    I probably should give a quick synopsis of the setup. The car is a 1999 gsx with a 6 bolt swap so 1g cas. The car has a ohm harness on it with cop and an arc 2 ignition. I redid the timing belt , which is correct... Thankyou. The car is acting like it’s plug wires are mixed , I replaced the map with a new one , it still acts the same. In a 2g with a 1g cas is there something else in ecm link I’m supposed to account for ?

    cant you just swap the two triggers wherever you connected it into the harness?

    My customer has an ohm harness , I haven’t checked yet to see how he wired it. I assumed that since it’s made for a 2g with a 6 bolt , that was taking into account

    then swap 1&4 with 2&3 and start it up... worry about rewiring it after you prove thats the issue

    I wish I had plug wires and a coil pack to test with , it would make this much easier

    dang! I guess you could email ohm, but it should be easy to probe the wires at the connector and at the ecu and figure out who is who. If they are setup correct by the book, you will need to swap them. If they are swapped already (by ohm) then take a deep breath and go back over the basics. hope you figure it out!

    Its easy to swap the two wires on the 3 terminal coil connector.

    Remove the colored purple or green center terminal keeper in the terminal side of the connector shell.

    Inside with a safety pin or the like carefully release the plastic detent locks inside the terminal shell that hold the terminal in place.
    Then at the same time as lock is released pull the wire/terminal out of the shell thru the backside.
    Swap the blue/black and blue red wires to invert the firing order.
    ( or on corresponding wires on the COP connector side)

    Easy to do and swap back if need be once you re-pin a connector shell a few times.

    yep, and its 6 bolt in a 2g 101... So I'm not sure why ohm's harness wouldn't account for that, but I'm betting 10 to 1 this is the issue...

    What other work did you do besides the timing belt? Did the car come in running?

    Wanted to give you guys an update, the map on this harness is wired into mdp, I had to also clear all of the data logging variables because the map wouldn’t read appropriately. Once I did the map read correctly.

    So you just setup the sensors incorrectly in link? I am still pretty confused, but it sounds like you maybe have it working now? :thumb:

    So normally the baro input is used for the map signal, this harness was wired for mdp. The map signal wasn’t logging either , to fix this I removed everything from the Datalogging screen and added it back
