Default Sluggish Idle after mods

Hi ppl,
I own a AUII XR8 220kw model. Just recently got a new exhaust system fitted (Metallic Cats, Pacemaker extractors, custom 2.5inch) I have also just replaced the spark-plugs. Everything runs well just lately she tends to be a little sluggish on idle (in Park) & today it was idling fine in park, but when i put it in drive she almost stalled!!! WTF!!! I havnt gottan a tune yet, could that be a problem or could it fix the problem???

You could try resetting the ECU. Here is an article originally submitted by LG on aufalcon.com.

All the best with it.

RESETTING AU ECU – BY LG

WHY DO IT?
Often, resetting the ECU can give the car a fresh start, improving performance, economy and smoothness. It is recommended that an ECU reset is done after any modification to allow the computer to relearn the car and the driver.


PROCEDURE:
Disconnect the battery (Take off the positive terminal lead) for approx 40minutes to 1 hour.

Once reconnected do the following:

AUTO Transmission:

- Start car and idle in this sequence?
- 2 minutes idling with the transmission in drive and A/C on.
- 2 minutes idling with the transmission in drive and A/C off.
- 2 minutes idling with the transmission in neutral and A/C on.
- 2 minutes idling with the transmission in neutral and A/C off.
- Drive the car on the road, for at least 5 minutes under variable throttle positions.

MANUAL Transmission:

- Same as above, except put the transmission in gear for (drive).

After resetting the ECU, your idling problem may get abit worse 4 a couple of days before it gets better.
