Alright so here it goes. I got a guy who had a 1g swap done on his 2g and now he's swapped back to a 2g using a 1G CAS. Now the car runs with the 95eprom ECU(DSMLink v2) and stock wiring color codes to the injectors and the CAS inversion enabled. Runs like trash, but it does run.
When the 1g swap was done, rather than swap the pins at the ECU like you're supposed to, the guy cut the wires and made extensions on all of them then swapped em' at the injectors. What I need to know is, what is the correct order the wires should be for a 2g using a 1g CAS.
I tried using the magnus writeup to essentially convert the data they provide you with in regards to swapping wires at the ECU, into data I can use to swap plugs at the injectors. I'll post a write up of what I think they should be and why.
Either color codes or number swaps would be greatly appreciated for anyone who happens to have done a number of swaps and just remembers off the top of their head.
Alright here we go. So this is how I'm looking at it. I know I could start at TDC and find each compression stroke and so on. Or just use the firing order but its easier to just ask someone who has the knowledge than go through all of that.
Here's how I see it
4 | 3 | 2 | 1
Injector order from left to right as timing belt on far right closest to cylinder 1
Wire colors @ injectors
4) green/green-red
3) green-red/green-yellow
2) green-black/yellow-black
1) green/red-blue
Color codes of wires at ECU, untouched.
4) green-red (pin 15)
3) green-yellow (pin 2)
2) yellow-black (pin 14)
1) green - (pin 1)
Pin swaps as per magnus
4) pin 15 ]]to pin 2[[
3) pin 2 ]]to pin 1[[
2) pin 14 ]]to pin 15[[
1) pin 1 ]]to pin 14[[
Now what does this all mean for me?
Swap:
Injector 4 with Injector 2
Injector 3 with Injector 1
Injector 2 with injector 4
Injector 1 with Injector 2
Writing it all out at first seemed like a good idea to keep track of everything but its annoying to read over and over again. It all just ends up blurring together and making no sense after a while.
Even if someone could just tell me if I'm on the right track, I'd appreciate it.
Final thoughts --- EDIT ---
Plug Wires are swapped as per the diagram provided but after reading more into the magnus writeup for 1g in a 2g I'm not even sure anymore ...
Now we can read it like this. Stock.
Coils from Left to right
A | B | C | D
A - 4
B - 1
C - 2
D - 3
Magnus says take that factory plug wiring and revise it as such:
A - C
B - D
C - A
D - B
This plug swapping implies ( Magnus )
A - 2
B - 3
C - 4
D - 1
The Diagram above, which I believe comes from ECM states the plug swaps should be as follows:
A - 3
B - 2
C - 1
D - 4
I swear I remembered reading somewhere that the particular order was irrelevant so long the plug wires are sharing the same coil where applicable. Is this true? Sorry for all the dumbass questions. Just trying to save myself a few mins going through the process of figuring it all out on my own.
Thanks again everyone.
