Another option instead of the carbon plenums + div ECUs
Discussion
The fitech site has technical info describing using the different intake manifolds. Dual plane for lower power more lazy driving and single plane for more revy high power applications. ( in basic terms ) I have a dual plane edelbrooke manifold to test with so will be buying one of the lower end fitech kits to try on either my 4.0 chim or a 3.5 to go in a wedge project.
I will be watching it too with interest, but will reserve any comment until the building and bragging ends, and the cars are seen together on a track day.
We need somewhere with some decent straights (?Donington, Snetterton, Castle Combe, Silverstone?) in order to test straight line acceleration and top speed, but some decent corners to test handling, torque and skill. Ideally more than one track day, to make Ole's trip over worth his while.
I would love it if we can all get together some time this summer, including Ole - we will all be honoured to have you as a house guest, Ole, you just need to choose between square rooms and round rooms. I would have suggested the beginning of April, so that Ole can also come to the big TVRCC show at Burghley, but will everyone be ready by then? Burghley is only 35 miles from mine, and over 600 TVRs of all kinds and ages have attended in recent years, including some very special cars. Peter could even get his Vixen out (and bring her in his 1970 turquoise car).
Sounds like an interesting challenge and a lot of fun. I can probably rustle up some spare track tyres on 4 stud wheels for anyone who needs a set.
Peter's Chimaera has massive torque, and whilst bhp gets you top speed on an endless runway, torque is what gets you out of the corners faster (or into the barriers/gravel traps backwards faster, but let's not go there).

How good is the ECU and its spec ? would vibration and heat be a problem .
Most ECU`s are self learning but only up to a certain point ,who will be able to map it ?
Has anyone in the UK fitted this to a performance RV8 with good results ?

You tell the thing what it's sat on and it dose the rest for you
Bye bye RR and the maper
This is throttle body injection, certainly better than a carb... but hardly proper multi point port injection where an injector per cylinder is placed just ahead of the inlet valve.
You typically found throttle body injection (otherwise known as single point injection) on low priced shopping cars (think K-Series engined Metros ect) in the early nineties because it was a cheap way to implement injection and meet ever stricter emissions standards. When compared with multi point injection, single point injection is very poor at cylinder to cylinder fuel distribution and offers even worse fuel atomisation, this results in worse fuel economy and ultimately less power
Even during the 80's & 90's if you bought any kind of serious car you always got proper multi point port injection, single point really was a cost saving stop gap between a carb & injection, by the late nineties as the cost of injectors came down even basic cars moved to having an injector per cylinder and for very good reason.
I really don't see this as an upgrade to the 8 injector 14CUX multi point port injection system, quite the opposite in fact. If you did want to move away from the 14CUX fueling system at least keep the 8 injectors and the port injection inlet manifold. Put the money you've saved by retaining your existing and superior inlet manifold towards an ECU that allows easier fuel mapping and offers proper 3D mappable ignition.
These plug & play bolt on American single point throttle body injection units are designed for carb manifolds making them ideal for muscle cars burdened with a carb, as such they are a desirable and easy to fit upgrade to a carb. But as an alternative to multipoint injection (even 14CUX controlled multi point injection)... I don't think so
Hi , it is called the "fuel command centre" 
Basically it is a swirl pot with built in high pressure pump to feed the efi unit. Not strictly required but thought I'd have it to save trying to sort out another method of getting correct pressure feed. It still uses low pressure pump at tank end to fill this tank.
