so i have a issue i hope someone can help me with i just swapped my 95z28 camaro ecm to a 411 ecm i had the torguehead 24x installed and they sent me the 411 pcm with a stock tune but i have swapped rear end and different size tires so this is what i used on tuner pro to calibrate my ecm when it was a 95 camaro ecm speedofix.PNG this is using a xdf for a 12212156 os transfix1.PNG its the only thing i could find that looks like something to do with the speedo .
now i have the compare up for both xdf's the 95 and the 12212156 ecm my question is can i use either xdf and just switch the numbers so i can calibrate my transmission speedo or am i completly wrong
so the top numbers are the 1221216 ecm numbers and the copy numbers are my 95 speedo calibrations
