Hi, I am considering chipping my 4.5l GU Patrol and was wondering if anyone here knows if Unichips are manufactured specifically for each vehicle application? I see that they have to be tuned, so my questions is are they all the same generic unit. ie: does just the tuning determine the setup, or do I need to buy one manufactured for my vehicle alone (and no other chip will work)?
Cheers

What I meant to say, is can I just buy one off e-bay for a V8 Holden or Subaru WRX and get it tuned for my 6 cylinder Nissan, or do I have to wait for a specific '99 GU 4.5 litre Nissan Patrol chip to come up?
Interested to try one, but not willing to spend $1,400 on a punt for maybe only a 3% power gain. Apparently, their success varies greatly from vehicle to vehicle.

Hey V8DIESEL,
UNIchips are unique to each car type. Whilst they are a piggy back ECU - they are designed to work within the parameters of a particular car.
Example - some cars run Throttle position sensors and others run MAP sensors - some even run both. Also voltage thresholds for sensors will be different along with paramters for operation. Therefore one piggy back cannot do all.
Also these days UNIchips come with the correct connectors to plug directly into the factory harness.
The reason they are tunable is to cater for different modifications some owners will have along with factory tolerances being different from car to car.
With regard to self learning ECU's - most good tuners and latest model UNIchips work fine with these. I know of plenty of WRX's in the club using them
