I'm Really enjoying This now. I've had a few spirited drives in it recently and am still averaging 39 mpg over last 2200miles. 
?? 
My sat nav display still isn't working, I don't know what it could be. 
I have been offered my old ph1 back in a couple of months so I'm just going to address sat nav and maybe have belts done so I have no drama selling this on. 
Cup spoiler and Whiteline rear arb are going on.. For now.  
I was going to have it Mapped by Engine Dynamics but it goes really quite well already and I just stumbled across 
@bloke post about grp n timing and and map.that has me pretty excited so will be looking at that for the ph1. 
But until then, I plan to smarten this, car number 33, up nicely and enjoy it!
