Converting to Megasquirt
Discussion
Cheers for all the info guys, lots to look at 
Thankfully I already have a y-piece from Clive that has a wideband bung welded in, so I think that will be the first thing I get as it would be interesting to see what the 14cux is doing at the moment.
Loom wise I would probably be happier to make the loom myself, I notice their are kits on the megasquirt v8 site but the shop is closed at the minute, so don't know how much they are but they look like a good option.
I have looked at the American site, but can't see a lot of the rover v8 stuff I would need, and tbh think it would be easier from a UK company.
From the looks of things I am looking around £600 for the ecu kit, a couple of hundred maybe for the loom and another £200 or so for a decent wideband. Need to start calling around when I get home and get some proper prices and some bits ordered up

AEM wideband bought and fitted, very nice bit of kit.
Have also just ordered a full MS2 setup from Phil at ExtraEFI and Shaun will be making my new wiring loom!
Should be an interesting experience but still a bit nervous about the mapping. Sure it will be fine once I get stuck in though

Met a guy, engineer by trade, who had supercharged his 4 litre Chim. We went with a few other TVR owners to a Megasquirt demo given by Shaun. Shaun was looking for cars to demonstrate on, or which the owners wanted to have looked at, and te engineer volunteered his car as he felt it wasn't quite right.
Transpired that it was dangerously, engine- threateningly dangerously, lean at higher revs.
Be careful.

I have but I want to learn how to do it myself really. I deal a lot with computers and PLC's at work but car wise I have only ever mucked about with carburetors so EFI is something I would like to learn.
It's not worth the grief.Shaun will load a temporary map, start the car, make adjustments as it's warming then within an hour of mixed driving it'll be done.
As said, not worth the grief of a poor harmful map.
Rather do the above, learn how it all works and then make fine adjustments as you upgrade the engine.

Wasn't that Sappers turbo jobbie? Lunched the clutch at the Pod later that day?Transpired that it was dangerously, engine- threateningly dangerously, lean at higher revs.

But the same warning applies, OP - start your Megasquits experience with a known map that suits the car.....or suffer the consequences!
Mine is normally arsepirated, but when I had my engine changed the map wasn't correct and ran dangerously lean above 4700 rpm.
As luck would have it it I had an RR session booked for lunch time on a track day, and discovered the problem before we had done more than one or two top speed runway runs at RAF Marham
You back on shore for a while Richard?
