I installed an astrostart 5204U in my car when I was going to Mobile Dynamics up in toronto. I moved the system into another car and I need to reprogram the Tach from a 4 cyl to a 6cyl car but I lost the installation manual with the programming instructions, and astro-flex wont give me the programing procedure because of safety issues.... anybody know where I can get my hands on this info?

First learn the tach. 1, 5,6,and7 up. start the car with the key, hit the brakes unit will flash LED onboard # of times. After , then put the dips down hit the brake and shut the car off.

to set # of cyl. for 6 put 1, 5,and 6 up. hit the brakes....the onboard LED will flash, when it's done put the dips down hit the brake. done.

If you want a copy of the install manual, PM me your email address.
