Has anyone got phase 1 and 2 ecu wiring diagrams please,:confused:

there is some stuff in haynes manual .
what exactly are you after ?

( pin numbers on ecu and what there for).

( pin numbers on ecu and what there for).

My notes:

pin, function
---------------
1, ground
2, ground
3, speed sensor (not essential)
4, battery live
5, idle solenoid
6, to fuel pump relay (other side of relay coil to ignition live)
7, injection relay (other side of relay coil to ignition live)
8, not used
9, TPS input
10, to cold start injector (other side of injector to fuel pump live live)
11, TDC sensor
12, not used
13, DIAGNOSTICS (OBD data)
14, MAT
15, coolant sensor
16, +5v for TPS and MAP sensors
17, GND for TPS and MAP sensors
18, DIAGNOSTICS
19, feed from injection relay
20, batch injector output
21, batch injector output
(note: pin 20 and 21 are connected together)
22, not used
23, idle control valve
24, idle control valve
25, PAS input
26, ???
27, ignition output (to coil)
28, TDC sensor
29, to starter exciter
30, not used
31, knock sensor
32, knock sensor
33, MAP input
35, O2 sensor

Is this for the phase 1 and 2 scoff? Hope this is not for the clio, as ecu different.

I thought the pinouts were all the same ? The ECU's are interchangable, other than for the immob, no ?

Just fitting up this efi , does this ecu need an ignition feed to power up?If so where from -ie pin number?

Dont know if the ecu's are different. All l need to do is power up the ecu.

Earth to 1 or 2 and 12v to pin 4 should power it up. It'll need more input before it'll try to switch relays on, etc. but since I have no idea what you're doing I don't know if that'll be enough. As far as I know all of those ecu's share the same connector and pinout. The diagram and notes I have are for a Clio, and i've used this diagram to wire up an R19 engine in an R5, so they can't be too different.

Cheers for the info scoff.I'll reference off the pin numbers and give it a try.
