Mines Fitted...Report !!
Well what can I say , the car is just stronger everywhere !!
The shift points on the auto are different , it kicks down earlier and that is with me already having a preloaded kick down cable .
shifts are quicker but not harsh .
the car pulls harder fron standstill but at about 40 KPH it really gets moving .
I locked it in second and saw 7250 RPM on the tacho so the extended rev limit is correct .
I needed to have less throttle to do the same speed as before so I fully expect the mileage to improve as well .
There is no doubt that the timing is advanced ealier than the standard ECU .
Very pleased and worth every cent !!
With the timing advanced it's quite possible that at max horse power revs around 5600 RPM [ I'm not exactly sure at what revs max HP is?] it could make 40 HP more , from the searching I've done they are supposed to give a max increase of 25 Kw and that's well below what the mines ECU's for the GTR Nissan's and the Supra's make .
As an example I had to brake heaps harder for one corner as my speed was up by 20 KPH in the same distance as before , a definite improvement .

very nice

Mine's still makes the rom for our cars but the price is pretty high for the gains
UCF10/11 = ~$1500+
UCF20/21=~$2200+

Well I know someone who may be able to do copies.
Is it possible to get pics of the internals of the ECU u have? I can talk to the guy, who has done custom work on ECU's and see what he can do.

Update:
so far have done 300 K's on half a tankfull , taking in mind I've been driving it harder than normal to check things out !!
Normal for half a tank is about 250 to 280 K's .
It will also now light up the rear very easily , thats with 275 wide sticky tyres on, before it was a real effort to get it to give even a chirp !!
I pulled away on a right turn very quickly and it just lit up and I went sideways through the intersection with opp lock on !!
Kept on it and it was still spinning at about 40 KPH and that's with the traction control on !!
It just shows how much quicker it picks up .
Very very pleased .

i wonder what else it does besides play with timing? one of the little known results of t uning with an safc is the timing increase. by showing the ecu less airflow, it goes on a lower load map which gets more timing. so playing with an safc and a wideband 02 might get some pretty good results.

It advances the timing , alters the shift points of the auto , I believe it changes the speed of the shift itself [ and it feels like it has ] , it alters the mixture , makes it leaner when it was too rich and richer up top when it was lean for cruise mode and the redline is up 1000 RPM .
