you can get haltech piggy back, its called the interceptor.
aaron (check the tuners' thread) does the tuning on that

thanks for all the advice guys....budget a little tight at the moment so i'll travel down the piggy back for now and upgrade when the cash is flowing a little better :D

POWER FC FTW... cheap and awesome.

AAAHHMEN. Speak thy trooth brother! HA-LA-LOO-YA

I almost bought a second hand Unichip, but went with the Link in the end. You will need a type A Unichip and should be able to pick a second hand one up from someone on here for around $400. And yes, definately use Tim Slako to tune it.

if you want piggy back get a unichip... however, if ya got the cash and ya wanna do the right thing by your car a second hand powerfc would be ideal

A Brand new PowerFC goes for $920 to your door step. A second hand one will obviosuly be cheaper, and hopfully might be picked up for $700-800. When you think about it, For a stand alone ECU, its only a few hundred more then a piggyback system, but has better resolutionm,parameters etc.

Also try Greddy Emanage.. definite piggyback.

Ran one on my S13, worked a treat.. Shaun at Allstar, and Hyperdrive tune them.. can get full 2nd hand units with fuel and ignition timing harnesses for under 300.
