Converting to Megasquirt
Discussion
Well the car is now fully together and ready for mapping (which will hopefully be getting done at some point next week)
Only little hiccup I have to sort is that I foolishly wired the wideband feed to the wrong side of the fuel pump relay so with the battery hooked up the lambda is constantly on, so i will sort the out tomorrow and should only be a 10 minute job. My welding is not too pretty on the air inlet temp sensor bung as well but its not too bad considering this is the first time i have ever welded stainless with my mig.
Good thing is the car cranked and everything seems good so fingers crossed there are not too many issues when Shaun turns up.
Getting excited now
I will get some finished pics tomorrow

Cool work and your thinking on the right lines. However, 'if' you have any problems, don't instantly question your own work as I did. 
It cost me lot's of wasted cash. Also, I've had a Ford coil pack break down 
Which didn't help. For the wasted remedial work done I could've gone Emerald with money left over!
Saying that, it's all running sweet now. Don't want to piss on your fireworks just had 'an experience' and you should be good.

All mapped today with Shaun from MS2 tuning so it is now running and driving better than ever! Only issue was that a couple of my plug leads were wrong and the stepper motor does not work, so will have to try and get a working one to double check it is the motor which is the issue (if anyone has one they could loan me that would be great!). Shaun was right on the ball though and neither issue cost us much time. It was all done and dusted in around 4 hours and he talked me through what was going on each step of the way.
Very happy though and i am just about to go out for another drive

Could I ask how much work it is to rip out the old 14cux loom?
Do you have to cut it open much to keep things such as the oil pressure sensor and otter switch etc or are they in a different section?
No cutting required, if you have a new Megasquirt loom from the likes of MS2 Tuning it is pretty much plug and playDo you have to cut it open much to keep things such as the oil pressure sensor and otter switch etc or are they in a different section?

A better question would be 'are things like Otter wiring, gauge wiring, start and charge wiring included in a supplied new loom'.Do you have to cut it open much to keep things such as the oil pressure sensor and otter switch etc or are they in a different section?
I suspect not in which case they will need to be split out from the existing loom or made new.
In respect of your new map I would be speaking to one of these other gents and blagging a copy of the map. Unless your car is very different that map will do nicely until you are in a position to get it fully mapped. If the donor is hands on they may have improved the map themselves to address things like cold start and crawling in traffic as these are very difficult for a mapper to resolve in a 4 hour mapping session.

So I assume mappers keep files of maps for specific engine specs once they have mastered them saving time when a similar specced car comes in as they just run that particular map and tweak it a bit? I suspect not in which case they will need to be split out from the existing loom or made new.

Both my MS2 installs fired right up off base maps form Phil Ringwood Extra EFI when engine's were stock , you will need a timing light etc for setting up crank timing wheel offset (if any ) however and dialing/learning in your throttle pot etc , my map is wildly different now however different engine higher fuel pressure bigger inj's etc , this all affects your tune greatly which is why I mentioned it , remember if your just cruising to the mapper and not booting the car the tune can be off a fair bit and still get you there safely B roads and motorways are very easy on an engine's unloaded internals 
with a cat fitted less likely however 
if your AFR is overly rich for example the cat will heat up and could get damaged permanently you have been warned
with a cat fitted less likely however if your AFR is overly rich for example the cat will heat up and could get damaged permanently you have been warned After 20 years of fitting emeralds I have literally hundreds of maps to go at, but I treat them as starting points only .. every car I've mapped needs something different.
Unless you're building an engine to a known spec time and time again then your start up map supplied by any ecu manufacturer will be just that .. to get you started.
When you consider that in our tvrs we have v8 engines from 3.5 through to potentially 5.5 litres .. aftermarket plenums, injectors, trumpets, heads, cams, exhausts , turbos, superchargers etc etc etc you can't hope to get a map that's going to work well unless you're very fortunate.

Man's a genius and should be respected as such in my opinion.....and he must sleep in his anorak.

always makes me laugh when you read online and people want to try other owners maps off similar BUT not the same spec engines especially the ricer brigade and the younger gen

This is why when a professional like Joolz has your car to convert to Emerald, he custom builds the loom to suit your car, and has the car for at least a fortnight so that he can get the tricky parts of the mapping, like traffic and cold starting, spot on. My car is an utter joy to drive on all road and track conditions thanks to him.

No doubting the mans talents for sure, i just like the idea of fitting the system myself and knowing it inside out. Man's a genius and should be respected as such in my opinion.....and he must sleep in his anorak.
Would just use a base map to get to the mappers as they are all a fair distance away.
