So how do you tune it live? With a piggyback system or are you changing the program in the encrypted Motorola chip? How do you do it? I'm not gonna click on any links. Why not say how your re-tuning your Rex Regina volvo. Or I guess you haven't...
I'm honestly very intrigued, but I think you might be getting ahead of yourself. How do you connect Rex/Regina to Fenix 1 or 2? The trigger wheels are both 44 teeth, and they're map-based...but I'm not sure if the code is the same. Fenix 1/2 seems to be from the mid 80s, and Rex/Regina was used up to the early 90s, which is a huge gulf of time when you're talking about EFI technology.
Do you have any bin files from Volvo Regina and Fenix1 or 2 to compare? That'd help .
I asked how you are reading the chips in the ECU. How do you do that? Can you tell me that so I don't have to read 10 PDF's.
What is the chip in the regina ECU that you take out of the socket and read the bin from? Or do you have to Jtag it and power it up and read it that way? How do you do it once again? There are only a few ways to read data on chips, which way you doing it? How would you then reprogram it? I suspect there are only surface mount chips in the Regina. Good luck Regina lover. I could help..
