hi i was wondering if any one knows the advantages of a police ecu . Im sure they would all have different features but just wanted to know if its worth having one and if they do anything performance -wise ...thanks

it depends whether it's general duties or HWP pursuit car etc...

No, nothing. Im pretty sure the only thing all cop cars got was an over ride switch for the interior lights (so they could have the door open getting you on radar without giving away their position)

Ok well i've got a ex cop car (believe it was a hwy pursuit car or maybe used by detective) from what i have heard there is no speed limit (never tested the theory) and that is about it but with my car it hammers when you floor it (even though its done over 300 000km+) but uses a sh*t load of fuel, 250km per tank if im lucky!!!! dont know if thats due to the ecu though. Never got around to putting in the xr6 one i got to see if there was a difference to the one thats in it.

Aside from my rambling on i'd say just get a xr ecu or if ur going to be going at very very high speeds then maybe look into the cop ecu. Think police ecu was tuned for a different diff? maybe 3.23 diff? but not sure.
