DaveFromColorado Posted May 3, 2004 Report Share Posted May 3, 2004 I don't think the 94's can be chiped, as they are the OBD 1.5 I think you have to try to program it thru diagnostic port. --Dave Quote Link to comment Share on other sites More sharing options...
supreme_style21 Posted May 3, 2004 Report Share Posted May 3, 2004 Lumina didn't get the 3100 until 1995. You have a 3.1. Quote Link to comment Share on other sites More sharing options...
THe_DeTAiL3R Posted May 3, 2004 Report Share Posted May 3, 2004 Those cars don't have a chip, period. The stuff that was on the memcal (chip) of the older 2.8/3.1/3.4s is not build right into the main board of the PCM computer. So unless you can find someone that specializes in programming the whole damn thing, you're SOL. Quote Link to comment Share on other sites More sharing options...
DaveFromColorado Posted May 3, 2004 Report Share Posted May 3, 2004 I know a place that they have the equipment so they can reprogram the GM computers, place is talled TPIS and they are located in MN, they usually deal with the newer GM F-body's so it may be worth lookin' into. http://www.tpis.com/ --Dave.

BIGBULS Posted May 3, 2004 Report Share Posted May 3, 2004 Fastchip ( http://www.fastchip.com ) will also deal with 94-95 (NOT 96+) 3100 reflashes on a custom basis. They supposedly leave the ignition and fuel curves alone (so no power gains), but DO eliminate the governor, offer revised shiftpoints (my advice for a lightly modded 3100 is 6K 1-2, 5800 2-3 and 5K 3-4 [to save the engine from extended periods of high rpm running]), raised rev limiter (GM recomends no higher than 6200rpm on the stock valvetrain though......), and can mess with 4-2 and 3-1 kickdowns etc..............so even if your car makes no extra power, it WILL be faster. $350 though.........but CERTAINLY better than nothing (and a good "final" modification).
