Help: LQ4 retrofit mod/tune I have an LQ4 that is cammed with L92 heads. I have an ls3 intake and Edelbrock 3864(cable driven) throttle body. My buddy is going to be picking up some tuning program, and I was hoping you could tell me which tuning program is capable of adapting an LS3 MAP, ls1 style IAC/TPS, etc all on to my computer (Hardware #12589162 Service #12589463) which had an auto and DWB originally. I'll be using speed density, at least for now, and a TH350.
I've also heard that there are problems with adapting ls3 MAP's to other style computers, such as producing some constant pressure reading.
This is my first endeavor into the fuel injected world so please assume I know nothing.
Thanks in advance.

Why would you expect the tuning software to adapt, your TPS and IAC, those are wiring issues. You need to start with an Operating System, that supports drive by cable for your PCM. Any of the tuning packages that supports your PCM should be able to tune your vehicle
PS IIRC that PCM does not support drive by cable, since it has no IAC drivers in it. Most likely you'll have to change to a 411 or 6243 style PCM to go drive by cable
