Hi, I've been lurking and hunting around trying to decide how to control this 7.0 tall deck I have. The emissions sticker says 1995, but the original truck was sold in 1996. I'm thinking this is some weird stop-gap that GM did, because there was what looked like an OBD2 connector, but nothing I borrowed could read it. I can't find any pin out info, or anything else on it for that matter. What say you? Throw it away and get a 1227747 to learn on? (PS. I'm a total newb to computers if you couldn't already tell). I'm not trying for any earth shattering tuning, I just want it to run right and get rid of some of the tbi characteristics that drive me crazy. This will probably go into a coe car hauler in relatively stock form, except for the exhaust system. Any helpful opinions much appreciated. Thanks!
