Wiring Diagram
Discussion
Hello All
can anyone point me in the direction of obtaining a wiring diagram for the Tuscan speed 6 engine. I am interested in the wiring connections for the ECU. I have recently obtained a Tuscan Speed six engine, box and all ancillaries and It is destined for the engine bay of my TR6.
Can anyone help.

Yes.
Its a shame that the factory doesn't think so as they have been very disparaging when discussing my requirements.
I find their attitude very disapointing for a glorified Kit car manufacturer that uses every combination of "Other" manufacturers parts in its cars.
I would have thought that their attitudes would have been more enlightened.
It makes me all the more determined to carry on.
Incidentally is the speed six engine as unreliable as the 4.2 AJP, and being that my engine has 895 miles on the clock, how long is it before I have to worry about re-builds?
Could you also advise of any specialists (read "Independant specialists") that will sell me the bits I need.

I hope you have your hard hat and flack jacket calling TVR "a glorified kit car manufacturor" the speed 6 is probably as reliable as the Lucas fuel injection on the TR6 some good some bad!I would suggest that joospeed would be a good person to contact.
I think that one of the problems may be that TVR themselves may not actually have a wiring diagram as such - it may well be mostly done by people who just "know" it & add the wiring onto a wooden former. They may also want to distance themselves from the fact that doubling a TR6s power output may prove to make it a "lively" handler
As to reliability - well if it lasts for 7K miles, then you're probably good for plenty more, as most of the finger-follower problems on some of the early cars tended to manifest themselves before this (note - as a V8 owner I have had no personal experience of this, I'm only going on hearsay - usual disclaimers apply, etc etc)

I stand by my words.
You should see the car that my engine came from. I always had a yearning for a tuscan but after seeing the damage to this Low mileage tuscan I would think twice. The rust forming in the chassis tubes had to be seen to be believed. and the shell had pretty much disintegrated. A central backbone is all well and good if you're hitting something head on, I wouldn't want to slide a Tuscan sideways into a tree. The chassis outriggers support the floor only, believe me there isn't a lot protecting the occupants.
I guess I have also been left a little cold by an indifferent response to genuine enquiry at a factory with a "Holyier than though attitude."
Once that pretty body is stripped away their wasn't a lot left to get exited about.

heightswitch said:No problem. Oh, the 4-5K for 20K miles sounds about right for servicing a speed six, but you'll need more than that if you need a rebuild
thanks for the info Craig. I have spoken to Julian today who is interested in the conversion.
I have started to save already. it seems that TVR owners need to spend £4-5 k every 20k miles on major servicing (read engine rebuilds)
To be fair a lot of the cost seems to be labour (lots of things are really inaccesible in a TVR), so if you are doing things yourself, and it is in a TR6 (with excellent engine bay accessibility) then costs should come down nicely.
Anyway, listen to Julian & you won't go far wrong....

While you are right about the central tunnel being good head on, don't forget the doors have beams inside which overlap the roll hoop at the back and the windscreen surround at the front, s it isn't quite as bad as you imply!
As for the wiring diagram, I am not suprised that TVR cannot help you as they simply buy the loom in from another supplier, BMW I think, hence you get bits of the loom labelled up for knowck sensors and stuff that TVR do not use - allegedly!
Anyway, good luck with the project and let us know how you get on, that will be quite some car when you are done!

thanks Graham.
I am finding out more and more every day about the bits of TVR that they don't actually make.
I believe that the ECU is produced by MBE for TVR.
If I cannot suss out with some professional help, then I suppose I can always junk it all in favour of a weber alpha programmable set up.
I wonder if anyone is compiling a list of non TVR TVR parts with alternative sources, It seems to me that a lot of TVR owners could save themselves a small fortune on everyday repair items??
Neil Russell.
Also I was thinking yesterday
If these Tuscan engines are so inherently unreliable why do so many owners put up with it all?
If a mainstream car manufacturers engine only lasted for 20k between rebuilds there would be a national outcry???

I was thinking Neil, have you bought the whole car or just the engine? If you have the car then you can just follow the wires and see where they go, failing that the wires *should* have labels on them so you know what goes where, but of course if you only have the engine then you are, err, up a creek!
Why do we put up with the engine "unreliability"? Basically because we all hope that the problems are now all sorted and all our engines will now last a lot longer than 20k miles, it is a thing called blind faith and also believing that TVR could not possibly be selling an engine with such a short life span as it will come back to haunt them and could cause them to go under, so we have faith it is just a reputation fuelled by The Internet (I read it on the Internet so it must be true)
As Ben Samuelson said to me once "Don't believe all the people the Internet tells you Britney Spears has slept with"!
As for the alternative buying list, yes it could help, however TVR are not too bad when it comes to selling parts, so it is sometimes cheaper to go to TVR than an independant - really!

I bought the engine, complete with box , gear lever, prop, exhaust, cats, tanks, pipes, engine loom, ecu complete. the engine loom has a multiplug which connects to the rest of the loom. The rest of the loom is what I am missing. I will probably try to get the rest which will make things a lot easier.

'Fraid not. Definitely not a Ford item.
I'm a Ford Electrical / Control specialist and have been making dyno. harnesses from Ford wiring schematics for 17 years.
I've been led to believe Vauxhall may be the OEM for TVR wiring looms, but having dissected some to produce my own wiring diagrams, I reckon this may be wrong too.....
