there is some computer plug in thing you can get that allows up to 5 programamble settings using your current computer as the base setup. Than you just plug in a lappy and modify what you need. It's like a motec for $700 that just pluggs into the bottom of your current computer.
I'm getting one when the mods require it there designed for the mustangs that use the same computer but they do work on the falcons (according to the guy in the US that sells them)
I've got the site on my laptop so I'll post later on to give you the site.

 

EECTuner should be able to sort out any problems. Give Peter (XR9UTE) an email at pie@icenet.com.au he is the Australian distributor. It is very similar to the EEC Tuner, but is much more user friendly. What mods do you have on board to throw your computer out of whack? Generally, the EECIV is very good at learning its way around changes.

 

I meant the TwEECer, not the EECTuner. While both do the same job, the TwEEcer is much easier to use.
