Well now I've got the same problem as Dee (USMC_Turbo6). When I turn the lights on the fuel correction goes from pretty much 0 (128 on scanmaster) to pulling out the max (115 on scanmaster 10.2% on computer) amount. I've reinstalled the power logger board, ECM pin D11 is empty, my grounds for WB,Boost gauge, alky... all go to the block, and I get power for the MAP sensor as Bob suggests in his video. Attached is a log where you can see this happening. The only evidence I see is a slight glitch in MAP and Boost pressure when the lights go on around frame 565. Any suggestions?
