing on my car?
Do you think it's okay for me to tow our flats boat with that? I'm not sure of the weight of it I think it's 1000 some pounds and almost 20 feet. I doubt we are supposed to tow stuff but....God how sweet would that be!!

Its more than just a chip...its actually two chips and a daughter board that plugs where the stock micro-p goes, and has two sockets on it, one for the micro-p that you desoldered, and one for an additional EPROM. You can't just take a stocker and do this yourself unless you happen to have the daughterboard.
