I did a search but could not find what information is actually displayed on a scantool with the different ecm's. All I have read is that you should convert it over and it will give you more information for tuning, etc, etc, etc. What info does the 86/87 ecm give you on a scantool that an 84/85 ecm don't
I really do not want to do a conversion, I just want the ability to view the car and see if it is running properly and make adjustments if necessary. Can that be done with the 84 ecm
