Yeah sorry.
It's been on stop due to the ECU not 'seeing' the security key, so it's basically finished apart from not running!
Got a stand alone engine management system to install now, specifically for the VVTi V8, which does away with the standard Lexus ECU and can be custom mapped by connection to a laptop particularly if a supercharger or turbo is added later on.
It comes with a 'get-you-on-the-road' basic map and 1BAR map sensor, so no need for a rolling road session.
The diagrams are good, but a a little 'universal' so I'm waiting for confirmation from Spitronics re; the crank sensor, so I don't want to apply any voltages to the new ECUs yet.
The Lexus specific VVTi kit:
Two ECUs, one for the coils (spark control) and the other for fuel control, even has an optional launch control output.
Note the size comparison to the standard Lexus ECU!!

‘Well, I came by a 1993 4-litre Lexus V8 engine and was left wondering what to do with it,’ explains Ole. ‘I spent ages thinking about it before deciding to slot it into an old Omega. Not many people realise the Omega has a very low drag co-efficient [0.28Cd], making it ideal for big speeds while remaining comfortable. And for me it isn’t a car if you have to trailer it, so I’ve driven it here and I’ll drive it home again.’
He’s brought the mega Omega to the Papenburg test track in northern Germany, just over the border from Holland. As test tracks go it’s massive, and as with similar venues the world over, security is high. Manufacturers use these places to develop new products and therefore photography and filming are banned in case we capture some new secret car that we’re not supposed to. Today, however, we’ve circumvented this issue by employing a chaperone, effectively one of the test track’s workforce who must be present every time we whirl a camera, which means that if we’ve got one in the car, poor Ann-Caterine has to be in it too.
The high-speed circuit we’re using today features a pair of 4km straights, five lanes wide, connected by some of the most fearsome banking I’ve ever seen. It rears up at 49.7 degrees from the horizontal and, as Ole has just demonstrated, can be driven with no hands on the wheel at 250kph (155mph), a speed the monstrous motor delivers without even breaking sweat.
That’s not really surprising considering the amount of work that’s gone into this engine. Only the block and camshafts have remained standard; everything else has been either replaced or modified. The pistons, for instance, are bespoke items made by Cosworth. Even the Vortech supercharger has been heavily uprated to run reliably at 1.65bar of boost. The result is an astonishing 1005bhp at 7400rpm and 744 lb ft of torque at 6700rpm.
