Mr Stuart, I'm running a DTA ECU, I've got a deal with the guys at T&R, cheap as chips mapping sessions as they like the car for some strange reason, Jim thinks it's hilarious!!
I tried to map it myself on the standard engine and got the fueling pretty good but it's hard to know where to start changing over with the from lambda 14.5 to 13.5 in the map, it's also hard to listen for det when driving along on the road!! Holding it at set revs to adjust stuff is hard work too!! Not to mention making sure the det dip is in the correct place!! Plus I'm not sure if you've seen the DTA system but it's not the greatest mapping system ever!!!
The block, crank, rods, head and valves are all off to Modus to be measured and checked, the head will be CC'd and matched, the Pistons CC'd and matched and machined for the right CR. we've decided we don't like 12.5:1 so Jay's gonna research it and we'll make a decision, I'd prefer 12:1 I think, T&R advised 12:1 as a max so we'll probably end up near there, I'll email Newman (my cam manufacturer) and see what they say is the best CR for my cams!!
