OK BMW and Chrysler have a governer that turns off at 3000-3500 miles. My buddies Mini turned off at 3500 miles and he said it felt like a turbo kicked in - my other buddie has a PT curiser and his shut off at 35000 miles too when he was on the highway - he said it was like a supercharger kicked in.

I am pretty sure in both cases that the engine timing was turned back and it is possible that WOT was limited to give the engine the proper time to break in before they allowed them to open it up.

The question is has anyone noticed this yet on their crossfire?

no such thing....a governor doesn't just turn itself off...unless new software is involved/introduced to the ecu....even if the governor was removed...no turbo effects would take place.

even after a car is broken in...this does not happen at one given time or set mileage.

he is clueless imo.

 

hmm... after your responce I seeked some professional advice. I know some drag racers and they said most vechicles do have the timing set back untill somtime after 3000 miles for break in reasons at which point the timing advances and it will be a noticble thing, but they said that WOT is not ever closed off...

So the question still remain open - has anyone noticed a difference in performance after 3000-3500 miles that has not altered their chip..

The only things that changed the performance of my car was chipping and K&N filters (so far.... next will be exhuast mod).

 

Okay... you've had almost two whole days :roll: and haven't told us how you did this past weekend. :wink: Especially autocrossing with the G-Tech inside... 8)

Do tell :!:

 

I've been waiting for them to post the video from Sunday so I could post the link too.... But here's a report on the G-Tech..... I only did Lateral Gs. I wanted the video with this (will put it here when they get it posted) because a really cool part of the course this time was a marked skid pad. We went 180* around it. That' where I pulled the most Gs... 0.92... I'm hoping that you will be able to tell from the video that the car was right on the edge of losing traction. It really felt great!!! This course was the fastest one I've run on so far.

This weekend (Mother's Day) is my next one. It's the Corvette club this time so it should be a fast course too... I can't wait!!!

 

No.

 

DC vehicles have no break in period for the software.... Older cars had a break in period for the transmissions, but this was disabled years ago.

Most cars improve in performance after a few thousand miles due to engine break-in. If you read a lot of car mags- you may have heard them refer to a car as 'green'... meaning it has not yet broke in.

And yes- I feel a difference in vehicles from when we PDI them (inspection done upon delivery from DC) to when we see them back a few thousand miles later.

 

I hear that the best break in is running the car like you stole it the first 10 miles of the engine because it heats up the cylinder rings and seals them tightly against the wall. Doing that will give you a better performing engine. Going easy on the car for the first 600 to 1000 miles or so will give you a longer lasting engine but less power.

 

that's exactly what i did.

 

Which one? The first or second?

 

OK, I have read all the posts above about the Xfire having or not having a governor or some HP reduction device. All I can say is I had my oil changed at my dealer this afternoon at a little over 3,000 miles. I pulled out of the service lot, kicked it as normal and the almost wrecked. My baby took off like a rocket !! (more than normal). I'm not clueless and have not had any wine yet today -- but, darn it something sure changed !! Has anyone followed up on this since Jamikest's post in Feb...??

 

i'm not sure i'm allowed to have an opinion here since i'm not a self-proclaimed expert and i've only been driving cars/trucks/motorcycles and airplanes(just started the airplanes) for 40-odd years but yes, i thought the thing got some stronger legs after a few thousand miles.

Why don't you ask the sevice manager?maybe they readjust throttle linkage or?

 

Maybe it's a safety thing they want you to get use to the car before they give you the total power!I think it's in the service.

 

I am half way there to finding out for myself..

Hello all, I just returned from Normandy (D-Day) ceremonies. I noticed that my car was driving funny having set at the airport for a week. I phone the chrysler services team and they advised me to bring it in. They were unable to find anything wrong. The service guy (Nick) said that he would hook me up and proceeded to connect this module under my dash. I noticed the bars and some percentages on screen. He stated that he would reset the cars settings but make some other fun adjustments. He then gave me the keys and advised me to return Monday. I left the dealership and drove 1 mile in traffic to the auto bahn. My CAR IS NOT THE SAME. It is by far much quicker from start and accelerates faster. I'll ask Nick on Monday to explain this and post here then. The service team here is awesome!!!

 

I was also advised by the service team to not pamper the car. The dealer told me to keep the car beneath 4000 rpm until I had driven 1000 miles on the car. The service team said that this would result in power loss.

 

where can i get a box like that !!! lol
Its like Knightrider and the overboost!

 

I'm looking forward to that 3000 mile kick (only at 320), but the other question I have is whether the K&N filters make a noticable diffeence?
