OK so I have a massive milestone completed today!!
Before I get to that I have sorted all the fluid, bled the clutch and brakes and found a couple of issues, first was simple, I had managed to not fully tighten a union on one of the rear brake pipes so sprung a leak there which I had to fix, then the more serious issue was a leak from the brake limiter valve which I could not fix, clearly one of the threads was shot as I could not tighten it enough to stop the leak so I had to replace it, another 100 quid spent and one less original part but it wasn't quite as fiddly to replace as I imagined, I was able to do it without removing the servo (the flexible lines helped).
Anyway, that isn't particularly interesting, but the fact that I got it started is!
First up I turned it over with injectors disconnected, HT leads off and fuel pump fuse removed, after settling my nerves and plucking up the courage I turned the key, and I was very happy to see oil pressure build very quickly, so that was the first part of this milestone passed, I had not expected it to be quite that straightforward.
Next up setting the throttle position sensor in the ECU so it knows where 0% and 100% are, this was simple, I then checked that the crank was syncing, and it was so with this I thought I was ready to rock and roll.
Everything connected up again, some more courage required as even more nerves were building but off we go, start attempt 1 - FAILED. It turned freely and tried to fire, open the throttle and I get some flames through the intake and it then struggled. I could also see the stark plugs were black and wet with fuel and I can see some fuel on the top of the pistons so I'm guessing at the very least it's over fuelled, but it is trying to fire.
Time for a think, first up the injectors, I replaced the stock 150cc with new Bosch 480cc units and I recall reading in the manual for the ECU a paragraph that dealt with changing injectors, some simple maths required to change the pulse width duration as the base map was set up for the stock injectors. Still will not start up but there's clearly less fuel now.
Then I got to thinking it's a problem with the firing order, no clear instructions in the build guide for the order for connecting the HT leads to the coil and I see conflicting info on the web when trying to find out, being bank holiday weekend I thought it unlikely I'd get a reply from SC if I tried them , a couple of different configurations later and still no joy, but I think I worked out which is correct.
So I slept on it and came back to it this morning, I had a thought that perhaps I'm getting too little air in at zero throttle, so I adjusted the throttle so it was slightly more open at zero, I also noticed that the throttle on cylinder 4 was sightly more open than the others so I adjusted this. I used a very thin piece of paper to ensure I had just enough gap between the edge of the butterflies and the inside of the throttle bodies to grab the paper lightly but not so much that it wouldn't slide out. I also reset the HT leads to what I thought was correct.
So back into the car, re-checked TPS calibration, needed a little tweak, less nerves now having attempted a start a few times so I was less hesitant to turn the key, and to my massive surprise SUCCESS, it fired up! it was a little rough, especially at idle, I had not started my video so went back to set the phone up and started it again, and here is the evidence...
I've run it a little longer to see how it goes, it's definitely a bit rough at idle, but not so bad with the application of a little throttle, it also seems to rev freely, as it warms up it gets more lumpy at idle and struggles a bit at times requiring a touch of throttle to prevent it stopping, oil pressure is maintained and no leaks so far so I'm very relieved!
BUT, I'm not sure what to do, I'll get in touch with SC, they may have a base map that is better suited, they supplied the injectors and told me they are what they generally fit to their own builds so hopefully they have a better map. I'm not sure if it's; a fueling problem, the throttle needing a little tweak (either more open or closed at zero), idle speed needing a tweak or maybe ignition timing. Some of this I can see how to adjust, others not so much but where to start??
One thing I have noticed is that RPM reported by the ECU do not match the rev counter, I think the ECU is likely more accurate, rev counter suggests 500RPM at idle, ECU around 1000, it would surely stall at 500.
So jealous.
Also Northernpower and Sonik4 on here have both been incredibly helpful during my build, as they are both building SC 8 port engines with the same ECU. 
the door bins were from bolt on bits on Ebay, I also got rear bins from them which match and are more or less replicas of the bins which were installed in the MPI models, I think they finish the interior off nicely.
I should probably find this out though!
