I want to reset my ECU but i dont want to have it done by the dealer. My friend whom has a 06 Infiniti G35 said there should be a way to do it without using dealer assistance. please help...

 

reflash... or disconnect the batt. for 15mins depending what the problem is

 

no problems, after putting on my headers and exhaust i would like to reset. i was told if i reset the ecu and drive the car hard, the ecu will adjust the to the changes after 30 or so miles to harder driving condidtions making acceleration, fuel management, and air flow a little closer to my liking

 

It's supposed to "force the computer to re-learn"

If you reset your computer, I honestly don't see what it's "re-learning" with a change like a intake and/or exhaust changes. They are MINOR changes.

 

just disconnect the battery for 15. apparently its in the instructions for installing gmpp exhaust

 

Ive read to also hold the brake in too after you disc. the battery...

let me see if i can find the thread...

 

reset it back to stock? I think you need to have a dealer or person with software flash it with the latest gm file. i have the vector tune and i have cleared CEL's by unplugging the battery for 15 minutes but my tune is there still.

maybe you mean just to reset CEL's. listen to the guys above.

 

The reason for him wanting to do it is not for a maintenance or code being thrown issue...he made modifications and was "told" to reset his computer.

 

O2 sensors don't read any flow characteristics, that's the job of a MAF sensor pre-combustion. O2 sensors (narrowbands) read on a head range and communicate to the computer in voltage according to heat measured. If someone just changes their exhaust manifold, it's not going to change anything but the velocity and scavenging effects of the exhaust system. The first O2 sensor is ONLY used for gas mileage purposes which means at idle and low cruising speeds / throttle positions (which is known as closed loop). When under full acceleration, it enters power enrichment, so it IGNORES the O2 sensors for any type of fueling purposes and only relies on the air metering device (in your case the MAF sensor).

So in short

The first O2 sensor is nothing but a way for manufacturers to revolve around 14.7 air / fuel, the second O2 sensor is only for knowing is your catalytic converter is clogged or not. That's it. It has nothing to do with flowing characteristics.

To address the first part of your post about deleting codes...

He is NOT resetting the computer to get rid of codes, he's only doing it because someone told him to do it when making a modification.

 

I think you have a serious comprehention problem.

I stated that a O2 sensor reads on a heat range for FUEL ECONOMY ONLY. It is not relied on for power enrichment. If you put a larger exhaust system, it won't make a difference to the O2 sensor because a larger exhaust system does not change your a/f ratio, only the velocity and scavenging effects.

I DID NOT say that a intake and exhaust manifold change seriously effects power...

Where did you get a manual from? He was told this personally to do so, you started for some reason talking about 06 and 07 service manuals...it has NOTHING to do with the topic.

 

I did

It took me so long to respond cause I was dumbfounded by the retardedness of your post.

 

I guess, if you call that a win lol

 

Well, yeah. Unplugging will cause you ECU to basically start over from scratch and it will take time for the computer to optimize its settings. However, by the logic that the car is making adjustments based on the it's sensors inputs... Don't you think that after making the mods that it will eventually adjust to the mods you have made if they affect you intake of air and fuel?
