Hello,

I know this is not directly related to tuning, but Im building a new harness for the car, and going to run a t1 hall sensor setup, but would like to shield it from sensor to EMS .

Thanks

( having trouble finding RFI specific cable that will work or shielding . Have found lots of JUST EMI shielding ).

thanks

 

Generally hall senders aren't that noise prone, and usually don't need a shield.

Glensgarage.com sells braid that'll work for you, I know I've found it cheaper but the info isn't handy.

 

thanks, ill give them a try.

Any others ?

side note, that braided shield, do I ground it only at one end , or at both ?

( the stock systems Ive seen usually only have on ground ( where most of the shielded wires meet ).

But have been told that If I build a new harness I should ground at two ponts ( end A , at same ground point as ECU , and B -where sensor or connector is , ground to motor )

 

Never ground at both ends.

There are two ways to do it:

Ground at the ecu end to the ecu ground plane directly
Ground at the ecu end but run a separate ground conductor to main ground on engine/cylinder head

I have never had a problem with the first way, but the second gives you confidence that you won't pick up any noise from the controller.

 

Thanks for the help Paul !,

Going to give this a try soon. ( I honestly hate ignition input interference )

 

No problem, and much luck!
