Hey guys need some help on this ....

Okay so the 95 type eprom ecu came in the mail today so i went an hooked it up to my 99 gst hoping its in perfect working condition. pluged all the wires in the ecu, fired it up an it doesnt start... go on tuners an it says to switch spark plug wires #1 with #2 and #3 with #4 so i do an the car starts, but the car will bearly stay running.....Im waiting to send to dsmlink an i did select the the cas inversion option... A couple questions is should my car still run really bad even with the plug wires switched or is there actually something wrong with the ecu?????? will i still need to keep the wires like this even when i recieve dsmlink??? will the cas solve this problem an should i just go ahead an send it out?????
Please help wisemen.....
THANKS!!
Regards Paul

 

try swapping 1 with 3 and 2 with 4. supposedly order is not important but it was for me lol. other than that make sure you are swapping the correct wires. make sure you are numbering the wires by what cylinder they go to and not where they are on the coil pack.

 

tryed your way and it just did the same thing as #1 to #2 an #3 to #4 .. it starts but runs really bad ....Another thing i dont know if it matters but i still have the safc in an its showing that the car is at WOT when i swap the ecu's out ............
need more advice .....

 

did you number the wires correctly? i beleive cyl 1 is on the right and cyl 4 is on the left.

 

yup as 1234 from the timing belt lookin at it from the front of the car
