I am re=phrasing my question, now that I am a littlle more familiar with this. My bud says the ecu is adaptive to your driving style and after mods,/break=in you should disconnect and then connect and drive like a maniac. He says you get performance improvement. He has Acura.
Should we do this?

 

you dont have to drive like a maniac

But its always good to disconnect the battery overnight (just incase) after break-in (incase you granny the car)

The ECU indeed is adaptive, i think you might notice a change in the accelerater since it is drive-by-wire throttle...

The ECU will adapt over time however if you decide not to unplug it. On our lexus it takes about 2-3 days of driving before it fully adjusts to my driving habbits (without disconnecting anything)

so in conclusion, disconnecting the battery overnight will help an automatic much more than the 6MT that you have (usually 15 minutes will do but overnight just incase)

Again, you dont need to drive like a maniac, because the ECU will just re-adjust itself once you stop driving like a maniac...which is another very good reason why alot of performance cars w/ autos have Manu-matics.

Rambo - I'm not saying you're wrong, but I was wondering why it matters if you unplug it for 2 seconds or overnight. Either way, you're cutting the electricity to the ECU, which should erase it's memory instantly, right? I've heard this about other cars, and was just wondering the reason for having to leave it unplugged overnight.

Do 6mt's have adaptive ECU's?

Well actually there might be power still to the ECU that is why I think it is good to unplug the power so all the power is drained.

 

ok... how do you exactly do this whole thing? Can someone show me... show me a picture of what I unplug ? and is it worth doing it cuz im near the end of my break in period... i have a 5AT coupe... should i even do it? suggestions... please..

i did it on mine. the tech who im friendly with @ my dealership unpluged the battery for me and let it sit for 6 hours. then he told me to let it rip.

 

There might be some remote battery backup inside the ecu somewhere... for example if you look at a computer's motherboard, you'll see a small button-cell battery in there.....anyway...

What you need to unplug is just the Black battery terminal,
The battery is located in the far left corner of the engine compartment (passenger side) it is inside this plastic cover that you can remove.
Unplug it for 15 minutes and see if you notice any changes in shifting, if not, then you should probably unplug it overnight, then all memory will be reset for sure!

i'm going to unplug it when it gets warm, but quick question.....how hard is it to unplug? i've never undone a battery, is it as simple as lifting the negative (?black?) part up and that's it? then just slide it back on?

Just unloosen the bolt a few turns and pull the negative cable off the negative terminal.

 

rambo---
just got back to work and checked the site.
Thanks for your reply ...sounds like you have good stuff to share with everyone!

 

I read somewhere that you have to unplug it for 8 hours.

 

Sometimes there isn't a battery at all. It maybe that there is a bank of capacitors inside the ECU that retain charge for some amount of time before discharging. So if you disconnect the battery cable I believe you would need to leave an ample amount of time for this to occur. Just my thoughts, I'm gonna try it anyway even though I have a 6MT. Performance over programmed radio settings I always say. [img]/w3timages/icons/laugh.gif[/img]

I would rather pull the ECU fuse so that only the ECU is effected. Wouldn't have to reset the clock and radio presets then.

 

My bud with the acura says he pulled the ecu fuse overnight.
