Hi I am working on a 1976 ventura I swapped in a 1992 Camaro TBI 305 and 4l60. Mods are 086 TPI heads with porting, good dual exhaust no cats, injector spacer, open element air cleaner and adjustable fuel pressure regulator set to 14 psi. stock injectors.
I put in a TBIChips prom a few years ago but it does not run that good. So I am going to tune it myself.
I have a 1227747 ecm with adapter soldered in so I can burn AT29c256 EEProms and also have another ECM and some 2732a Eproms for the final tune. And have winaldl, tunercats, & tunerpro software. Several years ago I burned a few stock bins onto a 2732a eprom and tested it out the car did run with those. Yesterday I did a few test burns of some stock bins onto the AT29c256 EEProms, the car did not run good at all, barely got it to start.
I believe I am not getting the offsets correct. the GQ-4X programmer software has a button labeled (01....ff) fill buffer with data. I put in 007000 for the from address hex and 007fff to address hex and ff for the data window.
Can anyone tell me the correct offsets for a AT29c256 and a 4k bin?
