the above pics is how i exactly i have the loom wired in my car , these plugs came with the ecu so i could replicate exactly how it needed to be,

i then changed the pins around to match the link above and it didnt start that way either

then I'd wire it like this:




so going by your pinout:


1:
[blank] [blank] [1Q to 1J] [blank] [blank] [blank] [blank] [Pin 31 - spark output] [blank] [blank] [blank]

[clutch input (js7)] [blank] [fan control] [blank] [blank] [blank] [1J to 1Q] [IGN PIN] [blank] [blank] [12v]


2:

[blank] [IDLE] [INJ 1&3] [blank] [COOLANT] [blank] [blank] [blank] [blank] [CAS - pin 25] [CAS] [GRND] [GRND]

[blank] [blank] [INJ 2&4] [blank] [blank] [AIT] [O2] [blank] [blank] [blank] [blank] [GRND] [GRND]


db37 needs to match this:








you need to ignore the TPS wiring and the wire on 1C. the wire on 1C is after you build a special circuit for the fuel pump. I thought you said you had a diypnp????

First thing to check - can you connect to the ECU with your laptop?

it wont let me connect it says

com 1 is not currently a valid port , this is usually because the virtual serial device such as a usb to serial cable or bluetooth dongle is not currently connected to ur computer.montoring an invalid serial port can cause stability issues on some systems
