Hi All,
Just a bit of feeback for other H6 owners and Matt.
Had my car tuned by Matt about a week ago on my way down to Canberra.
We had to park in the undercover coles carpark as it was raining, a few funny looks from passersby as we took up 3 spots with the doors open while Matt did his thing with backing up the ECU, tweaking was was to be loaded and uploading the new tables. Showed me on his laptop the lumpy poor orginal tables and the nice smooth replacements. Amazing that Subaru could get it so wrong.
Then it was onto the fun stuff of driving around for about 45 min while Matt monitored and logged the car performance and held onto his laptop on the corners.
After driving around for a bit over a week and doing over 2000km I can say the effect of the tune is very impressive. As others have said the throttle response is smoother and it revs and pulls much more freely. Operation when using cruise control was also substantially improved.
Drivability is amazingly better, gear changing and rev matching is easier and rev wind down after throttle lift off is much smoother. Idle is very smooth 800rpm (when warm) with no movement, almost have to check the tacho to see if the car is running.
Fuel economy on highway driving improved from 8.6 L/100k test run just before tune, afterwards driving from Canberra to Taree 7.0 L/100km with some effortless overtaking and second half of the trip at 7.2 L/100km. Around town havent checked yet but am sure it will be better than before.
Am very happy with the tune.
Matt suggested headers and exhaust system for a best bang for buck power gain, am mighty tempted, but will likely go for a upgraded rear sway bar first.
