Thor into an SD1
Had a query on the SD1 Club forum from a Canadian member who has bought a 4.6 Thor engine complete and intends fitting it to his SD1. Or rather having it fitted, as he doesn't appear to do any DIY. His questions were mainly about MegaSquirt as he was told he would need one - and I attempted to answer those as best I could. Basically, that he would probably need an MS3X.
What I'm really asking here is if it's possible to use the original Thor Motronic stand alone in the SD1? Obviously would need some 'bodge box' to fool it into thinking all the other peripherals were in place. Does anyone sell such a unit?
My thoughts are that to convert to MS on a one off like this ain't going to be cheap, if you've got to pay a pro to do it.

I am researching exactly the same question myself.
One answer is to get Mark Adams to sort the ECU so it runs standalone:

I am going to try to figure this one out, as I think it can be done by altering the settings in the ECU, but it will be 6 months before I have an answer!

Being Motronic (It is, sin't it?) I'd have thought the same problem might have been sorted for other versions? Of course I often think wrong.
It's just that Motronic is pretty good - so not the same need to change to MS as say with a flapper or hotwire. Unless it were to cost the same to alter it to run stand alone.

Not sure, I'm afraid. But the Thor was a BMW development? So they'd likely have used something they knew?ChrisJC wrote:It is the Motronic 5.2.1 which is used on Bimmers as well. So I agree, the problem has probably been solved in a different sphere of interest.

Yes. It was used on the 7 series first, then the Range Rover. I am pretty sure it went on to be used on more BMW's too.DaveEFI wrote:Not sure, I'm afraid. But the Thor was a BMW development?

I'd say it would come down to the costs of having it modified to run stand alone. There are lots of the earlier engines converted to MS, so everything needed quite easy to source. But I'm not sure that's the case with the Thor - which isn't a popular choice for alternative use anyway.
