What To Do When Adding Mods

[joncav2222]

I noticed this post over on 4geclipse and really thought it was great and went very indepthp, the guy definetly seems to know what hes doing.

Consider were on the same page as the Eclipse i leave you with this:

-A guy post asking why his car feel like it has lost performance after adding an exhaust and intake.

so i put on a megnaflow cat back and the fujita cai and now it seems like my car lost some of its pick up and go, is there a reason for this?

-Clovisman reply's with this:

Actually you need to disconnect both Positive and Negitive cables from the battery. After they are both disconnected, ground the Positive cable to dissipate any stray voltage. Reconnect both battery leads, Positive first, then Negitive.

Next, turn your ignition key to the "ON" position but do not start the car. The car will go through a reset process. You'll hear clicking under the hood, some dash lights will blink, and your stereo will go through a setup. This will take less than two minutes. Turn key to "OFF" position for 10 seconds.

Start the car and let it idle for 10 minutes, it might idle rough but it will stable out. Turn car off for ten seconds, then turn it back on and drive the car normal for the first 25/30 miles, do not WOT the engine.

This process will allow your car to relearn its new parameters. Any time you do anything that will effect the engines performance, you need to reset the ECU. Whether it's a CAI, spark plugs, exhaust system, etc. But still, any time you do any maintenance on your car, you should disconnect the battery. Computers hate to be shorted out Confused .

- I have deffinetly been left a victim to this and even though Ive know to disconnect the battery after doing so I didnt know it went this into detail.

hmm.. idk if i completely believe that'll work with our ecu..
if that would really work there'd be no reason for controllers.
and without a controller.. i wouldnt really trust any dyno results saying it worked.
its confusing with the "learning ecu"

[doe or die]

it is necessary...the car will eventually try and revert to stock over time....but the ECU does need to be reset, 100%. from what i understand our ECU is a real pain in the ass

[infliction]

alright then i'll try it, all i have right now is the intake, and i noticed a difference with it when i first put it on, but it fadded back

[joncav2222]

im probably guna do it today as well

[Tech_Greek]

It works for less than 3k miles though...my general rule of thumb is before a race that night I'll reset my ECU.

[infliction]

that answers that.
but.. if its done every oil change.. standard oil change.. just call it regular maintenance.

it said that the stereo will go through some kind of set up. What if i have an aftermarket stereo in now and took the stock on out?
