Ok it seems that we got this to work I’m trying to recreate this exact same set up can either you or the other person in this please help me or just simplify what wires go where I really need some help now I’ve got the resistors and the coils and everything I’m just not having success I just need to see or read exactly what wires go where
The ecu comes with a litte book with a pin out diagram at the ecu

If u can't change the spark edge and dwell times in ecu then there's no point in wiring them in

Adamw you are a genius! The impossible happened and you made it possible! Thank you so much!

Thanks for the reply adamw, I will try that.

I don't know if I'm doing this right but, after trying the 470ohm resistor. I pulled those out and tried a value 10 times less than the pin resistance (389). The closest I got on hand was 10ohm (close to 40 ohms). So after I popped in a 10ohm resistor on just (one) coil, the others were disconnected. On test mode I got the coil to click but no spark came out of the plug(plug was free airing and ground to head). I gave up but then tired to just crank the car with fueling off and I got the coil to fire!
So after loading up each channel with a 10 ohm resistor then bunching up the other side together and crimping it to a wire that goes to +5v out on expansion loom. I get 5 volt output error code 74 and still don't have spark.

Its on the 2k position

The resistance between coil pins 2 and 3 is 0.389

I have moved pin 2 on coil packs from chassis ground to the sensor ground on expansion loom, still no luck.
I don't know if a multimeter can keep up with the output signal on the ignition wire but i believe i measured -0.62 when ecu is not on ignition test mode and switching between 4.77 to 4.89 ignition test mode is on
Also measuring resistance between pin 2(ecu ground)and pin 3(ecu signal) on the coil(unplugged) i got .389

Hello, thank you Adamw for the response, went to go source the resistors with no luck so I ordered them online. They finally came in and went to go install them with no luck on getting the coils to fire. Things I did
Added a resistor on each wire that goes from the ecu ignition output to each coil( i did it right after the ecu plug)
On the other side of each resistor are twisted together crimped go towards the 5v out on expansion loom
Coil pin out:
Pin 1 12v
Pin 2 ground to chassis
Pin 3 to ecu
Pin 4 ground to head
Ecu spark edge is set to rising
Coil doesn't even fire on ignition test mode(coils are brand new from ngk)

Thank you Simon for the reply, The diagram on ecu manual is what I need to follow then? Its says to use 470 ohm resistors but does the watts matter? Ignition x I'm sure its means each individual ignition out from ecu. The little box with the word igniter is each coil i would assume. The last thing is will I be able to use the 5v on the expansion loom for all 6 channels and other sensors being connected to it without stressing it out? I'm sorry for the newbie questions.

Hello, I have wired in new audi r8 coils and cant get a coils to fire, is my link ecu able to directly drive these coils? I'm using the bmw link g4 pnp and audi r8 coils(ngk u5014)
Bmw link g4 pnp random shut down!
in G4+

Hello, I'm having a weird issue with my car that seems to be the ecu. Only after getting car to full temp and only when driving, cruising, or WOT. It will just randomly, and its only the ecu will shutdown completely. I don't get a check engine light once it shuts down. The only way to start it back up is to turn off ignition and turn it back on, then I can start it back up. It does it alot and really out of the blue.
