Hello,
I have a 1998 Pontiac Firebird with a 3.8 v6 engine. This engine still has the IAC valve in the throttle body. I have put ECU part number and operating system below, which I got from the calibration details controller tab. I have had this car for about a year now. I wanted to make some changes to the ECU so I purchased the HP Tuners MPVI 2. However I am running into issues already. It is not auto detecting the VIN. After I cancel entering the VIN and select the P04 GMv6 controller it will read from the ECU. The VIN shows up as a bunch of "y" and the OS page is blank. Yes I did check the advanced view also. I am not sure P04 is the correct option to select to read my ECU but its all I could find on the internet. I also unchecked the high speed read option and took three separate reads from the ECU and I have the same issue with each. So it seems like there is something wrong with the way I am reading the ECU or a problem with the ECU itself. The car drives and works fine at the moment. Does anyone have any idea of what is going on and how to fix it?
