Hey guys quick question I'm getting a cms stage 2 cam in my car it's an au II fairlane ghia has the vct engine, do I need to get it chipped or get the ecu retuned after the cam upgrade?

you will probably need a tune, au's are very fussy about cam changes..

I have a xcal 3 flash tuner for sale if your interested..

are they?? ... just the Au's??

The a
u ecu dont seem to like changes to manifold vacuum from mild cams.
E series usually learn to adapt to the change and except cams fairly well but au dont.

good thing then that 'she' has the Au ..... i have the e.....

I have read that basically any MAP-sensed (Speed Density) engine, like the Falcon six (both E-series and AU), is tuned for a specific airflow profile and volumetric efficiency, and any changes tend to upset the tune. The ECU can self-adjust fueling within a fairly narrow range, and the engine should run acceptably well with mild changes. But the f@rt the engine is from stock, the f@rt the tune is from where it should be for maximum efficiency and performance. Cams especially affect this.

Even a stock engine can benefit from a custom tune, especially if you keep it well-maintained and are prepared to use 95 or 98 octane fuels all the time. A custom tune makes a big difference to a modified engine. You can get a decent "desk-tuned" chip for your specific mods from TI Performance for $190 - best bargain going (http://www.tiperformance.com.au/product ... Programmed). I bought one for my EF, and it's excellent. I have since bought the full-house tuning pack to fine-tune it and optimise it for mods I have done since. It also includes a blank chip I will custom-tune for my AU2.

cheers for the responses have decided to go the TI J3 chip with a custom tune just need to get pacie's fitted first
