The problem with this idea is those with a 2.8v6 most likely don't need a whole new engine management system..
and it only be plug and play with that, or if you had them make it plug and play for the 3800s/cseriesII swap with a tv cable controlled 4 speed automatic.. for example as I'm thinking the connectors on a 3800 series III s/c are different than a series II or a 3800n/a series II then different for series III n/a, the electronicly controlled automatics would have connections, and not sure the connector plugs are the same on all years, then the fiero 4-5spd g6 6 speed..
you'll need 9-10 owners with the same engine/trans combo.. and there are how many different ones just in the 3800 swap world??
you might get the integration of the M/S to the fiero harness to control the a/c cruise/gauges/idiot lights IF it's all wired the same in all v6 fieros , and the engine end if you find 9-10 people with the stock v6 and/or 3.1/3.4 swaps that used the same connectors as the original 2.8 and after reading the little I have on the 3.4 swap it seems many sensors are in different spots,
I'm "assuming" this is based on the msIII as you stated "self learn" they are not cheap... and for a stock 2.8 or n/a 3.1, 3.4 with batch fire or bank fire efi, it's over kill.. the msII will handle all that and ign/spark.. sure the self tune part is nice and all but the msII leaves you with at least 500.oo
in your pocket to pay someone to program a tune for you.. or learn
does the msIII pro extra able to control an electronic trans??
you need to ask a bunch more questions, starting with cost.. bet it's 1200-1500 +for a plug and play msIII and harness and nothing else, you'll reuse all the stock sensors (other than changing to a wide band o2) your injectors,t/b etc..
a msII is last time I looked 258.00 relay board50.00 and harness 80.oo , cable to connect it to your laptop, and it'll do the batch/bank fire efi and ign spark.. but no self learn, or trans control..
now if you where doing this for a 3800 s/c swap, to run, sequential efi, and sequential ign control.. it might be worth the cost.. for the self tune, and all the other stuff it can do, data log,control a 2 step, nos, and if it can control transmissions.. then fine 10 people and hope all the connections are the same..
I'm willing to bet someone on the forums has a tune for a 2.8 v6 to get a person started and learns to tune the MSII so you would not need the self learn..http://www.msextra.com/http://www.msefi.com/index.phphttp://www.diyautotune.com/faq/faq.htm#wherestarthttp://www.diyautotune.com/faq/faq.htm
it also is overkill..
