"For 1G DSMLink, nothing. For the 2G guys, the '95-'96 style Cam Angle Sensor (CAS) sends out a signal that's electrically "inverted" from other DSM cam sensors (1G or '97+ style). When you put a '95 ECU into a car with a non-95 CAS, the ECU ends up swapping the firing order of the injectors. In most cases, this produces very little noticeable difference in drive quality. But we offer the option to invert the CAS signal anyway just in case. You can selectively invert this signal with the DSMLink software as you wish. You will still need to swap your spark wires, though. We can't control spark firing order in the EPROM at crank time. So even with CAS inversion, you still have to swap plug wire 1 with 2 and 3 with 4."

My mods are in my profile, and I just swapped in a 95eprom with dsmlink. Did the plug wire swap, now the car will turn over and almost start, then just idle horrible and die. I tried the plug order how dsmlink wiki showed it, and it didn't work. Then tried a couple other ways and still does the same or worse with every combo. Other than the plug swap and inverted CAS, what could cause this to happen?

If you swapped wires correctly then another issue is that the compensation for the injectors your running is way off (or base fuel pressure isn't correct, etc)

Standing in front of the car looking at the engine-cylinders right to left= 1, 2, 3, 4.
Standing in same place looking at coil pack-right to left= 3, 2, 1, 4.

At the coil pack, swap 3 with 1, and 2 with 4.
If you have DSMLink installed, turn the key on and select fuel pump, and this will turn on the fuel pump.
At this point, you can adjust your base pressure to 43.5psi.
No, it doesn't matter if you remove or plug the vac line, the motor is not running, so how could the engine be making any vacuum.

Make sure you have all of the parameters dialed in for your injectors, i.e., dead time and global per the dsmlink user guide recommended settings.
And select invert CAS option under misc I believe, if you are a 97-99.

Make sure your MAF is plugged in nice and tight.
If you're venting your BOV, you shouldn't, fix it immediately.
Your Global for PTE 880's should be -46%.
Your Dead Time should be 330us.
You don't have an APFR per your profile, so your base pressure could be dead nuts or over running and causing you to run rich.
Double check everything, and do a boost leak check for shits and giggles.
Change your plugs if you need too, and gap them to .028".
Check your wires too.
My friend installed a brand new set of MSD's on his 1g, and 1 cylinder wasn't firing.
Swapped back to his NGK wires, and she idled like a champ.
Once you get her to run, do the following to a "T", I did, and I haven't looked back since.
