i bought a car that had a hypertech but he lost the book where can i get some instruction.

 

plug it in, turn on the ignition and follow the on screen instructions.

 

It's Just that simple huh? damn whodathunk it? thanx man

 

Just remember that you must have a battery that is fully charged, programing with the hpp really drains the battery and a battery charger can induce noisewhen programming or provide a voltage that is too high for programming. If the car goes in to the dealer for service remove the hyper tech programming. I wouldn't use the hpp+ for anything except tire size/gear change and fan temp enable.
