what is going on here?
since I have purchased this speed pro/FAST setup(struggling with this problem for 2 years) I have never ever been able to use the wide band accurately. I finally ordered a new WB sensor and installed it and the disc, it seems to show actual reading at idle and off idle, but when I go WOT it still shows 9.19:1 air fuel in closed loop no matter how much we move the VE tables. We have resorted to plug readings, and there is no evidence that its THAT rich, we have been moving in small increments so as not to melt it down again like last month. the EGTs show alittle rich(1300) but not 9.19:1 rich and it does not blow black smoke. What is going on here?, we pulled the jumper harness and checked it against a known working FAST system and its correct.....does anyone have a pin out with colors and numbers for the ECT so that I can double check that? How about the ECU? what is the proper way to check the voltages to see if its properly working? any help would be appreciated......BTW, it has done the some thing with 2 different header and exhaust systems, no leaks in the pipes.
