V3/4 sti Ecu into bc and bf legacy

[Drunkenmonkey]

Over a long period I have played with running a STI V3/4 ecu in a BC/BF legacy and have the correct A/F ratios well I have now done this!

Car I have done this in is a 89 NZ New RS

I have used

75 V4 ecu

Orange AFM with plug

Yellow injectors

BH Rev D FPR

Map Sensor from wrx/foz or gen2 legacy

Home made a plug and play adaptor for the ecu to plug into the factory loom so its easily removable if need be or relocate ecu if you want to!

These i can make up for members but keep in mind they take about 5 hours to solder up, theres also going to find 4 plug ecus to cut up for the socket and 3 plug looms to cut out of cars

Yet to try a 3 plug link in the car

ECU ADAPTER

Map sensor with short lead from a Twin Turbo

Fuel rail adapter in place of factory fuel pressure reg

New fuel pressure reg

AFM with converter plug

ANNNNNDDDDD BBBOOOOOOOSTTT

Jesus you must have some time to waste .

Why did you do the fuel reg ?

And you do realise 3 plugs from the 4 plug plug into the 3 plug ecu . Can jus re pin half it

My way to achieve the same results on a bg5a tt . Smack in some yellows and a adjustable orange afm . Wide band . Figure out the bulk difference between greys and green vs yellow and orange is as a %and wind afm up or down said %.

It's been done over the course of 6 months bit here and there at night,

I changed the fuel reg cause the base pressure of the first gen pressure reg is lower than the v3-4 fuel regs and it would run just lean, yea I realise that you can just repin it but if you cock it up its hard to reverse where as this is just plug and play,

What's an adjustable orange afm?

Wouldn't it be easier with a adjustable fuel reg instead of doing it electronically
