Done about 1000miles and did some tuning on the software. Feels like I have full power back and mpg loss is circa 15%.
Seems I just needed to get a few miles under the injectors belt as such.
Adaption on the software although isn't the smoothest seems to be doing its job right if a little bit rich.
But I don't mind that. Rather a bit rich than too lean on a twinspark. Especially for motorway. I am sure I could get a few extra mpg on the motorway by leaning it out at low load 50-60mph. But I just have a feeling i'll be cutting it too close.
Especially considering I am running a 1.8 with a 1.6 ECU then using LPG. I don't want the heads to melt themselves down :-)
Saying that because it runs a bit richer. anything above 80-90mph feels far smoother and engine actually feels more comfortable at that speed than on petrol.
