Well Took it out for a quick spin at lunch today. Plugged in the ECU and everything started and ran perfectly! which is good news.
gave it a little bit up the main road and it has a bit more top end actually - infact in auto it shifts out of 2nd at 7,500rpm! pulled hard all the way and I was going over 120km at that stage so didnt want to keep the foot planted. It feels the same at low revs, mid range seems a little stronger (could be my imagination) but definitely pulls better up top and just keeps revving up to 7,500 - which is weird because the sticker on the ECU says 7,000 rpm.
Anyway I think I got a good bargain there!
Now its time for the high flow and dump so I can really make use of this ECU.
