I converted my 84 to an 86 ecm from the junk yard. I got one of the numbers recommended on the tech page. I added a mat sensor, still have the 84 maf sensor. I had Red Armstrong burn a 93 octane chip for my set up (see sig). And I put in my original cal pac from the 84. On the 84 set up I would get knock at about 14 to 15 psi without race fuel. And now I get knock at 10 to 12 with the new ecm and chip. On the turbo link set at 86 ecm. The numbers jump up and down every second or two. Even the mph every 5 to 10 seconds. It also doesn't start as easy.
Any Ideas??
Thanks
