I just bought a ecm for my 91 t/a which I just did a 350 tpi swap into the originally had a 305 tpi in it. However the new ecm doesn't include a prom. So is there any type of prom that is easily available that I can use or might my stock 305 one work? Any help is appreciated.

thanks
Steve

 

craigmoates site under downloads has an assortment of .bins for various platforms. As far as a chip all I can think of is EBay. Or burn your own.

 

yeah ebay was my first thought too, but theres not much on there
