I hope to get his bad one in partial trade for another good spare from me. I will open it up someday and see what I can see. I have another dead 022 version here I got from a van at the junkyard so maybe I will try the soldering trick on it one day as well. Wonder why the van was junked? The problem with carrying the butane soldering iron is who wants to open what might be a good ECU and start applying heat to it far from home with no spare? Once you KNOW it is bad why not. Until then..... I think there is only 1 driver for all 4 injectors. Mark
