Hi. guys. Ivan, my O2 sens. is an Inovativemotorsports wideband, and I just today pulled it and recalibrated it. No affect. I really don't think the injectors are sticking or leaking, it runs clean under load till vacume comes up, then goes real rich. I just checked continuity from the map and pres. sol. connectors to the ecu., and ohm and voltage numbers are all within book specs. Do you think adding some sort of venturi in the hose between the maf. and the turbo would help with velocity? Pin B6 on the turbo ecu wire is brown, and for sure it's puttin' out 10V + at the ecu. no mater what, even with the three ecus. I've tried. Again, I think it's something I've done wrong that I'm not finding. I should have kept better notes on all my testing, am sure I'm doing some of this over. Thanks Yall, S.
Does your Innovative WB have a narrow band simulator output that you have wired up to the ECU? If not, you essentially do not have an O2 sensor going to the ECU. A wideband signal won't work with the stock ECU.
Just for clarity's sake, the proper pin location/id of the idle switch at the ECU is connector B56, pin 6. The FSM abbreviates connector B56 as "c". Also, from what I can tell, it should be putting out voltage around what the battery is putting out. So if you have 10 v at the ECU, that's ok.
