I've decided to try and join this millennium and delve into the ls platform. After spending a week trying to get close I purchased a tune. on my first drive logging the maf seems to be very rich. I don't have a wideband so I'm attempting to sort it out per EC Tunes instructions in the sticky above. Best I can understand i need to copy my graph and past it to my maf multiplying by %. and do this a few times until I get the rich numbers down. I would appreciate any input I could get to if I'm heading in the right direction......I already miss my screwdriver and timing light.
