Hi, I know y'all guys already have a post about this topic (image of the pinout to xprog) in my case I'm using the Multilink Universal FX device to read it. Which I'm currently having a rough time trying to establish communication with the MCU(MAC7131) VIA JTAG. My main goal is read the memory of the MCU and change the VIN from their since I don't have the ECM to do the relearn process via witech.
So far, I've tried connecting to it through the PORT A and B with no success at 4 Mhz, to my conclusion i dont think this MCU is supported to be read by this device. My question is: has anyone achieved to establish comm with this device? Or am i better of buying the XPROG?
Sorry if this isn't the section for the forum to post about this subject.
