    Here's mine as it is now. I can read/flash 97+ LS1, E40 LS2, LB7, LLY, P12, 5 speed and 6 speed Allison. I plan to add a connector for T42 and one or both of the other LS2 ECMs. Battery is a 7.2Ah sealed battery, which is in the larger box on the bottom. There is a jack on the side of the smaller box to connect a maintainer up to keep the battery fully charged.

    Where did you get the battery? I like your set-up. Small and compact.

    I got the battery and maintainer from Batteries Plus. It's this one.

    The nice thing is I can toss it in my bag and take it into U-Pull-It yards and check to see if a prospective ECM powers up and gives data.

    I dont suppose you have enough parts to make another one of those? I would buy a setup like that if you did. Let me know.

    I guess I don't get the point of all of this. Could someone explain this to the dum..... LOL dumb. I know the what and the how, but I'm not sure of the why.
