I was just wondering what software is out that will allow you to mess with the programming of an LS1's computer? Also, what hardware is necessary to allow you to connect the ECM to your computer to do the reprograming?

Specifically, I'd like to know if you could reprogram a Corvette's computer so that when you take your foot off the gas the throttle will slam shut, just as if it was mechanically actuated, instead of it closing real slow like Vettes do from the factory.

Any info on reprogramming these ECMs is greatly appreciated,

Jason

 

There are several firms working on cracking them but none that I know of or would recommend are advertising it yet. Lingenfelters has been given alot of classified info from GM for their vetter program, but I don't know ir they are doing customer work other then for their own cars.

There is alot more at issue in speeding up the butterfly movement, ie fueling and timing changes also.
The C5 factory cars are running a Bosch management system, and you might check around to see if they are fly by wire or in fact had to go to a cable system to get them right.

 

Thanks for the info Grumpy, it's greatly appreciated.

Sincerely,

Jason
