Thread: Security tuning question

How do I disable security in pcm.... I was told it was turned to false in secirity drop down menu and the number value is set to 255... I think factory is 0 the problem is the car cranks consistently but dies 3-5 seconds later... It doesnt try to continue running no matter if I peddle gas pedal or what... Ive tried everything and all is left is pcm.... And my tuner is thinking security is issueso help please

i have no idea what a vtb module is... im working on monte carlo ss 2003 model

I don't remember the exact name. Look for something like injector pulse disable timer. It'll be set to something like 4, IIRC it's 0 you want. That keeps the injectors from being disabled by the pcm.

ok.. and does this issue sound like a crank or cam sensor issue? the car starts consistently and dies in the exact same time frame.. 5 seconds from running to death

Not at all.

Cam sensor gives the engine a 1:6 chance of starting, crank sensor also has different symptoms.

alright last question.. will any serial to usb adapter work for the dhp tuner or does it absolutely have to be keyspan

I have a radioshack one. I've heard that some didn't work, not sure which ones. A few guys I know had the shack adapter and I just bit the $30 bullet on it.
