Thanks for the welcome (and help).
Hopefully I can keep it logical but with Land Rovers you can never tell.
I have a megasquirt-2 in my 90 4.6 running GEMS manifolds & ignition coils on an ACR top-hat linered block. The 90 is back now with a good chassis but she won't run slow - bad idle- goes rather well at other times... changing down to 3rd at 90mph recently. We did a gps based 0-60 many years ago and clocked 7.2sec, 0-30 in 2.8 can be quite fun. Acceleration over 45 was clearly slowing on the graph :-)
I was not expecting the dis-esal to be quick or even moderate but it is faster than an L-series Freelander or a tdi Disco. It is way faster than the 300tdio auto my Dad had once! But then I think snails were faster than that when it was cold. BMW diesels TD4 FL and P38 peak torque is about 2500 so it has to rev to that for acceleration. As you say once up to speed they are fine. I still can't believe the reported 42.5mpg on the way back from Western-Super-Mare down here to Cornwall via M5/A30 and then back roads uphill/down dale. I may have to get a Ronbox or get it chipped but that is down the line as the piggy-bank is empty after purchase and new tyres.
I do have a Hawkeye Total so some diagnostics ability. Money no object would have been Nanocom Evo and Faultmate MSV as I need to be able to talk to late D1, TD5 D2, Freelander 1 & 2 as well as the P38 and it was a choice between a D2 and a RR with head saying D2 and heart RR. So now I have a Classic (series 1 88 diesel), competition (90) and comfort (P38) :D
Cheers guys
