In the very first post that I quoted in the thread that was edited 10 minutes ago. I guess that clears that up. I assume the injector impedance changed between 92 and 93?
So on to the second part of my post. What is the internal difference in the DIYautotune ECU? They listed the year cutoff at 1991 and up.
