Post How often do you reset your ECU?

I just reset my ecu again because I got some hesitations. Not only did the hesitations' gone, the car felt all new again! Maybe it's my head. But heck that thing pulled like it just got 2 JATO rockets strapped behind it compared to pre-ecu rest era! I think from now on I will reset my ecu every 2 months irregardless. If anything just to make the ecu forget the lazy driving habit days....

I reset after every oil change. There's that rumor that the sound of the air being pumped out of the oil filter can trick the knock sensor/ECU into retarding the timing. Anyhow, it's a convenient time to do the reset, and my putt-putt OBS almost feels like it has gumption after a reset.

Never heard of that . . in my expereince, ECU only needs re-setting after something major is done with the system, ie install of new mods like intakes and piggyback devices, etc.

we all know how the oil filter spins on...

I just fill mine to the edge, and spin it on.

When i worked for Q-Lube (before PZ turned them into Jiffy-Lubes) we never filled the filter with oil. We just lubed the rubber gasket and screwed it on.

If you fill your filter first, then don't worry, otherwise some people have had odd problems with their knock sensors.

I do an ecu reset whenever I think of it, maybe 8-10 times a year.

I don't mean to sound like an idiot, but how do you reset your ECU. Just put a Weapon R intake on mine.

Only once since I've owned it and I switched from intake to intake to intake. *shrug* Somehow I can't believe that it's that important...

Can someone please put a comprehensive method on how to reset the ECU in the mods section please!?!

This has been asked too many times for it not to be there.

If someone wants a very reliable (I've never had a problem) method, PM me. If you want my method for the mods section, again, PM me.

-Rez


P.S. I've reset my ECU twice. Got the feared high idle when I did it incorrectly (didn't let it idle long enough) and had to do it again.

[Edited to answer the question. Oops.]

Doesn't ECU resetting give you poor gas mileage, it does on my My99 turbo.

Listen to me, all you doubters!

I can tell you that my car experienced a hesitation from 3-4,ooo rpms after my last oil change. I put in some good old mobil 1 and an additive, did a perfect change and got mucho hesitation!

Well needless to say, I was concerned about this problem. But thanks to the suggestions found in the I-club, I did a ecu reset.

I swear that I got 10 hp out of it. I would say the improvement was easily better than the underdrive pulley I put on!

So try it! It will work!
(oh by the way I had 94 octane fuel in the tank during the reset)

Unhook the negative terminal on your battery and leave it for about 5-10 minutes. Hook it back up and turn your car on, keep ALL accesories,(stereo) off! Let car idle for about 30 minutes. Turn car off and then start it up again. BAM, you did a RESET!

I think my way is way easier. Plus, I am sure that I'm not the only one that does it the way I do it. Just my .02 Cents

Hell yeah, I'm gonna start reseting the ECU when I go to the strip because I too feel the release of power when my car's memory is erased and it has to learn the way I drive it again.

Hey Guys,

The correct method (some say!) for resetting your ECU can be found at:

I just pull up on the carpet on the passenger side. Unbolt the shield over the ecu and unplug the harness. I leave it unplugged for about 30 minutes for good measure. Then plug back in and start up car. Now as far as romping on the gas as soon as 1st startup after reset, or letting it idle for 5-10 minutes....well your guess is as good as mine!
(BTW I don't loose my Radio settings and xover settings this way!)

Thumbs down

chrisC,

I would not recommend doing that without disconnecting your battery. The reason is that the ECU connector isn't really designed as a "hot-pluggable" connector, so there is always the danger of electrical surges to components when the pins mate up at odd sequences.

Wire up a battery isolator and 12V gel-cel for your stereo equipment, if it's that important to you. But hey, it's your car.
