Hi Dan, It doesn't appear that anyone ever responded to you on this. I'm not going to be much help, but I can say with confidence that the answer to your question is yes. From what I've read, you can, for example, configure a TPU channel as PMMX that tracks the crankshaft position. Then you program TPU channels with the function PSP12 to control fuel injectors. So the PMMX triggers each of the PSP12 channels at pre-determined crank positions, and the PSP12 function controls how long the injector is open (fuel setting). The trigger to each PSP12 channel is an internal link from the PMMX channel, I believe. You might want to be careful which channels you choose for which functions, there might be some limitations on which channels can be linked to other channels.

A quick question on the TPU. Is there some way to link TPU channels in software so that you can run different functions on different channels all based on the input to one channel? I want to share a single encoder signal with multiple TPU channels and run NITC and FQM functions on them, but I would like to avoid adding wire jumpers if possible. Right now our encoder signal (after isolation) goes directly to a specific TPU channel. Is what I would like to do possible without physically jumpering channel inputs together? Thanks for any help!
