Hi,

I heard that there is computer chip inside the car that stops it from passing a certain speed limit. Is this correct? Is there any way to fix it so it can reach its full potential if needed?

Thanks

 

Its called the governor's speed limiter (or something close to it). It just basically prevents you from goin past 155 (or was it 160) on most cars. Believe you can get ECU reflashes to take off the limiter.

 

155 is pretty fast already.

 

I don't think the limiter will ever give you a problem. You'd need MILES of road to even get to 155, the car really starts to crawl up there.

 

well the stock ecu does do alot to stop ur car from performing to its fullest...ur comp slowly shuts ur fuel from pumping into the engine the higher thr rpm is...suck the stock limited ur cars full ptotenchel..so i recoment a technocquare ecu for full protnchel...this does alot for ur car asides remove the limter..also chnges fuel mapping rev limiter etc...google technosquare ecu's

Scootch, have you done this yourself?
Does it damage fuel economy? How do you do this also. Is there a dealer that I need to the car to?

Thanks

 

that thing about it not pumping fuel, is it makes the throttle body open like 80% rather than 100% and WOT. But, i talked to some gearhead friends, and they said at 80% you're getting substantially all of your performance, but that if it opens to 100% you risk it getting stuck open.

 

full potential if needed? u r joking right? when are you EVER gonna NEED more than 155 mpg? i hope i dont travel on the same road as you when you are doing that!

to extract full potential of a car, go to the track..and even at a track, i dont see cars going over 155 all that often.

peace..
