Cylinder Select bypass (ADS memcal)

Is there any way to modify the .BIN so that I can use this ADS Superchip memcal that came with my car with the Moates G1 adapter? I don't have a stock memcal and the ADS one doesn't have the resistors that set the cylinder select. Right now I have a mostly stock ABWN loaded (only changed fuel cutoff/resume to 6300/6000, disabled EGR, changed to manual transmission, set the idle to 850) and no 3D changes. I get code 41. Number of cylinders is set to 0 (correct for V8). Everything is seated properly per the Moates adapter instructions. Car starts and runs... poorly. When I pop the ADS memcal back in without the adapter the car runs like it did before.

Fixed! After reading several threads on the ADS Superchip, I saw where people were talking about putting their homebrew chips directly into the ADS socket without using an adapter. My ADS is an old one (says copyright 1987 right on the plastic shell) that has a removable chip. So I just popped out the ADS chip and put mine on. It worked! I like this stockish tune much better than the ADS one. So, if you happen to be one of the "lucky" ones that has an old ADS memcal assembly with the socketed chip you do not use the Moates G1 (an excellent product for other uses).

So those necessary resistors must be integrated into one of the chips that are in the place of the limp mode chips then? It's hard to tell.
