B3704 Injection Bank Assignment

[Lextech]

I am installing a GM LS type PCM onto a non LS engine. I am trying to install CNP ignition instead of a distributored ignition. I believe I have the mechanicals and wiring figured out. I am trying to change the injector bank assignments. The tune is set for 18736542, but I want 18436572. I tried to change the assignment, and now all of the injectors are assigned to Bank 1. I even tried a Copy/Paste from another tune of table B3704 and still it is set to all Bank 1. Any Ideas? I suppose I could just swap a couple of pins at the PCM, but I figured I would do it in the tune.

Are you on the Caddy engine now?

Actually 2 projects. I'm trying to get CNP ignition figured out for non LS distributor ignition engines.

Can you simply swap the injector wires for 2 pairs of cylinders...?

And ignition.

Well, I have been into table B3704 about 10 times now. 2 times ago when I opened the tune, 2 of the cylinders were in the right place, but I couldn't get the other 2 to reassign. Now I just opened the tune again and all 8 are where I want them

Another question.

Does B3704 also assign the injector firing order or just the ign. firing order?

I thought I noticed a difference in the firing order between a 98 and 02 LS1, but I had the wrong calibration file open. The original message was removed to avoid confusion.

Don't forget about 3 and 2. Injector 7 and 4 need to be swapped and so do 3 and 2. Same goes for the coils.

It would be easier to rewire the harness to match the LS firing order to that of the other motor.
