To start off with My name is Chris and i am from Adelaide. I have been into Alfa Romeos for many years now but as i am also a fan of turbo Japanese cars because of there performance, but the Alfa has always lacked that Performance so i have decided a few years ago to turbo my Alfa Romeo.
I have been looking over a few threads over the years mainly Festy's Alfa and BradGTV's. BradGTV gave up on his setup and sold it to me over a year ago now, since then i have passed on his setup to someone else as i want to start from scratch because his loom was to hacked up.

Currently i have rebuilt my 2.0 Alfa engine with flat top pistons to lower compression, water to air intercooler , also i have a twin 40mm side draft dellorto blow through setup (witch constricts me to 15 PSI) and a ebay turbo as dummy fitted.
My plans are to take off the Blow through setup and Modify a n13/camira loom to Suit with a real time ecu, no distributor and run a crank angle to a 1927a DFI module, E85 Fuel , Higher Boost , gt2876r, water / methanol injection and a few other goodies.

Im going to start from the basic as i dont know anything really about fuel injection.
And i hope this is a good starting point for new members also to learn off.

So i want to start off with the LOOM, im not sure on most of the plugs some i am so i need some help.

Please if im wrong or forgoten anything correct me and sorry if i am.

On my phone and have to go but thats a start

6,8 dont use
7 efi relays
10 coil power ground
11 coil power filtering capacitor
12, 13 ignition module
21 coolant temp
22 narrowband o2
14 MAT

15 to 18: any, mpi all fire at once

Thanks , a few i kind of knew what they where for but wasn't to sure.With the ignition Module i do have but couldn't find it for the photo. will update photos as i go along so others can learn off.

I amuse the narrow band 02 sensor connects to the exhaust manifold ?
Am i missing a oil pressure switch ? or is that for a comira only ?
And am i correct that you power the ECU and LOOM via the ALDL ?

I thought the injectors have a certain firing order ? I've never heard of them firing at once.

yes they all fire at once not sequentually

Install a bung in to the exhaust and screw a single narrowband sensor in there.

The oil pressure switch is hard wired to disable the fuel pump in the camira application, so its not wired to the delco.

Have a look at the power relays and you should be able to see fat power input and ground wires, that probably go back to one of the plugs I said dont use. Remove the plug and unneeded wires and hook the power there.

In a multiport injection the injectors fire at once, each cylinder sucks the fuel in when the intake valve opens and goes bang when the spark fires. In sequential injection they do fire one after each other, but the measurable gains are very little, other than a tiny bit of fuel sticking to the intake walls theres nowhere for it to go other than the cylinder it was intended.

sequential only improved idle quality slightly and maybe emissions when the engine is cold?
