I picked up a re-manufactured ECM, part number 1227148, so I can start using a scan tool on my 1985 hotair Buick. It did not arrive with either chip in it. Can I use the stock chips from my '85 ECM until I get the right Calpak and Turbotweak or whichever chip upgrade?

I believe you can only use the cal pak off of your original computer. My mind is a little rusty cause it's been a while since i did my change over.I picked up a re-manufactured ECM, part number 1227148, so I can start using a scan tool on my 1985 hotair Buick.

you swap the small chip into the new ecm, but you need a big chip for an 86 or 87.. might as well just get a TurboTweak chip right away and be done with it..
According to the sticky hot air thread on this forum, its basically plug and play as long as you get a chip for the new computer, and an 86/7 maf sensor. I didnt think there was any need for the wire harness and all the other stuff that the link previously posted says you need?

It is pretty much plug n play I did the swap all it took wastage 86/87 ECM and a 86/87 maf sensor what I did and have now as far as chips go I transferred the small calpack chip from my 85 ECM to the 86/87 ECM I'm running a stock 86/87 chip in it ..... I do plan on getting a chip burned real soon for my specific setup but as of now that's how my ride is running ....

The conversion is as turbobooster says above 86-87 MAF, 86-87 ECM- if you wish to add the MAT (temp sensor), Casper's has a kit for that- or it can be deleted on that part of the chip when it is ordered from turbotweak...

i'm running the 87 ecm with the 84 calpack and a turbotweak chip.. i'm running the stock 84 maf and it never caused any problems- even when i was running it for a while with the chip that came with the ecm from the junkyard (87 Olds is written on the side of the case).. it ran and drove fine like that, i just stayed out of the boost until i got the TT chip- which was the best money i've spent on that car so far...
I was able to speak with the previous owner of my Buick to get the last of the specifics and placed several orders. A turbotweak pump gas chip, scanmaster, and MAT sensor are all on the way to go with the remanufactured ECM and new TPS to update my '85 GN. Plans for next year are suspension upgrades, woo hoo more research.
P.S. will the turbotweak chip be shipped with the plastic holder as my remanufactured ECM arrived without a chip.
