Unichip

unichip is a pippy back chip...do a search on unichip and mini ...or unichip and wrx and you see a propble that gets highlightef with your computers self learn system.

There is not enought long term redearch to see if the unichip can cintrol the cpu over a long period of time. your money miht be better spent ina replacement cpu chip and mapping.

V8Diesel have a look at these guys they have a couple of performance devices to choose from.

HAs any body got a 100 series with one fitted.....
how does it go...comments very much appreciated

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.

As far as I know the chips are designed for diffrent vechicles, so you must get a correct chip. Don't expect a lot of fuel savings, but you should get more power and torque.

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
