Has anyone ever heard of disconnect a wire to stop your car from spraying fuel in sequence and making it spray all 6 cylinder at one time for racing purpose only. if so what wire is it and is the a real advantage

If you loose sync, you can go from sequential fuel injection to simultaneous injection which fires all 6 fuel injectors at the same 6 times per engine revolution. This could other problems, like backfiring though.
If I remember correctly; its been years...... it is the temp sender for the ECM. The car normally uses batch fire when cold then goes to sequential when warmed. Disconnecting the ECM temp the car thinks it is cold and gives batch fire. This is with the stock chip if you have a modern chip it may not work that way.
Rather crude way to gain performance and probably run way too rich.
As Bob stated this does absolutely nothing useful under load. Even if the sequential was out of sequence it wouldn't matter at high engine speed unless certain cylinders were programmed to run with extra pulse width. There's not enough time for it to matter.
