Thanks for this info, i might look into locating a non hiss ecm , seams like an easier idea. Cheers for your help.

Yea thats what im looking for, im looking to rewire to remove hiss inside ecu. Is there an available diagram showing the hiss showing hiss feeds etc? as during moving house have lost both my keys .

Hi guys, i have a 5th gen with HISS system, does anyone have the wiring diagram for the ecu? Cheers
