Any word on CPU enhancement.
Does it not bother any of you that the car redlines at 4000 RPM in park. I removed my muffers and installed straight pipes with stock appearing tips, When I blipped the throttled to check it out I noticed it topped out at 4 Grand. Hopefully a new CPU will fix that along with removing the MPH ceiling. That should be decided by horsepower not a chip.

I'm sure once the programmer companies figure it out there will either be a chip or just a flash upgrade. Many of the parameters like speed limiter, rev limiter, etc. are things that can be adjusted and saved into the current ECM. I would like to find out if the new Chrysler StarSCAN tool will allow overriding some of the settings.

Anyone know a Chrysler tech with a StarSCAN?

That rev limiter while in "P" is to protect the engine, nothing else. It does no good to rev it high with no load on it, so they limit the revs.

I asked a chip tuner in germany, who I got audi chips from, if they were going to do a chip for the 300c since it is being released in germany. This is his reply:

We are still specialised in Bosch and Siemens ECUs. I have no idea what kind of technologie Chrysler is using over there.

Please find out, what type of ECU Is used. If it is Bosch or Siemens, I might have no problem at all.

Best regards


does anybody know what ecu??? or where it located?

What tires are on your car from the factory? Often manufacturers will limit the speed of their cars to fall within the specs of the speed rating of the OEM tires.

Talk about watering mouths, I was watching Discovery channel (I think) and they had a show about the Autobahn. They showed a RUF test driver doing 212 MPH. WOW! :eek:

Well the car is a little on the light steering side above 120. I have not had enough highway do to that to go faster but I am sure the car will go above 150mph. A speed sensitive steering system would be great like on a lincoln ls. The tire are hr rated just like on the us version. i will be switching to wr or higher rating pretty soon.

Hey you speed freaks, come on down to Northern Territory in Australia. NO SPEED LIMITS out of towns and some good long straight roads. We had a Cannonball Run event over here for a couple of years until some bozzo rich Japanese guy in a Ferrari F40 topped himself, his co-driver and a couple of officials (destoyed the F40 too of course). Then the authorities canned the event.

Hello. Here is an update. I have pushed the car to 250 Kmh which is about 156 MPH.
I think that is the limit of the engine/trans not so much electronic limiter.

As for the ride i changed tires and put the 245/55 18 bf goodrich and it made a night and day difference. car is a lot more steady.

I checked TireRack, and they are even approved for the
stock 300c rims (7" wide)! :D

I'm surprised, because the fattest approved tire I found
in my own clickings were 245s, if I recall correctly. This
looks like a promising alternative. They're probably a
little taller than stock, which I don't want, but perhaps
not a show-stopper.

Best,

George Ferguson
