Probably the most weird post ever... here we go, this ecm is for a geo storm 1992 to be precise, you will say that I am trying to resurrect a little gas saver but the reality is very different let me explain:
I am in to anything that cam be mod or tune, being auto mechanic for 35 years and i being involve in racing all my life, mostly on air cooled vw's, and back on the mid 90's a company specialized on performance vw's brought to the market a "stand alone" that could be tune with 4 knobs and was turbo friendly, never used until few years ago have the chance to install one for a vintage resto and works very good, but noted that the ecu was a regular gm production, the magic on the system is on the harness and the box with the tuning knobs that modify the signal from map, tps, and coolant sensor to fool the ecu for more fuel on boost...
That said my question is since this ecm dont have removable mem cal on them and looks so different to the "standard" gm ecm, my question is if this ecm's are programmable on the board via bench with JTAG? or is not programmable at all.
thanks
