3.1 mpfi swap

[EdDogg]

Hello guys I,m new to this site but was refered here by a good friend But im having a bit of trouble determining what i need to do with my swap. I have an 82 Chevy Citation ok. and im swapping the 2.5 engine out and throwin a 3.1 MPFI in. I was told i need a custom prom chip to make it work correctly. the engine is coming out of a 1990 Pontiac 6000LE and i was under the dash and noticed a weird black box.. upon further inspection i realized this pontiac has VATS *vehicle anti theft system* and was told now i definetly need the custom chip to get the engine to even run now. My question to you guys if you know is. Do i need this chip? the guy i got the info from about the chip i trust him but a second opinion wouldnt hurt.
Thanks alot guys
Eddie R.

RE: 3.1 mpfi swap

im not sure, i didnt know the 6000 had an antitheft system.

there are lots of different vehicles you can get stuff from for engine support. if it ends up that you have to get a custom chip burned and its going to cost a fair bit, look to another car for the ecm and wiring harness, like a j-body (cavalier/sunbird). they have the 3.1l and a pretty simple wiring harness to adapt.
