I installed my Mitsubishi-Sunautomobile hyper Ground System on my EVO VII.
I put the ground points following step by step the owner instructions.

When I switch the ignition on I heard a strange sound like "tretretrec" then the sound went away. Turne my engine on, everything ok, left the engine warms, everything ok, some acceleration in neutral, everything ok. Now its time to compare with my engine function before the installation. After 10 miles of test all I can say is that my car is the same, no better idle, no better engine function, no better nothing!!! and maybe a little worse than before, I'm guessing here.

Now it is time to verify that strange noise when I turn the ignition at the on position. I left the car off for 10 minutes then put the ignition key at the on position, Oh man that "Trectrectrec" sound again.

What can be wrong?

Any help I would appreciate,

Thank you

 

Did you go back and check all the connections to make sure nothing is arching??

 

Could you give more details? How to check?

 

Hmm weird. Do you have a aftermarket boost solenoid? The GM sensors tick really loud but they dont stop. What about your fuel pump? Could that be it? Somtime a fuel pump will make noise as it fills up the lines or raises the pressure whatever it has to do and then stops after a little bit. If it is the fuel pump your might be going out. Easy fix though

take it to a performance shop and have them re-install it. i bought the same thing as you and i've noticed much better electrical stability.

 

I talked with a Mitsubishi mechanic and he told me that this "tick tick" noise when starting the car (on position) is the sensors and solenoids... he said that is normal.
Weird, because I just heard this sound after I installed the kit, maybe I didn't pay atention before. Anyway, I think the best way is to take out and see.
By the way, Someone here hear this tick sound when switch the inginition at on position?
It is not a buzz sound like the fuel pump, it is a tick-tick sound.
My car is all stock!

 

the tick-tick-tick noise happens, any time you remove pwr or grnd for ~30min+

 

It's a ground kit. The car is less than two years old. Do you really expect an improvement?

Leonar is right, the tick sound went away now.
I will do a small trip next weekend and I will post my final impressions.

Thanks for all
