This could go in the electrical section as well. The warm up miss that has plagued this car for a long time is gone away for now at least. I have been driving it for awhile now, and it warms up and runs with no hint of the missing and bucking that was in it before. I think it was all from poor main wiring, and none of it from tuning. If you remember, the main fuse blocks are now powered up by relays, and not not through the ignition switch any longer. These are turned on by toggle switches on the dash.
Bypassing the ignition switch seemed to be the key
to success here. It still exhibits quirks at startup that I hope go away when the new tank is installed. It always starts, but I can't seem to find a single technique that works reliably. Some times I have to do a prime pump, and sometimes not. What seems to work, at least for now, is to start cranking the engine with the fuel pump, and ignitions switched off. AFter three or four cranks, it starts if I flip both the fuel pump and ECU switch up. This leads me to believe that the mechanical fuel pump must get going first in order to fill the surge tank, before the electric pump can pick up reliably. I don;t know for sure. This is just sort of specualtion. I will fill you in when the new tank arrives, and I get it installed. I will send photos to Pierre, and he can post them if he wants.Sam
