Thanks for your reply.
Since you have a powerchip fitted to your AUII XR8, well,,,,,,,,,, does it go better ?
Did you get the xtra herbs they promised ????????
What was the installation like ?
Did they butcher you car or look after it ?
Would you reccomend them ?
Your ECU needs a bit of a make over for that chip to work. On mine its a pluger inner on the expansion port on the ECU. I tried one, still got it (a SILVER one) sposed to take advantage of the cam & extractors as well as make the Knock sensor part of the ECU family to take advantage of premium etc. WELLLLLL it didn work, just buggered up things.
Thats why all the questions.
by the way, your AUII XR8 sounds great, is it as good as they say ???
I have tried the plug and play chip also and was Ho Hum about the result. Best way to go is with a programable interface using a laptop to set up. Motec is the best but as stated above 5g's required, go with a unichip as the next best thing with money being tight.
Lots of people talk about Unichip. Are they not the same thing as Powechip ?. Eg plug into expansion port on ecu ?
If you have used/have one etc, please how much, How do the fit, and what exact details can you give, eg how much increase in power, any increase in torque what model & engine (Mods), economy, would you reccomend them.
Unichip is more than just a plug in chip (into the port on the EEC) it has the ability to be tuned by laptop computer and retuned with further modifications etc. Cost is around $1k and can be supplied by Herrod Automotive, some of our club members have used this system and I believe have no complaints. Give Herrod a call for their estimate on power increases but 10kw should be gained on a stockie.
I have had 3 different chips in my AU XR6 HP. A Powerchip was the first one, that mob didn't tell me that the ECU had to be modified to enable the chip to work. Drove it around for a year THINKING it went better, got a refund after all of that. Next, I was promised a 20kw at the flywheel(approx. 13kw at wheels) with a Unichip, got only 6kw at the wheels. The car already had a set of H.M. Headers and a 2.5in straight through exhaust system on it. Again, I asked for a refund and got it, the Unichip was $1200.00. The present chip in my XR6 is a Chip Torque unit, they thought a 6kw gain at wheels was the go, they got me 9kw at the wheels and the car drives so sweetly through the gears(manual). The Chip Torque chip cost only $600 which included the dyno. I am though having a problem with it, it loses connection to the ECU board and car stops running. The people who installed it are working with me to solve the problem though. The car came in with 118kw max. and drove out with 127kw at the wheels, about 190kw at the flywheel.
Your experience with 3 different chip companies seems farmiliar. Glad Chip Torque came through. hopefully the will solve the loose connection problem. that could be very dangerous.
Those figures are quite impressive, what are your cars' 0-100 & 400 metre figures ?
Hows the feul economy city & Hwy ?
I soke to Ray Hudson at Crow Cams, they have developed a new cam for au/auii, and will soon release a new chip made to match the cam, but I think your setup is way past that already. The also have released a new cam gear sprocket, that replaces the stnd one and makes the cam timing variably adjustable so that you can advance cam timing. Dont know how that works much though.
