I had my 05 6MT sedan delivered 350 miles from NC to VA on Monday. My wife redlined it that night. Then I read the Manual about the break in. We are taking it easy now. Thanks for the suggestion about the 1000 mile oil change though. Even driving nicely that thing beats the crap out of my 240sx!! Best decision I ever made. Nismo7

 

Question with the break-in period and the adaptive ECU (should this be a new thread?)

I believe the G has an adaptive ECU, the harder you drive, the more, over time it will give back in power... It will "learn" your driving style and create the optimal conditions for you. So, if you're driving like a grandma for the first 1200 miles, aren't you telling your adaptive ECU to treat you like a grandma.

I recall an article written in SCC years back: They first dyno'd their new long-term WRX to get baseline numbers. Then, beat the living snot out of it for the next few thousand miles (trackdays, quarter miles, day-to-day hard driving, etc.) Re-dyno'd it, and the computer learned to give it MUCH more power. At that point while still on the dyno, they decided to do an ECU reset: and lost all of those gains -the power went back to the way it first came from the factory. No matter what they did -it stayed at/near the initial new-car level.

I guess you can come up with your own conclusions on this one, Ideas?

 

onG, after the break-in, get an ECU reflash, either DIY or go to the dealer and they should do it for free, it takes them like 30 seconds to do...

 

adaptive ECU only looks at the last few hours of driving.. 10 I think. Or pop into manumatic which overides it as I recall.

 

It happens to all of us, regardless of how careful we try to be. Nothing to worry about. Probably a good thing to hit higher RPMs a few times within the period.

 

I always send an oil sample to blackstone labs for testing on every oil change in my cars. They only charge 20 dollars and they give you all kinds of information on your engine as well as the average of all VQ-35's they have tested. If you see abnormal wear later on it will be an indication that you may want to get rid of the car before you have big problems. They are very good about giving recomencations with each report.

Anyone see this webpage? Is from a thread on break-in period in the technical and modification section.

 

theres a short-term and long-term ECU memory... so a reflash IS necessary

 

Does the ECU reset only apply to the AT? Is the 6 MT affected in any way?

 

Kia,
Slap some tint and overlays on that puppy and step on it!!!

 

Damn, I'm at 1500....already pushed and haven't had the oil change yet. Looks like I'll be calling Infiniti in the morn.

 

im at 600!!!!! halfway there...

 

The break-in on my 911 is 2000 miles... I've had the car for almost a month now and managed to get 900 miles on it... I would love to have a 1200 mile break-in.

 

I'm at 1030 miles rite now, only had the car for about 2 1/2 weeks. Should break the 1200 mark by this weekend. Getting a free oil change at my dealership, should I do it this weekend or wait closer to 3750 miles?

 

I would do it this weekend. Cannot hurt and Blackstone reports show that it does help.
