You have brought up the E-Rod before, may have been in conversation. I dont think you can use this as a reference really, you arent really comparing like things. Yes, they are all engines but the E-rod is based on the LS3 and I think 52x reluctor and therefore uses a different ECM plus it may have a different flash on it so it can not be programmed and may be unique to the ECM line specifically to meet the CARB or what ever requirements
Since the LS1 came out of an existing car I think people are having issues getting the evap functional even if you feed the fuel level into the ECM, but I may be wrong about that.
What programmable fuel gauge are you referring to?

Yeah he kind of skirted my question about KNOWING whether it was actually working compared to the ECM thinking that it SHOULD work

I have to look at the tank in the back yard to see if it would work, but why not install an aftermarket level sender in the tank?

I dont think the ECM would care as much about the fuel level input being "correct" or sliced as other sensors as the fuel level is constantly changing while the vehicle is in motion so the resistance is going to be changing all the time and I would think not as prone to voltage levels compared to, say, the MAF or MAP
I doubt you could get an aftermarket sender in the plastic tank easily since it is plastic compared to metal like most older vehicles, you cant really just shoot screws into it..... I dont like to idea of modifying stock tanks though....
