I had a 44S before my MoTeC came along in 2005.

Here's my experience:

- it idled nicely

- it worked well with my brant alarm

- it ran relatively smoothly, smoother than many other cars id driven with other aftermarket ECUs at the time.. the only thing I didn't like was the fairly aggressive injector cut off when going off the throttle, which was slightly annoying in start stop traffic (caused a little bit of shunting).

- fuel economy wasn't too bad at all believe it or not, no worse than my MoTeC

- the antilag is tricky to setup and requires a kicker solenoid.

- it made AWESOME power and torque.. can't remember exactly but with the Link, exhaust, fuel pump and VF22 (stock everything else including injectors, cooler, airbox), I ran 12.74 at the plex.. in 2004, that was fairly moving.

I had it tuned by Leigh Hynes. I personally wouldnt take a 44S to anyone else. If I had my time again, I'd probably have left my car in its 2004 trim as above, and fitted some injectors and an STi cooler, and not run antilag (which popped my first motor).. as the Link and VF22 setup is the most fun I had in my car in the 10 years I owned it.

I loved it and only changed because the MoTeC came along for dirt cheap.
