Just my opinion but I don't know that logging the TPS position will give you much good info. Logging a map sensor to monitor manifold vacuum will give you more usable data in my opinion and I do not know if the LM2 can do that or not?

That being said I might have an Innovate TPS sensor setup for a holley carb. If I do you can have it, i bought it and never used it before I went EFI. If you are interested let me know and I will see if I still have it.
