If so how?

Other software?

Security light is blinking with no start

 

Yes, it can be disabled with EFILive

 

It won't help the no-start portion though... that comes from from a failed key-pellet or more likely, worn contacts in the ignition switch. You can replace that or you can can do some digging for VATS KEY bypass to see how to bypass it at the column if you don't mind losing that layer of theft protection.

 

In EFI LIVE Search G1201, Set it to None, Save, Flash, Done.

 

If the column issue is fixed or bypassed, you don't need software for this problem. It's a maintenance issue, not a tuning issue.

 

You can't do away with VATS in the tune.
You will need to keep the BCM happy or do some rewiring.

 

I agree with Frost that its not a tuning issue but yes it can be done away with.

 

Totally agree with the first part of this statement. Theft protection in an 4th Gen Fbody??? LOL. Best theft protection, locked up in the garage.

 

Yes. Wires in the switch.

Bypassed it and voilą; problem solved.

Thanks guys!!!!!!!

 

I didn't say it can't be done away with at all.
It can't be done simply by changing the tune.

The BCM tells the PCM whether or not to enable the fuel pump as well as controlling the starter relay.
No return signal from the key, no start unless the BCM is bypassed.

If you agree with Frost then you agree with me too.
